The implantation process seems to be unique to laparoscopic treatment in several ways. The development of recurrent cancer in abdominal scars following oncologic procedures performed through a laparotomy incision is unusual and, like breast cancer recurrence in mastectomy incisions, generally represents systemic dissemination of the disease. Laparoscopy produces port site recurrence in the absence of disseminated disease, and the implantation can become clinically evident virtually within days of the laparoscopic procedure.
