Abstract

Background/Aims: With the concept of less invasive surgery, PpPD (pylorus-preserving pancreatoduodenectomy) has taken the place of conventional Whipple pancreatoduodenectomy (Whipple) as a standard operation for pancreatic head carcinoma. The aim of this paper is to compare early and late postoperative results of PpPD and Whipple for pancreatic head carcinoma. Methodology: Postoperative clinical follow-up data and outcome of 50 Japanese patients with pancreatic head carcinoma who underwent pancreatoduodenectomy with or without pylorus preservation were reviewed to scrutinize the demerits and merits of the pylorus preservation. Results: Preoperative and postoperative serum chemistry was not different between the two groups. Mean operation time of the Whipple group was 517 minutes, which was significantly shorter than 624 minutes of the PpPD group (P=0.0006). Cumulative stage was not different between the two groups. Cumulative curability of the PpPD group was superior to the Whipple group; of the 27 patients with Whipple, A in 4, B in 5 and C in 18, while of the 23 patients with PpPD, A in 12, B in 2 and C in 9 (P=0.0182). Gastric tube was removed on POD 6.0 in the Whipple group, while on POD 39 in the PpPD group (P<0.0001). Oral intake was started on POD 14.0 in the Whipple group, while on POD 28.3 in the PpPD group (P=0.0018). Discharge was on POD 57.8 in the Whipple group, while POD 86.9 in the PpPD group (P=0.0023). At the time of discharge and postoperative 6, 12, and 18 months, body weight loss from the preoperative level was 1kg smaller in the PpPD group than in the Whipple group. 1-year and 3-year survival rates of the Whipple group was 53.8% and 15.8%, while 62.8% and 19.6% of the PpPD group, showing no significant difference. Conclusions: These data show that delayed gastric emptying is evident in the PpPD group, resulting in longer hospital stay, while long-term body weight loss is smaller in this group. The clinical outcome is similar between the two groups. PpPD can be accepted as a standard operation for pancreatic head carcinoma.
