Application of an improved continuous single-layer pancreaticojejunostomy technique in laparoscopic...

Laparoscopic pancreaticoduodenectomy (LPD) is a minimally invasive approach for pancreatic head and ampullary tumours, with pancreaticojejunostomy (PJ) critically influencing post-operative outcomes. This study aimed to compare a modified continuous single-layer PJ technique with the conventional two-layer method in LPD. A retrospective cohort study of 22 patients undergoing LPD compared the surgical outcomes between the modified group ( n = 12) and the conventional group ( n = 10). Baseline characteristics were well-matched between the two groups. The modified group demonstrated significantly shorter anastomosis time (19.08 vs. 23.1 min, P < 0.001) and lower abdominal infection rates (0 vs. 3 cases, P = 0.041). No significant differences were observed in clinically relevant post-operative pancreatic fistula or bleeding. Conclusively, the modified continuous single-layer PJ technique appears safe and feasible, offering efficiency advantages without compromising short-term outcomes. However, large-scale randomised controlled trials are warranted to validate safety, efficacy and long-term prognostic implications.
