作者就经皮注入酒精(PEI)治疗小肝癌的效果,特别是长期疗效及治疗后肝内非治疗部复发等问题作了研究。使用外径0.7mm、长15cm穿刺针,在局部超声波引导下穿刺肿瘤,并注入99.5％的无菌酒精和1％的普鲁卡因。酒精的注入量依肿瘤大小而定,一般一个注射点2～6ml,每周一次共行4～6次。PEI适应证是超声波显示出的直径3cm以下、3个病灶以下且无严重肝功能障碍的肝细胞癌。共对97例、117个病灶行PEI,平均年龄58岁,
The authors studied the effect of percutaneous injection of alcohol (PEI) on the treatment of small hepatocellular carcinoma, especially the long-term efficacy and recurrence of non-hepatic intrahepatic treatment after treatment. Using a puncture needle with an outer diameter of 0.7 mm and a length of 15 cm, the tumor was punctured with local ultrasound guidance, and 99.5% of sterile alcohol and 1% of procaine were injected. The amount of alcohol injected depends on the size of the tumor. Generally, one injection point is 2-6ml, and once a week, it is 4-6 times. The PEI indication is hepatocellular carcinoma with a diameter of 3 cm or less, less than 3 lesions, and no severe hepatic dysfunction, as demonstrated by ultrasound. A total of 97 patients and 117 lesions underwent PEI, with an average age of 58 years.
