Colon Polyps Endoscopic Detection Versus Microscopic Confirmation

Aims Colon polyps mucosal protrusions occurring in the colon lumen most commonly sporadic or as part of other syndromes. Bowel polyps are very common, affecting around 1 in 4 people aged 50 or over. Serrated polyps have been recognized in the last decade as important premalignant lesions accounting for between 15 % and 30 % of colorectal cancers.

We did an Audit about hyperplastic Polyps in bowel cancer screen patients, its site, and terminology used to describe the polyps on endoscopy report as per BSG Guidelines for example Hyperplastic polyps (HP), Sessile serrated lesion (SSL),and SSL with Dysplasia, confirming is against histopathology report. We tried to find how accurately the polyps can be detected on endoscopy and the terminology used as per guidelines.

Methods Its retrospective audit,all patients who had bowel cancer screening colonoscopy from Jan 2018 till Dec 2018.Data was collected from the endoscopy reports and then compared with the histology reports,hospital electronic reporting system was used.

Results

Total number of colonoscopies = 827

Total number of patients with polyps = 505 (61.06 %)

Total number of patient (Jan 2018 till Dec 2018) 827

Total number of patients identified to have polyps 505 (all lesions)

Percentage of patients with polyps (all lesions) 61.06 HP/SSL identified during endoscopy 22 Histology Report confirms HP/SSL in 131 Percentage endoscopist correctly identifies HP/SSL 16.7 Percentage of patients having HP/SSL 25.9

Conclusions Hyperplastic polyps are more common on the left side of the colon(rectum and sigmoid).There are still more than 30 % HP/SSL on the right side of the colon with clinical significance. We need to update the endoscopy reporting system to facilitate endoscopists to correctly identify these lesions,the terminology needs to be used as per the British Society of Gastroenterology guidelines.There is further work needed to do the data and clinical significance of HP/SSL lesions.
