OBJECTIVE: To analyze factors affecting the recovery course of phase 3 activity of the gastric migrating motor complex after pylorus-preserving pancreatoduodenectomy (PPPD) and investigate effects of the recovery of gastric phase 3 on gastric emptying after feeding.
SUMMARY BACKGROUND DATA: Whether early recovery of gastric phase 3 during fasting would predict early recovery of the fed-state gastric emptying function after PPPD has not been well documented.
METHODS: Manometric recording from the gastric antrum was repeated at a weekly interval until the first appearance of gastric phase 3 in 57 patients after PPPD. Twenty-three clinical parameters were assessed as possible factors affecting the recovery course of gastric phase 3 by simple and multiple regression analyses. A gastric emptying study after feeding of a test meal was performed by the acetaminophen method and the values were compared between patients with and without gastric phase 3 after PPPD.
RESULTS: The mean period before the first appearance of gastric phase 3 was 38 days. Among 23 parameters, only lymph node dissection along the hepatoduodenal ligament significantly delayed recovery of gastric phase 3 after PPPD by univariate and multivariate analyses. The presence or absence of gastric phase 3 in the early postoperative period did not influence gastric emptying after feeding in the intermediate period after PPPD.
CONCLUSIONS: Avoiding lymph node dissection along the hepatoduodenal ligament, if applicable, may contribute to early recovery of gastric phase 3 after PPPD. The recovery state of gastric phase 3 during fasting, however, is not necessarily consistent with the degree of improvement of gastric emptying after feeding.
