Device assisted enteroscopy involves the use of a tube over the enteroscope to aid the insertion. DBE, Double-balloon enteroscopy; SBE, single-balloon enteroscopy. By compressing the walls, the gastroenterologist can reach and treat less accessible areas. Single balloon assisted enteroscopy (SBE) is an examination of the lining of the esophagus, stomach, and deep small intestine (duodenum, jejunum and ileum) with a small camera (flexible endoscope) which is inserted down the throat with the assistance of an overtube/balloon system (see image). The balloons are used during the test to anchor the endoscope in the digestive tract. On the tip of the overtube is a balloon that can be blown up and deflated. 6 : 2015 www.giejournal.org. There are 2 types of balloon enteroscopies: upper GI balloon enteroscopy (antegrade) and lower GI balloon enteroscopy (retrograde). The enteroscopy may be done as an inpatient or outpatient procedure. The overtube has a balloon on the tip that is used to anchor the overtube so that the endoscope can be advanced further into the small intestine. For single balloon endoscopy, a 200 cm long flexible, fiberoptic, endoscope (a hose-like tube one centimeter in diameter with a light and a camera on the tip) is fitted with an equally long overtube that slides the full length of the endoscope. Push enteroscopy became established in the 1980s, but it only allows a limited depth of penetration into the small bowel. Balloon-assisted enteroscopy uses endoscopes equipped with balloons that inflate and deflate to pinch together the walls of the GI tract. Starting with the introduction of the double-balloon enteroscope in 2001, two more techniques have been successfully developed for small bowel investigation (single-balloon enteroscopy, spiral enteroscopy). To compare the different enteroscopy systems, within this review, 68 studies were analyzed and put into context. Enteroscopy 976 GASTROINTESTINAL ENDOSCOPY Volume 82, No.

Deep enteroscopy platforms, including single balloon, double balloon, and spiral enteroscopy, were developed to allow access to the distal small bowel. Some enteroscopes have latex balloons in them and are used for double-balloon enteroscopy (DBE) or single-balloon enteroscopy (SBE). A single balloon enteroscopy allows the gastroenterologist to see images of the patient’s small intestine, in real time. There are two types of balloon assisted enteroscopy systems: the Double Balloon Enteroscopy (DBE) system, which uses two balloons; and the Single Balloon Enteroscopy (SBE) system which employs only a single balloon. Single balloon assisted enteroscopy (SBE) is an examination of the lining of the esophagus, stomach, and deep small intestine (duodenum, jejunum and ileum) with a small camera (flexible endoscope) which is inserted down the throat with the assistance of an overtube/balloon system (see image). On the tip of the overtube is … This tube either uses balloons (single balloon, double balloon) or a corkscrew (spiral). All of these technologies are similar in that they rely on an overtube system to allow deeper endoscope insertion. diameter (EN-450P5/20) and shorter length (EC-450BI5) are detailed in Table 1. Upon checking in, you will be escorted to the “pre-op” area where an IV will be placed and nurses will take down your medical information. At this time, you will also meet with an anesthesiologist to discuss the sedation used for the procedure. Enteroscopy is also known as a: double balloon enteroscopy; double bubble; capsule enteroscopy; push-and-pull enteroscopy; The two types of enteroscopy are upper and lower. Single-balloon enteroscopy, such as DBE, allow the possibility of suction and flushing via the instrument channel, sampling biopsies, and therapeutic interventions such as argon plasma coagulation, injection, positioning of clips, polypectomy, dilation, and foreign-body extraction, even when inserted distally into the small intestine.
