作者施行了12个病例14个病灶超声导向下经皮注射95％乙基酒精治疗,9个病灶是原发性肝细胞癌,4个胃癌肝转移,1个膀胱移行细胞癌腹膜转移,共做了75次注射。治疗的适应证是传统治疗无效或拒绝手术,且超声易于发现的肿物,肿物径线小于5cm。病灶直径小于3.2cm的11例治疗成功率为100％,术后针吸活检恶性肿瘤细胞阴性,100％的 The authors performed 14 lesions in 12 cases with ultrasound-guided percutaneous injection of 95% ethyl alcohol, 9 lesions were primary hepatocellular carcinoma, 4 liver metastases from gastric cancer, and 1 bladder transitional cell carcinoma peritoneal metastasis. 75 injections. Indications for treatment are conventionally ineffective or refusal surgery, and ultrasound is easy to find in the mass, and the diameter of the tumor is less than 5cm. The success rate of 11 cases with lesion diameter less than 3.2cm was 100%. Postoperative needle biopsy was negative for malignant tumor cells, 100%
