A new reconstruction method for preventing delayed gastric emptying after pylorus-preserving pancreatoduodenectomy

Background With the aim of preventing delayed gastric emptying after pylorus-preserving pancreatoduodenectomy (PPPD), we devised a new reconstruction method in which the pancreas and the bile duct are anastomosed to the proximal jejunum brought through the transverse mesocolon, and the duodenum is antecolically anastomosed to the jejunum below the mesocolon. The right gastric artery is divided in order to place the stomach, the duodenum, and the jejunum in a straight line. Methods Thirty patients underwent PPPD with the new reconstruction method (n = 12) or the conventional method (all anastomoses performed retrocolically; N = 18). Early and late complications were compared between the two groups. Results Delayed gastric emptying occurred respectively in 1 patient (8%) and 13 patients (72%) operated on by the new and conventional method (P <0.001). The incidences of other complications did not differ significantly between the two groups. Conclusions The new reconstruction method may prevent delayed gastric emptying after PPPD.
