对于手术不能切除的肝脏肿瘤至今没有理想的治疗方法。作者采用液氮冷冻方法治疗外科手术不能切除的肝脏肿瘤,收到了与手术相似的治疗效果。 病人和方法:自1992年1月至1995年4月,共有58例肝脏肿瘤患者准备实施冷冻治疗。男女各半,平均年龄61岁(35～81)。术前诊断主要依靠CT扫描及腹部B型超声。所有患者均行腹腔镜检查或/和剖腹探查。14例(24％)发现肝脏肿瘤范围太广泛或侵犯肝外器官无法分离而放弃冷冻治疗。5例(9％)证实其肿瘤位于肝脏一叶而施行手术切除。其余39例(67％)进行了冷冻治疗。其中包括结肠癌肝转移25例,胃癌肝转移3例,肝细胞癌4例,类癌瘤6例及胃肉瘤肝转移1例。治疗应用Cryotech LCS2000型液氮冷冻机。利用术中超声定位,设置肿
There is no ideal treatment for unresectable liver tumors. The authors used a liquid nitrogen freezing method to treat liver tumors that could not be removed by surgery and received treatment similar to surgery. Patients and Methods: From January 1992 to April 1995, a total of 58 patients with liver tumors were prepared for cryotherapy. Half of men and women, average age 61 (35-81). Preoperative diagnosis mainly depends on CT scan and abdominal B-mode ultrasound. All patients underwent laparoscopy or/and laparotomy. In 14 patients (24%), liver tumors were found to be too extensive or invade extrahepatic organs and abandon cryotherapy. Five patients (9%) confirmed that the tumor was located on the liver and surgical resection was performed. The remaining 39 patients (67%) received cryotherapy. Including 25 cases of colon cancer liver metastases, 3 cases of gastric cancer liver metastases, 4 cases of hepatocellular carcinoma, 6 cases of carcinoid tumors and 1 case of liver metastases of gastric sarcoma. The therapeutic application is a Cryotech LCS2000 Liquid Nitrogen Freezer. Intraoperative ultrasound positioning, setting up the swollen
