A Multicenter Randomized Controlled Study of External Pancreatic Duct Stents in Pancreaticoduodenectomy

All pancreaticoduodenectomies were performed by the same surgical team at our pancreatic center throughout the study period. According to the preoperative laboratory results, medical imaging data, and intraoperative conditions, the laparoscopic or open pancreaticoduodenectomy, or pylorus-preserving pancreaticoduodenectomy was performed at the discretion of the individual surgeon. The child's technique was implemented to achieve digestive tract reconstruction, and all patients underwent a duct-to-mucosa pancreaticojejunostomy. The external pancreatic duct stent left the other end exteriorized through the proximal jejunum via a small enterotomy that was fixed in the abdominal wall.

The internal pancreatic duct stent, a silicone catheter with multiple side pores, was inserted into the main pancreatic duct and the other end was placed in the jejunum cavity.
