Management and outcomes of gastric leak after sleeve gastrectomy: results from the 2010-2020 national registry / 中华医学杂志(英文版)

BACKGROUND@#Management of gastric leak after sleeve gastrectomy (SG) is challenging due to its unpredictable outcomes. We aimed to summarize the characteristics of SG leaks and analyze interventions and corresponding outcomes in a real-world setting.@*METHODS@#To retrospectively review of 15,721 SG procedures from 2010 to 2020 based on a national registry. A cumulative sum analysis was used to identify a fitting curve of gastric leak rate. The Kaplan-Meier method and log-rank tests were performed to calculate and compare the probabilities of relevant outcomes. The logistic regression analysis was conducted to determine the predictors of acute leaks.@*RESULTS@#A total of 78 cases of SG leaks were collected with an incidence of 0.5% (78/15,721) from this registry (6 patients who had the primary SG in non-participating centers). After accumulating 260 cases in a bariatric surgery center, the leak rate decreased to a stably low value of under 1.17%. The significant differences presented in sex, waist circumference, and the proportion of hypoproteinemia and type 2 diabetes at baseline between patients with SG leak and the whole registry population ( P = 0.005, = 0.026, <0.001, and = 0.001, respectively). Moreover, 83.1% (59/71) of the leakage was near the esophagogastric junction region. Leakage healed in 64 (88.9%, 64/72) patients. The median healing time of acute and non-acute leaks was 5.93 months and 8.12 months, respectively. Acute leak (38/72, 52.8%) was the predominant type with a cumulative reoperation rate >50%, whereas the cumulative healing probability in the patients who required surgical treatment was significantly lower than those requring non-surgical treatment ( P = 0.013). Precise dissection in the His angle area was independently associated with a lower acute leak rate, whereas preservation ≥2 cm distance from the His angle area was an independent risk factor.@*CONCLUSIONS@#Male sex, elevated waist circumference, hypoproteinaemia, and type 2 diabetes are risk factors of gastric leaks after SG. Optimizing surgical techniques, including precise dissection of His angle area and preservation of smaller gastric fundus, should be suggested to prevent acute leaks.

Ventana cortical anterior para extracción de vástago en revisión de artroplastia total de cadera: una alternativa a la osteotomía trocantérica extendida / Anterior cortical window for stem extraction in total hip arthroplasty revision: an alternative to extended trochanteric osteotomy

Total hip arthroplasty (THA) is a safe and effective procedure in patients with end-stage ostheoarthritis. In the last years the indication for THA is increasingly in younger patients, associated with rising of life expectancy, this imply an increase in revision surgeries for various causes such as: aseptic loosening, fractures and infections. In this context and in view of the need to replace the femoral component, alternatives to the classic extended trochanteric osteotomy (ETO) arise, such as the anterior cortical window (ACW), which allows the rate of complications to be reduced with excellent results. We present the case of a 51-year-old patient who sustained one episode of dislocation, who required revision surgery due to aseptic loosenig, where the ACW was used for the extraction of the stem. In addition, a review of the literature was made to show advantages and complications regarding ETO.

Operaciones en dos etapas, utilizando sutura de grosor flexible en el tratamiento de fistula anal de tipo alto en una curación rápida de estimulación y tasa de recurrrencia más baja / Two staged operations using loose thick seton suture in the treatment of high type fistula in ano stimulate rapid healing and lower recurrence rate

