<abstract abstract-type="main" id="codi12122-abs-0001"> <title>Abstract</title> <sec id="codi12122-sec-0001" sec-type="section"> <title>Aim</title> <p>Endoscopic resection is the primary treatment for colorectal adenoma, but in some cases surgery is necessary. The aim of this retrospective study was to define the prevalence and predictive factors for surgery in patients with advanced colorectal adenoma managed in a referral endoscopy centre.</p> </sec> <sec id="codi12122-sec-0002" sec-type="section"> <title>Method</title> <p>Consecutive patients diagnosed with advanced adenoma (Class 4 in the Vienna classification) during a colonoscopy from 2007 to 2009 in the endoscopy centre of the University Hospital of Rennes were included. Predictive factors of surgery were determined by univariate and multivariate analysis.</p> </sec> <sec id="codi12122-sec-0003" sec-type="section"> <title>Results</title> <p>Two‐hundred and twelve (135 male) patients with a mean age of 65.8 years were included. The reason for colonoscopy was for diagnosis in 63.2%, surveillance in 25.5% and screening in 11.3%. These referred patients amounted to 20.8% of all patients having colonoscopy. Surgery was performed in 13.7% of the 212 patients and in 16 (8.3%) of the 192 patients in whom endoscopic removal was attempted. In the subgroup of 192 patients, univariate analysis revealed that body mass index (<italic>P</italic> = 0.04), histology (<italic>P</italic> = 0.002), size (<italic>P</italic> = 0.03) and macroscopic appearance (<italic>P</italic> < 0.001) of the polyp were associated with surgery. Multivariate analysis revealed that the macroscopic appearance and histology only were significantly associated with surgery.</p> </sec> <sec id="codi12122-sec-0004" sec-type="section"> <title>Conclusion</title> <p>Surgery was needed in 13.7% of patients with an advanced adenoma, but in only 8.3% of the subgroup of 192 patients in whom endoscopic removal was attempted.
