OBJECTIVE Cold snare polypectomy (CSP) is an accepted technique to remove diminutive or small (6-9 mm) polyps. Here we present a series of CSP for advanced non-pedunculated polyps (> 10 mm). METHODS This is a retrospective, single operator study. A total of 111 patients with non-pedunculated polyps (Paris classification 0-IIa, 0-IIb, 0-Is) estimated > 10 mm, underwent CSP. RESULTS A total of 129 polyps were removed (87 0-IIa, 18 0-IIb, 24 0-Is). The number of these polyps ranked according to size were as follows : 11-19 mm : 63 (49%), 20-29 mm : 44 (34%), > 30 mm : 22 (17%). Thirty-eight (29.5%) were sessile serrated adenomas, 47 (36%) were tubular adenomas, 25 (19.3%) were villous adenoma's and 18 (14%) were hyperplastic polyps. Forty-nine (38%) polyps were resected in a piecemeal fashion, submucosal injection with diluted Indigo Carmine was used in 24 (19%). Immediate oozing bleeding was frequent but in almost all patients rapid spontaneous haemostasis occurred. In only one patient haemostatic clipping was required (in order to achieve hemostasis). Preventive clipping was used in 3 patients. There were no complications. Seventy-two patients (with 87 lesions) had a follow-up colonoscopy. Of these 87 lesions, 9 had residual adenomatous tissue (10.3 %). According to the size of the original polyp, the distribution was as follows: 11-19 mm : 2/36 (5.5 %), 20-29 mm : 4/32 (12.5 %), > 30 mm : 3/19 (15.7%). CONCLUSIONS CSP for advanced, non-pedunculated lesions is feasible, effective and extremely safe.

D012189 Retrospective Studies Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
