ABSTRACT

RESUMO Objetivo: Analisar retrospectivamente as alterações na ceratometria e no astigmatismo corneano obtidas após cirurgia de implante de anel intraestromal, comparando o uso de um segmento de arco longo versus o implante de dois segmentos de comprimento de arco tradicional. Métodos: A partir de um estudo transversal, obtivemos os dados de 94 olhos de pacientes diagnosticados com ceratocone, que foram submetidos ao implante de anel corneano. Eles foram divididos em dois grupos, dependendo do tipo de implante recebido: Grupo A, um segmento de arco longo; Grupo B, dois segmentos tradicionais. Todos os segmentos implantados possuíam 250µ de espessura. Os dados do pré-operatório dos dois grupos foram comparados, para garantir que as amostras eram similares (as diferenças encontradas entre os dois grupos não eram estatisticamente significativas). As variáveis analisadas no pré e no pós-operatório foram acuidade visual com correção, ceratometria, astigmatismo corneano e refração. Resultados: A amostra que recebeu apenas um segmento de arco longo (Grupo A) obteve redução da ceratometria média de 4,42D (8,7%) e do astigmatismo corneano de 2,43D (40,4%). Já na amostra dos olhos que receberam dois segmentos de arco tradicional (Grupo B), houve redução média de 2,66D (5,1%) em relação à ceratometria média e redução média de 2,11D (34,8%) em relação ao astigmatismo corneano. A redução obtida na ceratometria média no Grupo A foi maior que a obtida no Grupo B (diferença estatisticamente significativa). A redução obtida no astigmatismo do Grupo A não foi estatisticamente significante, se comparada com o resultado obtido no Grupo B (considerando p≤0,05). Conclusão: Foi demonstrado que o uso de um segmento de arco longo possui maior capacidade de aplanação corneana, se comparado com o uso de dois segmentos com comprimento de arco tradicional. Em relação à redução do astigmatismo, os dois grupos mostraram resultados equivalentes.


ABSTRACT Purpose: To retrospectively analyze the changes in corneal keratometry and astigmatism after intrastromal ring surgery, comparing the use of one long arch segment versus two traditional arc length segments. Methods: A cross-sectional study obtained data from 94 eyes of patients diagnosed with keratoconus that underwent surgical treatment with corneal ring implant. They were divided into two groups according to the type of implant received: one long-arch segment (Group A) or two traditional segments (Group B), both 250 microns thick. Preoperative data from the two groups were compared to ensure that the samples were similar (the differences between the two groups were not statistically significant). The variables (pre and post-operatively) analyzed were: best corrected visual acuity, keratometry, corneal astigmatism and refraction. Results: Group A, which received one long arch segment, showed a Km decrease of 4.42D (8.7%) and a corneal astigmatism reduction of 2.43D (40.4%). Group B, where the eyes acquired two traditional arch segments, showed an average Km decrease of 2.66D (5.1%) and corneal astigmatism reduction of 2.11D (34.8%). The mean keratometry (Km) reduction obtained was statistically significant (p≤0.05) when comparing both groups (A and B). The mean corneal astigmatism reduction was not statistically significant (p≤0.05) when comparing both groups (A and B). Conclusions: One long-arch segment has been demonstrated to have a greater capacity to reduce corneal curvature when compared to the use of two traditional-sized arch segments. No significant differences were found regarding the reduction of corneal astigmatism after comparing the results obtained in both groups.

ABSTRACT

The use of implantable cardioverter defibrillators (ICDs) in young women has been increasing in recent years owing to greater awareness about inherited cardiac conditions that increase the risk of sudden death. Traditional placement of ICDs in the infraclavicular region among young women often leads to visible scars, a constant prominence that causes irritation from purse or bra straps and can result in body image concerns and device-related emotional distress. In this case series, two women with long QT syndrome required placement of ICDs for prevention of sudden cardiac death. Submammary placement of ICDs was performed in collaboration with electrophysiologists. We describe our local experience and technique in submammary placement of ICDs as well as the challenges faced.

ABSTRACT

Resumen La fundoplicatura de Nissen laparoscópica (FNL) es el gold standard del tratamiento quirúrgico de pacientes con reflujo gastroesofágico patológico (RGE), con perfil de seguridad y resultados a largo plazo satisfactorios en un 80%. En la última década, se ha propuesto el uso de un dispositivo de potenciación del esfínter esofágico inferior (MSA) comercializado como LINX® (de Ethicon, Johnson & Johnson), como alternativa a la cirugía antirreflujo. El dispositivo consiste en una cadena expansible de cuentas de titanio con un núcleo magnético diseñadas para aumentar el tono del esfínter esofágico inferior (EEI) y evitar su relajación inadecuada. Los resultados preliminares han sido alentadores, sin embargo, no está exento de complicaciones. Las indicaciones más aceptadas son: RGE con motilidad esofágica normal y sin esofagitis erosiva, hernia hiatal < 3 cm, IMC <35 kg/m2 y pacientes sin cirugías gastroesofágicas previas. Se instala por vía laparoscópica. Los efectos adversos más importantes son: disfagia con necesidad de dilataciones endoscópicas, y, retiro del dispositivo, entre 1% y 7% a los 2,5 años. La mayoría de los estudios tienen limitaciones metodológicas, conflictos de interés, falta de resultados objetivos y seguimientos a largo plazo, impidiendo llegar a conclusiones extrapolables respecto a la eficacia del MSA.


Laparoscopic Nissen Fundoplication (LNF) is the gold standard of surgical treatment for patients with Gastroesophageal Reflux Disease (GER), with safety profile and long term results satisfactory in 80%. In the last decade, the use of a Lower Esophageal Sphincter Enhancement Device (LESD), marketed as LINX® (from Ethicon, Johnson & Johnson), has been proposed as an alternative to Anti-Reflux Surgery. The device consists of an expandable chain of titanium beads with a magnetic core designed to increase the tone of the lower esophageal sphincter (LES) and prevent its improper relaxation. Preliminary results have been encouraging; however, it is not without complications. The most accepted indications are: GER with normal esophageal motility and without erosive esophagitis, hiatal hernia < 3 cm, BMI <35 kg/m2, and patients without previous gastroesophageal surgeries. It is installed by laparoscopy. The most important adverse effects are: dysphagia with the need for endoscopic dilations, and, removal of the device, between 1 and 7% at 2.5 years. Most of the studies have methodological limitations, conflicts of interest, lack of objective results and long-term follow-up, preventing the reaching of extrapolable conclusions regarding the efficacy of MSA.

