Simplified Laparoscopic Gastric Bypass with Gastrojejunal Linear Mechanical Anastomosis: Technical Aspects
نویسندگان
چکیده
Background: Gastric bypass is a restrictive and malabsorptive surgery. The restrictive part consists in the creation of a small gastric pouch. The gastrointestinal bypass serves as the malabsorptive element. Aim: To describe a simplified gastric bypass approach for morbid obese patients, showing our results, and also remarking the importance of this technique for reducing the learning curve. Method: The patient is positioned in a split legs position and carefully strapped to the operating room table, with the surgeon between the patient's legs. Five trocars are inserted after pneumoperitoneum at the umbilicus. Dissection of the esophagogastric angle and lesser curvature is mandatory before the gastric pouch manufacturing. This pouch is done with two blue load staplers. Using a blue load linear stapler inserted only half way into the hole in the pouch is used to perform the gastrojejunal anastomosis and in order to create an anastomosis that is about 2 cm in length. A side-to-side jejunojejunostomy is done with a white load linear stapler. The last step of the gastric bypass consists in the cut of the jejunum between the two anastomosis with a white load linear stapler. Blue test is performed in order to detect leaks. Results: From January 2012 to December 2015, 415 simplified RYGB were performed. Gender: 67% female and 33 % males. Average of BMI 44.7. Mean age was 42 years old. Mean operative time 79 min. 39 % of this sample had T2 diabetes. Regarding complications were observed, one fistula, one gastrojejunal stenosis and one obstruction due to a bezoar. Conclusion: The described technique is a simplified approach in which all the anastomosis are performed in the upper part of the abdomen, allowing the surgeons to be more systematized and avoiding them to make mistakes in the confection of the Roux-en-Y anastomosis. This simplified gastric bypass is a safe and reproducible technique. Racional: Bypass gástrico é cirurgia restritiva e malabsortiva. A parte restritiva consiste na criação de uma pequena bolsa gástrica. O bypass gastrointestinal serve como o elemento malabsortivo. Objetivo: Descrever uma abordagem de bypass gástrico simplificado para pacientes obesos mórbidos, mostrando os resultados, e também destacando a importância desta técnica para reduzir a curva de aprendizagem. Método: O paciente é posicionado em posição de pernas abertas e cuidadosamente amarrado à mesa da sala de operação com o cirurgião entre as pernas. Cinco trocárteres são inseridos após pneumoperitônio no umbigo. Dissecção do ângulo esofagogástrico e curvatura menor é obrigatória antes da realização da bolsa gástrica. Esta bolsa é feita com dois grampeadores de carga azuis. Usando um grampeador carga linear azul inserido apenas a meio caminho para dentro do orifício na bolsa é executada a anastomose gastrojejunal a fim de criar anastomose de cerca de 2 cm de comprimento. Jejunojejunostomia laretolateral é feita com um grampeador carga linear branca. A última etapa do bypass gástrico consiste no corte do jejuno entre as duas anastomoses com um grampeador carga linear branco. Teste de azul é realizado de modo a detectar vazamentos. Resultados: De janeiro de 2012 a dezembro de 2015, foram realizadas 415 RYGB simplificadas. Gênero: 67% homens e 33% mulheres. A média do IMC foi de 44,7 e a de idade 42 anos. A média de tempo operatório foi de 79 min. 39% desta amostra tinha diabete melito tipo 2. Quanto às complicações foram observadas uma fístula, uma estenose gastrojejunal e uma obstrução devido à bezoar. Conclusão: A técnica descrita é uma abordagem simplificada, na qual todas as anastomoses são realizadas na parte superior do abdome, permitindo aos cirurgiões serem mais sistematizados e evitando cometerem erros na confecção da anastomose em Y-de-Roux. Este bypass gástrico simplificado é técnica segura e reprodutível.
