- Abstract
This study investigated the effect of loperamide on the motor function of small intestine and J-pouch. Proctocolectomy and ileal pouch–anal anastomosis were performed in four dogs. Motility was recorded by serosal electrodes and strain gauge transducers. The intestinal transit time was determined radiologically. Multiple measurements were performed before and during chronic administration of loperamide. This treatment led to a significant decrease in median stool frequency from 11 (10–13) to 9 stools/day (8–12) and a tendential increase in intestinal transit time from 60 (50–105) to 70 min (60–90). This was not accompanied by significant changes in fasted or postprandial motility. There were no significant differences in the characteristics of the migrating myoelectric complex or in the fed pattern, either in the small intestine or in the pouch. Loperamide thus does not significantly affect intestinal motility after ileal pouch–anal anastomosis. The reduction in stool frequency seems to be due to antisecretory effects in the first line.