ABSTRACT

Resumen Objetivo Comunicar la experiencia en el tratamiento de pectus excavatum en el Instituto Nacional del Tórax. Material y Método: Estudio descriptivo con seguimiento. Se recolectaron datos de las variables de interés, mediante la revisión de fichas clínicas. Se incluyeron pacientes operados entre marzo de 2007 y abril de 2018. Resultados Se incluyeron 86 pacientes operados con técnica mínimamente invasiva en el período descrito. De ellos, 74 pacientes de sexo masculino. El promedio de edad al momento de la cirugía fue de 17,8 años. El principal motivo de consulta fue por desmedro estético que correspondió al 41,8% de los pacientes. Salvo en 1 paciente, en todo el resto se ocupó una sola barra. En nuestra serie hubo 12 pacientes que presentaron alguna complicación operatoria y 1 paciente fallecido. Hasta el cierre del seguimiento se retiraron 61 barras, 2 de ellas previo al período estipulado de tratamiento, por morbilidad. Hay 20 barras in situ y 4 pacientes de los cuales no se tiene registro por abandono de controles. Discusión El pectus excavatum es la más frecuente de las deformidades de la pared torácica, es 4 a 6 veces más frecuente en hombres que en mujeres. En general los pacientes son asintomáticos, aunque algunos pueden presentar síntomas cardiopulmonares. La reparación con cirugía mínimamente invasiva con técnica de Nuss aparece hoy en día como el gold standard de manejo. Conclusión El manejo de los pacientes con pectus excavatum en nuestra Institución se asemeja a lo reportado en la literatura internacional. Nuestros esfuerzos deben apuntar a disminuir la morbimortalidad asociada.


Aim To communicate the experience in the treatment of pectus excavatum in the National Institute of Thorax. Materials and Method: Descriptive study with follow-up. Data of variables of interest were collected through the review of clinical records. Patients operated between March 2007 and April 2018 were included. Results 86 patients operated with the Nuss technique were included in the period described. Of them, 74 male patients. The average age at the time of surgery was 17.8 years. The main reason for consultation was due to cosmetic detriment that corresponded to 41.8% of the patients. Except in 1 patient, in all the rest a single bar was occupied. In our series, there were 12 patients who presented some operative complication and 1 patient died. Up to the end of the follow-up, 61 bars were removed, 2 of them in non-scheduled surgery. There are 20 bars in situ and 4 patients of which there is no registration due to abandonment of controls. Discussion Pectus excavatum is the most frequent of the deformities of the chest wall, it is 4 to 6 times more frequent in men than in women. In general, patients are asymptomatic, although some may have cardiopulmonary symptoms. The repair with minimally invasive surgery with Nuss technique appears today as the goldstandard of management. Conclusion The management of patients with pectus excavatum in our Institution is similar to that reported in the international literature. Our efforts should aim to reduce the associated morbidity and mortality.

ABSTRACT

ABSTRACT Purpose: This report addresses refractive, topographic, visual acuity, and optical coherence tomography outcomes 12 months after femtosecond, laser-assisted insertion of Ferrara intrastromal corneal ring segments in keratoconic eyes at a depth of 60%. Methods: Interventional, prospective, non-comparative case series. We performed femtosecond, laser-assisted insertion of Ferrara intrastromal corneal ring segments in 15 keratoconic eyes. We included patients with documented keratoconus who voluntarily signed informed consents if they had best spectacle-corrected visual acuity ≥0.30 logMAR and corneal thickness ≥400 μm. We excluded patients with previous ocular surgery or corneal curvatures >65 diopters (D). Our main outcome measures were best spectacle-corrected visual acuity and corneal topographic parameters (flattest, steepest and average keratometry [K]), evaluated at baseline and at 1-,3-,6-, and 12-month follow-ups. Results: The mean ± standard deviation baseline uncorrected visual acuity and best spectacle-corrected visual acuity were 1.03 ± 0.46 and 0.42 ± 0.13, respectively; the 12-month mean standard deviation uncorrected visual acuity and best spectacle-corrected visual acuity were 0.72 ± 0.37 and 0.31 ± 0.16, respectively, without significant differences (p=0.05 for both). The mean best spectacle-corrected visual acuity improvements were statistically significant after 3- (p=0.02) and after 6-months (p=0.02). The mean baseline flattest (K1), steepest (K2), and overall keratometries (mean power) were 48.35 ± 3.65 D, 53.67 ± 3.38 D, and 50.84 ± 3.36 D, respectively. The 12-month mean ± standard deviations for flattest-K1, steepest-K2, and overall K were 46.53 ± 3.70 D, 49.83 ± 3.50 D, and 48.12 ± 3.49 D respectively, with statistically significant differences for all three topographic parameters (p=0.01). Conclusions: Ferrara intrastromal corneal ring segment insertions at a depth of 60% yield satisfactory visual, refractive, and keratometric results in keratoconic eyes.


RESUMO Objetivos: Este estudo aborda os resultados refrativos, topográficos, acuidade visual e tomografia de coerência óptica, 12 meses após a inserção do segmento de Anel de Ferrara em túnel corneano a 60% de profundidade com o laser de femtosegundo, em pacientes com ceratocone. Métodos: Série de casos não comparativos, prospectivos e intervencionistas. Realizamos a inserção do Anel de Ferrara através de incisão com o laser de femtosegundo em 15 olhos ceratocônicos. Foram incluídos pacientes com ceratocone documentado que voluntariamente assinaram consentimentos informados que tivessem melhor acuidade visual corrigida ≥0.30 tabela logMAR, espessura corneana ≥400µm. Foram excluídos pacientes com cirurgia ocular prévia ou curvatura corneana > 65 dioptrias (D). As principais variáveis medidas foram acuidade visual corrigida e os parâmetros topográficos da córnea (ceratometria mais plana (K1), mais curva (K2) e ceratometria média (K médio), avaliadas no pré-operatório e com 1, 3, 6 e 12 meses de seguimento. Resultados: A média ± desvio padrão da acuidade visual sem correção e acuidade visual corrigida foi 1.03 ± 0.46 e 0.42 ± 0.13, respectivamente; o desvio padrão médio de 12 meses, a acuidade visual sem correção e acuidade visual corrigida foram de 0.72 ± 0.37 e 0.31 ± 0.16, respectivamente, sem diferenças significativas (p=0,05 para ambos). A melhora da acuidade visual corrigida foi estatisticamente significante após 3 meses (p=0,02), e após 6 meses (p=0,02). Os valores médios da linha de base K1, K2, e média (K médio) foram 48,35 ± 3,65D, 53,67 ± 3,38D, e 50,84 ± 3,36D, respectivamente. A média de 12 meses ± desvio padrão para K1, K2, e K médio foi 46,53 ± 3,70D, 49,83 ± 3,50 D, e 48,12 ± 3,49D respectivamente, com diferença estatisticamente significativas para todos os 3 parâmetros topográficos (p=0,01). Conclusões: A inserção do Anel de Ferrara a uma profundidade de 60% no estroma corneano produz resultados visuais, refracionais e ceratométricos satisfatórios em olhos com ceratocone.

