Background: Minimally invasive techniques offer theoretical advantages for treating resectable periampullary neoplasms. Laparoscopic pancreaticoduodenectomy (LPD) was first reported in 1992 and has been performed clinically despite lack of animal data to support the operation. The purpose of this study was to develop LPD in an acute porcine model and to assess safety and efficacy before considering clinical trials. Methods: LPD was initiated in six domestic pigs under general anesthesia. Once pneumoperitoneum was created, five 10-mm access ports were placed (one central and two in each flank). After cholecystectomy, the duodenum was mobilized and the proximal jejunum was divided distal to the ligament of Treitz. The neck of the pancreas was separated from the superior mesenteric vein, and the midstomach was divided by a stapler. Pancreaticojejunostomy (PJ), choledochojejunostomy (CDJ), and gastrojejunostomy (GJ) were performed using interrupted sutures. The animals were immediately sacrificed and the operative site was examined. Results: LPD was aborted in three animals due to complications: intestinal perforation with fecal contamination (one) and prolonged resection time ≥ 2.5 h (two). LPD was completed in three animals (operative time ranged from 5.0 to 7.5 h, blood loss < 200 cc); however, at sacrifice one PJ and two CDJs had small posterior leaks. The efferent loop of the GJ was narrowed by the staple line in one pig. All animals had extensive ecchymosis of the jejunal serosa due to excessive manipulation. Conclusion: Despite a significant number of anastomotic leaks in the immediate postoperative period, laparoscopic pancreaticoduodenectomy is feasible in a porcine model. Further studies and technical development are necessary before laparoscopic pancreatic resection can be performed on a more widespread basis.
