Abstract

ALBUQUERQUE, Walton et al. Complementation by argon plasma coagulation after endoscopic piecemeal resection of large colorectal adenomas. Rev. Col. Bras. Cir. [online]. 2013, vol.40, n.5, pp.404-408. ISSN 0100-6991.  http://dx.doi.org/10.1590/S0100-69912013000500010.

OBJECTIVE: To evaluate the efficacy of complement by argon plasma coagulation to reduce the rate of residual or recurrent tumor after complete endoscopic piecemeal resection of large sessile colorectal adenomas. METHODS: Inclusion criteria: patients with large sessile colorectal adenomas (e" 20 mm), without morphological signs of deep infiltration, submitted to complete endoscopic piecemeal resection studied with chromoendoscopy and magnification of images. Patients were randomized into two groups: group 1 - no additional procedure, and group 2 - complementation by argon plasma coagulation. follow-up colonoscopy was performed at three, six and 12 months postoperatively. We evaluated the rate of local recurrence or residual malignancy. RESULTS: The study included 21 patients, eleven in group 1 and ten in group 2. There were two local recurrences or residual tumors in each group, detected at three months follow-up. CONCLUSION: Complementation by argon plasma coagulation after apparent complete endoscopic piecemeal resection of large sessile colorectal adenomas does not seem to reduce the occurrence of residual adenomatous lesions or local recurrence.
