Both capsule endoscopy (CE) and double balloon enteroscopy (DBE) are well establised as modalities to detect small bowel lesion. They are available for direct detection of NSAIDs induced small bowel enteropathy, or even for endoscopic treatment in latter. --> Non-Steroidal Anti-Inflammatory Drug-Induced Enteropathy by YJ Lim. Clin Endosc. 2012 Jun; 45(2): 138–144.
With the emerging of CT and MR enterography nowadays, certain centers may use CTE/MRE as routine diagnostic tests for patients with potential small bowel disorders and obscure gastrointestinal bleeding, as they are less invasive.--> Few studies had been published eg CT enteroclysis/enterography findings in drug-induced small-bowel damage by T Kishi. Br J Radiol. December 2014; 87(1044): 20140367. However, most of these studies are of small number of subjects. And mild damage of small bowel may not be detected by CTE.
Both CE and double balloon enteroscopy DBE are well establised as modalities to detect small bowel lesion.However, the most widely reported technique is CE. I have summarized the latest studies in the following review published in Translational research which might be useful.
