Abstract
Backgrounds : Delayed gastric emptying (DGE) is said to occur from ischemia of the pylorus and we always pay attention to the blood flow in the pylorus so as not to induce ischemia, when we perform pylorus-preserving pancreatoduodenectomy (PPPD). Methods : We enrolled 221 patients undergoing pancreatoduodenectomy in our hospital from January 2000 to April 2011. These patients were divided into two groups, 168 undergone PPPD and 53 undergone subtotal stomach-preserving pancreatoduodenectomy (SSPPD) and were comparatively evaluated for demographics of the patients, postoperative complications including DGE, removal of nasogastric catheter and start of oral intake. Results : A total of 44 patients (19.9%) developed DGE, including 32 patients (19.0%) of PPPD group and 12 patients (22.6%) of SSPPD group. There was no significant difference in frequency of DGE between two groups. Conclusions : In performing PPPD, much attention to the blood flow in the pylorus so as not to induce ischemia and congestion might result in the frequency of DGE that is not significantly different from that of SSPPD.
