The impact of pylorus-preserving pancreatoduodenectomy on surgical treatment for cancer of the pancreatic head

Abstract.

Pylorus-preserving pancreatoduodenectomy (PPPD) was reintroduced in 1978. This pylorus-preserving modification was designed to minimize complications related to gastric resection, such as early satiety, marginal ulceration, and bile reflux gastritis, as well as diarrhea and dumping. Since 1978, PPPD has been performed preferentially for benign and malignant diseases of the periampullary region and pancreatic head. Some groups have argued against PPPD for cancer of the pancreatic head, because the pylorus-preserving procedure is likely to compromise the field of resection and does not allow lymph node dissection of the peripyloric and perigastric groups. However, comparative survival rates after PPPD have been the same as, or better than, those with classic pancreatoduodenectomy, showing the rationale for PPPD as a radical resection procedure for cancer of the pancreatic head. PPPD can be performed with low mortality. Delayed gastric emptying, which is the most common complication in the immediate postoperative period after PPPD, is always transient. Many investigators have shown that body weight and the majority of nutritional parameters are better than after PD. PPPD does not appear to cause any negative outcomes. We conclude that PPPD is the surgical procedure of choice for cancer of the head of the pancreas.
