Characterization and significance of protrusions in the mucosal defect after cold snare polypectomy (original) (raw)

Gastrointestinal endoscopy, 2015

Abstract

Cold snare polypectomy (CSP) is widely practiced; however, the endoscopic features of the CSP mucosal defect have not been studied. In particular, protrusions within the cold snare defect (CSDPs) may create concern for residual polyp. The frequency and constituents of this phenomenon are unknown. To describe the frequency, predictors, and histologic constituents of CSDPs. Prospective observational study. Tertiary-care hospital endoscopy unit. Eighty-eight consecutive patients undergoing CSP for a polyp ≤ 10 mm in size. Inspection of the cold snare mucosal defect with high-definition white light and biopsy sampling of CSDPs for separate histologic assessment, when present. Frequency and constituents of CSDPs. Two hundred fifty-seven consecutive polyps ≤ 10 mm in size were removed in 88 patients (50 men [57%], mean age 63 years). Polyps were predominately adenomatous (162, 63%), located in the proximal colon (159, 62%) and flat (200, 78%). Mean lesion size was 5.5 mm (range, 2-10 mm)....