ABSTRACT

Abstract Background: Considering the potential deleterious effects of right ventricular (RV) pacing, the hypothesis of this study is that isolated left ventricular (LV) pacing through the coronary sinus is safe and may provide better clinical and echocardiographic benefits to patients with bradyarrhythmias and normal ventricular function requiring heart rate correction alone. Objective: To assess the safety, efficacy, and effects of LV pacing using an active-fixation coronary sinus lead in comparison with RV pacing, in patients eligible for conventional pacemaker (PM) implantation. Methods: Randomized, controlled, and single-blinded clinical trial in adult patients submitted to PM implantation due to bradyarrhythmias and systolic ventricular function ≥ 0.40. Randomization (RV vs. LV) occurred before PM implantation. The main results of the study were procedural success, safety, and efficacy. Secondary results were clinical and echocardiographic changes. Chi-squared test, Fisher's exact test and Student's t-test were used, considering a significance level of 5%. Results: From June 2012 to January 2014, 91 patients were included, 36 in the RV Group and 55 in the LV Group. Baseline characteristics of patients in both groups were similar. PM implantation was performed successfully and without any complications in all patients in the RV group. Of the 55 patients initially allocated into the LV group, active-fixation coronary sinus lead implantation was not possible in 20 (36.4%) patients. The most frequent complication was phrenic nerve stimulation, detected in 9 (25.7%) patients in the LV group. During the follow-up period, there were no hospitalizations due to heart failure. Reductions of more than 10% in left ventricular ejection fraction were observed in 23.5% of patients in the RV group and 20.6% of those in the LV group (p = 0.767). Tissue Doppler analysis showed that 91.2% of subjects in the RV group and 68.8% of those in the LV group had interventricular dyssynchrony (p = 0.022). Conclusion: The procedural success rate of LV implant was low, and the safety of the procedure was influenced mainly by the high rate of phrenic nerve stimulation in the postoperative period.


Resumo Fundamento: Considerando-se os potenciais efeitos deletérios da estimulação do ventrículo direito (VD), a hipótese desse estudo é que a estimulação unifocal ventricular esquerda pelo seio coronário é segura e pode proporcionar melhores benefícios clínicos e ecocardiográficos aos pacientes com bradiarritmias que apresentam função ventricular normal, necessitando apenas da correção da frequência cardíaca. Objetivos: Avaliar a segurança, a eficácia e os efeitos da estimulação do ventrículo esquerdo (VE), utilizando um cabo-eletrodo com fixação ativa, em comparação à estimulação do VD. Métodos: Estudo clínico, randomizado, simples-cego em pacientes adultos com indicação de marca-passo (MP) devido a bradiarritmias e função ventricular sistólica ≥ 0,40. A randomização aleatória (VD vs VE) ocorreu antes do procedimento. Os desfechos primários do estudo foram: o sucesso, a segurança e a eficácia do procedimento proposto. Os desfechos secundários foram: a evolução clínica e alterações ecocardiográficas. Empregou-se os testes Qui-quadrado, Exato de Fisher e t de Student, com nível de significância de 5%. Resultados: De junho de 2012 a janeiro de 2014 foram incluídos 91 pacientes, sendo 36 no grupo VD e 55 no grupo VE. As características basais dos pacientes dos dois grupos foram similares. O implante de MP foi realizado com sucesso e sem nenhuma intercorrência em todos os pacientes do grupo VD. Dos 55 pacientes inicialmente alocados para o grupo VE, o implante do cabo-eletrodo em veias coronárias não foi possível em 20 (36,4%) pacientes. Dentre os 35 pacientes que permaneceram com o cabo-eletrodo no VE, a estimulação frênica foi a complicação mais frequente e foi detectada em 9 (25,7%) pacientes. Na fase de seguimento clínico, não houve hospitalizações por insuficiência cardíaca. Reduções superiores a 10% na fração de ejeção do VE foram observadas em 23,5% dos pacientes do grupo VD e em 20,6% dos pacientes do grupo VE (p = 0,767). A análise feita pelo Doppler tecidual mostrou que 91,2% dos indivíduos do grupo VD e 68,8% dos do grupo VE apresentaram dissincronia interventricular (p = 0,022). Conclusões: A taxa de sucesso do implante no VE foi baixa e a segurança do procedimento foi influenciada, principalmente, pela alta taxa de estimulação frênica no pós-operatório.

ABSTRACT

Resumen El tratamiento de la falla cardiaca terminal avanzada ha sido el trasplante de corazón, sin embargo, hay limitantes en cuanto a las características del receptor y disponibilidad de donadores, por lo que se ha utilizado alternativamente el soporte ventricular como tratamiento de destino. Se describe a una paciente con falla cardiaca terminal por cardiomiopatía isquémica en quien se implantó exitosamente un sistema de soporte ventricular izquierdo y a ocho meses del procedimiento se encontraba en clase funcional I, sin complicaciones.


Abstract The treatment of refractory terminal heart failure has been heart transplantation. However, there are limitations with regard to clinical conditions of the recipient and availability of donors, and ventricular support has therefore been alternatively used as destination therapy. We describe the case is of a female patient with ischemic cardiomyopathy-associated heart failure who had a left ventricular assist device successfully implanted and at eight months of the procedure was at functional class I, with no complications.

ABSTRACT

Abstract Introduction Bone anchored hearing aids (BAHA) represent a useful surgical option for patients with single sided deafness. Objectives To compare multiple techniques for BAHA implantation regarding postoperative complications, operative time, and duration between the surgery and the first use of the BAHA. Methods A retrospective study was conducted of all patients receiving implantation of a BAHA from August of 2008 to October of 2014. Data collected included: patient age, gender, side operated, abutment length, operative time, duration until first use of the BAHA, operative technique, and postoperative complications. The statistical analysis was performed using analysis of variance (ANOVA), Tukey pairwise comparison, chi-square, and paired t-test. Statistical significance was determined using a level of p< 0.05. Results A total of 88 patients (43 female and 45 male) were included in the data analysis. A total of 80 complications were documented, and these complications were classified according to the Holgers criteria. A significant difference in the total postoperative complications existed between the six techniques used (ANOVA; p< 0.01). In addition, there was also a significant difference among the six techniques employed regarding the operative time (ANOVA; p< 0.01). The average time duration until fitting of the BAHA processor among the various techniques trended toward but did not reach statistical significance (ANOVA; p= 0.16). Conclusions Significant differences in the operative outcomes exist among the various techniques for BAHA implantation. Based on the statistical analysis of our data, the BAHA Attract system (Cochlear Ltd., Sidney, Australia) requires greater operative time, but it is associated with less postoperative complications than percutaneous techniques and its processor may be fitted significantly sooner.

