title: Korean experience with double balloon endoscopy: Korean Association for the Study of Intestinal Diseases multi-center study.
abstract: BACKGROUND
  Double balloon endoscopy (DBE) is a new diagnostic and therapeutic tool for the management of patients with small-bowel disease.
  
  
  OBJECTIVE
  To evaluate the feasibility, clinical usefulness, and safety of DBE in Korean patients with suspected or known small-bowel disease.
  
  
  METHODS
  Retrospective, multicenter study from April 2004 to March 2006.
  
  
  METHODS
  University hospitals.
  
  
  METHODS
  Two hundred twenty-five consecutive patients.
  
  
  METHODS
  Subjects underwent 311 procedures with DBE via the oral and/or anal routes.
  
  
  METHODS
  The indications, diagnostic yield, therapeutic use, and complications.
  
  
  RESULTS
  Overall diagnostic yield was 75% (169/225). Diagnostic yields for obscure GI bleeding (OGIB) (n = 137), chronic abdominal pain (n = 32), radiologic/capule endoscopic abnormality (n = 25), polyposis (n = 9), and chronic diarrhea (n = 9) were 73.7% (101/137), 75.0% (24/32), 64% (16/25), 100% (9/9), and 0% (0/9), respectively. In patients with OGIB, ulcerating lesions (n = 54) were more common than vascular lesions (n = 20) or tumors (n = 27). Some lesions detected in DBE were treated effectively with electrocoagulation or argon plasma coagulation, polypectomy, and dilation. Entrapped capsules were removed easily with polypectomy snare in 3 patients with small-bowel stricture. Some patients with strictures had transient abdominal discomfort during and/or after the procedure. With the exception of 1 mucosal tear, there were no technical problems or serious complications.
  
  
  CONCLUSIONS
  Descriptive, retrospective study.
  
  
  CONCLUSIONS
  DBE is safe and useful for diagnosis and treatment of a variety of small-bowel diseases. The most common indication of DBE was OGIB. Ulcerating small-bowel lesions are more common than vascular lesions in Korea.