Antecedentes: la fístula de ano es un problema crónico para los pacientes. Causa angustia debido al mal olor y la suciedad con infecciones y secreciones recurrentes. La recurrencia y la lesión del esfínter anal fueron las complicaciones más críticas después de la cirugía. La colocación de un setón suelto y grueso fue la operación quirúrgica más prometedora. Reducir el tiempo de colocación del setón para disminuir el sufrimiento de los pacientes por la suciedad y múltiples apósitos. Pacientes y métodos: estudio retrospectivo. Cien pacientes con fístula anal alta tratados quirúrgicamente en la ciudad médica de Al-Sader y en la clínica privada diaria de Al-Najaf, ciudad de Najaf, Irak, desde febrero de 2018 hasta marzo de 2019. Se han tomado imágenes de fistulografía y resonancia magnética de todos los pacientes. Después de eso, se realiza una fistulectomía con sutura de setón suelta y gruesa durante tres meses. Los pacientes con persistencia del trayecto de trayecto fistuloso fueron sometidos a una segunda cirugía y una tercera operación hasta su completa curación. Resultados: Cien pacientes con fístula de tipo alto en ano con 96 varones (96%) y mujeres 4 (4%). La tasa de curación completa entre los pacientes masculinos después de la primera operación fue de 90 (93%), mientras que las mujeres mostraron una tasa de curación completa de 4 (100%) después de la primera operación. Tres de los pacientes varones restantes con un tracto de fístula alto persistente mostraron una curación completa después de la segunda operación, mientras que en 3 (3%) la tasa de curación completa fue del 100% después de la tercera operación. Conclusión: Un setón suelto y grueso colocado en un tracto de fístula de tipo alto durante tres meses brinda una excelente protección al esfínter anal externo con una tasa de recurrencia menor y una curación rápida.

Background: Fistula in ano is a chronic problem for the patients. It causes distressing because of foul odour and soiling with recurrent infection and discharge. Recurrence and anal sphincter injury were the most critical complications following surgery. Loose, thick seton placement was the most promising surgical operation. To reduce the time of seton placement, therefore, decreasing the suffering of patients from soiling and multiple dressing. Patients and Methods: A retrospective study. One hundred patients with high type fistula in ano treated surgically in Al-Sader Medical city and Al-Najaf daily private clinic, Najaf city, Iraq from Feb 2018 to March 2019. Fistulography and magnetic resonance imaging have taken from all patients. After that, fistulectomy with loose, thick seton suture placed for three months. Patients with the persistence of high fistula tract underwent a second surgery and third operation until complete healing. Results: One hundred patients with high type fistula in ano with male 96 (96%) and female patients were 4 (4%). The rate of complete healing among male patients after the first operation was 90 (93%), while female patients showed a 4(100%) rate of complete healing after the first operation. Three of the remaining male patients with persistently high fistula tract showed complete healing after the second operation, whereas 3 (3%) the rate of complete healing was 100% after the third operation. Conclusion: A Loose, thick seton placed in high type fistula tract for three months provides excellent protection to the external anal sphincter with less recurrence rate and rapid healing

La mortalidad fue de 30,1 por ciento y el tromboembolismo pulmonar la causa directa de muerte en 12,3 por ciento de los casos. Conclusiones: Casi la totalidad de los casos fueron reintervenidos luego de las 48 horas y las dos terceras partes resolvieron en la primera intervención. La peritonitis generalizada y los abscesos intrabdominales fueron la causa de la reintervención en un número importante(AU)

Introduction: Abdominal surgery re-interventions cause high mortality in general surgery services. Objective: To characterize morbidity and mortality of urgent and elective abdominal surgery re-interventions in the general surgery service of Manuel Ascunce Domenech University Hospital. Methods: A cross-sectional, descriptive, observational study was carried out with patients who required abdominal surgical re-intervention. The universe consisted of 236 patients who met the inclusion criteria. Descriptive statistical methods and calculations with percentage values were used. Results: There was a predominance of the age group 40-49 years and the male sex, accounting for 25 percent and 64.8 percent, respectively. Regarding time of performance of re-intervention, 72.5 percent was carried out after 48 hours. 88.6 percent of the patients had, in the first re-intervention, a solution for the cause that originated it. The most frequent causes were generalized peritonitis, followed by intraabdominal abscesses, accounting for 19.5 percent and 17.4 percent, respectively. Mortality was 30.1 percent and pulmonary embolism was the direct cause of death in 12.3 percent of cases. Conclusions: Almost all the cases were re-intervened after 48 hours and two thirds had a solution the first re-intervention. Generalized peritonitis and intraabdominal abscesses were the cause of re-intervention, in a significant number(AU)

Usefulness of preoperative venography in patients with cardiac implantable electronic devices submitted to lead replacement or device upgrade procedures / Utilidade da Venografia Pré-Operatória em Procedimentos de Troca de Cabos-Eletrodos ou Mudança do Modo de Estimulação

