[Tumor seeding on trocar scars: epidemiology, clinical significance and prevention]

A comprehensive literature review was conducted to study the epidemiology, clinical significance and preventive measures for port site recurrence following laparoscopic procedures performed for a colorectal or unrecognised gallbladder cancers. The incidence of this complication is difficult to evaluate, it is estimated in most large current series at about 1% after colorectal resections. Parietal recurrence involves a definite poor prognosis. But it is not demonstrated whether this is due to a worsening of a curable disease or to a disease with an initially poor prognosis. Since this complication has a multifactorial pathogenesis, preventive measures are multiple mainly a rigorous surgical technique according to a prospective operative protocol.
