对包括有转移的肝肿瘤,施行肝切除手术已成为积极的疗法。但是,当考虑有慢性肝炎、肝硬变等合併症时,肝切除范围的大小即受到很大限制。从缩小手术切除范围和简化手术的角度出发,肝的冷冻治疗已试用于临床,今概略报告如下:肝冷冻疗法分接触和穿刺两种,以穿刺法更有利,作者采用了穿刺法。使用穿刺法能造成直径为4～4.8厘米的较大冰冻范围,在该范围内能产生冻结坏 For liver tumors that include metastases, liver resection has become an active therapy. However, when considering complications such as chronic hepatitis, cirrhosis, etc., the size of the hepatectomy range is greatly limited. From the perspective of reducing the extent of surgical resection and simplifying the operation, cryotherapy of the liver has been used in clinical trials. The summary report is as follows: Liver cryotherapy consists of two types: contact and puncture. The puncture method is more favorable. The author adopted the puncture method. The puncture method can cause a large frozen area with a diameter of 4 to 4.8 centimeters. In this range, it can cause freezing damage.
