Pylorus-preserving pancreatoduodenectomy:Influence of a Billroth I versus a Billroth II type of reconstruction on gastric emptying

Background/Aim: Delayed gastric emptying (DGE) is a frequent problem after pylorus-preserving pancreatoduodenectomy. Important risk factors are the presence of intra-abdominal complications. Searching for other causes, this study evaluates the influence of the type of reconstruction after a pancreatoduodenectomy (Billroth I vs. Billroth II; B I vs. B II on DGE. Methods: A retrospective study was performed evaluating consecutive patients from two surgical institutes. 174 patients were included (B II type of reconstruction n=123, period 1992-1996; B I type of reconstruction n=51, period 1988-1998). DGE was defined by gastric stasis requiring nasogastric intubation for 10 days or more or the inability to tolerate a regular diet on or before the 14th postoperative day. Results: After a B I type of reconstruction, there was significantly longer nasogastric intubation period as compared with a B II type of reconstruction (B I median 13 days, range 4-47, B II median 6 days, range 1-40; p