ABSTRACT

ABSTRACT Purpose: The objective of the present study is to test the efficiency and practicality of a new artificial sphincter "BR - SL - AS - 904" in the control of urinary incontinence in post - PR patients and to evaluate their complications. Patients and Methods: Fifteen patients with incontinence after one year of radical prostatectomy were included prospectively. All patients underwent artificial urethral sphincter (AUS) implant "BR - SL - AS - 904" according to established technique. Independent variables such as free urinary flow, PAD weight test, ICIQ - SF score and urinary symptoms through the IPSS score were compared in different follow-up moments. Results: Patients submitted to AUS implantation did not present trans - operative or post - operative complications related to the surgical act such as: infection, hematoma, erosion or urinary retention. Device was inert to the body during the follow-up, showing an excellent adaptation of the patients, besides the easy handling. The mean age was 68.20 years 40% of the patients had systemic arterial hypertension, 6.7% diabetes mellitus, 6.7% were hypertensive and diabetic, 13.4% were hypertensive, had diabetes and hypercholesterolemia and 26.7% patients had no comorbidities. It was evidenced that the urinary flow peak during the follow-up remained stable. Decreased averages and median PAD weight test were 135.19 to 75.72 and 106.00 to 23.50, respectively. The IPSS score decreased and the quality of life increased (12.33 to 3.40 and 2.50 to 3.20 respectively). The ICQF - SF questionnaire score also showed a decrease, ranging from 16, 71 to 7.33. Conclusion: The artificial sphincter implant "BR - SL - AS 904" was reproducible, safe and effective in the control of urinary incontinence in post - PR patients.

ABSTRACT

Resumo Objetivo: Relatar perfil clínico epidemiológico de pacientes que apresentaram o pico hipertensivo após o IVA e apontar possíveis fatores de risco associados. Métodos: Estudo retrospectivo, observacional e descritivo (revisão de prontuário de pacientes assistidos no IBOPC) de 2014 a 2016. Resultados: Foram analisados 40 pacientes com glaucoma submetidos à implante de válvula de Ahmed. O diagnóstico pré-operatório mais comum foi glaucoma secundário, sendo a indicação pós-transplante penetrante de córnea a mais frequente. 95% das cirurgias foi de implante de tubo isolado. 56% dos pacientes tinham cirurgia anti- glaucomatosa prévia. 46% necessitaram de procedimento cirúrgico posterior para manejo de complicações pós-operatórias, sendo que a mais frequente foi atalamia (9,7%). PIO média no pré-operatório = 28,6 ± 12.20mmHg, com uso de 3,41 medicações. Com 3 semanas a PIO média aumentou para 16mmHg, com uso de 0,42 medicações. Após 3 meses de cirurgia a PIO média estava em 16.5mmHg, com uso de 1,86 de medicações. Após 6 meses de seguimento a PIO média reduziu (16,4 ± 6.74mmHg), com 2,23 ± 1.45 medicações. A média da AV (Snellen) foi de 20/100p no pré-operatório e de 20/200 após 6° mês de cirurgia. Catorze pacientes preencheram os critérios para a FH, destes 6 obtiveram resolução da FH. Dos pacientes que desenvolveram a FH, 78,4% iniciaram a elevação da PIO entre a 2ª e 4ª semana de pós-operatório. Seis (14,6%) pacientes obtiveram sucesso cirúrgico completo, parcial em 36,6% e falência 31%. Conclusão: A fase hipertensiva pode ocorrer em parte dos pacientes após as semanas iniciais do procedimento cirúrgico. O conhecimento deste fenômeno, o preparo prévio do cirurgião, o acompanhamento regular do paciente e o controle da PIO com o uso de medicações são determinantes na resolução desta complicação.


Abstract Objective: To report the clinical epidemiological profile of patients who presented the hypertensive peak after VAT and to indicate possible associated risk factors. Methods: A retrospective, observational and descriptive study (review of medical records of patients assisted in the IBOPC) from 2014 to 2016. Results: We analyzed 40 patients with glaucoma submitted to Ahmed Glaucoma Valve implant. The most common preoperative diagnosis was secondary glaucoma, with the most frequent corneal penetrating post-transplant indication. 95% of the surgeries were of isolated tube implantation. 56% of patients had previous anti-glaucomatous surgery. 46% needed a posterior surgical procedure to manage postoperative complications, and the most frequent was atalamia (9.7%). IOP preoperatively = 28.6 ± 12.20mmHg, with use of 3.41 medications. At 3 weeks the mean IOP increased to 16mmHg, with use of 0.42 medications. After 3 months of surgery the mean IOP was 16.5mmHg, with use of 1.86 of medications. After 6 months of follow-up the mean IOP decreased (16.4 ± 6.74 mmHg), with 2.23 ± 1.45 medications. The mean of the AV (Snellen) was 20 / 100p in the preoperative period and 20/200 after the 6th month of surgery. Fourteen patients fulfilled the criteria for HP, of which 6 obtained HP resolution. Of the patients who developed HP, 78.4% started to elevate IOP between the 2nd and 4th postoperative week. Six (14.6%) patients had complete surgical success, partial in 36.6% and bankruptcy in 31%. Conclusion: The hypertensive phase may occur in part of the patients after the initial weeks of the surgical procedure. The knowledge of this phenomenon, the previous preparation of the surgeon, the regular monitoring of the patient and the control of IOP with the use of medications are determinant in the resolution of this complication.

ABSTRACT

ABSTRACT Purpose: To evaluate the outcomes of dermis-fat graft procedure for orbital volume replacement in anophthalmic socket. Methods: A retrospective chart review was performed studying all dermis-fat graft surgeries done at King Khlaed Eye Specialist Hospital in the last 10-year period. Sixty-two anophthalmic socket carriers underwent dermis-fat graft during the study period. Data were collected on characteristics of the patients, postoperative complications, cosmesis, and functional results such as the ability to hold an external prosthesis. Results: Mean age of the patients included in the study was 34.2 ± 9.7 years. There were 38.7% of patients with grade 3 anophthalmic socket, 64.5% of patients had an acquired anophthalmic socket, and dermis-fat graft was performed as a secondary procedure in 61.3% of patients. Postoperative complications included lagophthalmos (22.6%), graft necrosis (17.7%), pyogenic granuloma (12.9%), decreased graft size (12.9%), malpositioned lids (3.2%), and volume deficiency (3.2%). The prosthesis was held in place in 49 patients (79%) preoperatively and in 55 patients (88.7%) postoperatively. Conclusion: Dermis-fat graft is an excellent option for congenital or acquired as well as primary or secondary anophthalmic sockets, with or without contraction. The outcomes are favorable, and complications are rare.


