Abstract:
Objective This study aim to established an in-vivo porcine model for the training of super minimally invasive endoscopic dissection (ESTD).
Methods The trainees were trained for 3 months, and a total of 8 live pigs were operated. Super minimally invasive endoscopic submucosal dissection (ESD) and ESTD animal training models were established. The trainees studied the surgical theory, performed ESTD and ESD under the guidance of senior doctors. We recorded the overall operation time, tunnel length, wound area size, and operation speed (wound area/ time). A questionnaire was used to detect changes in competence before and after training. Data were analyzed using the SPSS.23 statistical software.
Results The ESD and ESTD surgical anatomy models showed no ununtreated intraoperative major bleeding and delayed postoperative bleeding during surgical training. Two cases of small esophageal perforation appeared in ESTD models, all were closed with soft tissue clips. None of the surgical models had delayed perforation. There ESD cases and one ESTD case were unfinished and senior doctors needed to take over, and no animal died.
Conclusion The in-vivo porcine model is effective and feasible for endoscopic tunneling and submucosal dissection surgery training, which is beneficial to improve the endoscopic learning curve of trainees.
