Enteroclysis, the infusion of contrast medium directly into the small bowel, is a precise, rapid method for thorough small bowel examination. This technique demonstrates far more pathology than any other method when it is properly executed. However, the examination is sure to fail with poor techniques, thereby discrediting a superb method. Experience has shown that failures are usually due to inadequate technique or poor judgment or both during the examination. This article covers the proper and improper techniques of the examination and gives examples of each. The most common problems that arise during the examination are discussed in the order in which they usually develop.
The transnasal and peroral intubation routes for enteroclysis examination are described. A survey of 22 patients who underwent enteroclysis by both approaches revealed an overwhelming preference for the transnasal route. Transnasal intubation for enteroclysis is rapidly performed with adequate catheter control and in most patients is associated with less discomfort compared with the peroral route.
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.
