Outcomes of EMR of defiant colorectal lesions directed to an endoscopy referral center
Gastrointestinal Endoscopy, 06/14/2012
Buchner AM et al. – Defiant polyp (DP) consist predominantly of sessile and flat adenomas including serrated adenomas. Most DPs can be successfully eradicated at dedicated therapeutic colonoscopy by using adjunctive resection and ablation techniques. The R0 rate is high and the adverse event rate is low. A relatively high rate of local residual/recurrent neoplasia at the resection site underscores the importance of follow–up colonoscopy.
