Escala predictiva de dehiscencia de la línea de sutura intestinal / A Predictive Scale for Dehiscence of the Intestinal Suture Line

Introducción: La dehiscencia de la línea de sutura es una de las complicaciones más frecuentes en la cirugía intestinal. Objetivo: Diseñar una escala predictiva para estimar de forma individual la probabilidad de dehiscencia de la línea de sutura intestinal. Métodos: Se realizó un estudio, analítico, de cohorte con recogida retrospectiva de datos en el sexenio 2014-2019 en el hospital "Celia Sánchez Manduley". La muestra fue de 437 pacientes y se usó la variable dependiente: dehiscencia de la línea de sutura intestinal y variables independientes: edad, sexo, comorbilidad, hemoglobina, hipoalbuminemia, neoplasia de colon, riesgo anestésico, entre otras. Resultados: En el análisis multivariado se obtuvo un modelo ajustado con las variables: edad mayor de 70 años (p = 0,002), hipoalbuminemia (p = 0,014), anastomosis enterocólica (p = 0,018), cirugía urgente (p = 0,001) e íleo paralítico prolongado (p < 0,001). La escala predictiva fue derivada del modelo estadístico ajustado y clasificado en 3 grupos de riesgo la probabilidad de dehiscencia de la línea de sutura intestinal: bajo (menor de 2 puntos), moderado (entre 3 y 5 puntos) y elevado (mayor de 6 puntos). Presentó una sensibilidad de 89,6 por ciento, especificidad de 89,1 por ciento, porciento predictivo global de 89,2 por ciento, valor predictivo positivo de 66,1 por ciento y valor predictivo negativo de 97,2 por ciento. Tuvo una excelente calibración y un elevado poder discriminativo. Conclusión: Se obtuvo una escala predictiva para estimar de forma individual la probabilidad de dehiscencia de la línea de sutura intestinal(AU)

ABSTRACT Introduction: The suture line dehiscence is one of the most frequent complications in intestinal surgery. Objective: To design a predictive scale for estimating individual probability of suture line dehiscence. Methods: An analytical cohort study, which involved retrospective data collection, was carried out, in the six-year period of 2014-2019, at Celia Sánchez Manduley Hospital. The sample consisted of 437 patients. Dehiscence of the intestinal suture line was used as a dependent variable, while age, sex, comorbidity, hemoglobin, hypoalbuminemia, colon neoplasia, anesthetic risk, among others, were used as independent variables. Results: Through multivariate analysis, an adjusted model was obtained, with the following results for the variables: age over 70 years (P=0.002), hypoalbuminemia (P=0.014), enterocolic anastomosis (P=0.018), urgent surgery (P=0.001), and ileus prolonged paralytic (P < 0.001). The predictive scale was derived from the adjusted statistical model and, based on the probability of dehiscence of the intestinal suture line, classified into three risk groups: low (less than two points), moderate (between 3-5 points) and high (more than six points). It presented a sensitivity of 89.6 percent, a specificity of 89.1 percent, a global predictive percentage of 89.2 percent, a positive predictive value of 66.1 percent, and a negative predictive value of 97.2 percent. It had an excellent calibration and a high discriminative power. Conclusion: A predictive scale was obtained for estimating the individual probability of dehiscence of the intestinal suture line(AU)

A simple modification of the conventional figure-of-eight sternal closure technique

Abstract Objective: To describe a new technique of sternal closure, modified from the conventional figure-of-eight approach, which can provide a secure closure and prevent sternal complications. Methods: The modified technique is based on the intercalation of the caudal portion of each steel wire passed along the sternum. This is a retrospective analysis of patients operated with this modified technique at our institution between January 2014 and December 2016. Results: One hundred and forty-three patients underwent sternal closure with the modified technique. In-hospital mortality rate was 1.4% (n=2). No sternal instability was observed at 30 days postoperatively. Two patients developed mediastinitis that required extraction of the wires. Conclusion: Short-term results have shown that the modified sternal closure technique can be used safely and effectively, with complications rates being consistent with worldwide experience.

Effects on ocular discomfort and tear film dynamics of suturing 23-gauge pars plana vitrectomies / Efeito da sutura da vitrectomia via pars plana de calibre 23 no desconforto ocular e na dinâmica do filme lacrimal

ABSTRACT Purpose: To evaluate the effects of suturing 23-gauge pars plana vitrectomies on ocular discomfort and tear film dynamics. Methods: This retrospective chart review involved data from 50 procedures in 50 patients who underwent 23-gauge pars plana vitrectomy from January to November 2016. We divided the eyes into two groups according to the presence or absence of sutures; 35 eyes underwent sutureless vitrectomies (Group 1), and 15 eyes underwent vitrectomy with at least one sclerotomy suture site (Group 2). In each group, we assessed objective variables including tear film break-up time, Schirmer test I, corneal surface grading with Oxford system, and a quantitative method evaluating subjective dry eye symptoms using ocular surface disease index questionnaires preoperatively 1 week, and 1 and 3 months after surgery. Results: The tear film break-up time showed a significant difference at the 3-months follow-up (p=0.026). The Schirmer test I and corneal surface staining score showed no statistically significant differences between two groups at any time after the operations. The ocular surface disease index score was significantly lower in Group 1 than in Group 2 at 1 week (p=0.032), 1 month (p=0.026), and 3 months (p=0.041) after the operation. Conclusion: Sclerotomy suturing caused ocular discomfort and had a negative effect on tear film dynamics during the late postoperative period. Sclerotomies without suturing seem to reduce the ocular surface changes.

