[Appropiateness of colonoscopy in a gastrointestinal unit in 2001: a prospective study using criteria established by a European panel of experts].

UNLABELLED: Criteria for appropriateness of colonoscopy have been elaborated by an European Panel (EPAGE).

OBJECTIVES: 1) To assess the feasibility of EPAGE criteria in clinical practice, 2) to assess colonoscopy appropriateness using EPAGE criteria, 3) to compare colonoscopy appropriateness and findings.

PATIENTS AND METHODS: Four hundred and six consecutive examinations were included. The referral indication was judged using a scoring system on the basis of the EPAGE criteria.

RESULTS: Appropriateness could be assessed in 94% of the colonoscopies. Fifty-four percent were appropriate, 40% equivocal, and 6% inappropriate. Rate of abnormal colonoscopy was not different between the 3 groups, however endoscopic findings were more severe when the indication was appropriate. In the appropriate group, adenomatous polyps were more frequent (24%) than in the two other groups (13% and 12%; P<0.05) and tended to be larger in size. In the inappropriate group, patients were significantly younger, and no cancer was found. There were 5 colonic cancers in the inappropriate group and 12 in the appropriate group.

CONCLUSION: Colonoscopy is generally not overused according to EPAGE guidelines. However, on an individual basis it could be rather difficult to determine colonoscopy appropriateness using a scoring system. Indeed, a third of the indications was judged equivocal and the endoscopic findings were no different whether indication was appropriate or equivocal.
