Enteroscopy is a procedure that is used to diagnose and treat problems in the digestive system. During this procedure, a flexible and thin tube along with an attached camera is inserted into the body. This tube is also known as an endoscope, and it has one or two balloons attached to it. Through this procedure, the surgeon can get a clear view of the stomach, esophagus and a section of the small intestine. Furthermore, scissors or forceps are used for the removal of tissue samples for analysis. Enteroscopy is also known as double balloon enteroscopy, push-and-pull enteroscopy, double bubble, and capsule enteroscopy. In case of upper enteroscopy, the surgeon inserts the endoscope into the mouth. Lower enteroscopy involves the insertion of an endoscope into the rectum. Depending on the type of problem to be diagnosed, the doctor chooses the enteroscopy method. Furthermore, balloon-assisted or deep enteroscopy allows both diagnoses as well as therapy. The therapies include dilation of strictures, treatment of bleeding lesions, a biopsy of abnormal tissue, removal of polyps and removal of foreign objects.
