Impact of submucosal saline solution injection for cold snare polypectomy of small colorectal polyps: a randomized controlled study

摘要

Background and Aims: Cold snare polypectomy (CSP) of small colorectal polyps is widely used. However, the technique is still troubled by insufficient resection depth, which may prevent precise pathologic evaluation. In this study, we investigated whether submucosal injection of saline solution helps to achieve deeper resection in CSP.
