Pancreaticoduodenectomy (whipple procedure) is the standard operation for tumors of the pancreatic head, uncinate process, distal common bile duct as well as the papilla of vater. For reconstruction, pylorus-preservation (PPPD) has been shown to be technically and oncologically equivalent to the traditional whipple operation. One issue with this technique is delayed gastric emptying (DGE), which occurs in 25-70% of patients, usually emerging between day 4 and 14 after surgery. Patients with severe DGE can not only experience prolonged length of hospital stay, but are also at increased risk for other complications like aspiration or other issues related to the inability to ingest nutrition.
There is vast retrospective evidence and one prospective study indicating that antecolic reconstruction of the duodenojejunostomy can improve the rate and severity of delayed gastric emptying.
The investigators have conducted a prospective randomized trial in order to test this hypothesis. Patients were randomized to either undergo antecolic or retrocolic reconstruction after PPPD. On day 10 after surgery, DGE was assessed by clinical criteria. In addition, a test meal including 1g paracetamol was administered to check for clinically inapparent DGE. Of these serum samples, kinetics of intestinal peptides like GLP-1, PYY and glucagon was alos measured.

Delayed gastric emptying
Gastric emptying will be assessed by clinical criteria on postoperative day 10 after pylorus-preserving pancreatico-duodenectomy.
Time frame: Postoperative day 10
Paracetamol reabsorption test
On day 10 after pylorus-preserving pancreaticoduodenectomy, a test meal of a commercially available dietary product (Fresubin protein energy(c)) and 1g paracetamol will be administered. Serum levels of paracetamol will be measured at 0, 15, 30, 60 and 90 minutes after administration.
Time frame: postoperative day 10
Measurement of plasma intestinal peptides
On day 10 after pylorus-preserving pancreaticoduodenectomy, a test meal of a commercially available dietary product (Fresubin protein energy(c)) and 1g paracetamol will be administered. Serum levels of glucagon-like peptide-1 (GLP-1), peptide YY (PYY) and Glucagon will be measured at 0, 15, 30, 60 and 90 minutes after administration.
Time frame: postoperative day 10
