ABSTRACT
BACKGROUND AND STUDY AIMS:
Despite widespread use of cold snare polypectomy (CSP), the R0 resection rate is not well documented. We perform extended CSP, resecting polyps with a >â1âmm circumferential margin. The aim of this study is to compare the R0 resection rate of extended CSP with conventional CSP and to assess safety. PATIENTS ANDMETHODS:
From April 2014 to September 2016, 712 non-pedunculated colorectal polyps,â<â10âmm in size, resected using CSP from 316 patients were retrospectively analyzed.RESULTS:
We divided lesions into conventional CSP (nâ=â263) and extended CSP groups (nâ=â449). The baseline characteristics of these two groups were not significantly different in univariate or multivariate analyses. Sessile polyps comprised 94â% (668/712), and the remaining were flat-elevated polyps. Mean size of polyps (±standard deviation) was 4.2â±â1.5âmm. The most frequent pathology was low grade adenoma (97â%, 689/712). The R0 resection rate was significantly higher in the extended CSP group (439/449 [98â%]) than in the conventional CSP group (222/263 [84â%], P â<â0.001). There was no delayed bleeding or perforation in either group (conventional CSP group, 0/263, 95â% confidence interval 0.0â-â1.4â% and extended CSP group, 0/449, 95â% confidence interval 0.0â-â0.8â%).CONCLUSIONS:
Extended CSP results in a higher R0 resection rate compared with conventional CSP. Extended CSP did not result in a higher rate of delayed bleeding or perforation. Extended CSP is a safe and promising procedure for endoscopic resection of non-pedunculated colorectal polyps < 10âmm in size.
