RESUMEN
INTRODUCTION: Postoperative anastomotic leak and stricture are dramatic events that cause increased morbidity and mortality, for this reason it's important to evaluate which is the best way to perform the anastomosis. AIM: To compare the techniques of manual (hand-sewn) and mechanic (stapler) esophagogastric anastomosis after resection of malignant neoplasm of esophagus, as the occurrence of anastomotic leak, anastomotic stricture, blood loss, cardiac and pulmonary complications, mortality and surgical time. METHODS: A systematic review of randomized clinical trials, which included studies from four databases (Medline, Embase, Cochrane and Lilacs) using the combination of descriptors (anastomosis, surgical) and (esophagectomy) was performed. RESULTS: Thirteen randomized trials were included, totaling 1778 patients, 889 in the hand-sewn group and 889 in the stapler group. The stapler reduced bleeding (p <0.03) and operating time (p<0.00001) when compared to hand-sewn after esophageal resection. However, stapler increased the risk of anastomotic stricture (NNH=33), pulmonary complications (NNH=12) and mortality (NNH=33). There was no significant difference in relation to anastomotic leak (p=0.76) and cardiac complications (p=0.96). CONCLUSION: After resection of esophageal cancer, the use of stapler shown to reduce blood loss and surgical time, but increased the incidence of anastomotic stricture, pulmonary complications and mortality.

INTRODUÇÃO: Deiscências e estenoses anastomóticas pós-operatórias são eventos dramáticos que causam aumento da morbimortalidade; por esta razão é sempre importante avaliar qual é o melhor meio de se fazer as anastomoses. OBJETIVO: Comparar as técnicas de anastomose esofagogástrica manual e mecânica, após ressecção de neoplasia maligna de esôfago, quanto à ocorrência de fístula, estenose, sangramento, complicações cardíacas e pulmonares, mortalidade e tempo cirúrgico. MÉTODOS: Foi realizada uma revisão sistemática de ensaios clínicos randomizados, que incluiu estudos de quatro bases de dados (Medline, Embase, Cochrane e Lilacs) usando a combinação dos descritores (anastomosis, surgical) and (esophagectomy). RESULTADOS: Treze ensaios clínicos randomizados foram incluídos, totalizando 1778 pacientes, sendo 889 no grupo da anastomose manual e 889 no grupo da anastomose mecânica. A anastomose mecânica reduziu o sangramento (p<0,03) e o tempo cirúrgico (p<0,00001) quando comparado à anastomose manual pós ressecção esofágica. No entanto, a anastomose mecânica aumentou o risco de estenose (NNH=33), complicações pulmonares (NNH=12) e mortalidade (NNH=33). Não houve diferença significativa em relação à formação de fístulas (p=0,76) e complicações cardíacas (p=0,96). CONCLUSÃO: Após ressecção de neoplasia esofágica, o uso da anastomose mecânica demonstrou reduzir o sangramento e o tempo cirúrgico, porém aumentou a incidência de estenose, complicações pulmonares e mortalidade. .