RESUMO Objetivo: Avaliar os efeitos da sutura da vitrectomia via pars plana de 23-gauge sobre o desconforto ocular e a dinâmica do filme lacrimal. Métodos: Esta revisão retrospectiva de prontuários envolveu dados de 50 casos em 50 pacientes submetidos à vitrectomia via pars plana de 23-gauge, de janeiro a novembro de 2016. Dividimos os olhos em dois grupos de acordo com a presença ou ausência de suturas; 35 olhos foram submetidos à vitrectomia sem sutura (Grupo 1) e 15 olhos foram submetidos à vitrectomia com pelo menos um ponto de sutura no local da esclerotomia (Grupo 2). Em cada grupo, avaliamos variáveis objetivas incluindo tempo de ruptura do filme lacrimal, teste de Schirmer I, gradação da superfície corneana com o sistema Oxford e um método quantitativo avaliando sintomas subjetivos de olho seco usando questionários de índice de doença da superfície ocular nos períodos: 1 semana do pré-operatório, 1 mês e 3 meses após a cirurgia. Resultados: O tempo de ruptura do filme lacrimal apresentou diferença significativa no seguimento de 3 meses (p=0,026). O teste de Schirmer I e o escore da coloração da superfície da córnea não mostraram diferenças estatisticamente significativas entre os dois grupos em nenhum momento após as operações. O escore do índice de doença da superfície ocular foi significativamente menor no Grupo 1 em relação ao Grupo 2 no período de 1 semana (p=0,032), 1 mês (p=0,026) e 3 meses (p=0,041) após a cirurgia. Conclusão: A sutura da esclerotomia causou desconforto ocular e teve um efeito negativo na dinâmica do filme lacrimal durante o período pós-operatório. Esclerotomias sem sutura parecem reduzir as alterações da superfície ocular.

Resultados terapéuticos en pacientes con traumas de colon y recto tratados con sutura primaria o colostomía / Therapeutic Results in patients with Colon and Rectal Traumas Treated with Primary Suture or Colostomy

RESUMEN Introducción: El trauma de abdomen tiene alta incidencia y con frecuencia afecta el colon y el recto, se aboga por el tratamiento mediante sutura primaria. Objetivo: Identificar diferencias en las características clínico-quirúrgicas y resultados terapéuticos de pacientes con lesiones traumáticas de colon y recto, tratados con sutura primaria y técnicas derivativas. Método: Se realizó un estudio multicéntrico descriptivo ambispectivo para determinar características clínico-quirúrgicas y resultados terapéuticos en pacientes con lesiones traumáticas de colon y recto en los hospitales Carlos J. Finlay, Joaquín Albarrán, Calixto García y Enrique Cabrera de La Habana, en el periodo 2010-2015. El universo estuvo conformado por todos los pacientes intervenidos quirúrgicamente por trauma de colon y/o recto. Resultados: La colostomía fue el proceder más frecuente (53,1 por ciento). Los pacientes en edades medias de la vida (promedio: 43,5 años), sexo masculino (71,4 por ciento), evolución hasta el tratamiento quirúrgico menor de 12 horas (73,4 por ciento); causadas por empalamientos y otros (49 por ciento) y heridas con arma blanca (38,8 por ciento). La magnitud del daño de colon y recto fue baja, con mayor afectación de colon izquierdo. La frecuencia de complicaciones graves y mortalidad fue alta en la colostomía. Conclusiones: La sutura primaria muestra mejores resultados terapéuticos y debe ser la técnica de elección en las lesiones traumáticas de colon y recto intraperitoneal(AU)

ABSTRACT Introduction: Abdominal trauma presents high incidence and often affects the colon and rectum; primary suture is the preferred treatment. Objective: To identify differences between the clinical-surgical characteristics and the therapeutic outcomes in patients with traumatic lesions of the colon and rectum, treated with primary suture and derivative techniques. Method: A multicentric, descriptive and ambispective study was carried out to determine the clinical-surgical characteristics and the therapeutic outcomes in patients with traumatic colon and rectal lesions in Carlos J. Finlay, Joaquín Albarrán, Calixto García and Enrique Cabrera Hospitals in Havana, in the period from 2010 to 2015. The study population was made up of all patients surgically intervened for colon and/or rectal trauma. Results: The colostomy was the most frequent procedure (53.1 percent). Patients in middle ages of life (average: 43.5 years), male sex (71.4 percent), evolution to surgical treatment under 12 hours (73.4 percent); caused by impalement and others (49 percent) and cutting wounds (38.8 percent). The magnitude of colon and rectum damage was low, with greater involvement of the left colon. The frequency of serious complications and mortality was high in the colostomy. Conclusions: Primary suture shows better therapeutic results and should be the technique of choice in traumatic lesions of the intraperitoneal colon and rectum(AU)

Comparative study of polyglactin 910 and simple catgut in the formation of intraperitoneal adhesions