Abstract Background: Venous obstructions are common in patients with transvenous cardiac implantable electronic devices, but they rarely cause immediate clinical problems. The main consequence of these lesions is the difficulty in obtaining venous access for additional leads implantation. Objectives: We aimed to assess the prevalence and predictor factors of venous lesions in patients referred to lead reoperations, and to define the role of preoperative venography in the planning of these procedures. Methods: From April 2013 to July 2016, contrast venography was performed in 100 patients referred to device upgrade, revision and lead extraction. Venous lesions were classified as non-significant (< 50%), moderate stenosis (51-70%), severe stenosis (71-99%) or occlusion (100%). Collateral circulation was classified as absent, discrete, moderate or accentuated. The surgical strategy was defined according to the result of the preoperative venography. Univariate analysis was used to investigate predictor factors related to the occurrence of these lesions, with 5% of significance level. Results: Moderate venous stenosis was observed in 23%, severe in 13% and occlusions in 11%. There were no significant differences in relation to the device side or the venous segment. The usefulness of the preoperative venography to define the operative tactic was proven, and in 99% of the cases, the established surgical strategy could be performed according to plan. Conclusions: The prevalence of venous obstruction is high in CIED recipients referred to reoperations. Venography is highly indicated as a preoperative examination for allowing the adequate surgical planning of procedures involving previous transvenous leads.

Resumo Fundamento: Obstruções venosas são frequentes em portadores de dispositivos cardíacos eletrônicos implantáveis (DCEI) endocárdicos, mas raramente causam problemas clínicos imediatos. A principal consequência destas lesões é a dificuldade para obtenção de via de acesso para o implante de novos cabos-eletrodos. Objetivos: Determinar a prevalência de lesões venosas em candidatos a reoperações envolvendo o manuseio de cabos-eletrodos, e definir o papel da venografia pré-operatória no planejamento desses procedimentos. Métodos: De abril de 2013 a julho de 2016, 100 pacientes com indicação de troca de cabos-eletrodos, ou mudança no modo de estimulação, realizaram venografia com subtração digital no período pré-operatório. As lesões venosas foram classificadas em: não significativas (< 50%), moderadas (51-70%), graves (71-99%) ou oclusivas (100%), e a circulação colateral, em ausente, discreta, moderada ou acentuada. A estratégia cirúrgica foi definida a partir do resultado deste exame. Empregou-se análise univariada para a pesquisa de fatores de risco relacionados à ocorrência dessas lesões, com nível de significância de 5%. Resultados: Obstruções venosas moderadas foram observadas em 23%, graves em 13% e oclusões em 11% dos pacientes estudados, não sendo identificadas diferenças significativas em sua distribuição em relação ao lado do implante, ou do segmento venoso. A utilidade do exame para definição da tática operatória foi comprovada, sendo que em 99% dos casos, a estratégia cirúrgica estabelecida pode ser executada. Conclusões: A prevalência de obstruções venosas é elevada em portadores de DCEI que serão submetidos a reoperações. A venografia é altamente indicada como exame pré-operatório para o adequado planejamento cirúrgico de procedimentos envolvendo cabos-eletrodos transvenosos previamente implantados.

Late secondary urological reconstruction of separated ischiopagus twins with exstrophic bladder and urinary incontinence / Reconstrução urológica tardia de gêmeos isquiópagos com extrofia de bexiga e incontinência urinária

ABSTRACT We report a case of secondary urinary reconstruction of previously separated conjoined twins with exstrophic bladder and urinary incontinence. Patients were male and aged 13-year-old. Twin one had a history of failed enterocystoplasty that extruded and was visible like an exstrophic neobladder. He underwent a procedure to close bladder neck and reconfigure abdominal wall. After the procedure the patient developed a fistula that was treated, but it persisted and, for this reason, a catheterizable pouch was constructed and native bladder was discarded. Twin two required the immediately construction of catheterizable pouch using the Macedo's technique. Currently, both patients are continent at 4 hour intervals. The mean follow-up was 8 months. Modern continent urinary diversion techniques offer new perspectives and hope for such complex population.

