title: Laparoscopic colectomy in colon cancer. A single-center clinical experience.
abstract: BACKGROUND
  Aim of our study was to compare the results of the laparoscopic technique to those obtained by traditional open approach in patients with colon cancer. The advantages, disadvantages, and the contraindications (real and presumptive) of this mini-invasive approach are described, by comparing the data obtained from the international literature with our clinical experience.
  
  
  METHODS
  From February 2000 to May 2006, we performed 73 laparoscopic colectomies for cancer in the Operative Unit of General and Laparoscopic Surgery, Department of Surgical Sciences of the University of Chieti, Italy. The data of these patients were compared with the data obtained from 141 other patients who underwent open procedure for the same pathology in the same period and in the same Unit. Factors such as obesity, previous major abdominal surgery, T4 cancers, perforation and obstruction of the colon, tumor located in the transverse colon or in the left flexure of the colon were considered contraindications to laparoscopic approach.
  
  
  RESULTS
  The length of surgical specimens and the number of lymph nodes removed did not show significant differences in the two groups. Two patients in the open procedure group died in the postoperative period. No postoperative death was noted in the group of patients operated by laparoscopic method. Postoperative complications requiring re-operation were observed in 9 patients in the open group and in 3 patients of laparoscopic group. Postoperative complications not requiring re-operation were observed in 16 patients in the open group and in 4 patients in laparoscopic group. Hospital stay was shorter for laparoscopic right or left colectomy compared to corresponding open procedures. At the follow-up (a mean 30 months), the overall survival was 78% for open colectomies and 82.1% for laparoscopic colectomies. Disease-free survival, excluding patients with stage IV tumor and patients died in the postoperative period, was 77.6% for open colectomies and 82.5% for laparoscopic colectomies. In the group of laparoscopic patients, we observed 1 case of port-site recurrence.
  
  
  CONCLUSIONS
  Our clinical experience, even if limited by the number of patients and by the duration of follow-up period, contributes in confirming the reliability of laparoscopic procedures in the treatment of tumours of the colon and the safety of oncological results.
