Cold snare is now considered the polypectomy method of choice for polyps <10 mm in size, and recent studies have extended the use of cold polypectomy to some lesions \u226510 mm in size.<\/p>\n\n\n\n
In the current study, 142 lesions 4 to 9 mm in size and 40 lesions 10 to 20 mm in size were removed by cold snare polypectomy. After resection, 2 biopsy samples were taken from the resection margin of the 4- to 9-mm lesions, and 4 quadrant biopsy specimens were obtained from the resection margin defect for 10- to 20-mm lesions. <\/p>\n\n\n\n
Conversion to hot snare resection was required in less than 1% of 4- to 9-mm lesions but was necessary in 44% of the 10- to 20-mm lesions. Visible residual polyp was seen after “initial” resection in 13% of 4- to 9-mm lesions and 18% of 10- to 20-mm lesions. Of the lesions removed by a cold snare without conversion to a hot snare, 19% had incomplete resection, as judged by margin biopsy, without much difference between size categories. <\/p>\n\n\n\n
The overall rate of incomplete resection was 26% for serrated lesions, but the difference was not significant. Incomplete resection was associated with flat lesions (odds ratio [OR], 2.9), resection judged as difficult (OR, 4.2), piecemeal resection (OR, 6.6), and visible polyp after “initial\u201d resection (OR, 5.4). Among endoscopists with \u226510 resections, the rate of incomplete resection ranged from 8% to 33%. Overall, 63% of 10- to 20-mm polyps had either incomplete resection or required conversion to hot snaring. Neither use of dedicated snares nor submucosal injection affected complete resection rates.<\/p>\n","protected":false},"excerpt":{"rendered":"
