摘要
Aims To determine the completeness of polyp resection (i.e. achieving an R0 margin) and its relation with Endoscopists, histopathologist, size, location and technique of polypectomy in an NSS cohort. The definition of R0 margin is complete macroscopic resection with a negative microscopic margin at polypectomy. Method NCCS (National Colon Cancer Screening) colonoscopies are offered to bowel cancer screening patients after a positive faecal immunochemical test (FIT) test in a Joint Advisory Group (JAG) accredited Gastrointestinal Endoscopy centre. We histologically evaluated the polyp margins for complete resection, which was defined as the absence of adenomatous or hyperplastic tissue in the resected polyp margins in a cohort of faecal immunochemical test positive patients. Results A total of 186 consecutive NCCS colonoscopies out of a total of 542 performed between 2013 and 2017 were included in this study. Of the polyps excised 152(27%) had a R0 margin histologically, and 30(5%) had involvement of the margin. Surprisingly in 373(67%) of polyps pathologists were unable to assess the margin. Conclusion Achieving an R0 margin should be a key performance indicator for endoscopists performing polypectomy. At the same time more studies on polyp margins are recommended.
