Colorectal liver metastasis (CRLM) is the most common lesion diagnosed in the liver worldwide and new therapies have been proposed over the last decades. On the leading edge of these therapies, radiofrequency ablation (RFA) has been increasingly applied for treatment these lesions. The procedure can be done by percutaneous approach guided by CT, or during open or laparoscopic surgery. Although findings in preliminary reports suggest that this procedure is both safe and effective, only a few studies have been published. We present a 69-year-old female, previously submitted to two hepatic resections and one RFA for treatment of CRLM, who developed an abdominal wall recurrence due to neoplastic seeding after RFA procedure. In the published literature thus far, some risk factors have been associated with neoplastic seeding following RFA, like subcapsular location, multiple electrode placements, multiple RFA treatments and poor tumor differentiation grade. Technical features like access through normal liver substance and tract needle ablation may play a role in mitigating the risk of this complication. Although it seems to be a safe procedure, only a few retrospective papers have been published its rare complications and outcomes. Nevertheless, patients with localized disease may benefit from surgical resection. |
