A new approach to the fashioning of the gastroenteroanastomosis in laparoscopicstandard biliopancreatic diversion.

A retrocolic submesocolic approach was used for creating the gastroenteroanastomosis in 42 consecutive patients who underwent laparoscopic biliopancreatic diversion for obesity. The surgical technique is described in detail. The laparoscopic gastroenteroanastomosis was successfully performed on all the operated patients, with no intraoperative complications requiring conversion to open surgery and no immediate or late postoperative morbidity related to the anastomosis.
