Abstract

Background and study aims Low adherence to the Dutch guideline for colonoscopy surveillance after polypectomy led to release of a new guideline in 2013. This new guideline was risk-stratified at a more detailed level than the previous one to achieve more efficient use of colonoscopy resources. This study assessed the feasibility of the risk-stratified guideline by evaluating correct interpretation of and adherence to this guideline.

Methods Based on semi-structured interviews with 10 gastroenterologists, we developed an online survey to evaluate gastroenterologists’ recommendations for surveillance in 15 example cases of patients with polyps. If recommended intervals differed from the new guideline, respondents were asked to indicate their motives for doing so.

Results Ninety-one of 592 (15.4 %) invited gastroenterologists responded to at least one case, of whom 84 (14.2 %) completed the survey. Gastroenterologists gave a correct recommendation in a median of 10 of 15 cases and adherence per case ranged from 14 % to 95 % (median case 76 %). The two cases that addressed management of serrated polyps were least often answered correctly (14 % and 28 % correct answers). Discrepancies were mainly due to misinterpretation of the guideline with respect to serrated polyps (48 %) or misreading of the questions (30 %).

Conclusions Median adherence to the updated colonoscopy surveillance guideline of 76 % seems reasonable, and is higher than adherence to the previous guideline (range: 22 %-80 %, median 59 %). This shows that detailed (more complex) risk stratification for designation of a surveillance interval is feasible. Adherence could potentially be improved by clarifying correct interpretation of serrated polyps.
