Background and Aim: The risk of developing colorectal cancer is higher in patients with ulcerative colitis (UC) than in the general population. Guidelines recommend surveillance colonoscopy (SCS) to reduce mortality; however, few studies have assessed physicians’ adherence to guidelines. This study was aimed to clarify the current status of SCS and adherence to guidelines through the characteristics of cancer/dysplasia surveillance for UC patients in Japan. Methods: A questionnaire was mailed to 541 physicians who attended meetings on inflammatory bowel disease. Results: The respondents encountered a median of 100 UC cases. Thirty percent of the respondents had never managed a UC patient with cancer. Fifty-one percent of the respondents had never diagnosed colorectal cancer with UC. Forty-seven percent of the respondents considered extensive colitis and left-sided colitis as indications for SCS, and 38% carried out SCS regardless of the disease extent. Sixty-three percent of the respondents started SCS at 7–10 years after UC onset, whereas 20% started SCS at 3 years or less. Fifty-two percent of the respondents obtained targeted biopsies only, and chromoendoscopy was used by 49% of the respondents as a special technique for surveillance. Median number of biopsies at SCS was five per patient; it was three among patients whose biopsy was carried out by physicians who obtained targeted biopsies only and seven among those carried out by physicians who obtained step biopsies and targeted biopsies (P < 0.0001). Conclusion: A considerable proportion of the respondents did not follow the guidelines when selecting patients for surveillance and carrying out SCS.
