Abstract
IntroductionGastric bypass is today the most frequently performed bariatric procedure, but, despite of it, several complications can occur with varied morbimortality. Probably all bariatric surgeons know these complications, but, as bariatric surgery continues to spread, general surgeon must be familiarized to it and its management. Gastric bypass complications can be divided into two groups: early and late complications, taking into account the two weeks period after the surgery. This paper will focus the late ones.MethodLiterature review was carried out using Medline/PubMed, Cochrane Library, SciELO, and additional information on institutional sites of interest crossing the headings: gastric bypass AND complications; follow-up studies AND complications; postoperative complications AND anastomosis, Roux-en-Y; obesity AND postoperative complications. Search language was English.ResultsThere were selected 35 studies that matched the headings. Late complications were considered as: anastomotic strictures, marginal ulceration and gastrogastric fistula.ConclusionKnowledge on strategies on how to reduce the risk and incidence of complications must be acquired, and every surgeon must be familiar with these complications in order to achieve an earlier recognition and perform the best intervention.
Highlights
Among all the bariatric procedures, the gastric bypass is the most frequently performed[16]
Literature review was carried out using Medline/PubMed, Cochrane Library, SciELO, and additional information on institutional sites of interest crossing the headings: gastric bypass AND complications; follow-up studies AND complications; postoperative complications AND anastomosis, Roux-en-Y; obesity AND postoperative complications
Circular staplers offer surgeons a reproducible anastomosis, which eliminates any technique-dependent variability that might make it difficult to scientifically assess the effect of anastomotic size on incidence of stenosis and on the eventual weight loss resulting from gastric bypass surgery
Summary
Gastric bypass complications can be divided into two groups: early and late complications, taking into account the two weeks period after the surgery. Method: Literature review was carried out using Medline/PubMed, Cochrane Library, SciELO, and additional information on institutional sites of interest crossing the headings: gastric bypass AND complications; follow-up studies AND complications; postoperative complications AND anastomosis, Rouxen-Y; obesity AND postoperative complications. RESUMO - Introdução: O bypass gástrico é hoje o procedimento bariátrico mais realizado, mas, apesar disso, várias complicações podem ocorrer com variada morbimortalidade. Método: Foi realizada revisão da literatura utilizando as bases Medline/PubMed, Cochrane Library, SciELO, e informações adicionais sobre sites institucionais de interesse cruzando os descritores: bypass gástrico AND complicações; seguimento AND complicações; complicações pós-operatórias AND anastomose, Roux-en-Y; obesidade AND complicações pós-operatórias. As complicações tardias foram consideradas como: estenose de anastomose, ulceração marginal e fístula gastrogástrica. Conclusão: O conhecimento sobre as estratégias de como reduzir o risco e incidência das complicações deve ser adquirido ao longo do tempo, e cada cirurgião deve estar familiarizado com essas complicações, a fim de reconhecê-las precocemente e realizar a melhor intervenção
