BACKGROUND/AIMS: The gastrointestinal symptoms accompanying dysfunction of the remnant stomach were seen after pylorus-preserving operation. Against such complications, Dai-kenchu-to (DKT) is used, but scientific evidences for efficacy are poor. The effect of DKT on gastrointestinal motility and gastric emptying after pylorus-preserving operation was investigated.
METHODS: Using beagle dogs, the experimental models mimicking the state after pylorus-preserving pancreaticoduodenectomy were prepared. We sutured strain gauge transducers to the stomach, duodenum and jejunum and inserted indwelling tubes into the stomach. About 4 weeks after operation, DKT 0.1g/kg was administered during the fasting or fed state. At the same time, the gastric emptying was evaluated by the acetoaminophene method.
RESULTS: In the fasting state, administration of DKT enhanced the gastrointestinal motility and accelerated gastric emptying. In the postprandial state, no apparent effect on motility was seen.
CONCLUSION: DKT enhances the gastrointestinal motility after pylorus-preserving pancreaticoduodenectomy in the fasting state. The effect of DKT may not be related to the continuity of the intramural nerve.
