FP4.9 - Adherence to post Colonic polypectomy surveillance guidelines

Abstract Aims The British Society of Gastroenterology updated its guidelines in 2020 regarding polyps follow-up following colonoscopy. The surveillance depends on type, size, number, and histology criteria. Our aim was to assess adherence of our hospital's endoscopy department to these new guidelines. Methods A retrospective analysis of all consecutive adult patients who underwent colonoscopy were included between January and March 2022 at our hospital. Data were collected and analyzed on excel. The endoscopy report was identified from MediLogik-EMS.Histology from PICS system. Demographics including the specialty of endoscopist was also included. Non-parametric data were expressed in their Median and IQR. Results Out of the 108 patients examined 50/108 (49%) were found to have polyps and were included in the analysis. F: M =1:2, median age 64 with IQR 18.5(59-77.5). Tubular adenoma was found in 58%, hyperplastic polyps in 12%, sessile serrated polyps in 10%, tubulovillous adenoma in 8%, adenocarcinoma in 8%, and inflammatory polyps in 4%. Histopathology revealed tubular adenoma with LGD in 58%, inflammatory polyps in 16%, adenocarcinoma in 8%. Polyps were removed using cold biopsy in 58% and hot snare in 38%. BSG guidelines were followed in 92% (46/50). The reason for not adherence was either histologically incomplete excision, requiring a site check within 2-6 months which was not performed in6%(3)or high-risk features requiring 3 yearly surveillance colonoscopy follow-ups not requested in 2%(1). Conclusion There is high adherence to the guidelines but still not 100%. Our aim is to achieve 100% adherence in the re-audit.
