Factors Influencing Delayed Gastric Emptying After Pylorus-Preserving Pancreatoduodenectomy

Abstract

Preoperative cholangitis and postoperative leakage problems affect gastric emptying after PPPD during the early postoperative period. The retromesenteric route is not recommended for pancreato- and biliary-enteric anastomosis. We speculate that retromesenteric passage of afferent jejunum can cause venous congestion and bowel edema, which can in turn retard the recovery of jejunal peristalsis at the duodenojejunostomy site resulting in disturbance from food passage.
