迄今手术切除仍为肝癌的主要疗法,但在肝两叶多发肿瘤、肝储备功能不佳、邻近大血管的肿瘤以及病人情况恶劣者则无法进行手术切除。对此,作者采用冷冻疗法,经右肋下切口进行探查,确诊无肝外病变,游离肝周围韧带。术中作 B 超扫描协助定位。取8mm、10mm 或12mm 冷冻探头,其中循环液氯,低温达-196℃。将探头插入肿瘤中心(在 B 超引导下)。一般冷冻部位的冰冻一解冻周期为冰冻8分钟和解冻15～20分钟,每一病灶施行2～3周期。要保护好肝脏周围脏器,免受损伤。探头刺入管道用明胶海填塞以减少出血。
To date, surgical resection remains the main treatment for liver cancer, but tumors with multiple tumors in the two livers, poor liver reserve, tumors adjacent to large blood vessels, and poor patient conditions cannot undergo surgical resection. In this regard, the author used cryotherapy, exploration through the right subcostal incision, confirmed no extrahepatic lesions, free ligament around the liver. Intraoperative B-scan to assist in positioning. Take a 8mm, 10mm, or 12mm cryoprobe, with circulating chlorine, at a low temperature of -196°C. Insert the probe into the center of the tumor (under Ultrasound B guidance). The freezing-thawing cycle of the general freezing site is freezing for 8 minutes and thawing for 15-20 minutes, and each lesion is performed for 2 to 3 cycles. Protect the organs around the liver from damage. The probe pierces the tube and is filled with gelatin sea to reduce bleeding.
