Abstract:
Objective:To investigate the safety, efficacy and the key points of ultrasound-guided percutaneous radiofrequency ablation (RFA) in treatment of caudate lobe liver tumor.
Methods:The clinical data of 30 patients with caudate lobe liver tumor (57 lesions, 33 caudate lobe lesions) in the Affiliated Tumor Hospital of Zhengzhou University from January 2017 to December 2018 were retrospectively analyzed. All the patients were treated with ultrasound-guided percutaneous radiofrequency ablation. The puncture approach and single-needle or double-needle radiofrequency ablation were chosen according to the lesion location. The efficacy after treatment was evaluated according to the imaging examination. The deadline of follow-up was January 31, 2019, and the median follow-up time was 10 (1 to 20) months. After ablation, CT/MR was performed to evaluate whether the lesions were completely ablated. The effect of treatment and short-term complication were recorded.
Results:Thirty patients were successfully treated with ultrasound-guided percutaneous radiofrequency ablation. Among the 33 caudate lobe lesions, complete ablation rate at one time was 81.8% (27/33); local tumor progression rate after treatment was 12.1% (4/33), and the median time was 2.5 months. The new lesion rate was 26.7% (8/30), and the median time was 3.0 months. Two patients had significant abdominal pain, 1 patient had fever, 1 patient had hypoxemia during the ablation, and total incidence of complication was 13.3% (4/30). There was no bile leakage, gastrointestinal tract injury, uncontrollable bleeding and other serious complications and related deaths.
Conclusions:For the caudate lobe liver tumor, ultrasound-guided percutaneous radiofrequency ablation is safe and effective. It is necessary to select the appropriate puncture approach, avoid the intrahepatic duct reasonably and master the key points of ablation.
