Abstract:
Background: Cold snare defect protrusions (CSDPs) that occur after cold snare polypectomy (CSP) are considered indicators of incomplete polyp resection (IPR). We have sometimes experienced difficult polyp resection with snaring alone; in such cases, a forcible pull on the snare by the endoscopist is necessary. We call this procedure “forced CSP (FCSP).” However, no previous studies have addressed this point.
Methods: This is a prospective observational study (UMIN000 041718). From November 2020 to June 2021, the frequency, safety, and validity of FCSP were evaluated at our hospital. We distinguished CSP with snaring alone performed by the assistant and CSP requiring a forcible pull on the snare by the endoscopist as conventional CSP (CCSP) and FCSP, respectively.
Results: A total of 1315 polyps were removed. FCSP was performed on 105 polyps (8%, 105/1315). The perforation rate was 0% in both groups. The rate of CSDP after the procedure was 96.2% (101/105) and 6.4% (77/1210) in the FCSP and CCSP groups (p 〈 0.001), respectively. The rate of IPR was 12.5% (13/104) and 6.2% (75/1208) in the FCSP and CCSP groups (p=0.0224), respectively. Multivariable analysis identified polyps located in the cecum (risk ratio (RR), 1.13; 95% confidence interval (CI)=1.050-1.179); p=0.003) and polyps ≥6 mm in diameter (RR, 2.37; 95%CI=2.146-2.542); p 〈 0.001) as independent risk factors for FCSP.
Conclusions: FCSP was performed on 105 polyps (8%) in this study. There is the possibility that FCSP is associated with the occurrence of CSDPs and IPR. Further studies are necessary in the future to confirm our results.
