Mini-Gastric Bypass: Description of the Technique and Preliminary Results

BACKGROUND: In recent years, a surgical technique known as single-anastomosis gastric bypass or mini-gastric bypass has been developed. Its frequency of performance has increased considerably in the current decade. AIM: To describe the mini-gastric bypass technique, its implementation and preliminary results in a university hospital. METHODS: This is an ongoing prospective trial to evaluate the long-term effects of mini-gastric bypass. The main features of the operation were: a gastric pouch with about 15-18 cm (50-150 ml) with a gastroenteric anastomosis in the pre-colic isoperistaltic loop 200 cm from the duodenojejunal angle (biliopancreatic loop). RESULTS: Seventeen individuals have undergone surgery. No procedure needed to be converted to open approach. The overall 30-day morbidity was 5.9% (one individual had intestinal obstruction caused by adhesions). There was no mortality. CONCLUSION: Mini-gastric bypass is a feasible and safe bariatric surgical procedure.
