我院利用液氮超低温冷冻加工手术治疗肺部肿瘤51例。所用术式有三:1)冷冻楔形切除;2)补充冷冻;3)单纯冷冻。本文较详细介绍了手术方法。本组腺癌31例;鳞癌14例;鳞癌混合癌1例;肺部转移瘤5例。本组原发肺癌术后随访一年以上38例,取同时期非冷冻手术治疗之原发肺癌为 In our hospital, 51 cases of lung tumors were treated with ultra-low temperature liquid nitrogen cryosurgery. There are three surgical methods used: 1) cryogenic wedge resection; 2) supplemental freezing; 3) simple freezing. This article describes the surgical method in more detail. This group of 31 cases of adenocarcinoma; squamous cell carcinoma in 14 cases; squamous cell carcinoma mixed in 1 case; pulmonary metastases in 5 cases. The primary lung cancer in this group was followed up for more than one year after surgery in 38 patients. The primary lung cancer treated with non-frozen surgery at the same time was
