Abstract
Use of laparoscopic techniques for resection of colon and rectal cancer has raised considerable controversy. There is increasing concern that wound recurrence and peritoneal dissemination may represent a potentially fatal complication of this technique. The surgical literature was reviewed, and clinical course of two patients is presented. Our two patients had tumor recurrence in the laparoscopy port sites within one year after laparoscopic-assisted colectomy for Dukes B adenocarcinoma of the colon. At laparotomy, diffuse peritoneal carcinomatosis without lymph node or liver metastases were found in both patients. They were treated by surgical resection of recurrent disease combined with heated intraoperative intraperitoneal mitomycin C chemotherapy and five days of early postoperative intraperitoneal 5-fluorouracil. These patients are clinically free of disease at 1.5 years after treatment of peritoneal implants. Cancer recurrence in abdominal wall incisions after laparoscopic colectomy has been reported in an increasing number of patients. It is possible that this technique should be abandoned. Cytoreductive surgery combined with intraperitoneal chemotherapy may represent the most adequate treatment of recurrent cancer that occurs following laparoscopic colectomy.
