Laparoscopic biliopancreatic diversion: our preliminary experience with 201 consecutive cases.

Surgery as a treatment modality for morbid obesity has shown impressive progress over the past decades because of a better understanding of the metabolic characteristics of obesity and the rationale for its surgical treatment. Biliopancreatic diversion was first performed in humans in 1976. Since then it has been an excellent operation for morbid obesity to achieve long-term weight reduction. We present our laparoscopic biliopancreatic diversion protocol, with or without distal gastrectomy (Resa's operation). From 1995 to October 2008 we operated on 201 patients; open biliopancreatic diversion was performed in 48 patients, while the remaining patients underwent laparoscopic biliopancreatic diversion (84 laparoscopic Scopinaro's operations, 69 laparoscopic Resa's operations). The mean operating time was 140 minutes for the open procedures, 180 minutes for Scopinaro's laparoscopic operation and 135 minutes for Resa's laparoscopic operation. The mean postoperative stay was 5.5 days. Our mortality rate consisted of two patients (0.99%) who had pulmonary embolisms. Other major complications were three cases of leakage from the jejuno-ileal anastomosis, 18 cases of incisional hernia, 6 cases of metabolic diseases; 1 case of acute hepatitis and 1 case of bronchopneumonia. Biliopancreatic diversion can be performed satisfactorily by laparoscopy. A factor that may reduce the technical difficulties and make the technique totally reversible is the gastric sparing. Thus an upper digestive endoscopy can determine preoperatively whether the patient will need a gastrectomy, depending on its results.
