RESUMO

OBJECTIVE: To study the recovery course of gastric emptying after Billroth I pylorus-preserving pancreatoduodenectomy (PPPD) and therapeutic effects of cisapride. METHODS: To examine gastric emptying, acetaminophen was given, admixed in a pasty liquid meal, to 16 patients undergoing PPPD before surgery and at 1, 3, 6, 9, and 12 months after surgery. Cisapride was given orally to 10 patients before they received the acetaminophen regimen. Electrogastrography was performed at 2 weeks to 1 month after surgery in eight patients and at 6 to 12 months after surgery in seven patients. RESULTS: Gastric emptying was delayed but returned to the preoperative level by 6 months after surgery. Pretreatment with cisapride accelerated gastric emptying during months 1 to 6 but not during months 6 to 12 after surgery. Electrogastrography frequently showed tachygastria 2 weeks to 1 month after surgery, but seldom 6 to 12 months after surgery. CONCLUSIONS: After Billroth I PPPD, gastric emptying is delayed but recovers by 6 months after surgery. Tachygastria may play a part in the pathogenesis of delayed gastric emptying, but it can be treated with cisapride.
