Abdominal wall metastasis and peritoneal carcinomatosis after laparoscopic-assisted colectomy for colon cancer.

We report a case of a port-site recurrence with diffuse peritoneal carcinomatosis after laparoscopic-assisted right hemicolectomy. The interval between resection of the colonic adenocarcinoma and diagnosis of the recurrence was short (1 month), suggesting that intraperitoneal dissemination and tumour implantation on surgical wounds may represent the principal mechanism of recurrence after laparoscopic surgery. Review of the literature shows an alarming increase in the occurrence of this devastating complication. Although beneficial to the patient in the immediate post-operative period, the adequacy of laparoscopic-assisted colectomy in tumour is increasingly under question.
