About 15% of large (\u226520 mm) nonpedunculated colorectal polyps (LNPCPs) removed by piecemeal endoscopic mucosal resection (EMR) have evidence of recurrence at the first endoscopic follow-up. This rate has been around 5% since the advent of thermal treatment of the defect margin after EMR. Recurrence is often considered a major downside of piecemeal resection and one argument favoring en bloc resection.<\/p>\n\n\n\n
In a large experience spanning 139 months, 213 (14.6%) patients had residual adenoma at surveillance. Most recurrences were small polyps, with 48% ranging from 2.5 to 5.0 mm in size and 78.7% unifocal. Of 202 patients with macroscopically visible residual adenoma, 96% underwent successful endoscopic treatment.<\/p>\n\n\n\n
Treatment typically involved another attempt at submucosal injection followed by snare resection or just hot snare resection. For flat and fibrotic areas, cold-forceps avulsion with adjuvant snare-tip soft coagulation was used.<\/p>\n\n\n\n
Only one endoscopic treatment was necessary to cure recurrence in 85.2% of patients. Nine patients (4.2%) eventually required surgery for failure to eradicate residual adenoma.<\/p>\n","protected":false},"excerpt":{"rendered":"
