| Abstract: | Although the incidence of port-site metastasis after laparoscopic surgery for colorectal cancer has markedly decreased since laparoscopic colectomy was first reported in 1991, it still has not reached zero. In colorectal cancer, the safety of laparoscopic surgery, including the low incidence of port-site metastasis, has been proven in large, randomized trials. In gastric cancer, reports of port-site metastasis are extremely rare, but we should await the results of ongoing trials. This brief review summarizes the current knowledge regarding port-site metastasis after laparoscopic surgery for colorectal and gastric cancer. |
