Mechanism of Abdominal Wall Recurrence After Laparoscopic Resection of Colonic Cancers.
Although abdominal wall recurrence after conventional resection for colon cancer remains a rare event, several reports of trocar site recurrence after laparoscopic oncological procedures have been reported. Although the mechanism is unclear, it appears that local factors are important for trocar recurrence after colorectal cancer procedures. Hematogenous dissemination to the trocar site does not appear to be a primary mechanism. The full realization of port-site recurrence has yet to be uncovered because only a relatively small number of colonic resections have performed laparoscopically for cancer. Prospective studies must include opportunities for both the discovery of trocar site recurrence and documenting this entity carefully.