RESUMO Relata-se caso de reconstrução urinária em gêmeos siameses previamente separados com apresentação clínica de bexiga extrófica e incontinência urinária. Os dois pacientes eram do sexo masculino com idade de 13 anos. O primeiro gêmeo apresentava falha da enterocistoplastia com extrusão e visualização da neobexiga extrófica, tendo sido submetido ao fechamento do colo vesical e à reconfiguração da parede abdominal. Após o procedimento, o paciente desenvolveu fístula, que foi tratada, mas persistiu. Posteriormente, optamos por bolsa cateterizável, descartando a bexiga nativa. O segundo gêmeo foi submetido à construção imediata de bolsa cateterizável, por meio da técnica de Macedo. Atualmente, ambos os pacientes estão continentes em intervalos de 4 horas. O seguimento médio foi de 8 meses. As atuais técnicas de derivação urinária oferecem novas perspectivas e esperança para esta população complexa.

Causas de rinoplastía secundaria: análisis de 277 casos / Secondary rhinoplasty causes: analysis of 277 cases

Introducción: La rinoplastía secundaria cada día es más frecuente debido a la creciente popularidad de la cirugía estética y también por las mayores expectativas del paciente y del cirujano. La rinoplastía secundaria ha llegado a ser un campo en evolución con desafíos únicos. Para enfrentarlo adecuadamente el cirujano debe analizar y comprender las necesidades específicas del paciente y las causas anatómicas que generaron el problema y cómo corregirlo. Objetivo: Identificar los problemas anatómicos más frecuentemente encontrados en 277 rinoplastías secundarias y sistematizarlos para una mejor evaluación preoperatoria y planificación quirúrgica. Material y método: Análisis retrospectivo de 1.160 rinoplastías operadas por el otorrinolaringólogo Dr. Luis Villarroel entre el 1 de enero de 2006 y el 31 de marzo de 2015, de las cuales 277 son rinoplastías secundarias (24%). En ellas se encontraron 1.197 problemas o deformidades (4,3 promedio), que se dividieron en tercio superior, medio, inferior y endonasales, con una subdivisión de deformidades individuales dentro de cada grupo. También se comparan los resultados encontrados según si la cirugía primaria fue de otro cirujano (rinoplastías secundarias) o del mismo autor (rinoplastías de revisión). Resultados: El 85% de los pacientes presentó problemas en el tercio inferior. Los problemas más frecuentes fueron desviación del tabique nasal (problema endonasal) (56%), punta hiporotada (47%), desviación del dorso óseo (34%) y desviación del dorso cartilaginoso (30%). Las rinoplastías de revisión, comparadas con las secundarias, presentan un porcentaje mayor de problemas de insuficiente resección del dorso óseo y menos dorsos cartilaginosos estrechos. Conclusión: Existen diferentes razones por las que un paciente busca una rinoplastía secundaria. Es importante conocer las causas más frecuentes con el fin de identificar los errores cometidos en el primer caso y evitar dichas prácticas. Es preferible una cirugía primaria conservadora porque evita problemas difíciles de resolver. Esta clasificación nos ayuda a sistematizar el análisis preoperatorio, a saber, dónde estamos teniendo problemas y así corregirlos y obtener mejores resultados quirúrgicos.

Introduction: Secondary rhinoplasty is becoming increasingly common due to the growing popularity of cosmetic surgery and also by higher expectations of the patient and the surgeon. Secondary rhinoplasty has become an evolving field with unique challenges. To repair the surgeon must properly analyze and understand the specific concerns of the patient and the anatomical causes of why you need a new operation. Aim: To identify anatomical problems most frequently found in 277 secondary and systematize rhinoplasty for better preoperative evaluation and surgical planning. Material and method: Retrospective analysis of 1160 rhinoplasty operated by otolaryngologist Dr. Luis Villarroel between January 1006 and March 31, 2015, of which 277 are secondary rhinoplasty (24%). In this study we found 1197 problems or deformities (average 4.3), They were classified into upper, middle, bottom third ,and endonasal, with an individual deformities subdivision within each group. The results are compared if the primary surgery was another surgeon (secondary rhinoplasty of others) or by the same author (revision rhinoplasty). Results: 85% of patients had problems in the lower third. The most common individual problems identificated were deviated septum (56%), drop tip (47%), bone dorsum deviation (34%), and cartilaginous dorsum desviation (30%). The author presents a higher percentage of insufficient bone resection and less cartilaginous dorsum narrow. Conclusion: There are different reasons why a patient seeks a secondary rhinoplasty. It is important to know the most frequent causes in order to identify the mistakes made in the first instance and avoid them. It's preferable one conservative primary surgery because it avoids difficult problems. This classification helps us to systematize the preoperative analysis and better results.

