During the last 8 years, 327 patients with colorectal cancer (Dukes A: 245; B: 38; C: 39; D: 5) underwent laparoscopic colectomy. Median follow-up was 37 months (1∼97 months), and median hospital stay 8 days. Postoperative complications occurring in 36 patients (11.0%) included wound sepsis in 14 (4.3%). Of 322 curative cases, 9 developed recurrence. Of these, 3 with pT3 tumors and 1 with a pT4 tumor had peritoneal recurrence. The Kaplan-Meier method showed 5-year overall survival was 99.3% for Dukes A, 100% for Dukes B, and 79.3% for Dukes C. Long-term results of laparoscopic surgery in patients with early colorectal cancer were thus favorable, but strict follow-up is required in those with pT3 tumors.
