Abstract:
Introduction Colonoscopy trainers have gained recognition for improving endoscopy skills and preparing for real procedures on humans. Unfortunately, due to their high price, commercial simulators are hard to obtain, especially for small medical centers. However, a solution might be to construct a device for themselves. Aim Our goal was to build a relatively cheap and easy-to-construct simulator for residents who want to start learning colonoscopy. Materials and methods The box model colonoscopy trainer was designed and constructed. The artificial colon was made from 2 layers of fabric and rubber rings between them. Velcro attached to the artificial colon and to the box, and the tarp straps that simulate peritoneal adhesions allow the bowel to be arranged in many different configurations. Moreover, some aspects of polypectomy training have been incorporated in the colonoscopy simulator. Results The self-constructed simulator was found to be an effective training device, with the total cost of parts not exceeding $30. Conclusions In this paper, we present the first homemade simulator for colonoscopy training. It offers the opportunity for skills acquisition in a preclinical setting.
