 Abstract
Backgrounds/Aims: Pancreaticoduodenectomy (PD) is associated with various surgical complications including healing failure of the pancreaticojejunostomy (PJ). This study intended to ensure blood supply to the pancreatic stump through extended pancreatic transection (EPT). Methods: This study assessed whether EPT reduces PJ-associated complica-tions and whether EPT is harmful on the remnant pancreatic function. The EPT group included 19 patients undergoing PD, pylorus-preserving PD (PPPD) or hepatopancreaticoduodenectomy. The propensity score matched control group included 45 patients who had undergone PPPD. Pancreatic transection was performed at the level of the celiac axis in the EPT group, by which the pancreatic body was additionally removed by 3 cm in length comparing with the conven-tional pancreatic transection. Results: A small invagination fissure suspected as the embryonic fusion site was identified at the ventro-caudal edge of the pancreatic body in all patients undergoing EPT. A sizable fissure permitting easy separation of the pancreatic parenchyma was identified in 15 of 19 patients (78.9%). The incidence of significant post-operative pancreatic fistula was significantly lower in the EPT group than in the control group (p=0.047). There was no significant increase in the postoperative de novo diabetes mellitus in EPT group (p=0.60). Conclusions: The EPT technique contributes to the prevention of major pancreatic fistula without impairing remnant pancreatic function. EPT is feasible for routine clinical application or at least in patients with any known risk of PJ leak. (Ann Hepatobiliary Pancreat Surg 2017;21:138-145)
