Influence of Previous Experience on the Benefits of Laparoscopic Surgical Training Based on Simulation
2019
Abstract Introduction Surgical training based on simulation seeks the acquisition of skills in novice participants and ongoing skill development in experts. The aim of this study is to assess the evolution of students in an intensive laparoscopic anastomosis course and to analyze their results depending on their level and previous experience. Methods The students of all the anastomosis courses conducted during 30 months in the Valdecilla virtual hospital (Santander) were analyzed. Manual side-to-side intestinal anastomoses with porcine ‘ex vivo’ viscera were performed in a laparoscopic endotrainer. The technical and quality differences between the first and the last anastomoses were analyzed and the progression between residents and specialists was compared. Results We analyzed 45 participants, 22 of them residents and 23 specialists. A statistically significant improvement of 80.5% was observed in all procedural parameters (94.8% residents vs. 67.3% specialists). The time was reduced by 48.1% in the residents and 43.2% in the specialists ( P In terms of quality, significant improvements were obtained in the group of residents: an increase of 90% in adequate tension, and a reduction of 75% of everted edges and 60% of leaks. In addition, they obtained results comparable to the specialists (27.3% leak in the last anastomosis vs. 34.8% by the specialists, P =.59), which presented improvement without statistical significance. Conclusions The group of residents presented a major and significant improvement in procedural skills and in the quality of the technique, reaching the level of the specialists after completion of the course.
