Risk of abscess formation after liver tumor radiofrequency ablation: a review of 8 cases wtih a history of enterobiliary anastomosis.

摘要: 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 rate complication and identify preoperative risk factors. METHODOLOGY This retrospective study reviewed patient backgrounds, areas, laboratory data in 8 (9 tumors) underwent RFA enterobiliary anastomosis. RESULTS Postoperative occurred 6 cases (75%). liver abscesses both tumor located hepatic hilum, i.e., 5–30 mm from site Of peripherally tumors, 4 elevated levels alkaline phosphate (ALP), 3 whom required abscess drainage. No 2 tumors periphery normal ALP levels. CONCLUSIONS are frequent when performed These results suggest that anastomosis should not be recommended. However, may lower where nodules level low.
