Preliminary assessment of two novel mechanical colonoscopic polypectomy simulators: Description evaluation and validation

摘要

Background and study aims Colonoscopic polypectomy is an essential endoscopic skill. The simulators available for training are limited and based on raw porcine colons. Animal intestines are inconvenient and offer limited advantages for polypectomy training. These limitations are avoided by two novel mechanical simulators — the magnetic system based simulator (MSPS) and the simulator for polypectomy with high frequency current (HFPS) — described here. They are equipped to demonstrate self-repair of polyps after making a cut and hybrid polyps. The aim of this study was to describe and establish face, content, and construct validity of the two simulators and to assess their perceived utility as training and assessment tools.
