The Heilbronn laparoscopic training program for laparoscopic suturing: concept and validation.
OBJECTIVE
More than a decade after the first description of laparoscopic nephrectomy, an increasing number of laparoscopic procedures are being performed worldwide. Nevertheless, there still exists a significant lack of standardized training programs to teach ablative and, most important, reconstructive laparoscopic operations (i.e., pyeloplasty, radical prostatectomy). We evaluated and validated a new standardized step-by-step program to improve laparoscopic skills and enable trainees not experienced in laparoscopy to perform a urethrovesical anastomosis.


METHODS
In an inanimate model (pelvic trainer) with defined trocar positions, the 10 participants were exposed to six reconstructive exercises. The steps consist of improvement of hand-eye coordination (two-row metal-pin model; step I), linear and curved suturing with changing angles of the needle (chicken leg and catheter model; steps II-V), and performance of an anastomosis in a porcine bladder (step VI). Times of 3, 15, 15, 10, 20, and 30 minutes for steps I, II, III, IV,V, and VI, respectively, were defined as the goal before proceeding to the next stage. The time required to succeed in each step and the increase in the speed of suturing and knotting activities were analyzed with the Wilcoxon signed-rank test.


RESULTS
After a mean of 40 hours of training, all participants were able to perform all steps within the specified times and complete an accurate urethrovesical anastomosis in 30 minutes. The time required to succeed before and after training showed a significant decrease (P < 0.05). Continual training in reconstructive procedures decreased the time needed for suturing activities by between 66.3% and 72.2%. The time needed for the knotting activities decreased by between 34.3% and 38.3%.


CONCLUSIONS
Our program enabled participants not experienced in laparoscopy to increase reproducible performance in reconstructive laparoscopy. These results indicate that the challenging parts of reconstructive laparoscopy such as intracorporeal suturing can be taught using a standardized concept. This experience could be incorporated easily by every department developing a laparoscopic training program.