Abstract Purpose: To compare polyglactin 910 and simple catgut sutures for the incidence of intraperitoneal adhesions. Methods: Twenty female Wistar rats were placed into two groups. Group 1 received ischemic sutures and Group 2 received polyglactin 910. Five sutures inductive of adhesions in each rat were made. After 14 days, the rats were euthanized with an assessment of the presence of adhesions, the number of sutures involved and classification according to the Granat et al. scale described by Ozel et al17. Results: In total, 19 of the 20 rats presented adhesions, with nine from Group 1 and ten from Group 2. There was a smaller number of affected sutures in Group 1, while in Group 2 the majority of the sutures formed adhesions (p=0.0197). According to the Granat et al. scale, Group 1 predominately developed fine, filamentous adhesions or thickening in a restricted area. Group 2 mainly presented extensive, thick adhesions with the involvement of the viscera (p=0.0055). Conclusion: Polyglactin 910 sutures formed more adhesions that were more extensive and thicker than the simple catgut sutures.

Facial thread lifting with suture suspension / Rejuvenescimento facial com fios de sustentação

Abstract Introduction: The increased interest in minimally-invasive treatments, such as the thread lifting, with lower risk of complications, minimum length of time away from work and effectiveness in correcting ptosis and aging characteristics has led many specialists to adopt this technique, but many doubts about its safety and effectiveness still limit its overall use. Objective: To analyze data published in the literature on the durability of results, their effectiveness, safety, and risk of serious adverse events associated with procedures using several types of threading sutures. Methods: Literature review using the key words "thread lift", "barbed suture", "suture suspension" and "APTOS". Due to the scarcity of literature, recent reports of facial lifting using threads were also selected, complemented with bibliographical references. Result: The first outcomes of facial lifting with barbed sutures remain inconclusive. Adverse events may occur, although they are mostly minor, self-limiting, and short-lived. The data on the maximum effect of the correction, the durability of results, and the consequences of the long-term suture stay are yet to be clarified. Conclusion: Interest in thread lifting is currently high, but this review suggests that it should not yet be adopted as an alternative to rhytidectomy.

Resumo Introdução: O maior interesse por tratamentos minimamente invasivos, como os fios de sustentação, com menor risco de complicações, mínimo tempo de afastamento das atividades laborais e eficazes em corrigir a ptose e as rítides características do envelhecimento fez muitos especialistas adotarem essa técnica, porém muitas dúvidas sobre sua segurança e eficácia limitam sua adoção de forma geral. Objetivo: Analisar dados publicados na literatura sobre longevidade dos resultados, sua eficácia, segurança e seu risco de eventos adversos graves associados aos procedimentos com vários tipos de sutura. Método: Revisão de literatura com as palavras-chave thread lift, barbed suture, suture suspension e Aptos. Devido à escassez de literatura, foram também selecionados relatos recentes de rejuvenescimento facial com uso de fios, complementados com trabalhos das referências bibliográficas. Resultado: Os primeiros resultados da suspensão facial com fios com garras permanecem inconclusivos. Os eventos adversos podem ocorrer, embora em sua maioria sejam pequenos, autolimitados e de curta duração. Os dados sobre o efeito máximo da correção, a longevidade dos resultados e as consequências da permanência dos fios em longo prazo não são claros. Conclusão: O interesse pelo lifting com fios está em alta no momento, mas esta revisão sugere que ele não deve ser apresentado como opção a uma ritidoplastia.

Factores de riesgo relacionados a la falla de la sutura meniscal en niños y adolescentes / Risk factors related to meniscal suture failure in children and adolescents

Las lesiones meniscales en niños son cada día más frecuentes. La preservación meniscal es una prioridad en este grupo de pacientes, sin embargo, existen pocos artículos que muestran los resultados de suturas meniscales en niños. OBJETIVO: El objetivo de este estudio es identificar factores de riesgo de falla en pacientes sometidos a una sutura meniscal en niños menores de 18 años. MÉTODO: Estudio retrospectivo de 35 pacientes sometidos a una sutura meniscal, con una edad promedio de 16 años (13­18) y un seguimiento de 71 meses de media (16­115). Se evaluaron 6 variables: tipo, localización y tamaño de la lesión, edad, técnica quirúrgica y asociación a rotura de ligamento cruzado anterior (LCA). Los pacientes que presentaron falla de la sutura meniscal fueron identificados y sometidos a una regresión logística usando un modelo Stata V.14.0. RESULTADOS: 9 pacientes (24.3%) presentaron una falla en su cirugía durante el seguimiento. Lesiones iniciales mayores a 16 mm mostraron una tasa de re-rotura de un 73% independiente de la técnica quirúrgica. En lesiones menores a 16 mm, se obtuvo un 78% de reparaciones exitosas. No se encontró relación entre la re-rotura meniscal y lesión de LCA, tipo y localización de la lesión, técnica quirúrgica y edad de los pacientes. CONCLUSIÓN: Este estudio muestra que la reparación meniscal en niños tiene buenos resultados con una tasa de éxito promedio de un 75%. El riesgo de falla de sutura meniscal se correlacionó con el tamaño inicial de la lesión con un 73% de fallo en lesiones mayores a 16 mm independientemente del tipo de cirugía.

