ABSTRACT
BACKGROUND/AIMS:
Rates of postoperative complications after radiofrequency ablation (RFA) remain high for patients who have previously undergone surgery associated with the bile duct. Our purpose is to clarify the rate of postoperative complication and identify preoperative risk factors.METHODOLOGY:
This retrospective study reviewed patient backgrounds, ablation areas, and preoperative laboratory data in 8 patients (9 tumors) who underwent RFA after enterobiliary anastomosis.RESULTS:
Postoperative complications occurred in 6 of the 8 cases (75%). Postoperative liver abscesses occurred in both the cases of tumor located in the hepatic hilum, i.e., tumor located 530 mm from the site of enterobiliary anastomosis. Of the 6 patients with peripherally located tumors, postoperative liver abscesses occurred in 4 patients with elevated preoperative levels of alkaline phosphate (ALP), 3 of whom required abscess drainage. No postoperative complications occurred in the 2 patients with tumors located in the periphery of the liver and with normal preoperative ALP levels.CONCLUSIONS:
Postoperative complications are frequent when RFA is performed in patients who have previously undergone enterobiliary anastomosis. These results suggest that RFA after enterobiliary anastomosis should not be recommended. However, the risk may be lower in cases where the nodules are located in the liver periphery and the preoperative ALP level is low.
