ABSTRACT

Background: The biological inanimate simulators allow the development of skills in endoscopy. The extramucosal pyloromyotomy is the standard treatment for hypertrophic pyloric stenosis (HPS). The peroral endoscopic route transect the hypertrophic circular muscle layer. This procedure has excellent results; however, for non-expert endoscopists, identifying circular muscle layer is difficult and increases the risk of perforation. Objective: To evaluate the feasibility of using inanimate biological simulators for endoscopic training in endoscopic pyloromyotomy (EPM). Methods: Experimental design without control group in inanimate pig biological model. Two endoscopists surgeons with prior experience in endoscopic submucosal dissection and cardiomyotomy. We assess the different phases (technical success, complications, time). Descriptive statistics were performed. Results: We performed 18 EPM, in mean time 28.1 ± 11.7 minutes. The assessment of the piece was positively correlated with the endoscopic image. The site for EPM approach is related to the time of procedure; being greater on greater curvature of the antrum. There was variability in the procedure time, being lower in the anterosuperior antrum wall. No complications such as perforation occurred and 6 EPM were reported incomplete as confirmed by pathology. Conclusions: The porcine inanimate biological model allows training in complex endoscopic techniques with wide safety margin. The location of the submucosal tunnel was directly related to the feasibility of the EPM. This model is ideal for evaluating complications such as perforation and incomplete EPM.
