This study assessed the efficacy and safety of artificial ascites in assisting ultrasound-guided percutaneous microwave (MW) ablation of hepatic tumours adjacent to the gastrointestinal tract.
In total, 36 patients with 36 hepatic malignancies who underwent the introduction of artificial ascites before ultrasound-guided percutaneous MW ablation were included in this retrospective study. The separation success rate of the artificial ascites, the technique effectiveness of the MW ablation, local tumour progression and complications were assessed.
The separation success rate of the artificial ascites for 36 hepatic tumours adjacent to the gastrointestinal tract was 88.9% (32/36). The technical effectiveness of MW ablation in 32 cases with successful separation was 96.9% (31/32). During follow-up (mean, 12.1 ± 7.2 months), local tumour progression was found in five of 31 patients (16.1%). One patient experienced a major complication (infection of the hepatic ablation zone).
Ultrasound-guided percutaneous MW ablation assisted by artificial ascites is a safe and effective method for the treatment of primary and metastatic hepatic tumours adjacent to the gastrointestinal tract and can achieve good local control of such tumours.
本研究评估人工腹水辅助超声引导下经皮微波（MW）消融治疗胃肠道毗邻肝肿瘤的疗效和安全性。
本回顾性研究共纳入36例患有36个肝恶性肿瘤且在超声引导下经皮MW消融前引入人工腹水的患者。评估人工腹水的分离成功率、MW消融的技术有效性、局部肿瘤进展及并发症情况。
36个胃肠道毗邻肝肿瘤的人工腹水分离成功率为88.9%（32/36）。32例分离成功病例中MW消融的技术有效性为96.9%（31/32）。随访期间（平均12.1±7.2个月），31例患者中有5例（16.1%）出现局部肿瘤进展。1例患者发生严重并发症（肝消融区感染）。
人工腹水辅助超声引导下经皮MW消融是治疗胃肠道毗邻原发性和转移性肝肿瘤的一种安全有效的方法，可实现对此类肿瘤的良好局部控制。