Meniscal tears are uncommon in the pediatric population, with an increasing number. Currently meniscal preservation is a priority when treating these injuries. However, only a few studies have reported the clinical outcomes of arthroscopic meniscal repair in children and its risk factors of failure. OBJECTIVE: Identify risk factors related to meniscal suture failure in patients under 18 years who underwent a meniscal repair. METHODS: Retrospective study of 35 patients with an average age of 16 years (13 - 18) who underwent arthroscopic meniscal repair with a mean follow up of 71.1 months (16­115). We evaluate 6 variables: type, location and size of meniscal tear, age, surgical technique and anterior cruciate ligament (ACL) association. Patients with re-rupture were identified and statistical analysis was performed through a logistic regression model using Stata V.14.0. RESULTS: 9 patients (24.3%) presented a suture failure during follow-up. Average time for re-rupture was 16 months (4­60 months). With an initial tear size of 16 mm or bigger, 73% of the meniscal repair will fail despite surgery technique. With an initial tear size smaller than 16 mm, 78% of will heal. No association was found between meniscal re-rupture and ACL rupture, type and location of tear, surgical technique and age. Conclusion: In our study meniscal repairs in pediatric population had good overall results with a global healing rate of 75.7%. The risk of suture failure was related to the initial size of meniscal tear: when meniscal tear is bigger than 16 mm, 73% of them will fail despite surgery.

Fixation of the short-term central venous catheter. A comparison of two techniques

Abstract Purpose: To compare the fixation of the central venous catheter (CVC) using two suture techniques. Methods: A clinical, analytical, interventional, longitudinal, prospective, controlled, single-blind and randomized study in adult, intensive care unit (ICU) patients. After admission and indication of CVC use, the patients were allocated to the Wing group (n = 35, catheter fixation with clamping wings and retainers) or Shoelace group (n = 35, catheter fixation using shoelace cross-tied sutures around the device). Displacement, kinking, fixation failure, hyperemia at the insertion site, purulent secretion, loss of the device, psychomotor agitation, mental confusion, and bacterial growth at the insertion site were evaluated. Results: Compared with the Wing group, the Shoelace group had a lower occurrence of catheter displacement (n=0 versus n =4; p = 0.04), kinking (n=0 versus n=8; p=0.001), and fixation failure (n=2 versus n=8; p=0.018). No significant difference was found in bacterial growth (n=20 versus n=14; p=0.267) between groups. Conclusion: The Shoelace fixation technique presented fewer adverse events than the Wing fixation technique.

Wound natural healing in treatment of tumor-like hypertrophic scar

Abstract: Background: Surgical sutures, wound tension, additional skin incisions and other factors may result in recurrence of tumor-like scar. Objective: To investigate the role of wound natural healing therapy in tumor-like hypertrophic scar. Methods: In this study, tumor-like hypertrophic scars of 47 cases were excised completely and the residual wounds were treated with natural healing. The short-term and long-term effects of treatment were evaluated. Results: All cases were successfully cured by natural healing therapy. The healing time of the maximum wound (80mm × 20mm) and the minimal wound (5mm× 5mm) was 25 days and 7 days respectively. The size of new skin scars ranged from 3mm to 11 mm. Clinical followed-up was performed in 34 cases for 36 months. Among them, no recurrence happened in 31 cases and new scar size ranged from 2mm to 8mm, while local recurrence happened in 3 cases whose scar size were less than 5 mm. Study Limitations: The cure rate of the therapy was 91.2%. Conclusion: The wound natural healing therapy is effective in treating tumor-like hypertrophic scar, which can prevent recurrence and has good cosmetic results.

Repair of large incisional hernias. To drain or not to drain. Randomized clinical trial

ABSTRACT PURPOSE: To evaluate the occurrence of seroma and surgical wound infection after surgery. METHODS: A total of 42 individuals with large incisional hernias were subjected toonlay mesh repair. Following the mesh placement, the participants were randomly allocated to two groups. In group 1, closed-suction drains were placed in the subcutaneous tissue, while progressive tension sutures were performed in group 2. The participants were subjected to clinical and ultrasound assessment to detect seroma and surgical wound infection at three time-points after surgery. RESULTS: The occurrence of seroma at the early, intermediate or late assessments was respectively 19.0%, 47.6%, 52.4% in group 1 and 28.6%, 57.1%, 42.9% in group 2 and was not significantly different between groups (p 0.469; 0.631; 0.619). Surgical wound infection occurred 19% in group 1 and 23.8% in group 2, without a significant difference between the groups (p>0.999). CONCLUSION: The frequency of seroma and infection did not exhibit significant differences between individuals subjected to onlay mesh repair of large incisional hernias with drains or progressive tension sutures without drainage.

Reconstrução labial após ressecção de tumores / Lip reconstruction after tumor resection

