摘要
Pancreaticoduodenectomy(PD)is performed for patients with tumors located in the region of the head of the pancreas,including cancer of the head of the pancreas,periampullary cancer,and distal bile duct cancer.PD is considered one of the most difficult and invasive surgeries in hepato-biliary-pancreatic surgeries because it requires meticulous techniques both in resection and reconstruction.Moreover,postoperative complications such as postoperative pancreatic fistula(POPF)and delayed gastric emptying(DGE)sometimes occur after PD,which leads to relatively higher mortality and longer postoperative hospital stay compared with other digestive surgeries.In PD,laparoscopic and robotic surgeries,called minimally invasive surgery(MIS),have recently been introduced.However,the incidence of postoperative complications and the length of the postoperative hospital stay have not decreased significantly after the introduction of such MIS(1-3).
