Laparoscopic radiofrequency ablation (RFA) is gaining increasing acceptance as a treatment option for primary and secondary liver tumors with minimal morbidity. The purpose of this study is to see if adding a colorectal procedure to RFA increases the risk of hepatic abscess. Of the 310 patients with 1,080 primary and secondary liver tumors undergoing laparoscopic radiofrequency ablation (RFA), 16 patients underwent RFA in combination with various colorectal procedures. Data were collected prospectively. The concomitant procedures included loop ileostomy closures in 6 patients; laparoscopic-assisted right hemicolectomy in 3 patients; laparoscopic-assisted anterior resection in 2 patients; and open transverse colectomy, open anterior resection, open low anterior resection, open loop transverse colostomy formation, and anal stricture dilatation in 1 patient each. Mean ± SD hospital stay was 2.9 ± 1.7 days. There was no mortality, and the only complication was the development of a right flank abscess after laparoscopic-assisted right hemicolectomy that was treated with percutaneous drainage. Although patients undergoing laparoscopic RFA in combination with a clean-contaminated procedure could be at high risk for secondary infection of ablated foci, this was not observed. This approach is safe and does not impair recovery from either procedure. These data support the concept that RFA may be safely used with concomitant colon resections to treat liver metastases that may be resectable but are associated with increased morbidity if resected synchronously.
