The object of this study was to define the pattern of gastrointestinal myoelectrical activity before and after cholecystectomy. After surgery, on the first postoperative day, the mean and maximal activities of the gastrointestinal tracts decreased significantly, but there was no significant change in the pattern and the duration of the nonreactive period. A dyskinetic effect and/or weakness of electrical activity was observed in all patients before operation, and the same pattern persisted after operation for one month. This suggests the future onset of the so-called postcholecystectomy syndrome, which may result from the fundamental pathological effect of gallstones.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
