In clinical practice, colonoscopists sometimes think that patients with large nonpedunculated colorectal lesions should be referred to surgery after one or two attempts at resection and polyps persist. <\/p>\n\n\n\n
In a study from an Australian consortium, 12% of 1292 large (\u226520 mm) nonpedunculated colon polyps underwent a prior attempt at resection (PAs). In the PA lesions, technical success of resection was 93%, which increased to 95.6% if the procedure was performed in two stages.<\/p>\n\n\n\n
For all lesions, nonfibrotic portions were removed by conventional EMR, followed by the CAST technique (cold forceps avulsion with adjuvant snare-tip soft coagulation [STSC] in the avulsed region). The total time to remove PA lesions was longer (35 vs 25 minutes), and the CAST technique was used more often (46.2% vs 7.6%). Among 127 PA lesions undergoing follow-up, overall recurrence was 7.8%, and no patients were referred for surgery at first follow-up. Of 65 lesions in which the margin was treated by STSC, there was no recurrence versus an 18% recurrence rate at first follow-up if STSC had not been used. Clip closure was used routinely in areas of CAST treatment to prevent delayed perforation, and no delayed perforations occurred.<\/p>\n","protected":false},"excerpt":{"rendered":"