Introdução: O interesse antigo na reconstrução dos defeitos labiais pode ser explicado pela sua localização e pela singularidade da sua anatomia. Assim, o objetivo deste trabalho é discutir as melhores alternativas para a reconstrução labial. Métodos: Foi realizada uma análise retrospectiva de 50 casos submetidos à reconstrução primária dos lábios superior e inferior com o emprego de retalhos locais, no período de janeiro de 2000 a janeiro de 2014. Os defeitos foram divididos quanto à sua localização e quanto ao tamanho: defeitos que acometem até 1/3 do lábio e mais de 1/3 do lábio. O período de acompanhamento pós-operatório variou de 2 meses a 3 anos. Resultados: A idade dos pacientes variou entre 22 e 91 anos. A maior incidência foi na 7ª década de vida. Dentre as 50 reconstruções realizadas, 33 foram no lábio inferior (66%) e 17 no lábio superior (34%). Para defeitos pequenos, de até 1/3 do lábio, empregou-se a sutura simples (23 casos). Os demais 27 casos, cujos defeitos eram maiores que 1/3 do lábio, exigiram procedimentos com graus variáveis de complexidade. Conclusões: Para a reparação dos defeitos de até 1/3 do lábio inferior, a sutura direta é a melhor opção. Para a reconstrução de defeitos maiores que 1/3 do lábio inferior, devemos optar pelos retalhos de Gillies e Karapandzic, pois são confiáveis e capazes de restaurar a função labial. No caso de defeitos maiores que 50% do lábio, devemos evitar as técnicas de Gillies e Karapandzic, a fim de evitar a microstomia.

Introduction: Reconstruction of lip defects is popular owing to lip location and its anatomy. Thus, the objective of this work was to discuss the best options available for lip reconstruction. Methods: This retrospective study included 50 patients who had undergone primary upper and lower lip reconstruction using local flaps, between January 2000 and January 2014. The defects were divided according to their location and size: defects affecting up to 1/3 of the lip and affecting more than 1/3 of the lip. The postoperative follow-up varied from 2 months to 3 years. Results: Patient age ranged from 22 to 91 years. Most patients were in their seventies. Of the 50 reconstructions performed, 33 were in the lower lip (66%) and 17 in the upper lip (34%). For small defects affecting up to 1/3 of the lip, simple sutures were used (23 cases). The other 27 cases, in which more than 1/3 of the lip was affected, required interventions of different complexities. Conclusion: When repairing defects up to 1/3 of the lower lip, the direct suture is the most suitable option. For defects affecting more than 1/3 of the lower lip, the Gillies and the Karapandzic flaps should be chosen instead, as they are reliable and allow the reestablishment of lip functionality. For defects affecting >50% of the lip, and the Gillies and the Karapandzic flaps should not be considered, specifically to avoid microstomia.

Plicatura dos retos do abdome em dois planos versus plano único contínuo / Plication of the rectus abdominis muscles in one continuous and two planes

Introdução: A correção da diástase dos músculos retos do abdome é realizada principalmente pela sua plicatura, procedimento que consome muito tempo cirúrgico. O objetivo deste estudo é avaliar a eficácia e o tempo necessário para a correção da diástase dos retos do abdome comparando a plicatura com sutura contínua em plano único à plicatura em dois planos. Método: Foram incluídas 20 mulheres com história de pelo menos uma gestação. Foram randomizadas em dois grupos, um submetido à plicatura dos retos do abdome em dois planos (controle) e outro à sutura em plano único contínuo (estudo) com mononylon 2-0. Mediu-se o tempo necessário para a realização de cada uma das técnicas. Para análise estatística, foram usados os testes não paramétricos de Mann-Whitney, Friedman e Wilcoxon, considerando estatisticamente significante p < 0,05. Todas as pacientes foram submetidas à ultrassonografia previamente à cirurgia, 3 semanas e 6 meses de pós-operatório. Resultados: A plicatura do grupo estudo mostrou-se tão eficaz quanto à do grupo controle, mantendo seu resultado em longo prazo, apresentando diferença estatisticamente significante (p = 0,018) na comparação das medidas pré e pós-operatórias. No grupo estudo, porém, a plicatura consumiu menor tempo cirúrgico para ser realizada, também com diferença estatisticamente significante (p = 0,002). Conclusão: Com este estudo, pode ser concluído que tanto a sutura em dois planos como a em plano único contínuo são eficazes na correção da diástase dos retos do abdome e mantêm o resultado por longo tempo. Concluiu-se também que a técnica de sutura contínua demanda menor tempo para ser realizada.

Introduction: The correction of diastasis of the rectus abdominis muscles is primarily performed using the plication technique, which involves a surgical procedure. To evaluate the efficacy and the surgical time necessary to correct diastasis of the rectus abdominis muscles using plication and sutures in one continuous or two planes. Method: Twenty women with at least one pregnancy were included in the study. The study participants were randomized into two groups: the control group was subjected to plication in two planes, and the experimental group was subjected to plication using suture in one continuous plane with mono-nylon 2-0. The time required to perform each of these techniques was measured. For statistical analysis, the nonparametric Mann-Whitney test, Friedman test, and Wilcoxon test were used, and p-values of < 0.05 were considered statistically significant. All patients underwent ultrasonography before surgery, and at 3 weeks and 6 months postoperatively. Results: The plication technique was similarly effective in the two groups, achieving a long-term surgical outcome; however, the differences in the ultrasound measurements in the pre- and postoperative periods were statistically significant (p = 0.018). In addition, plication was performed in a significantly shorter time in the experimental group (p = 0.002). Conclusion: Sutures in one continuous plane and in two planes were effective in correcting diastasis of the rectus abdominis muscles, with the maintenance of a long-term surgical outcome. In addition, the continuous suture technique can be performed in a shorter time.

