Cold snare polypectomy: A closer look at the efficacy and limitations for polyps 10-20 mm in size.

Current guidelines recommend cold snare polypectomy for polyps less than 10 mm in size. Conversely, endoscopic mucosal resection is still the preferred technique for larger polyps. Concerns regarding cold snare polypectomy for larger polyps revolve around the difficulty in conducting resection (resulting in piecemeal removal), and the potential for local residual polyp tissue and a high rate of recurrence.

Sublingual hyoscyamine spray as premedication for colonoscopy: a randomized double-blinded placebo-controlled trial.

Background: Colonic motility and spasm during colonoscopy may affect duration and quality of the examination as well as patient comfort during and after the procedure. Previous studies assessing the utility of antispasmodic agents in colonoscopy demonstrated conflicting results. The aim of this study was to determine the effect of sublingual hyoscyamine spray (IB-Stat, Inkine Pharmaceutical) on the performance of colonoscopy.
