895 Innovating Automated Progress Tracking System (APS) for Laparoscopic Simulation Training in Low-Middle-Income-Countries Using LaApSi Models: Low-Cost High-Fidelity Performance Assessment System with Microcontroller Connectivity

Abstract

Abstract Aim To develop a Low-Cost Automated Progress tracking system (APS) embedded in the silicon based Laparoscopic Appendicectomy Simulation (LaApSi) Model which enables real-time assessment of Laparoscopic Appendicectomy (LA). To assess its application and validity in the low-resource setting via Laparoscopic Surgery courses. Method APS architecture includes thin insulated wires embedded in the LaApSi Models at the mesoappendix, appendicular artery, and the base of the appendix which acts as an indicator when cut during the appendicectomy. These wires are further connected to the Printed Circuit Board (PCB) located at the base of the model which connects with the microcontroller and establishes communication with the computer giving real-time data. Results The prototyped APS model was able to establish key features: 1. Total duration of the procedure 2. Identify potential surgical hazard: blood vessel injury 3. Length at which the appendicectomy is performed 4. Injury to surrounding structures. These performance data were recorded in the database for further review, analysis, and comparison for progression in the simulation training. The system is set up on a points basis hence when a user makes a surgical error e.g., blood vessel injury during the surgical simulation in the APS LaApSi Model, -20 points (Blood Vessels Cut) appear on the computer screen (images available). Further assessment and validity of the APS models are planned to be carried out in low-resource settings in the next 8 weeks. Conclusions The availability of a model blueprint of this cost-effective APS system (<20£) to LMICs will address the key barrier of surgical simulation in low-resource settings.
