Laparoscopic pancreatoduodenctomy (LPD) may offer advantages over open pancreatoduodenectomy, including early postoperative mobilization, less delayed gastric emptying and a shorter hospital stay. However, LPD is technically challenging and not well-standardized, especially regarding the pancreatic anastomosis. We describe a standardized technique for the pancreatic anastomosis during LPD: modified Blumgart pancreaticojejunostomy.

Laparoscopic pancreatoduodenectomy (LPD) is a complex surgical procedure that may provide benefits over traditional open surgery, such as reduced recovery time and less postoperative complications. This article details a standardized technique for performing the pancreatic anastomosis during LPD using modified Blumgart pancreaticojejunostomy.
