Enteroscopy

Abstract

Wireless capsule endoscopy and double-balloon endoscopy are new methods of enteroscopy that have been introduced in recent years. Wireless capsule endoscopy is an epoch-making examination method that makes possible an endoscopic imaging examination of the entire small intestine without discomfort and without confining patients to a medical facility. Although it is expected to be useful as an initial examination for finding diseases of the small intestine, it cannot be used for biopsy or treatment. One risk associated with the capsule endoscopy technique is entrapment by strictures. Double-balloon endoscopy is based on a new insertion technique in which two balloons, one at the distal end of the endoscope and the other at the distal end of an overtube, are operated in combination, and the endoscope is inserted while simultaneously shortening the intestine. It can be inserted through either the mouth or the anus, allowing the observation of the entire gastrointestinal tract. It features excellent maneuverability even in the distal small intestine, and enables back-and-forth observation, biopsy, and endoscopic treatment at any given site. These two new enteroscopy techniques are expected to lead to innovations in how diseases of the small intestine are approached.

Role of intraoperative enteroscopy for surgical decision making with Crohn’s disease

“…These techniques include wireless videocapsule enteroscopy and small bowel enteroscopy [6,13,18,19,20]. Wireless videocapsule enteroscopy is minimally invasive and provides good diagnostic information in cases of CrohnÕs disease [6,18,19].…”

“…The reported incidence of capsule impaction is 2% to 5% [18,19]. Capsule enteroscopy is contraindicated when a stricture with a diameter less than 10 mm is present [19,20]. Double-balloon enteroscopy makes it possible to observe the whole length of the small intestine [20].…”

“…Capsule enteroscopy is contraindicated when a stricture with a diameter less than 10 mm is present [19,20]. Double-balloon enteroscopy makes it possible to observe the whole length of the small intestine [20]. However, the safety and efficacy of this new technique for patients who have CrohnÕs disease with severe and multiple strictures have not been studied sufficiently.…”

Enteroscopy-guided Contrast Radiography of Small Bowel Lesions

“…During the DBE procedure, ECR can be performed as well by occluding the bowel lumen with balloons to prevent reflux of the contrast media (11). In our experience, ECR can play an important role in the diagnosis and treatment of various small bowel diseases.…”

Efficacy of pediatric colonoscopy used as push enteroscopy in the management of capsule endoscopy findings

“…For many years this technique has been the most widely used and effective technique for the direct evaluation of the enteral mucosa. One of its limitations is that it can only be used to explore part of the jejunum, and, while it can reach more than 100 cm beyond the ligament of Treitz, a large part of the small intestine remains unexplored (2,5). Nevertheless, it does enable us to provide a diagnosis in a large number of patients with undi- agnosed gastrointestinal bleeding, and it gives us the opportunity to treat bleeding, especially in vascular lesions.…”
