Complications Related to Gastric Bypass Performed with Different Gastrojejunal Diameters

چکیده
Background: Among the options for surgical treatment of obesity, the most widely used has been the Roux-en-Y gastric bypass. The gastrojejunal anastomosis can be accomplished in two ways: handsewn or using circular and linear stapled. The complications can be divided in early and late. Aim: To compare the incidence of early complications related with the handsewn gastrojejunal anastomosis in gastric bypass using Fouchet catheter with different diameters. Method: The records of 732 consecutive patients who had undergone the bypass were retrospectively analyzed and divided in two groups, group 1 with 12 mm anastomosis (n=374), and group 2 with 15 mm (n=358). Results: The groups showed anastomotic stenosis with rates of 11% and 3.1% respectively, with p=0.05. Other variables related to the anastomosis were also analyzed, but without statistical significance (p>0.05). Conclusion: The diameter of the anastomosis of 15 mm was related with lower incidence of stenosis. It was found that these patients had major bleeding postoperatively and lower surgical site infection, and in none was observed presence of anastomotic leak. Racional: Entre as opções para o tratamento cirúrgico da obesidade, o mais utilizado é o bypass gástrico em Y-de-Roux. A anastomose gastrojejunal dele pode ser realizada de duas maneiras, manualmente ou utilizando grampeador linear e circular, e as complicações são dividas em precoces e tardias. Objetivo: Comparar a incidência de complicações precoces relacionadas com a confecção manual da anastomose gastrojejunal no bypass gástrico utilizando sonda de Fouchet com calibres diferentes. Métodos: Foi realizada análise retrospectiva transversal com 732 pacientes submetidos ao procedimento, divididos em dois grupos, grupo 1 com anastomose de 12 mm (n=374), e grupo 2 de 15 mm (n=358). Resultados: Os grupos apresentaram taxas de estenose de anastomose de 11% e 3,1% respectivamente, com p=0,05. Outras variáveis relacionadas à anastomose também foram analisadas, porém sem significância estatística (p>0,05). Conclusão: O diâmetro da anastomose de 15 mm esteve relacionado à menor ocorrência de estenoses. Verificou-se, contudo, que estes pacientes apresentaram maior sangramento no pós-operatório e menor infecção de sítio cirúrgico. Não ocorreram fístulas na presente casuística.
