Abstract:
:Recently, CT scans have proved to be useful in revealing the site, level, and cause of bowel obstruction and in displaying signs of threatened bowel viability. This article outlines the utility of CT scans, both in terms of the diagnostic features of bowel obstruction and in the evaluation of its accuracy.