Artificial urinary sphincter revision for urethral atrophy: comparing single cuff downsizing and tandem cuff placement

ABSTRACT Objective To compare outcomes for single urethral cuff downsizing versus tandem cuff placement during artificial urinary sphincter (AUS) revision for urethral atrophy. Materials and Methods We identified 1778 AUS surgeries performed at our institution from 1990-2014. Of these, 406 were first AUS revisions, including 69 revisions for urethral atrophy. Multiple clinical and surgical variables were evaluated for potential association with device outcomes following revision, including surgical revision strategy (downsizing a single urethral cuff versus placing tandem urethral cuffs). Results Of the 69 revision surgeries for urethral atrophy at our institution, 56 (82%) were tandem cuff placements, 12 (18%) were single cuff downsizings and one was relocation of a single cuff. When comparing tandem cuff placements and single cuff downsizings, the cohorts were similar with regard to age (p=0.98), body-mass index (p=0.95), prior pelvic radiation exposure (p=0.73) and length of follow-up (p=0.12). Notably, there was no difference in 3-year overall device survival compared between single cuff and tandem cuff revisions (60% versus 76%, p=0.94). Likewise, no significant difference was identified for tandem cuff placement (ref. single cuff) when evaluating the risk of any tertiary surgery (HR 0.95, 95% CI 0.32-4.12, p=0.94) or urethral erosion/device infection following revision (HR 0.79, 95% CI 0.20-5.22, p=0.77). Conclusions There was no significant difference in overall device survival in patients undergoing single cuff downsizing or tandem cuff placement during AUS revision for urethral atrophy.

The clinical significance of a second transurethral resection for T1 high-grade bladder cancer: Results of a prospective study

PURPOSE: This study was designed to estimate the value of a second transurethral resection of bladder tumor (TURBT) procedure in patients with initially diagnosed T1 high-grade bladder cancer. MATERIALS AND METHODS: Between August 2009 and January 2013, a total of 29 patients with T1 high-grade bladder cancer prospectively underwent a second TURBT procedure. Evaluation included the presence of previously undetected residual tumor, changes to histopathological staging or grading, and tumor location. Recurrence-free and progression-free survival curves were generated to compare the prognosis between the groups with and without residual lesions by use of the Kaplan-Meier method. RESULTS: Of 29 patients, 22 patients (75.9%) had residual disease after the second TURBT. Staging was as follows: no tumor, 7 (24.1%); Ta, 5 (17.2%); T1, 6 (20.7%); Tis, 6 (20.7%); Ta+Tis, 1 (3.4%); T1+Tis, 1 (3.4%); and > or =T2, 3 (10.3%). The muscle layer was included in the surgical specimen after the initial TURBT in 24 patients (82.7%). In three patients whose cancer was upstaged to pT2 after the second TURBT, the initial surgical specimen contained the muscle layer. In the group with residual lesions, the 3-year recurrence-free survival and 3-year progression-free survival rates were 50% and 66.9%, respectively, whereas these rates were 68.6% and 68.6%, respectively, in the group without residual lesions. This difference was not statistically significant. CONCLUSIONS: Initial TURBT does not seem to be enough to control T1 high-grade bladder cancer. Therefore, a routine second TURBT procedure should be recommended in patients with T1 high-grade bladder cancer to accomplish adequate tumor resection and to identify patients who may need to undergo prompt cystectomy.

