POSITIVE IMPACT OF SWITCHING FROM BSG TO ESGE POST POLYPECTOMY GUIDELINES ON A COLONOSCOPY SURVEILLANCE WAITING LIST

Aims:

Assess current compliance and the impact of switching surveillance recommendations.

Methods:

A consecutive sample of surveillance patients was identified. Indication, surveillance interval, index endoscopy and histology findings were documented. Compliance with BSG and impact of switching to ESGE guidelines was determined.

Results:

To date, 261 cases have been reviewed, 93 were excluded (86 (33%) non-polyp surveillance and 7 (3%) insufficient data). Of 168 post polypectomy cases, 60% were men and mean age 67 (35 – 89) years, compliance with BSG recommendations was 62% (n = 104). Of the 64 (38%) with inappropriate intervals, 31 (18%) did not require surveillance, 8 (5%) should have had a longer interval (median 18 months), and 25 (15%) a shorter interval (median 24 months).

Of the 137 requiring surveillance, in 108 (79%) the interval would be extended by a median of 60 months by switching from BSG to ESGE recommendations, only 14 (10%) would be shorter, median 24 months and 15 (11%) remain unchanged. In those requiring surveillance, if compliance with BSG guidelines was 100%, our surveillance intervals would actually have been reduced by 456 months. Conversely, switching to ESGE recommendations would extend intervals by 6,144 months and 3,809 months assuming 100% and 62% compliance.

Conclusions:

Our data confirms surveillance guideline compliance remains an issue. While optimising compliance is important, adopting ESGE intervals would have a greater impact on colonoscopy demand.
