Reviewer’ s report
Title: Production of ERCP training model using a 3D printing technique (with video)
Version: 1Date: 14 Dec 2019
Reviewer: Akira Imoto
Reviewer's report:
This new training model seems to be more convenient and cost-effective than the previous models.
It's shame that this model could not realize the way to the duodenum, but I think it's veryuseful.Minor; Is the feel of the sausage cutting up at the time of EST similar to the actual one ? Theactual EST needs to be done while taking care of perforation of the bile duct, so I think that theobject to cut should be a tube. Please consider this in a more detail.
