The advantages of pylorus-preserving pancreatoduodenectomy in malignant disease of the pancreas and periampullary region

The aim of this study was to establish whether the pylorus-preserving pancreatoduodenectomy (PPPD) is a safe and radical procedure in malignant disease of the head of the pancreas and periampullary region, without increased morbidity and mortality rates compared with the standard Whipple's procedure. During the period 1984 to 1990, a Whipple's procedure (n = 44) or PPPD (n = 47) was performed in 91 patients. In-hospital mortality rates were 2% after PPPD and 5% after Whipple's procedure. Median duration of the resection procedure and median blood loss in the PPPD group were 210 minutes and 1800 mL, respectively. After Whipple's procedure, these figures were 255 minutes and 2500 mL, both significantly different (p < 0.01) as compared with PPPD. No difference was found during follow-up with respect to days of gastric suctioning, start of liquid diet, normal diet, complaints of ulcer disease, postoperative complications, recurrence of disease, and survival. In all patients, curative resection was performed with comparable TNM (tumor, nodes, metastases) staging. The number of tumor-containing duodenal or gastric resection margins did not differ in both groups of patients (two patients after PPPD, two patients after Whipple's procedure). Hospital stay was significantly (p = 0.02) shorter after PPPD; median 14 days, compared with median 18 days after Whipple's procedure. The advantage of the PPPD is that it is an easier and less time-consuming operation, with less blood loss, a shorter hospital stay, and better weight gain (p = 0.02) during follow-up. In conclusion, PPPD is a safe and radical procedure for cancer in the head of the pancreas or periampullary region, with the same survival and appearance of locoregional recurrence and distant metastases as after standard Whipple's resection.