Mamoplastias redutoras e mastopexias realizadas no HC-UNICAMP: análise comparativa entre duas técnicas / Reduction mammoplasties and mastopexies performed at HC-UNICAMP: comparative analysis between two techniques

Introdução: Diferentes técnicas para mamoplastia redutora e mastopexia são descritas na literatura, visando a resultados que reconstituam o polo superior, ofereçam melhor projeção e proporcionem tratamento adequado para a ptose mamária. No entanto, devemos nos atentar para a segurança da técnica, com manutenção da vascularização, inervação dos tecidos e possibilidade de amamentação. Análise comparativa com pacientes operadas pela técnica com retalho de pedículo inferior e pacientes operadas pela técnica com sutura circular em bolsa. Métodos: Análise de 85 pacientes submetidas à mamoplastia redutora ou mastopexia sem implantes, entre janeiro de 2011 e dezembro de 2012, no Hospital de Clínicas da Unicamp. Foram excluídos 31 pacientes, as quais foram submetidas apenas à mamoplastia redutora pela técnica de Pitanguy (sem utilização de retalhos ou sutura circular). Dentre as 54 pacientes restantes, cinco foram posteriormente excluídas devido ao não comparecimento à consulta ou à não realização da ultrassonografia pós-operatória. Foram agrupadas 16 pacientes submetidas à sutura circular contínua e 33 pacientes operadas pela técnica de pedículo inferior. Resultados: Dados demográficos foram semelhantes nos dois grupos. Maior número de pequenas complicações e resultados insatisfatórios foi observado no grupo submetido à técnica de pedículo inferior, bem como maior índice de achados ultrassonográficos relevantes no pós-operatório. Conclusão: A técnica de sutura circular contínua apresentou elevado índice de satisfação, menor número de complicações e resultados mais duradouros quando comparados com a técnica de pedículo inferior, durante o período analisado.

Introduction: Several reduction mammoplasty and mastopexy techniques are described in the literature, with the aim of reconstituting the upper pole, offering better projection, and providing adequate treatment for breast ptosis. However, particular attention should be devoted to the safety of the technique, with maintenance of vascularization, tissue innervation, and the capability of breastfeeding. Female patients operated on with the inferior pedicle flap technique were compared with those operated on with purse-string circular suturing. Methods: Eighty-five patients who had undergone reduction mammoplasty or mastopexy without implants, between January 2011 and December 2012 at Unicamp's Clinical Hospital, were evaluated. Thirty-one patients who only underwent reduction mammoplasty by Pitanguy's technique (without the use of flaps or circular sutures) were excluded. Of the remaining 54 patients, five were subsequently excluded for not attending medical appointments or failure to have postoperative ultrasonography. A group of 16 patients who had undergone circular suturing and a group of 33 operated on by the inferior pedicle technique were considered. Results: Demographic data were similar for both groups. A higher number of minor complications and unsatisfactory results were observed in the group that underwent the inferior pedicle technique, who also had a higher rate of relevant post-operative ultrasonography events. Conclusion: The circular suturing technique resulted in a high satisfaction rate, lower number of complications, and longer lasting results than the inferior pedicle technique, during the period analyzed in this study.

Mamoplastia com retalho bipediculado de músculo peitoral: 30 anos de experiência com a técnica / Mammoplasty with bipedicled flap from the pectoral muscle: 30 years of experience

INTRODUÇÃO: Existem inúmeras técnicas de mamoplastia com objetivo de evitar a ptose tardia. Observamos em todas estas técnicas que a forma da mama após a sua báscula permaneceu com perda de preenchimento do seu polo superior. A associação da mamoplastia com o uso do retalho de base torácica associado ao retalho bipediculado de músculo peitoral maior tem sido utilizada devido ao bom resultado que é mantido num pós-operatório tardio. MÉTODO: Foram feitos mais de 4000 procedimentos utilizando a técnica do autor. Foi realizada a marcação de mamoplastia tradicional e confecção de retalho de pedículo inferior conforme descrito por Ribeiro. Divulsiona-se uma faixa do músculo peitoral e realiza-se a passagem completa do retalho torácico através da alça muscular com posterior fixação do retalho à parede torácica. Os retalhos muscular e glandular são envolvidos pelo tecido do polo superior fazendo se a sutura dos pilares laterais. RESULTADOS: Com a utilização da técnica de um retalho torácico, fixado por uma alça de músculo peitoral, obtivemos uma báscula mínima que forneceu um melhor resultado estético a longo prazo. Com esta técnica, o tecido mamário é dividido e reposicionado para o local desejado, mantendo a forma da mama e não dependendo do fechamento dérmico para se obter o contorno final. CONCLUSÃO: Observamos nos casos operados a manutenção do polo superior da mama mesmo tardiamente, redução da tensão sobre a cicatrização com consequente melhora do aspecto, ausência do movimento de báscula (ptose) pós-operatória, sem aumento significativo no tempo cirúrgico.

INTRODUCTION: Several breast augmentation techniques have been developed to avoid late ptosis. However, these techniques result in persistent pendulum and changed shape due to loss of filling in the upper pole. The combination of breast augmentation with a thoracic flap involving a bipedicled flap from the greater pectoral muscle has been used with good results that are maintained in late postoperative periods. METHOD: More than 4,000 procedures were performed using the author's technique. The marking of traditional mammoplasty and construction of the inferior pedicle flap were performed as described by Ribeiro. A pectoral muscle strap was divulsed and the thoracic flap passed through and attached to the chest wall. The muscle and glandular flaps were wrapped by the upper pole tissue and sutured to the lateral breast pillars. RESULTS: Use of the thoracic flap technique fixed by a pectoral muscle strap results in minimum pendulum, which provides better long-term aesthetic results. With this technique, the breast tissue is divided and repositioned in the desired location while maintaining the breast shape rather than depending on the dermal closure to provide the final shape. CONCLUSION: This technique provides long-term preservation of the upper breast pole and reduced scar tension with consequent aspect improvement; it also eliminates post-operative pendulum movement (ptosis) without significantly increasing surgical time.

