超声内镜引导无水酒精治疗特殊部位肝癌10例

目的评价超声内镜引导无水酒精消融治疗特殊部位肝癌的可行性、安全性及有效性。方法 2010年3～12月对10例复发性肝癌患者共10个复发病灶进行超声内镜引导无水酒精消融治疗。所有患者术前均行超声造影、增强CT及超声内镜扫描。增强CT及超声内镜可显示所有病灶,而超声造影仅显示9个病灶。10个病灶中有5个病灶位于肝尾状叶,3个病灶位于肝门部,2个病灶位于腹膜后。病灶最大径为1.8～3.2cm,平均为(2.5±0.6)cm。结果使用超声内镜引导,对10例复发性肝癌患者共10个复发病灶均成功进行无水酒精注射,无水酒精注射量为20～30mL,平均为(25.0±4.1)mL。无治疗相关并发症。术后1个月增强影像学评价,经单次治疗后肿瘤完全消融率为6/10,4例残留。补充1次治疗后完全消融率为9/10。截至2011年4月,1个病灶发生局部肿瘤进展。此复发病灶接受了超声造影引导下经皮cool-tip射频消融。结论超声内镜引导无水酒精消融治疗是一种安全有效的治疗方法,尤其对位于肝尾状叶、肝门部及腹膜后等特殊部位的肿瘤可作为一种微创的可替代疗法。

Initial clinical experience of ethanol ablation with endoscopic ultrasonography guidance for 10 cases of hepatocellular carcinoma which are difficult to reach by percutaneous mode

Objective To evaluate the feasibility,safety and effectiveness of endoscopic ultrasonography (EUS) for guiding ethanol ablation (EA) for hepatocellular carcinoma (HCC) lesions, which are difficult to be treated by percutaneous ablation. Methods Ten patients with recurrent HCC were enrolled in the study with ten HCC lesions located in caudate lobe( n=5), hepatic hilum( n=3), or retroperitoneum ( n=2). All patients underwent contrast-enhanced ultrasonography (CEUS) scanning, contrast-enhanced CT (CECT) scanni...
