Aim: The National Institution for health and care excellence (of United Kingdom) updated their guidelines for colorectal cancer follow up in 2011. This included the recommendation for a 1 year post op surveillance colonoscopy to detect metachronous malignant and premalignant colorectal tumours. The aim of this study was to assess the efficacy of this aggressive surveillance policy. Method: Seventy-five consecutive patients who had undergone colorectal resections with curative attempt over a 12 month period after the publication of the 2011 guidelines. Outcome after their 1 year surveillance colonoscopy was examined to determine the incidence of new colorectal cancers and adenomatous polyps. Results: Of 75 (male = 47) patients (median (range) 71 (34-89)) were included. No new colorectal cancers were detected at 1 year surveillance colonoscopy. New adenomatous polyps were detected in 11 of the 75 patients (15%). Conclusion: The 2011 NICE guidelines include both a recommendation for full pre operative colonoscopy to detect synchronous tumours, and one and 5 yearly post operative colonoscopies to detect metachronous lesions. The evidence for the efficacy for early surveillance is unclear. We detected no new colorectal cancers and only 15% had new adenomatous polyps at one year indicating that early surveillance may not be warranted.
