['Although the "submucosal cushion" technique or injection-assisted polypectomy (IAP) is often used to resect colon polyps, little is known on the influence of this technique on histologic interpretation. We aimed to evaluate whether the use of a submucosal cushion improves the histologic and margin evaluation of colon polyps.', 'Consecutive patients undergoing polypectomy with and without IAP were included. An experienced blinded gastrointestinal pathologist evaluated the specimens using standardized criteria.', 'One hundred eleven sessile colon adenomas were analyzed (IAP, n = 65, standard, n = 46). Two-thirds of polyps ranged in size from 10 to 20 mm; the average polyp size was 13.2 mm for IAP and 9.9 mm for standard snare polypectomy (P = .001). The cautery degree, cautery amount, and margin evaluability, did not differ substantially with regard to the resection technique. For polyps ≥10-20 mm, the overall architecture quality was better in polyps resected with standard technique as compared with IAP.'] Does the submucosal cushion improve the histologic evaluation of adenomatous colon polyps resected by snare polypectomy?
