Development and Evaluation of an Interventional Training Model for Flexible Endoscopy In Roux-En-Y Anatomy

Aims Surgery in the upper gastrointestinal tract can result in significantly altered anatomy. A common variation of the resulting anatomy is the Roux-Y reconstruction. Altered anatomy leads to an increasing risk for technically failures during follow-up endoscopies. Especially interventions for choledocholithiasis after bariatric surgery are complex. A realistic and patient-analogue training model is not yet available, but could improve the quality of diagnostic and therapeutic endoscopy in patients with surgically altered anatomy.

Methods The altered anatomy was reconstructed entirely with digital 3D programs using patient-analog data. Materials from textile research as well as rigid and flexible 3D printing materials were used for tissue reconstruction. Furthermore, artificial tissues were used to reconstruct realistic and interventional organ structures of the upper gastrointestinal tract without the use of animal material. Technical evaluation of the model combined with a short questionnaire was done during an ERCP workshop with 10 participants.

Results A modular hands-on training phantom which shows a Roux-en-Y Reconstruction after partial gastric resection was planed and developed. Evaluation was done by interventional endoscopic specialists. On a scale of 1 (very realistic) to 5 (not realistic at all), the average score for the overall impression of the model was 1.9. In addition, the individual sections and areas of the model were assessed according to various criteria.

Conclusions We developed and tested a patient-analog model to train endoscopic interventions in patients with postoperatively altered anatomy successfully.