RESUMO Objetivo: Avaliar os resultados obtidos com o uso do enxerto dermo-adiposo para reposição de volume em cavidade anoftálmica. Métodos: Estudo retrospectivo baseado em revisão de prontuários incluindo todas as cirurgias de enxerto dermo-adiposo realizadas nos últimos 10 anos no King Khaled Eye Specialist Hospital, Saudi Arabia. O enxerto dermo-adiposo foi realizado em 62 pacientes no periodo do estudo. Os dados analisados incluíram características dos pacientes, as complicações pós- operatórias e os resultados cosméticos e funcionais, tais como a habilidade de usar prótese externa. Resultados: A média de idade dos participantes foi de 34,2 ± 9,7 anos. Segundo a classificação das cavidades, 38,7% possuíam cavidade grau 3; 64,5% possuíam cavidade anoftálmica adquirida e o enxerto dermo-adiposo foi realizado como procedimento secundário em 61,3% dos pacientes. Após o procedimento 22,6% dos pacientes permaneceram com lagoftalmo, 17,7% tiveram necrose do enxerto, 12,9% desenvolveram granuloma piogênico, 12,9% tiveram redução do tamanho do enxerto, 3,2% permaneceram com as alterações no posicionamento palpebral e 3,2% continuaram com déficit de volume na órbita. Quarenta e nove pacientes (79%) eram capazes de usar prótese externa antes da cirurgia e depois do enxerto dermo-adiposo 55 (88,7%) puderam utilizar prótese externa. Conclusão: O enxerto dermo-adiposo é uma ótima opção para tratamento de cavidades anoftálmicas congênitas ou adquiridas, assim como realizado como procedimento primário ou secundário, em cavidades com ou sem contração tecidual. Os resultados são encorajadores e as complicações são pouco frequentes.

ABSTRACT

Abstract We present a case of a 12-year-old patient with advanced keratoconus in both eyes who received a two-staged treatment in the right eye (OD) to decrease keratoconus progression rate and rehabilitate patient's vision. At the initial clinical examination, visual acuity without correction in OD was count fingers; cycloplegic refraction was -22.00 - 7,50 x 100° = 20/400; corneal topography demonstrated a curvature of 64.28 x 105° / 55.38 x 15°; and tomography (WaveLight - Allegro Oculyzer) demonstrated a curvature of 68.1 x 114° / 63.3 x 163° Q = -2.67. Initially, the patient received an intrastromal ring segment (210 mm / 200 µm) slightly off center to avoid the thinnest part of the cornea. Six months later a phakic lens was implanted in the anterior chamber. At the follow-up visit 13 months after phakic lens implantation (19 months after ring implantation), visual acuity in OD was 20/20 without correction; cycloplegic refraction was -0.50 -0.75 x 180o = 20/20; and corneal topography showed keratometry of 63.22 x 44o / 61.10 x 134o. The results demonstrated that the associated procedures were successful in decreasing irregular astigmatism and markedly improving patient's uncorrected visual acuity in OD, postponing the need for corneal transplantation to a more suitable age, if required.


Resumo Apresentamos o caso de um paciente de 12 anos de idade com ceratocone avançado em ambos os olhos, que recebeu um tratamento em dois estágios no olho direito (OD) de modo a diminuir a taxa de progressão do ceratocone e reabilitar a visão do paciente. No exame clínico inicial, a acuidade visual sem correção no OD era contar dedos; refração sob cicloplegia era -22.00 - 7,50 x 100° = 20/400; a topografia demonstrou uma curvatura de 64,28 x 105° / 55,38 x 15°; e a tomografia (WaveLight - Allegro Oculyzer) demonstrou uma curvatura de 68,1 x 114° / 63,3 x 163° Q = -2,67. Inicialmente, o paciente recebeu um segmento de anel intraestromal (210 mm /200 µm) ligeiramente fora de centro de modo a evitar a porção mais fina da córnea. Seis meses mais tarde, uma lente fácica foi implantada na câmara anterior. No acompanhamento de 13 meses após a implantação da lente fácica (19 meses após a implantação do anel), OD apresentava uma acuidade visual de 20/20 sem correção; uma refração sob cicloplegia de -0,50 -0,75 x 180o = 20/20; e a topografia da córnea demonstrou ceratometria de 63,22 x 44° / 61,10 x 134°. Os resultados demonstraram que a associação de procedimentos foi bem sucedida na diminuição do astigmatismo irregular, com uma melhora significativa da acuidade visual sem correção no OD, adiando a necessidade de transplante de córnea para uma idade mais adequada, caso necessário.

ABSTRACT

ABSTRACT Objective: To evaluate urodynamic alterations after sub-urethral sling surgery (SSU) in patients with post-prostatectomy urinary incontinence (PPUI). Materials and Methods: We evaluated data of 22 patients submitted to radical prosta- tectomy (RP) or transurethral resection of prostate (TURP) that presented post-surgical urinary incontinence and were treated with SSU implant in a pilot study previously performed in our institution. Methods: Those patients with PPUI were evaluated by urodynamic exam (UD) before and after surgery, and the parameters were compared, including uroflow, cystometry and micturition study. Exclusion criteria included patients without pre-operatory urodynamic study, those with urethral stenosis, those not healed of prostate cancer, pa- tients without clinical conditions to be submitted to urodynamic study and those with severe neurological diseases or that refused to sign the consent form. Results were analyzed statistically by Fisher, Wilcoxon or Mann-Whitney tests. Results: During free uroflow, none parameters showed any statistical significant differ- ences. During cystometry, there were also no statistical differences and the same was observed at pressure versus flow study; the exception was at maximal flow detrusor pressure (PdetQmax), that was lower at post-operatory (p=0.028). In relation to the presence of urinary dysfunctions associated to PPUI, we observed a significant reduc- tion of detrusor overactivity (p=0.035) in relation to pre-operatory period. Conclusion: SSU surgery significantly reduced detrusor overactivity and PdetQMax; however, there were no alterations of other evaluated urodynamic parameters.

