Predictive factors for short gastric vessels division during laparoscopic total fundoplication.

OBJECTIVE: to determine clinical variables that can predict the need for division of the short gastric vessels (SGV), based on the gastric fundus tension, assessing postoperative outcomes in patients submitted or not to section of these vessels. METHODS: we analyzed data from 399 consecutive patients undergoing laparoscopic fundoplication for gastroesophageal reflux disease (GERD). The section of the SGV was performed according to the surgeon evaluation, based on the fundus tension. Patients were divided into two groups: not requiring SGV section (group A) or requiring SGV section (group B). RESULTS: the section was not necessary in 364 (91%) patients (Group A) and required in 35 (9%) patients (Group B). Group B had proportionally more male patients and higher average height. The endoscopic parameters were worse for Group B, with larger hiatal hernias, greater hernias proportion with more than four centimeters, more intense esophagitis, higher proportion of Barrett's esophagus and long Barrett's esophagus. Male gender and grade IV-V esophagitis were considered independent predictors in the multivariate analysis. Transient dysphagia and GERD symptoms were more common in Group B. CONCLUSION: the division of the short gastric vessels is not required routinely, but male gender and grade IV-V esophagitis are independent predictors of the need for section of these vessels.

OBJETIVO: Determinar variáveis clínicas que possam predizer a necessidade de secção dos vasos gástricos curtos (VGC), baseado na tensão do fundo gástrico, avaliando os resultados pós-operatórios em pacientes submetidos ou não à secção destes vasos. MÉTODOS:Foram analisados os dados de 399 pacientes consecutivos submetidos à fundoplicatura total laparoscópica para a doença do refluxo gastroesofágico (DRGE). A secção dos VGC foi realizada de acordo com a avaliação do cirurgião, baseado na tensão do fundo gástrico. Os pacientes foram distribuídos em dois grupos: sem necessidade de secção dos VGC (grupo A) ou com necessidade de secção dos VGC (grupo B). RESULTADOS:A secção não foi necessária em 364 (91%) pacientes (Grupo A) e necessária em 35 (9%) pacientes (Grupo B). O Grupo B tinha proporcionalmente mais pacientes do sexo masculino e maior estatura média. Os parâmetros endoscópicos foram piores para o Grupo B, com maiores hérnias hiatais, maior proporção de hérnias com mais de quatro centímetros, esofagite mais intensa, maior proporção de esôfago de Barrett e esôfago de Barrett longo. O sexo masculino e as esofagites graus IV-V foram considerados fatores preditivos independentes na análise multivariada. A disfagia transitória e os sintomas de DRGE foram mais comuns no Grupo B. CONCLUSÃO:A secção dos vasos gástricos curtos não é necessária rotineiramente, porém o sexo masculino e as esofagites graus IV-V são fatores preditivos independentes da necessidade da secção destes vasos.

Dysphagia after laparoscopic total fundoplication: anterior or posterior gastric wall fundoplication?

CONTEXT: The occurrence of severe dysphagia after laparoscopic total fundoplication is currently an important factor associated with loss of quality of life in patients undergoing this modality of treatment for gastroesophageal reflux disease. OBJECTIVES: Compare the incidence and evaluate the causes of severe postoperative dysphagia in patients undergoing laparoscopic total fundoplication (LTF) without short gastric vessels division, using the anterior gastric wall (Rossetti LTF) or anterior and posterior gastric walls (Nissen LTF). METHODS: Analysis of the data of 289 patients submitted to LTF without short gastric vessels division from January 2004 to January 2012, with a minimum follow-up of 6 months. Patients were divided in Group 1 (Rossetti LTF - n = 160) and Group 2 (Nissen LTF - n = 129). RESULTS: The overall incidence of severe postoperative dysphagia was 3.11% (4.37% in group 1 and 1.55% in group 2; P = 0.169). The need for surgical treatment of dysphagia was 2.5% in group 1 and 0.78% in group 2 (= 0.264). Distortions of the fundoplication were identified as possible causes of the dysphagia in all patients taken to redo fundoplication after Rossetti LTF. No wrap distortion was seen in redo fundoplication after Nissen LTF. CONCLUSIONS: The overall incidence of severe postoperative dysphagia did not differ on the reported techniques. Only Rossetti LTF was associated with structural distortion of the fundoplication that could justify the dysphagia.

Contexto A ocorrência de disfagia grave após fundoplicatura total laparoscópica representa atualmente um importante fator associado à perda da qualidade de vida em pacientes submetidos a esta modalidade de tratamento para doença do refluxo gastroesofágico. Objetivos Comparar a incidência e avaliar as possíveis causas da disfagia grave pós-operatória em pacientes submetidos à fundoplicatura total laparoscópica (FTL) sem liberação dos vasos gástricos curtos utilizando apenas a parede gástrica anterior (FTL à Rossetti) ou as paredes gástricas anterior e posterior (FTL à Nissen). Métodos Análise de dados de 289 pacientes submetidos à FTL sem liberação dos vasos gástricos curtos no período de janeiro de 2004 a janeiro de 2012, com acompanhamento mínimo de 6 meses. Os pacientes foram divididos em Grupo 1 (FTL à Rossetti – n = 160) e Grupo 2 (FTL à Nissen – n = 129). Resultados A incidência global de disfagia grave pós-operatória foi de 3,11%, sendo 4,37% no grupo 1 e 1,55% no grupo 2 (P = 0.169). A necessidade de tratamento cirúrgico da disfagia foi de 2,5% no grupo 1 e 0,78% no grupo 2 (P = 0.264). Em todos os pacientes reoperados após FTL à Rossetti foram observadas distorções das válvulas que podem responder pela ocorrência de disfagia, ao passo que no paciente submetido à reoperação após FTL à Nissen nenhuma alteração foi observada. Conclusões A incidência global de disfagia grave pós-operatória não apresentou diferença entre as duas técnicas relatadas. A FTL à Rossetti foi associada a distorções estruturais das válvulas que podem justificar a disfagia, fato não observado após FTL à Nissen. .

