Objective : We evaluated the applications, usefulness, and potential of double-balloon enteroscopy as a new therapeutic approach.
Object and Method : Fifty-six patients treated at Urayasu Ichikawa City Hospital between June 2004 and July 2005 were selected (M : F sex ratio 39 : 32, mean age 58.3 years). The 71 patients presented with gastrointestinal bleeding and/or positive fecal occult blood test or abdominal pain. However, there was no lesion causing hemorrhage detected on either upper or lower gastrointestinal endoscopy. Reasons for the examination were as follows : 49 cases of positive fecal occult blood test and melena, 21 cases of abdominal pain, and 1 case receivins stent placement.
Results : In 55 cases (78.6%), we successfully performed total enteroscopy. Of the 49 melena cases, angiodysplasia was the most common lesion detected (26 cases=53.1%), and ileal ulcers (6 cases), polyps (3), Meckel diverticulum (2), gastric ulcer (1), jejunal stromal tumor (1), and Crohn's disease (1) were also detected. In nine cases, there were no culprit lesions detected. In all 26 cases of angiodysplasia (64 lesions), hemostatic therapy was successful, and there was no recurrence during the two-to thirteen-month observation periods. In five of the twenty-one abdominal pain cases, inflammatory small bowel disease, and in two cases, ileal ulcers were detected. However, there were no lesions found in the remaining fourteen cases. The only case receiving stent placement was an inoperable case of advanced colorectal cancer in the ascending colon, and stent placement was performed relatively easily using the double-balloon method.
Conclusion : Double-balloon enteroscopy was useful for diagnosis of the small intestine lesion. With this method, hemostatic therapy and polypectomy were possible, and it also enabled endoscopic ultrasonography, balloon dilation, and stent placement in the deep colon. s
