Diseño y evaluación de un tejido sintético para la simulación de nudos y suturas mediante laparoscopia

Abstract

Abstract Introduction: The training of a surgical resident should include practical exposure to knowledge that has been translated into motor skills. The skills of suturing and knotting by laparoscopy are usually the first exposure in simulation centers, where the possibility of repeated practice improves the final performance in the residents. Finding in the market a product that simulates real tissue, like the intestine, easily and affordably, is difficult in our environment. We developed a synthetic tissue that was manufactured at home, which is economic, reusable, with consistency similar to the intestine, and easy to use in the laparoscopic simulation environment. Materials and methods: A descriptive observational study was carried out with 25 laparoscopic surgeons who evaluated the mentioned tissue through laparoscopic suturing and knotting, by means of a semi-structured perception survey. Results: The overall score of the experience had a median of 9 on a visual analog scale from 0 to 10 in regard to the specific characteristics of the tissue, the perception that it allows a simple and continuous suture to be performed easily, was 68% (n = 17) and 52% (n = 13) respectively, and to perform laparoscopic intracorporeal knotting with much ease was 76% (n = 19). Conclusion: the proposed tissue fulfills the desired characteristics and provides a useful simulation model to improve the learning of knotting and suturing by laparoscopy.