ABSTRACT

ABSTRACT Surgical correction is the most efficient treatment for stress urinary incontinence (SUI), and transobturator sling (TO) has optimal results. The high cost of commercially available sling kits makes it difficult the access in most Brazilian public health services. Hand-made polypropylene slings, on the other hand, have been previously reported. The aim of the present study was to compare the effectiveness and safety of commercial vs. hand-made polypropylene mesh slings. Data from 57 women who underwent consecutive TO sling surgery to treat SUI were pros- pectively collected between 2012 and 2014, and divided in two groups for further compa- rison. In Group-1, 31 women underwent surgery with commercial slings. In Group-2, 26 women underwent hand-made polypropylene slings. Women were compared according to epidemiological data, perioperative evaluation, quality of life, urodynamic study, cure and complication rates. Results were objectively (stress test with Valsalva maneuver, with at least 200mL vesical repletion) and subjectively evaluated by the Patient Global Impression of Improvement(PGI-I), Visual Analog Scale (VAS) and ICIQ-SF. Success was defined as PGI-I, VAS and negative stress test. Group-1 (n=31) and Group-2 (n=26) had a mean age of 60 vs. 58years (p=0.386). All de- mographic data were similar. The mean VLPP was 75.6cmH2O vs. 76.6cmH2O (p=0.88). The mean follow-up was 24.3 vs. 21.5months (p=0.96). Success rates were 74.2% vs. 80.2% (p=0.556), with ICIQ-SF variation of 12.6 vs.15.5 (p=0.139) and PGI-I of 71% vs. 80% (p=0.225). There was only one major complication (urethrovaginal fistula in Group-1). In conclusion, handmade and commercial slings have similar effectiveness and safety. The manufacture technique has important key-points stated in the present manuscript.

ABSTRACT

ABSTRACT Purpose: To evaluate the long-term outcomes of Boston type I keratoprosthesis (B-Kpro) in the management of patients with ocular burn injuries. Methods: This prospective study included all patients with ocular burns who underwent B-Kpro implantation at a tertiary eye care center between February 2008 and November 2015. Twelve patients (12 eyes) were enrolled. The procedures performed for managing ocular injury were identified, and information on ocular history, surgical procedures performed, and postoperative outcomes was collected. The main outcome measures were visual acuity, prosthesis retention, postoperative complications, and required surgical procedures. Results: Twelve eyes from 12 patients met the inclusion criteria for B-Kpro implantation, including nine eyes with alkali burns and three eyes with thermal burns. A total of 13 B-Kpro devices were implanted in the 12 eyes. The mean follow-up period was 60.8 months (range, 13-91 months). Preoperative best-corrected visual acuity ranged from counting fingers to light perception. Postoperative best-corrected visual acuity was better than 20/200 in 83.3%, 66.6%, and 57.1% of patients at 12, 48, and 60 months, respectively. The initial keratoprosthesis was retained in 10 (83.3%) eyes and was successfully replaced in one eye. The major cause of worsening of initial visual acuity was advanced glaucoma (four of 12 eyes). Conclusion: The anatomical and functional results support the use of B-Kpro for managing bilateral limbal stem cell deficiency secondary to ocular burns. However, glaucoma should be carefully evaluated, as it is a continuous threat that may result in irreversible visual loss in this population.


RESUMO Objetivo: Avaliar os resultados em longo prazo do implante da ceratoprótese de Boston tipo 1 (B-Kpro) no tratamento de pacientes vítima de queimadura ocular. Métodos: Trata-se de um estudo prospectivo envolvendo todos os casos de implante de B-Kpro 1 para queimadura ocular em um centro de oftalmologia terciário durante o período de fevereiro/2008 e novembro/2015. Doze pacientes (doze olhos) foram incluídos no estudo. Os procedimentos realizados para o manejo da queimadura ocular foram identificados, e os dados foram coletados com relação à história oftalmológica do paciente, procedimentos cirúrgicos realizados, e resultados pós-operatórios. Os principais parâmetros avaliados foram acuidade visual, retenção da prótese, complicações pós-ope ratórias e intervenções cirúrgicas necessárias. Resultados: Doze pacientes preencheram os critérios de inclusão para implante da B-Kpro, incluindo 09 olhos vítimas de queimadura por álcali e 03 olhos pós queimadura térmica. Um total de 13 B-Kpro tipo 1 foram implantadas em 12 olhos de 12 pacientes. O tempo de seguimento médio foi de 60,8 meses (variando, 13-91 meses). Melhor acuidade visual corrigida pré-operatória variou de conta dedos à percepção luminosa. Melhor acuidade visual corrigida pós-operatória foi melhor que 20/200 em 83,3%, 66,6% e 57,1% dos pacientes em 12 meses, 48 meses e 60 meses, respectivamente. A ceratoprótese inicialmente implantada permaneceu retida em 10 (83,3%) dos olhos e foi re-implantada com sucesso em um olho. A principal causa de piora da acuidade visual inicialmente atingida foi glaucoma avançado (4 de 12 olhos). Conclusão: Os resultados anatômicos e funcionais reportados neste estudo dão suporte ao uso da B-Kpro para o tratamento da deficiência límbica bilateral secundária a queimadura ocular. Glaucoma é o principal fator limitante e pode causar perda visual irreversível nesses pacientes.

ABSTRACT

Abstract Introduction: The bone-anchored hearing aid is an effective form of auditory rehabilitation. Due to the nature of the implant, the most common complications are skin related. A number of alternative surgical implantation techniques have been used to reduce the frequency and severity of skin complications, including the U-shaped graft and the linear incision. Objective: To assess skin complications and their association with surgical technique, quality of life, and audiological benefit in patients with bone-anchored hearing aids. Methods: This was a retrospective study conducted in a tertiary referral center in Bogotá, Colombia. Patients who had been fitted with a bone-anchored hearing aid implant (unilaterally or bilaterally) for at least 6 months were included in the study. The Holgers classification was used to classify skin complications (Grade 0 = none; Grade 1 = erythema; Grade 2 = erythema and discharge; Grade 3 = granulation tissue; and Grade 4 = inflammation/infection resulting in the removal of the abutment). The Glasgow Benefit Inventory questionnaire was used to determine quality of life, and the Abbreviated Profile of Hearing Aid Benefit questionnaire was used to determine the subjective audiological benefit. Results: A total of 37 patients were included in the study (30 with unilateral implants and 7 with bilateral implant). Of the 44 implants evaluated, 31 (70.3%) were associated with skin complications (7 [15.9%] Grade 1; 4 [9.1%] Grade 2; 15 [34.1%] Grade 3, 5 [11.4%] Grade 4). The U-shaped graft was statistically associated with major complications (Grades 3 and 4) compared with the linear incision technique (p = 0.045). No statistically significant differences were found between Abbreviated Profile of Hearing Aid Benefit scores and severity of complications. Similarly, no differences were found between Glasgow Benefit Inventory physical health questions and skin complications. Conclusion: Despite the high frequency, skin complications did not seem to affect quality of life or subjective audiological benefits of patients with bone-anchored hearing aids.


