Initial training in cold snare polypectomy for residents using a new training model

We have previously reported that the use of the Endoscopist & Assistant's Simulator drY lab (EASY; Tanac Co. Ltd., Gifu, Japan) ([Fig. 1]) was useful in recruiting residents [1]. The version of EASY described in this report (EASY CSP) is an endoscopic simulator for resection by snare and clip closure developed by Matsuzaki and Tsunemi ([Fig. 2]). The procedure can be practiced on the device, which has been developed for training in polypectomy and suturing techniques. It allows for easy training with simple set up.

EASY was used for cold snare polypectomy (CSP) by two of our residents who had no colonoscopy experience ([Video 1]). On the 25 polyp models, the first one in each row was used for instruction, and the remaining four polyps in the row were then used for practice. This was repeated for five rows. The time required to perform CSP on each of the 25 polyp models was measured. We found that the resection time gradually decreased and, through the use of EASY, a reduction in procedure time was obtained.

Adequate instruction for the 25 CSPs resulted in an increase in procedural proficiency. The use of the EASY CSP sheet before performing actual CSP on a patient is likely to be useful from a medical safety perspective. It is easy to introduce, inexpensive, and may become a standard part of training endoscopists in the future. In addition to the standard endoscopy model, adding guidance by EASY appears to be useful as a part of endoscopist education.
