Video capsule endoscopy (VCE) is a useful examination for evaluation of small bowel lesions. One of the major complications is the capsule retention due to gastrointestinal stenosis. The patients with Crohn's disease, previous small bowel surgery or chronic NSAIDs users were considered at higher risk of capsule retention. The patency capsule (PC) has been available in Japan since July 2012. In the current study, we examined the usefulness of PC for the prediction of capsule retention in 20 high risk patients. PC test was performed in patients with previous abdominal operation (12/20; including 2 Crohn's disease), suspected bowel obstruction by CT examination (2/20), chronic NSAIDs use (5/20) or in an elderly person (1/20). Successful PC test was defined as the absence of the PC on abdominal X-ray exam at 33 hours post-ingestion. PC test was unsuccessful in 20% (4/20) of patients; 3 with previous abdominal operation (Crohn's disease, gastrectomy and cholecystectomy) and 1 with suspected bowel obstruction by enteritis. Three of 12 (25%) postoperative patients failed in PC test. VCE was not performed when the PC was retained. Eighty percent (16/20) of patients with successful PC test underwent safely VCE without capsule retention. In conclusion, the feasibility of VCE in high risk patients may be predictable safely and precisely by using the PC system. |