Ultrasound biomicroscopy confirmation of corneal overriding due to improper suturing of full-thickness corneal laceration / Confirmação por biomicroscopia ultrassônica de encavalamento corneano devido à sutura inadequada de laceração de espessura total da córnea

We herein present a case with corneal overriding due to improper suturing of a full-thickness corneal laceration. There was a 2.5-mm difference between horizontal and vertical white-to-white measurements in the cornea. However, slit lamp examination failed to demonstrate the exact architecture of the laceration. Ultrasound biomicroscopy defined the wound edges thoroughly and confirmed the presence of corneal overriding. Six weeks after suture enhancement, the abnormal oval appearance of the cornea was absent and correct apposition of the corneal edges was seen on ultrasound biomicroscopy. Ultrasound biomicroscopy can be used in preoperative surgical planning of cases with complicated corneal lacerations. It can be used to adjust and enhance wound architecture in eyes with penetrating injury.

Apresentamos um caso com encavalamento corneano devido à sutura inadequada de uma laceração da córnea de espessura total. Houve uma diferença 2,5 mm entre as medidas do branco ao branco horizontais e verticais na córnea. No entanto, o exame da lâmpada de fenda não conseguiu demonstrar a arquitetura exata da laceração. A biomicroscopia ultrassônica definiu as bordas da ferida completamente e confirmou a presença de encavalamento da córnea. Seis semanas após a melhora da sutura, a aparência oval anormal da córnea havia desaparecido, e a correta aposição das bordas da córnea foi identificada na biomicroscopia ultrassônica. A biomicroscopia ultrassônica pode ser usada no planejamento cirúrgico pré-operatório de casos com lacerações corneanas complicadas. Ela pode ser utilizada para ajustar e melhorar a arquitetura da ferida em olhos com lesão penetrante.

Uso de suturas uterinas compressivas na hemorragia pós-parto / Use of uterine compression sutures in postpartum hemorrhage

A hemorragia pós-parto é uma complicação presente em mais de 18% dos nascimentos e é responsável por cerca de 25 a 30% das mortes maternas no mundo. Nas últimas décadas, várias técnicas conservadoras visando o controle hemorrágico no período pós-parto têm sido relatadas, com destaque para as ligaduras vasculares, suturas uterinas compressivas, embolização arterial, balões intrauterinos e a interrupção do ato operatório com laparostomia, empacotamento pélvico e posterior abordagem cirúrgica. O presente artigo apresenta uma revisão das suturas uterinas compressivas, com destaque para a cronologia de criação das técnicas de execução, e as publicações em periódicos. São descritas as suturas de Schnarwyler, B-Lynch, Cho, Hayman, Bhal, Pereira, Ouabha, Hackethal, Meydanli, Marasinghe-Condous, Matsubara-Yano, Zheng e a técnica de Halder. Foram detalhadas também as indicações, as técnicas associadas e as complicações.(AU)

Application of Self-retaining Bidirectional Barbed Absorbable Suture in Retroperito- neoscopic Partial Nephrectomy

ObjectiveTo investigate the safety and feasibility of self-retaining bidirectional barbed absorbable suture application in retroperitoneoscopic partial nephrectomy.Materials and MethodsFrom Sep 2011 and Aug 2012, 76 cases of retroperitoneoscopic partial nephrectomy were performed at our hospital. The patients were divided into two groups: self-retaining barbed suture (SRBS) group (n = 36) and non-SRBS group (n = 40). There was no significant difference in age, sex, tumor size and location between the two groups. Clinical data and outcomes were analyzed retrospectively.ResultsAll 76 cases of retroperitoneoscopic partial nephrectomy were successfully performed, without conversion to open surgery or serious intraoperative complications. In the SRBS group, the suture time, warm ischemia time and operation blood loss were significantly shorter than that of non-SRBS group (p < 0.01), and operation time and hospital stay were shorter than that of non-SRBS group (p < 0.05).ConclusionsThe application of self-retaining bidirectional barbed absorbable suture in retroperitoneoscopic partial nephrectomy could shorten suture time and warm ischemia time, with good safety and feasibility, worthy of being used in clinic.

