Comparison of recovery of gastric phase III motility and gastric juice output after different types of gastrointestinal reconstruction following pylorus-preserving pancreatoduodenectomy

Background: Early gastric stasis is a frequent complication of pylorus-preserving pancreatoduodenectomy (PPPD). However, few reports have addressed this phenomenon in relation to the type of gastrointestinal reconstruction. We compared gastrointestinal motility and gastric juice output after two different types of gastrointestinal reconstruction following PPPD, end-to-side duodenojejunostomy after pancreaticojejunostomy and hepaticojejunostomy (group 1) and end-to-end duodenojejunostomy before pancreaticojejunostomy and hepaticojejunostomy (group 2).