Reoperação da valva mitral minimamente invasiva sem pinçamento da aorta / Minimally invasive redo mitral valve surgery without aortic crossclamp

INTRODUÇÃO: Reoperações da valva mitral apresentam maior índice de complicações quando comparadas com a primeira cirurgia. Com o domínio das técnicas videoassistidas para as primeiras cirurgias da valva mitral, os casos de reoperações passaram a despertar interesse para esses procedimentos menos invasivos. OBJETIVO: Analisar os resultados e as dificuldades técnicas da retroca valvar mitral minimamente invasiva em 10 pacientes. MÉTODO: A circulação extracorpórea foi instalada por meio de colocação de cânulas femorais e cânula na veia jugular interna direita, conduzida em 28 graus de temperatura em fibrilação ventricular. Realizada toracotomia lateral direita com 5 a 6 cm no terceiro ou quarto espaço intercostal. Pericárdio foi descolado apenas na região do átrio esquerdo no ponto da atriotomia. A aorta não foi pinçada. RESULTADOS: Foram avaliados 10 pacientes com idade média de 56,9±10,5 anos. Quatro encontravam-se em ritmo de fibrilação atrial e 6 em ritmo sinusal. O tempo médio entre a primeira operação e a reoperações foi de 11 ± 3,43 anos. O EuroSCORE médio do grupo foi de 8,3 ± 1,82. O tempo médio de fibrilação ventricular e de circulação extracorpórea foi respectivamente 70,9 ± 17,66 min e 109,4 ± 25,37 min. O tempo médio de internamento foi de 7,6 ± 1,5 dias. Não houve óbitos nessa série. CONCLUSÃO: A reoperação da valva mitral pode ser feita por meio de técnicas menos invasivas com bons resultados imediatos e baixa morbimortalidade. Entretanto, esse tipo de cirurgia requer maior tempo de circulação extracorpórea, especialmente nos casos em que o paciente já tenha uma prótese. A presença de uma mínima insuficiência aórtica também torna esse procedimento tecnicamente mais desafiador.

INTRODUCTION: Reoperations of the mitral valve have a higher rate of complications when compared with the first surgery. With the field of video-assisted techniques for the first surgery of mitral valve became routine, reoperation cases began to arouse interest for this less invasive procedures. OBJECTIVE: To assess the results and the technical difficulties in 10 patients undergoing minimally invasive redo mitral valve surgery. METHOD: Cardiopulmonary bypass was installed through a cannula placed in the femoral vessels and right internal jugular vein, conducted in 28 degrees of temperature in ventricular fibrillation. A right lateral thoracotomy with 5 to 6 cm in the third or fourth intercostal space was done, pericardium was displaced only at the point of atriotomy. The aorta was not clamped. RESULTS: Ten patients with mean age of 56.9 ± 10.5 years, four were in atrial fibrilation rhythm and six in sinusal. Average time between first operation and reoperations was 11 ± 3.43 years. The mean EuroSCORE group was 8.3 ± 1.82. The mean ventricular fibrillation and cardiopulmonary bypass was respectively 70.9 ± 17.66 min and 109.4 ± 25.37 min. The average length of stay was 7.6 ± 1.5 days. There were no deaths in this series. CONCLUSION: Mitral valve reoperation can be performed through less invasive techniques with good immediate results, low morbidity and mortality. However, this type of surgery requires a longer duration of cardiopulmonary bypass, especially in cases where the patient already has prosthesis. The presence of a minimal aortic insufficiency also makes this procedure technically more challenging.

Parallel Shunt for the Treatment of Transjugular Intrahepatic Portosystemic Shunt Dysfunction

OBJECTIVE: To investigate the safety, efficacy and long-term patency of parallel shunts (PS) in the management of the transjugular intrahepatic portosystemic shunt (TIPS) dysfunction. MATERIALS AND METHODS: Between March 2007 and October 2010, 18 patients (13 men and 5 women) who underwent TIPS revision with the creation of PS were evaluated retrospectively. In the first 10 patients, a 10-mm-diameter Wallgraft endoprosthesis was deployed; in the latter 8 patients, an 8-mm-diameter Fluency endoprosthesis was deployed. RESULTS: The creation of PS was technically successful in all patients. The mean +/- standard deviation portosystemic pressure gradient before and after the procedure was 25.5 +/- 7.3 mm Hg (range, 16-37 mm Hg) and 10.9 +/- 2.3 mm Hg (range, 7-16 mm Hg), respectively. The duration of follow-up was 16.7 +/- 10.8 months (range, 6-42 months). The primary shunt patency rates at 12 months after the creation of PS was 70% with Wallgraft endoprostheses and 87.5% with Fluency endoprostheses. CONCLUSION: TIPS revision with the creation of PS is a safe, effective and durable method for treating shunt dysfunction.

