Model for wall loads during endoscopy

University Hospital of Tuebingen, Tuebingen, Germany
Endoscopic assessment is crucial to the treatment of biliopancreatic diseases. As of yet, the wall load during this type of endoscopy is unknown, as it is not directly measurable in patients. Therefore, in this study an endoscopy training model comprising an esophagus, a stomach, and a duodenum, was redesigned and five areas with increased wall stress during endoscopy in the model were identified using different duodenoscopes. These areas were equipped with a sensor system consisting of five load cells. Fifteen standardized duodenoscopies were performed. The wall stress during duodenoscopies was measured intraprocedurally for the first time in this work using a synthetic, human–analogue model.
