Laparoscopy and Colon Cancer

Abstract

Purpose: To quantify the magnitude of the risk for port/extraction site recurrence of laparoscopically resected colon cancer in a defined study population. Methods: The data from a prospective laparoscopic bowel surgery registry was used to identify cases of colon cancer that were resected laparoscopically, with a minimum follow-up of 1 year. A questionnaire was sent to the surgeons who performed the procedures. Results: A total of 252 cases were identified from the registry. Questionnaires were returned in 208 of those cases, a response rate of 82.5%. Three cases of port or extraction site recurrence were noted, two of them associated with diffuse peritoneal carcinomatosis. All the patients had a Dukes' stage C tumor at the time of initial surgery. Conclusions: The incidence of port/extraction site recurrence following laparoscopic colon cancer surgery is low. All the recurrences were in patients with Dukes' stage C tumors, and there was diffuse peritoneal carcinomatosis in two of the three cases, suggesting that port/extraction site recurrence may be attributable to the advanced nature of the disease rather than the laparoscopic technique. Longer follow-up and more cases are required to confirm these findings. (Arch Surg. 1994;129:897-899)
