To our knowledge, this is both the largest and longest follow-up of RFA for colorectal metastases. The number and dominant size of metastases, and preoperative chorioembryonic antigen value are strong predictors of survival. Despite classic teaching, extrahepatic disease did not adversely affect survival. In this group of patients who failed chemotherapy, newer treatment regimens (pre- or postoperatively) had no survival benefit. The actual 5-year survival of 18.4% in these patients versus near zero survival for chemotherapy alone argues for a survival benefit of RFA.

This is the first study to compare 5 year actual recurrence rates between laparoscopic and open ventral hernia repairs. Contrary to prior reports, our longer-term data indicates similar recurrence rates, except for higher rates in the laparoscopic converted to open group. Due to the continued recurrences over the period studied, longer-term follow-up is necessary to appreciate the true rate of hernia recurrence.
