Training gastroenterology fellows to perform gastric polypectomy using a novel ex vivo model

Figure 1 Ex vivo porcine organ package including esophagus, stomach and duodenum in a handmade simulator shell.

Figure 2 Use of the simulator for evaluation. A: One approximate 8-mm gastric polyp artificially created with a rubber band ligation device in the porcine stomach cardia; B: Snare being advanced to encircle the polyp; C: Successful removal of the entire lesion; D: Application of a hemoclip.

Figure 3 Use of the simulator for training: several artificial polyps placed in different position in the porcine stomach. Use of a multiband ligation device reduced the time required to load rubber bands, allowing efficient creation of multiple artificial polyps.
