Development of a novel and simple ex vivo biologic ERCP training model.

Background: Training and teaching of ERCP in biologic models has gained importance over the past decade. However, many existing models are expensive, are not widely available, or rely on live animals.

Objective: We describe a novel and simple ex vivo, biologic model for hands-on teaching.

Hemostatic effect of oxidized regenerated cellulose in an experimental gastric mucosal resection model.

Background And Study Aim: The endoscopic hemostatic therapies currently available do not always result in hemostasis of gastrointestinal bleeding. Oxidized regenerated cellulose (ORC) mesh is a widely available surgical hemostatic material. The aim of this study was to evaluate the hemostatic efficacy of ORC in experimental gastric hemorrhage after endoscopic resection.
