BACKGROUND: Early @entity7623 is a frequent complication of pylorus-preserving pancreatoduodenectomy (PPPD). However, few reports have addressed this phenomenon in relation to the type of @entity344 . We compared gastrointestinal motility and gastric juice output after two different types of @entity344 following PPPD, end-to-side duodenojejunostomy after pancreaticojejunostomy and hepaticojejunostomy (group 1) and end-to-end duodenojejunostomy before pancreaticojejunostomy and hepaticojejunostomy (group 2). METHOD: In a total of 25 @entity1 , 10 in group 1 and 15 in group 2, who underwent PPPD, manometry was repeated to assess gastric and jejunal motility until the first occurrence of phase III activity of gastric cyclic motor activity (CMA). The plasma level of @entity3771 was measured in each phase of the gastric CMA and compared between the two groups. The daily volume of gastric juice output through a @entity5274 was also recorded for comparison. RESULT: There was no significant difference in the time period for recovery of gastric phase III activity and gastric juice output between the two groups. However, abnormal contractions with an increased basal pressure appeared frequently in the afferent jejunal loop only in group 1. The plasma @entity3771 level after PPPD showed no apparent cyclic change even after the recovery of gastric phase III in either group. CONCLUSION: Gastrointestinal reconstructive procedures have almost no effect on the recovery of gastric CMA. The plasma @entity3771 concentration does not play a major role in the recovery of gastric CMA in the early postoperative period after PPPD.
