Endoscopic mucosal resection (EMR) is the cornerstone of the treatment of large (\u226520 mm) nonpedunculated colorectal lesions. This study from a Canadian expert center examined risk factors for recurrence over a 2-year interval ending in March 2019.<\/p>\n\n\n\n
Among 265 patients, 14% had undergone a prior attempt at resection. The overall recurrence rate at first follow-up was 14.7%. This recurrence rate was despite use of snare tip soft coagulation (STSC) thermal treatment of the margin in 94% of patients. Adjunctive techniques to complete resection were used in 31% of patients, including hot avulsion in 95% of cases and cold avulsion in only 5%. <\/p>\n\n\n\n
In a multivariable analysis, recurrence was not associated with age, lesion size or location, prior resection attempt, intraprocedural bleeding, or high-grade dysplasia (all of these have been associated with recurrence in one or more prior studies). Recurrence was associated with male gender (odds ratio [OR], 3.31) and use of hot avulsion (OR, 2.87).<\/p>\n","protected":false},"excerpt":{"rendered":"
