作者1982年开始研究超声波导寻呼穿刺-肝癌局部酒精注射疗法(Percutaneous ethanol inject-ion PEI),认为此法可作为小于3cm小肝癌的根治疗法。酒精注射后能浸润至肿瘤周围,造成坏死,以瘤体直径<3cm的肝癌为宜。多灶性肝癌不宜采用。除严重肝衰竭患者外均适用,但有高度腹水者应在腹水消退后进行。方法:1.用一般超声探头确定穿刺目标及途径,尽可能在平静呼吸状态下定位,注意不伤及肺、胆囊及胃肠;2.穿刺点局部消毒,井用1%普鲁卡因局麻;3.用穿刺探头再次定位;4.明确显示病灶
In 1982, the authors began to study ultrasound-guided percutaneous ethanol inject-ion (PEI), which is considered to be a root therapy for small hepatocellular carcinoma less than 3cm. After alcohol injection, it can infiltrate into the tumor and cause necrosis. It is appropriate to use liver cancer with a tumor diameter less than 3cm. Multifocal liver cancer should not be used. All patients except severe hepatic failure are eligible, but those with high ascites should be performed after ascites subsides. Methods: 1. Use a general ultrasound probe to determine the target and method of puncture, position as much as possible in a calm breathing state, pay attention not to hurt the lungs, gallbladder, and gastrointestinal tract; 2. Disinfection at the puncture site, using a 1% procaine station Hemp; 3. repositioning with a puncture probe; 4. clearly showing the lesion
