BackgroundThe diagnosis and treatment of small-bowel diseases is clinically difficult. The purpose of this study was to evaluate the diagnostic and therapeutic value of double-balloon enteroscopy in small-bowel diseases.MethodsThe history and outcomes of 2806 patients who underwent double-balloon enteroscopy from July 2004 to April 2017 were reviewed, which included 562 patients with obscure digestive tract bleeding, 457 patients with obscure diarrhea, 930 patients with obscure abdominal pain, 795 patients with obscure weight loss, and 62 patients with obscure intestinal obstruction. Examinations were performed through the mouth and/or anus according to the clinical symptoms and abdominal images. If a lesion was not detected through one direction, examination through the other direction was performed as necessary. Eighty-four patients with small-bowel polyps, 26 with intestinal obstruction caused by enterolith, and 18 with bleeding from Dieulafoy's lesions in the small intestine were treated endoscopically.ResultsA total of 2806 patients underwent double-balloon enteroscopy, and no serious complications occurred. An endoscopic approach through both the mouth and anus was used in 212 patients. Lesions were detected in 1696 patients, with a detection rate of 60.4%; the rates for obscure digestive tract bleeding, diarrhea, abdominal pain, weight loss, and intestinal obstruction were 85.9% (483/562), 73.5% (336/457), 48.2% (448/930), 49.1% (390/795), and 62.9% (39/62), respectively. For patients with small-bowel polyps who underwent endoscopic therapy, no complications such as digestive tract bleeding and perforation occurred. Intestinal obstruction with enteroliths was relieved with endoscopic lithotripsy. Among the 18 patients with bleeding from small-bowel Dieulafoy's lesions, 14 patients were controlled with endoscopic hemostasis.ConclusionDouble-balloon enteroscopy is useful for diagnosing and treating some small-bowel disease.
