Introduction

Colonic polyp is a growth that develops on the lining of the colon. There are various type of polyps, adenomatous, serrated and hyperplastic. Specially adenomatous and serrated polyps have a potential to develop cancer over time.

Aims/Background

To check prevalence of rectal polyps detected on rectal Retro-flexion during colonoscopy.

Method

A total of 381 Colonoscopy reports were reviewed using Unisoft GI reporting tool at University Hospital Kerry, from Jan, 2022 to Feb, 2022. Each report has been individually checked whether there is photographic evidence of rectal polyp on rectal retro-flexion.

Results

381 Colonoscopies were performed during this time, 238(62.46%) reports have photographic evidence of rectal retro-flexion (N=381) while 143(37.53%) have no images of rectal retro-flexion. Out of 238(N=381) imaged, 12(3.14%) images have shown rectal polyps.

Conclusions

Rectal retro-flexion is an important maneuver during colonoscopy. Some polyps which are located very distally in the rectum closer to dentate line may be easily missed if rectal retro flexion is not performed. Our study has shown only small number of polyps (3.14%) were detected on rectal retro flexion which high lights importance of retro- flexion. There is probably a need for larger study to check whether a flat rectal cancer is detected on retro-flexion.
