Gastric band with jejunoileal by-pass: new option in bariatric surgery

BACKGROUND: Current procedures for surgical treatment of morbid obesity have proved to be efficient in controlling the process in the short and long follow-up. The bariatric surgical procedures, with the exception of the adjustable gastric banding are capable, in one way or another, of inducing hormonal release due to the intestinal by-pass that they may promote and therefore offering a metabolic effect. AIM: With the intention to maintain the same results promoted by gastrojejunal diversion, while maintaining the lower mortality rates of the adjustable gastric banding technique, it is proposed a new procedure combining adjustable gastric banding with jejunoileal diversion. METHOD: The surgical procedure, performed completely through videolaparoscopy, consisted of the initial application of the adjustable gastric banding and then a jejunoileal laterolateral by-pass, 80 cm from the duodenojejunal angle, with the distal ileum, at 120 cm from the ileocecal valve. RESULTS: Ten patients were operated on, six women and four men, with mean BMI of 40 kg/m². The average percentage of excess weight loss after the first six months was 51.56%. In four diabetic type II patients there was a normalization of glicemic and HbA1c levels with suspension of insulin and/or antidiabetic medications. CONCLUSION: The addition of a laparoscopic jejunoileal laterolateral by-pass to the adjustable gastric banding may enhance the efficacy of weight-loss and diabetes type II control in the treatment of morbid obesity and its resulting co-morbidities.