Resumo Introdução: A prótese auditiva óssea (BAHA, do inglês Bone-Anchored Hearing Aid) é uma forma eficaz de reabilitação auditiva. Devido à natureza do implante, as complicações mais comuns são relacionadas à pele. Várias técnicas opcionais de implantação cirúrgica têm sido usadas para reduzir a frequência e a gravidade das complicações cutâneas, inclusive o enxerto em forma de U e a incisão linear. Objetivo: Avaliar as complicações cutâneas e sua associação com a técnica cirúrgica, qualidade de vida e benefício audiológico em pacientes com BAHAs. Método: Estudo retrospectivo feito em um centro terciário de referência em Bogotá, Colômbia. Os pacientes que receberam um implante de BAHA (unilateral ou bilateralmente) durante pelo menos seis meses foram incluídos no estudo. A classificação de Holgers foi usada para classificar as complicações cutâneas (Grau 0 = nenhuma, Grau 1 = eritema, Grau 2 = eritema e secreção, Grau 3 = tecido de granulação e Grau 4 = inflamação/infecção, resultou na remoção da estrutura de apoio). O questionário Glasgow Benefit Inventory (GBI) foi usado para determinar a qualidade de vida e o questionário Abbreviated Profile of Hearing Aid Benefit (APHAB) foi usado para determinar o benefício audiológico subjetivo. Resultados: Foram incluídos 37 pacientes (30 com implantes unilaterais e sete com implantes bilaterais). Dos 44 implantes avaliados, 31 (70,3%) foram associados às complicações cutâneas (sete [15,9%] Grau 1; quatro [9,1%] Grau 2; 15 [34,1%] Grau 3 e cinco [11,4%] Grau 4). O enxerto em forma de U foi estatisticamente associado a complicações maiores (Graus 3 e 4) em comparação com a técnica de incisão linear (p = 0,045). Não foram encontradas diferenças estatisticamente significativas entre os escores APHAB e gravidade das complicações. Do mesmo modo, não foram encontradas diferenças entre as questões de saúde física pelo questionário GBI e complicações cutâneas. Conclusão: Apesar da alta frequência, as complicações cutâneas não parecem afetar a qualidade de vida ou os benefícios audiológicos subjetivos de pacientes com BAHAs.

ABSTRACT

ABSTRACT Purpose We present a novel AUS implantation technique using a single perineal incision for single device placement or in combination with an inflatable penile prosthesis (IPP). Urinary and sexual dysfunction following the management of prostate cancer has a significant impact on the quality of life of our patients. While there are marginal changes in the prosthetic devices, we strive to reduce post-operative morbidity while maximizing efficacy. Materials and Methods We retrospectively reviewed the outcomes of 6 patients who underwent single perineal incision placement of a virgin AUS in 2014, 3 with simultaneous IPP placement. In all cases, the pressure regulating balloons (PRB) were placed in a high sub-muscular ectopic position and the pumps were placed into a sub-dartos pouch through the perineal incision, which was also validated using a cadaveric model. Results The mean patient age was 61 (SD, 7.5 years) with mean body mass index of 31 (SD, 5.9). The average pre-operative pad usage was 7.7 (SD 1.63) pads per day. The mean follow-up was 13.9 months (SD 9.45). Four out of the six patients reported utilizing ≤1 pad daily at follow-up. The one patient who was not initially dry required downsizing of his cuff to 3.5cm; the remaining patient was lost to follow-up. There were no identifiable perioperative or post-operative complications. Conclusions We present our initial report of using a single perineal incision for AUS implantation with a validated sub-dartos pump location, which is safe and effective for implantation of an AUS as a single or double implantation in well-selected patients.

