Abstract

Patients undergoing pylorus-preserving pancreatoduodenenectomy (PPPD) have a risk of up to 50% for developing delayed gastric emptying (DGE) in the early postoperative course. From 1994 to August 2002, a total of 204 patients underwent PPPD for pancreatic or periampullary cancer (50%), chronic pancreatitis (42%), and other indications (8%). Retrocolic end-to-side duodenojejunostomy was performed below the mesocolon. DGE was defined by the inability to tolerate a regular diet after day 10 (DGE10) or day 14 (DGE14) postoperatively, as well as the need for a nasogastric tube at or beyond day 10 (DGE10GT). Postoperative morbidity was 38%, 30-day mortality was 2.9%, and median postoperative length of stay was 15 days. DGE occurred in 14.7% (DGE10), 5.9% (DGE14), and 6.4% (DGE10GT), respectively. After further exclusion of 21 patients (10.3%) with major complications and no possible oral intake (because of death, reoperation, or mechanical ventilation), the frequencies of DGE10, DGE14, and DGE10GT in the remaining group of 183 patients were 9%, 2%, and 2%, respectively. Multivariate analysis revealed postoperative complications (P<0.001), the presence of portalvenous hypertension (P<0.01), and tumors as indications for surgery (P<0.01) as independent risk factors for DGE10. The overall incidence of DGE was low after PPPD. In those patients experiencing DGE, however, other postoperative complications were the most important factor associated with its occurrence.
