OBJECTIVES: To date the number of procedures required to become competent to perform new laparoscopic surgical techniques is not known.
STUDY DESIGN: The pig model was chosen for assessment of the learning curve associated with an advanced laparoscopic procedure. A unilateral laparoscopic pelvic lymphadenectomy was performed by two residents and a laparoscopic para-aortic lymphadenectomy was performed by a fellow on a series of 20 pigs. The quality of the dissection was checked by immediate laparotomy by an independent observer.
RESULTS: The operative objectives were: (a) There should be less than 5% residual lymph nodes. (b) The operating time should be less than 30 min for pelvic and less than 100 min for para-aortic lymphadenectomy. (c) Avoiding conversion because of complications. This target was achieved after 7 and 9 pigs respectively for pelvic lymphadenectomy and after 14 pigs for para-aortic lymphadenectomy.
CONCLUSION: It is feasible to assess the learning curve of trainee surgeons while performing laparoscopic pelvic and para-aortic lymphadenectomy on pigs. A training programme such as this should prevent complications due to inexperience and should satisfy ethical and medico-legal considerations.
