  1. Laparoscopic-assisted colectomy learning curve.

    Article - En anglais


    The purpose of this paper is to establish the number of cases necessary to master laparoscopic removal of the left or right colon.


    Data were obtained by chart review and by individually completed questionnaires.


    A total of 144 laparoscopic-assisted or intracorporeal right or left hemicolectomies were completed by four surgeons at separate institutions.

    Questionnaires were completed by each surgeon for each sequential hemicolectomy, and data concerning the type of surgery and total operating time were recorded.

    Times were plotted to diagram individual learning curves for each surgeon, and data grouping methods were used to determine the curve for each surgeon as well as for the combined data base.

    Learning was said to have been completed when the surgeon's operative time reached a low point and subsequently did not vary by more than 30 minutes.

    A total of 78 right colectomies and 66 left colectomies were completed by the group.

    Respectively, each surgeon appeared to learn the procedure after 16,21,11, and 6 cases.

    When the entire database was analyzed as a whole, it was shown that between 11 and 15 completed colectomies were needed for learning, after which operative times remained relatively stable.


    This analysis, using total operative time as an indication of learning, shows that approximately 11 to 15 completed laparoscopic colectomies are needed to comfortably learn this procedure.