Fístula enteroatmosférica y uso del VAC: a propósito de un caso / Enteroatmospheric fistula and vaccum assited closure: report of a case

Las fístulas gastrointestinales asociadas con abdomen abierto posterior a cirugía abdominal mayor son una complicación grave. El manejo es extremadamente difícil y la mortalidad bastante alta a pesar de los modernos avances médicos. Aquellos pacientes que sobreviven al daño metabólico y fisiopatológico inicial, requieren en su mayoría cierre quirúrgico de la fístula lo cual es técnicamente complejo. Presentamos el caso de un paciente con una neoplasia de rectosigma que se abordó por laparoscopia y desarrolló una fístula enteroatmosférica sobre la incisión de Pfannestiel que se utilizó para la extracción de la pieza. Conclusión: El cierre asistido por vacío artesanal y el manejo nutricional adecuado permiten la mejoría en pacientes con fístulas complejas logrando las condiciones adecuadas para el cierre definitivo.

The gastrointestinal fistula associated to posterior open abdominal trauma or abdominal surgery implies severe complications. The handling of these cases is extremely hard and mortality is very high despite medical advances. Those patients who survive the initial metabolic and phisycopathological damages require, on most cases, a surgical closure of the fistula which is a very complex procedure technically. We describe the case of a patient with a rectosigmoid neoplasm that was addressed laparoscopically and enteroatmospheric fistula just developing on phannestiel incision was used to extract the neoplasm. Conclusion: The closure assisted by “hand made vacuum” and adequate nourishment allows recovering patients with complex fistulas to achieve adequate conditions for definitive closure.

Tratamento de mamas tuberosas com incisões combinadas / Treatment of tuberous breast with combined incisions

INTRODUÇÃO: A deformidade tuberosa da mama é uma rara entidade, descrita por Rees e Aston em 1976. O desenvolvimento mamário encontra-se alterado, com herniação do parênquima pelo complexo areolopapilar, alargamento dessa estrutura e hipoplasia do tecido mamário, principalmente nos quadrantes inferiores. A mama, portanto, adquire um aspecto tubular ao invés do aspecto cônico natural. MÉTODO: No total, 4 pacientes foram submetidas a tratamento cirúrgico em um único tempo, com incisões combinadas: inframamária e periareolar. Detalhes técnicos devem ser individualizados para cada caso, conforme a gravidade e a classificação do tipo de mama tuberosa. RESULTADOS: O procedimento cirúrgico utilizado aborda todos os aspectos da deformidade da mama tuberosa em operação de um estágio. Cirurgia de revisão de cicatriz periareolar não foi necessária em nenhum caso. Em todos os casos, obteve-se resultado estético final aceitável e com satisfação da paciente e do cirurgião. O procedimento adotado não interfere em lactações futuras. CONCLUSÕES: A mama tuberosa representa um verdadeiro desafio terapêutico. A técnica utilizada é muito atraente e mostra resultados confiáveis e reprodutíveis.

BACKGROUND: Tuberous breast deformity is a rare entity, first described by Rees and Aston in 1976. In this condition, breast development is altered, with herniation of the parenchyma through the nipple-areolar complex, enlargement of this structure, and hypoplasia of the breast tissue, especially in the lower quadrants. The breast thus acquires a tubular shape rather than the natural conical look. METHODS: Four patients underwent a single surgical treatment, with combined inframammary and periareolar incisions. Technical details must be individualized for each case depending on the severity and classification type of the tuberous breasts. RESULTS: The surgical procedure used covers all aspects of tuberous breast deformity in a single-stage operation. Revision of periareolar surgery scar was not necessary in any case. In all cases, the final aesthetic result was satisfactory for the patient and the surgeon. The procedure adopted does not interfere with future lactation. CONCLUSIONS: Tuberous breast represents a real therapeutic challenge. The technique reported herein is very attractive and provides reliable and reproducible results.
