title: Diagnostic effect of capsule endoscopy in 31 cases of subacute small bowel obstruction.
abstract: OBJECTIVE
  To evaluate the effectiveness and safety of capsule endoscopy (CE) in patients with recurrent subacute small bowel obstruction.
  
  
  METHODS
  The study was a retrospective analysis of 31 patients referred to hospital from January 2003 to August 2008 for the investigation of subacute small bowel obstruction, who underwent CE. The patients were aged 9-81 years, and all of them had undergone gastroscopy and colonoscopy previously. Some of them received abdominal computed tomography or small bowel follow-through.
  
  
  RESULTS
  CE made a definitive diagnosis in 12 (38.7%) of 31 cases: four Crohn's disease (CD), two carcinomas, one intestinal tuberculosis, one ischemic enteritis, one abdominal cocoon, one duplication of the intestine, one diverticulum and one ileal polypoid tumor. Capsule retention occurred in three (9.7%) of 31 patients, and was caused by CD (2) or tumor (1). Two with retained capsules were retrieved at surgery, and the other one of the capsules was spontaneously passed the stricture by medical treatment in 6 mo. No case had an acute small bowel obstruction caused by performance of CE.
  
  
  CONCLUSIONS
  CE provided safe and effective visualization to identify the etiology of a subacute small bowel obstruction, especially in patients with suspected intestinal tumors or CD, which are not identified by routine examinations.
