    Abstract:
    AIM OF THE STUDY: To present the early experience of the Authors' division in the field of colorectal laparoscopic surgery, in order to evaluate the so-called "learning curve". MATERIALS AND METHOD: From February 2003 to May 2004, we have performed 220 surgical procedures for colorectal pathology: 63 were conducted by a laparoscopic approach with 10 patients who, converted to a laparotomic procedure in theatre, were not taken under consideration. The present work is thus based on a population of 53 patients, 27 men and 26 women, at a median age of 64.4 y.o. (range 42-81). RESULTS: We performed 1 total colectomy, 24 right hemicolectomy, 1 resection of the splenic flexure, 12 left hemicolectomy (in 1 case a left hepatic lobectomy was associated), 11 anterior resection of the rectum, 1 Hartmann' sigmoid resection and 3 abdomino-perineal resection. Mean operative time was 200.34 +/- 64.17 min, while the mean hospital stay was 6.44 +/- 2.68 days. Peri-operative mortality was 0%, 30-days mortality was 1/53 patients (9%) while morbidity was 5/53 patients (9.4%): in 2 cases reintervention was necessary. DISCUSSION: From the evaluation of the results, we found some significant data: first, the conversion rate was similar to those reported by other authors, so also the mortality and morbidity rates. CONCLUSIONS: The advantages of the laparoscopic technique, indirectly documented by shorter in-hospital stay. At least for patients submitted to right or left hemicolectomy without complications (5.5 e 5.7 days, respectively), could be seen also after only a 1 year of activity. As far as the "learning curve" is concerned, dividing our activity into 3 times, we verified a progressive shortening of the operative time and, at least for the patients submitted to a right emicolecomy, also of the morbidity rates.
