Intensive laparoscopic training: the impact of a simplified pelvic-trainer model for the urethrovesical anastomosis on the learning curve.

We prospectively evaluated the learning curve (LC) for laparoscopic urethrovesical anastomosis (L-UVA) in an operator-training model and program using an innovative simplified pelvic-trainer model. Over a period of 12 months, 30 LRP were performed by one urologist skilled in open surgery but inexperienced in laparoscopy. During the first 15 procedures no systematic training was done. Consequentially, a systematic simplified daily program was performed on the pelvic trainer with a videolaparoscopic unit. The training lesson consisted of intracorporal knotting and suturing, linear and circular interrupted suture anastomosis. At the end of each lesson, time and performance error scores were recorded and progression curve was plotted for each task. The performances of each training tasks were plotted against the performance of L-UVA during the LRP. The significance of progression was evaluated using logarithmic regression analysis. A steady improvement in time and accuracy of performance skill was shown during the first 20 lessons (p<0.001). These improved skill acquisitions were proportionally correlated with the time and the accuracy (water-tight) of L-UVA performance during the last 15 L-RPE. Compared to the first 15 L-RPE, where no systematic training was performed, time and accuracy of L-UVA performance in the last 15 L-RPE were improved from a mean 51 (median 48, range: 38-75) to 26 (median 24, range 18-33) min (p<0.001) and from 10 to 15 watertight anastomoses (p<0.001), respectively. Using a continuing, systematic, simplified training model the LC of L-UVA can be improved significantly in a short time.
