Q: What is the procedure called Enteroclysis?
Answer: Enteroclysis is a procedure utilized in non-acute mechanical small bowel obstruction (M-SBO). In procedure, nasojejunal (NJ) tube is passed in the duodenum, and a large volume of air and contrast is passed into the small intestine. The procedure is closely guided by fluoroscopy. Methylcellulose, in contrast, works as a volume challenge and accentuates the effect of low-grade obstruction. This procedure can be beneficial in patients with recurrent small bowel obstruction, as enteroclysis can identify the areas of stenosis.
