RESUMO
BACKGROUND: The role of laparoscopic colon resection in the management of colon cancer is unclear. The aims of this study were to compare perioperative results and long-term outcomes in patients randomized to either open (O) or laparoscopically assisted (LA) colon resection for colon cancer. METHODS: A prospective randomized trial comparing O to LA colon resection was conducted from January 1993 to November 1995. Preoperative workup, intraoperative results, complications, length of stay, pathologic findings, and long-term outcomes were compared between the two groups. Statistical analysis was performed with t-test. Follow-up periods ranged from 3.5 to 6.3 years (mean, 4.9 years). RESULTS: No port-site or abdominal wall recurrences were noted in any patients. [table: see text] CONCLUSIONS: These results suggest that laparoscopically assisted colon resection for malignant disease can be performed safely, with morbidity, mortality, and en bloc resections comparable with those of open laparotomy. Long-term (5-year) follow-up assessment shows similar outcomes in both groups of patients, demonstrating definite perioperative advantages with LA surgery and no perioperative or long-term disadvantages.
