Abstract
How to reduce grade C postoperative pancreatic fistula (POPF) incidence after pancreaticoduodenectomy (PD) is the pursuit of pancreatic surgeons. This study introduced an innovative pancreaticojejunostomy (PJ) technique with a complete set of perioperative management. All 144 patients in this single-center retrospective cohort study underwent the same PJ technique and perioperative management. The primary endpoint was grade C POPF incidence. The secondary endpoints were grade B POPF rate, drain fluid amylase level, complications, hospital stay duration, and mortality. Risk factors for clinically-relevant POPF (CR-POPF) were assessed by logistic regression analysis. No patient (0.0%) experienced grade C POPF, while 44 (30.6%) developed grade B. No in-hospital death was recorded. Multivariate analysis found relatively high body mass index, laparoscopic surgery, and soft or moderate pancreatic texture independent risk factors for CR-POPF. Our novel PJ anastomosis with modified perioperative management helped avoid grade C POPF. However, grade B POPF incidence was relatively high to some extent because of the enhanced management itself.
