Deep enteroscopy allows for the diagnosis and treatment of small bowel disorders that historically required operative intervention. There are a variety of endoscopic platforms using balloons and rotational overtubes to facilitate small bowel intubation and even allow for total enteroscopy. Obscure gastrointestinal bleeding is the most common indication for deep enteroscopy. By visualizing segments of the small bowel not possible through standard EGD or push enteroscopy, deep enteroscopy has an established high rate of identification and treatment of bleeding sources. In addition to obscure bleeding, other common indications include diagnosis and staging of Crohn’s disease, evaluation of findings on capsule endoscopy and investigation of possible small bowel tumors. Large endoscopy databases have shown deep enteroscopy to be not only effective but safe. Recent research has focused on comparing the diagnostic rates, efficacy, and total enteroscopy rates of the different endoscopic platforms.