ABSTRACT

CONTEXTO: Estima-se a ocorrência de cerca de 10.810 novos casos por ano de neoplasias malignas do esôfago, sendo a maioria diagnosticado apenas em estágios avançados, com tratamento prioritariamente paliativo. A disfagia é o sintoma mais frequente e que mais compromete a qualidade de vida do paciente, impactando negativamente no desfecho dos tratamentos oncológicos e cirúrgicos que possam ser ministrados para esta condição. O tratamento disponível no SUS é a sonda nasoenteral para alimentar os pacientes. TECNOLOGIA: Implantação endoscópica da prótese esofageana metálica auto expansível (PEMAE). INDICAÇÃO: Alívio da disfagia nas obstruções malignas do esôfago e junção esofagogástrica. CARACTERIZAÇÃO DA TECNOLOGIA: A implantação endoscópica da prótese esofageana metálica auto expansível é um método comum para paliação dos cânceres esofágicos avançados, tendo a rápida resposta clínica e baixa incidência de recorrência da disfagia como principais vantagens. PERGUNTA: Para pacientes com câncer de esôfago avançado, a implantação endoscópica da prótese esofageana metálica auto expansível é a opção mais eficiente e segura para o alívio da disfagia em relação a outros métodos paliativos? EVIDÊNCIAS CIENTÍFICAS: Na busca de artigos que tivessem o alivio da disfagia como desfecho mensurado, primário ou secundário nas bases de dados, não foram encontrados estudos de comparação direta das PEMAE com a sonda nasoenteral, entretanto encontrou-se revisão sistemática (RS) comparando as PEMAE com todos os outros métodos de tratamento a fim de determinar sua eficácia e segurança. Neste estudo, as PEMAE demonstraram resultados significativamente melhores no controle da disfagia e menor taxa de recidiva do sintoma do que as próteses plásticas. A análise do tempo de hospitalização, mortalidade relacionada ao procedimento e eventos adversos maiores também se mostraram mais favoráveis no grupo PEMAE, com significância estatística. AVALIAÇÃO ECONÔMICA: Avaliação de custo-efetividade com horizonte temporal de 6 meses cujos eventos de saúde foram definidos com base na revisão sistemática da literatura e os custos foram estimados pela metodologia de microcusteio de acordo com os valores de compras públicas. A estratégia de implantação endoscópica da PEMAE apresentou um custo de R$6.888,96 com taxa de efetividade clínica de 0,91, e o custo do suporte nutricional com sonda e dieta enteral foi de R$22.564,78 com efetividade clínica de apenas 0,44 e uma RCEI de R$ -33.374,08 Na análise de sensibilidade, no pior cenário (50% dos pacientes utilizariam a PEMAE), a PEMAE demonstrou ser mais barata e mais efetiva do que a passagem da sonda. AVALIAÇÃO DE IMPACTO ORÇAMENTÁRIO: A quantidade de indivíduos com câncer esofágico (10.810 novos casos por ano) e os dados de mortalidade para câncer esôfago avançado (70%) foram estimados utilizando-se os dados do INCA em 2016. Dados de estudos nacionais foram utilizados para determinar a quantidade de pacientes com câncer esofágico que evoluem anualmente para condição avançada (75%), sendo 30% dos casos os candidatos ao tratamento paliativo por sonda nasoenteral ou PEMAE. O gasto orçamentário total em cinco anos calculado foi de R$ 109.456.481,25 e R$ 358.218.852,15 para a implantação endoscópica da prótese esofageana metálica auto expansível e suporte nutricional com passagem de sonda nasoenteral, respectivamente, com uma diferença de R$249.068.088,34, favorecendo a proposta de incorporação da tecnologia em demanda. CONSIDERAÇÕES: Os resultados da RS demonstraram a eficácia e segurança da implantação endoscópica da PEMAE para controle da disfagia em comparação com outros métodos. Na avaliação econômica, esse procedimento foi mais custo-efetivo do que a passagem da sonda nasoenteral. RECOMENDAÇÃO PRELIMINAR: Os membros do Plenário da CONITEC, em sua 61ª reunião ordinária, recomendaram que a matéria fosse enviada à Consulta Pública com manifestação preliminar favorável à incorporação. Considerou-se que o procedimento é substituto ao existente no SUS, apresenta uma técnica segura, é mais eficaz no controle e recidiva da disfagia, com elevado perfil de segurança e com menor custo. CONSULTA PÚBLICA: Foram recebidas duas contribuições no formulário de experiência ou opinião e uma técnico-científica, sendo todas da região sudeste, Estado de São Paulo e que concordaram totalmente com a recomendação inicial da CONITEC. As duas contribuições de experiências ou opinião foram de profissionais que relataram ter experiência com a tecnologia avaliada, sendo que um deles também relatou experiência profissional com outra tecnologia. Na 63ª reunião ordinária, após apreciação das contribuições encaminhadas pela consulta pública, o plenário da CONITEC entendeu que as argumentações apresentadas corroboram com a recomendação inicial. RECOMENDAÇÃO FINAL: Os membros da CONITEC presentes na 63ª reunião ordinária, no dia 01 de fevereiro de 2018, deliberaram, por unanimidade, por recomendar a incorporação no SUS do procedimento de implantação endoscópica da prótese esofageana metálica auto expansível para tratamento da disfagia decorrente dos tumores esofágicos avançados e obstrutivos. DECISÃO: Incorporar a implantação endoscópica da prótese esofageana metálica autoexpansível para tratamento da disfagia dos tumores esofágicos avançados e obstrutivos no âmbito do Sistema Único de Saúde SUS, dada pela Portaria nº 15, publicada no DOU nº 61, do dia 29 de março de 2018, seção 1, pág. 240.(AU)

ABSTRACT

ABSTRACT Objectives Report the long-term outcomes of the AMS 800 artificial sphincer (AS) for the treatment post-prostatectomy incontinence (PPI) in a single center in Brazil. Materials and Methods Clinical data from patients who underwent the procedure were retrieved from the medical records of individuals with more than 1 year of follow-up from May 2001 to January 2016. Continence status (number of pads that was used), complications (erosion or extrusion, urethral atrophy, and infection), malfunctions, and need for secondary implantation were evaluated. The relationship between complications and prior or subsequent radiation therapy (RT) was also examined. Results From May 2001 to January 2016, 121 consecutive patients underwent AS implantation for PPI at an oncological referral center in Brazil. At the last visit, the AS remained implanted in 106 patients (87.6%), who reported adequate continence status (maximum of 1 pad/day). Eight-two subjects (67.8%) claimed not to be using pads on a regular basis at the final visit (completely dry). Revision occurred in 24 patients (19.8%). Radiation therapy (RT) for prostate cancer following radical prostatectomy was used in 47 patients before or after AS placement. Twelve patients with a history of RT had urethral erosion compared with 3 men without RT (p=0.004). Conclusion Considering our outcomes, we conclude that AS implantation yields satisfactory results for the treatment of PPI and should remain the standard procedure for these patients. Radiation therapy is a risk factor for complication.

ABSTRACT

Resumen INTRODUCCIÓN: La derivación acuosa ha surgido como una técnica alternativa a la trabeculectomía, considerada la cirugía de elección en pacientes con glaucoma. Actualmente, se considera que la principal indicación de esta técnica es ante el fracaso de la trabeculectomía o en tipos de glaucoma que tienen alto riesgo de fracasar. La válvula Ahmed y el implante Baerveldt son las derivaciones acuosas más utilizadas. Sin embargo, no está claro cuáles son las diferencias entre estas dos alternativas. MÉTODOS: Para responder esta pregunta utilizamos Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud a nivel mundial, la cual es mantenida mediante búsquedas en múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, reanalizamos los datos de los estudios primarios, realizamos un metanálisis y preparamos una tabla de resumen de los resultados utilizando el método GRADE. RESULTADOS Y CONCLUSIONES: Identificamos cinco revisiones sistemáticas que en conjunto incluyeron 10 estudios primarios, de los cuales dos son ensayos aleatorizados. Concluimos que la válvula Ahmed probablemente logra una menor disminución de la presión intraocular; podría lograr un menor éxito calificado y probablemente necesita más reintervenciones que el implante Baerveldt. Respecto al perfil de seguridad, la válvula Ahmed no se presenta claramente superior ni inferior al implante Baerveldt.


Abstract INTRODUCTION: Aqueous shunt has emerged as an alternative technique to trabeculectomy, considered the standard for glaucoma surgery. Currently, it is mainly indicated after failure of trabeculectomy or in glaucoma with high risk of failure. The Ahmed valve and the Baerveldt implant are the most commonly used aqueous shunts. However, it is not clear whether there are differences between them. METHODS.: o answer this question we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. RESULTS AND CONCLUSIONS: We identified five systematic reviews including 10 studies overall, of which two were randomized trials. We concluded the Ahmed valve probably achieves a lower decrease in intraocular pressure, might lead to less qualified success and probably needs more reinterventions than the Baerveldt implant. Regarding safety profile, the Ahmed valve is not clearly superior or inferior to the Baerveldt implant.