Plicatura e reinserção da aponeurose do músculo levantador da pálpebra superior com sutura contínua na correção cirúrgica da ptose palpebral leve e moderada-experiência pessoal / Plication and reinsertion of the aponeurosis of the lifting muscle of the upper eyelid with continuous suture in the surgical correction of light and moderate eyelid ptosis - personal experience

Introdução: A blefaroptose ou ptose palpebral caracteriza-se pelo posicionamento anômalo da pálpebra superior em relação à sua posição normal, que é de 1 a 2 mm abaixo do limbo superior da íris; pode variar, apresentando desde uma queda discreta, até a oclusão total da fenda palpebral. Em geral, trata-se de deficiência muscular ou nervosa, de etiologia congênita ou adquirida, que resulta na impossibilidade de elevação completa da pálpebra superior, podendo também ocorrer por desinserção aponeurótica. Apresenta-se neste trabalho a tática da sutura contínua da aponeurose do músculo levantador ao tarso, ou mesmo na sua plicatura, para o tratamento da ptose leve ou moderada. Métodos: No período de 2006 a 2012, foram realizadas 26 cirurgias, abordando a aponeurose do músculo levantador com encurtamento na relação 4:1, usando sutura contínua em duplo sentido, finalizando-a com ponto em formato de oito. Resultados: Em 88,32% dos casos, os resultados foram bons e, em 11,68%, regulares. Apenas um caso evoluiu com retração na pálpebra superior, elevando o sulco palpebral. Observou-se correção incompleta, com ptose residual de 2 a 4 mm em 2 casos, os quais foram submetidos a revisão cirúrgica após 6 meses.

Introduction: Blefaroptose or eyelid ptosis is characterized by the anomalous positioning of the upper eyelid in relation to its normal position, which is 1 to 2 mm below the upper margin of the iris. It can vary from a slight descent to a total occlusion of the eyelid slit. In general, whether caused by a muscular or nerve deficiency, congenital or acquired, it results in the impossibility to use the muscle to raise the eyelid. It can also occur due to the detachment of the aponeurosis. Presented in this study is the tactic of continuous suture of the aponeurosis of the lifting muscle at the tarsus or at its foldings, for the treatment of light or moderate ptosis. Methods: In the period from 2006 to 2012, we analyzed 26 eyelids submitted to surgical treatment. 24 were operated upon, addressing the aponeurosis of the raising muscle with a shortening in the relation of 4:1 and, in 2 cases, with the reinsertion of the aponeurosis in the raising muscle of the eyelid, using continuous two-way suture completing the same with a stitch in a figure eight. Results: In 88.32% of the cases, the results were considered good, and in 11.68% satisfactory.

Resultados da correção simplificada com enxerto único no defeito septal atrioventricular completo / Results of simplified single-patch repair for complete atrioventricular septal defect

FUNDAMENTO: Desde que Wilcox, em 1997, descreveu uma forma simplificada de correção do Defeito Septal Atrioventricular (DSAV) com enxerto único, diversos estudos têm sido realizados comparando-a à técnica com duplo enxerto. OBJETIVO: Relatar os resultados em médio e longo prazos da correção de DSAV completo pela técnica simplificada de enxerto único. MÉTODOS: Estudo retrospectivo de 16 casos consecutivos arrolados entre janeiro de 2001 e dezembro de 2011. A idade média foi 18,31 ± 34,19 meses (2 meses - 11 anos) e o peso 7,80 ± 6,12 Kg (3,77 - 25,0 Kg); 6 pacientes eram do sexo masculino e 14 eram portadores de Síndrome de Down. O tempo de seguimento médio foi de 54,97 ± 47,79 meses. RESULTADOS: O tempo médio de circulação extracorpórea foi 74,63 ± 18,48 min (49 - 112 min) e o de pinçamento aórtico, de 46,44 ± 11,89 min (34 - 67 min). Foram observados dois óbitos hospitalares (12,5%), ambos por causa cardiovascular. Três pacientes foram reoperados por regurgitação da valva atrioventricular (VA) esquerda e dois apresentaram bloqueio atrioventricular (BAV) completo com necessidade de implante de marca-passo definitivo. Não houve nenhum caso de obstrução da via de saída do ventrículo esquerdo. Os 14 pacientes sobreviventes permanecem assintomáticos, 10 deles com insuficiência da valva VA esquerda leve (71,42%). CONCLUSÃO: A técnica simplificada com enxerto único para correção de DSAV completo mostrou-se factível, associada à correção adequada dos defeitos e à favorável evolução clínica e ecocardiográfica nos 57,97 meses de seguimento médio avaliados.

BACKGROUND: Since Wilcox's description of the simplified single-patch technique for atrioventricular septal defect (AVSD) repair in 1997, several studies have compared that technique with the two-patch technique. OBJECTIVE: To report the mid- and long-term results of the simplified single-patch technique for complete AVSD repair. METHODS: Retrospective study of 16 consecutive cases between January 2001 and December 2011. The patients' mean age was 18.31 ± 34.19 months (2 months - 11 years), and their mean weight, 7.80 ± 6.12 kg (3.77 - 25.0 kg). Six patients were males and 14 had Down syndrome. Mean follow-up duration was 54.97 ± 47.79 months. RESULTS: Mean cardiopulmonary bypass time was 74.63 ± 18.48 min (49 - 112 min), and mean aortic cross-clamp time, 46.44 ± 11.89 min (34 - 67 min). Two patients died during hospitalization (12.5%), both of cardiovascular causes. Three patients underwent reoperation due to left atrioventricular (AV) valve regurgitation, and two had third-degree VA block, requiring permanent pacemaker implantation. No patient had left ventricular outflow tract obstruction. The 14 surviving patients remain asymptomatic, ten of whom with mild left VA valve regurgitation (71.42%). CONCLUSION: The simplified single-patch technique for complete AVSD repair proved to be feasible, providing adequate correction of the defects and favorable clinical and echocardiographic outcome in the mean 57.97-month follow-up.
