    Laparoscopic colorectal surgery for cancer is currently under discussion.

    Results of large, randomized studies will not be available for a number of years yet.

    This study analyses the results of such resections in consecutive patients operated on by unselected surgeons.


    A prospective, observational, multicenter study was initiated on August 1,1995, in the German-speaking countries of Europe.

    One year after initiation of the study, findings are presented with respect to the quality of oncologic resections.


    Of 500 operations, 231 (46 percent) were performed for cancer, 167 (33 percent) with a curative intent.

    The most common curative resections were as follows : 63 anterior rectum resections (38 percent), 51 sigmoid resections (30 percent), and 27 abdominoperineal resections (16 percent).

    Segmental resections were performed in 20 patients (12 percent).

    Intraoperative tumor spillage was reported in 2 percent.

    Mean number of lymph nodes harvested was 13 (confidence interval, 5-95 percent ; range, 11.5-14.6) and positive lymph nodes harvested was 2.2 (confidence interval, 5-95 percent ; range, 0.9-3.4).

    Significant differences were noted between participating centers in terms of number of lymph nodes resected (P<0.0001).

    Distal and proximal resection margins were tumor-free in every case.

    Lateral margins were tumor-free when examined. (...)
