Background/Aims: Recent data suggest that the incidence of ulcerative colitis (UC) related colorectal cancer (CRC) in Indiais similar to that of West. The optimum method for surveillance is still a debate. Surveillance with random biopsies has been thestandard of care, but is a tedious process. We therefore undertook this study to assess the yield of random biopsy in dysplasiasurveillance. Methods: Between March 2014 and July 2015, patients of UC attending the Inflammatory Bowel Disease clinicat the All India Institute of Medical Sciences with high risk factors for CRC like duration of disease >15 years and pancolitis,family history of CRC, primary sclerosing cholangitis underwent surveillance colonoscopy for dysplasia. Four quadrant randombiopsies at 10 cm intervals were taken (33 biopsies). Two pathologists examined specimens for dysplasia, and the yieldof dysplasia was calculated. Results: Twenty-eight patients were included. Twenty-six of these had pancolitis with a durationof disease greater than 15 years, and two patients had associated primary sclerosing cholangis. No patient had a family historyof CRC. The mean age at onset of disease was 28.89±8.73 years and the duration of disease was 19.00±8.78 years. Eighteenpatients (64.28%) were males. A total of 924 biopsies were taken. None of the biopsies revealed any evidence of dysplasia, and7/924 (0.7%) were indefinite for dysplasia. Conclusions: Random biopsy for surveillance in longstanding extensive colitis hasa low yield for dysplasia and does not suffice for screening. Newer techniques such as chromoendoscopy-guided biopsies needgreater adoption.