Hepatectomia laparoscópica: indicações e resultados em 18 casos ressecados / Laparoscopic hepatectomy: indications and results from 18 resectable cases

Objective: To evaluate the early and late results from laparoscopic hepatectomy procedures at a tertiary hospital in Brasília (DF), Brazil. Methods: The authors report on a series of 18 patients (11 women) who underwent laparoscopic hepatectomy performed by a single surgical team at Santa Lúcia Hospital, in Brasília, between June 2007 and December 2010. Age ranged from 21 to 71 years (median = 43 years). There were eleven women and seven men. Nine patients had benign diseases and nine had malignant lesions. The lesion diameter ranged from 1.8 to 12 cm (mean: 4.96 cm). Results: Six major hepatectomy procedures and 12 minor hepatectomy procedures were performed. The mean duration of the operation was 205 minutes (range: 90 to 360 minutes). The mean intraoperative blood loss was 300 mL (range: 100 to 1,500 mL). Two patients received a transfusion (11%). There was one conversion to open surgery. There was no death and no patient underwent reoperation. The postoperative morbidity rate was 11% (n = 2). One patient presented with a minor complication (lobar pneumonia) while other presented with two major complications (intraoperative bleeding and incisional hernia). The median length of hospital stay was 4 days (range: 2 to 11 days). The median time to return to normal activities was 13 days (range: 7 to 40 days). Conclusion: Laparoscopic hepatectomy is a safe surgical approach for treating both benign and malignant hepatic lesions. This small series showed no mortality, low morbidity and good cosmetic results.

Objetivo: Avaliar os resultados precoces e tardios das hepatectomias laparoscópicas realizadas em um hospital terciário, em Brasília (DF). Métodos: Os autores relatam uma série de 18 pacientes (11 mulheres) submetidos à hepatectomia laparoscópica, realizada por uma única equipe cirúrgica do Hospital Santa Lúcia, em Brasília, entre Junho de 2007 e Dezembro de 2010. A idade variou de 21 a 71 anos com mediana de 43 anos. Havia onze mulheres e sete homens. Nove casos apresentavam lesão benigna e nove, lesão maligna. O diâmetro da lesão variou de 1,8 a 12 cm (média: 4,96 cm). Resultados: Seis hepatectomias maiores e 12 hepatectomias menores foram realizadas. O tempo cirúrgico médio foi de 205 minutos (variação de 90 a 360 minutos). A média de sangramento intraoperatório foi de 300 mL (variação de 100 a 1.500 mL). Dois pacientes foram transfundidos. Houve uma conversão para cirurgia aberta. Não houve óbitos e nenhum paciente foi reoperado. A morbidade pós-operatória foi de 11% (n = 2). Um indivíduo apresentou uma complicação menor (pneumonia lobar), e outro teve duas complicações maiores (sangramento intraoperatório e hérnia incisional). A duraçãomediana de internação foi de 4 dias (variação de 2 a 11 dias). O tempo mediano de retorno às atividades diárias foi de 13 dias (variação de 7 a 40 dias). Conclusão: A hepatectomia laparoscópica é um método cirúrgico seguro para tratamento de lesões hepáticas benignas e malignas. Nesta pequena série, não houve óbitos, a taxa de morbidade foi baixa, e o resultado estético foi bom.

A exenteração pélvica para o câncer de reto: avaliação dos fatores prognósticos de sobrevida em 27 pacientes operados / Pelvic exenteration from rectal cancer: evaluation of survival prognostic factors on 27 resectable cases

OBJETIVO: Identificar os fatores prognósticos de sobrevida dos pacientes submetidos à exenteração pélvica no tratamento curativo do câncer de reto (no Estádio T4 e na recidiva pélvica isolada). MÉTODOS: Os dados completos de 27 pacientes submetidos a esse tipo de operação por adenocarcinoma de reto entre Janeiro de 1996 a Junho de 2006 foram avaliados. Foram estudados diversos fatores prognósticos epidemiológicos, cirúrgicos e histológicos por meio de análise multivariada. RESULTADOS: A mortalidade pós-operatória foi de 7 por cento (n=2) enquanto a morbidade global foi de 55 por cento (n=15). A média de sobrevida global foi de 38 meses. A sobrevida global foi maior nos tumores T4 do que nas recidivas pélvicas (47 X 26 meses). Somente o comprometimento linfonodal (N+) foi fator prognóstico negativo na análise multivariada. CONCLUSÃO: A exenteração pélvica para o tratamento do câncer de reto apresenta alta morbidade e considerável mortalidade. Deve ser indicada nos tumores T4, principalmente quando não há disseminação linfonodal.

AIM: To identify survival prognostic factors in patients who underwent curative pelvic exenteration from rectal adenocarcinoma (T4 tumors and isolated pelvic recurrence). METHODS: Complete follow-up data were available on 27 patients who underwent this surgical procedure between 1996 and 2006. Multiple prognostic factors were studied by multivariate analysis (epidemiological, surgical and histological). RESULTS: Postoperative mortality was 7 percent (n=2) while overall morbidity was 55 percent (n=15). Mean of overall survival was 38 months. T4 tumors presented more long-time survival than pelvic recurrence (47 X 26 months). Lymph node disease (N+) was single adverse prognostic factor at multivariate analysis. CONCLUSION: Pelvic exenteration presents both high morbidity and considerable mortality. It should be reserved for T4 tumors, principally when there was no lymph node spreading.
