26 patients suffering from nonresectable adeno-carcinoma of the rectum have been treated since Sept. 1980. The mean age was 72 years. The temperature of the probe tip was -160 degrees C. A closed system with liquid nitrogen was used. In 12 patients there was an indication of systemic inoperability, 13 had an irremovable tumour or metastases. 1 patient refused curative operation. Cryosurgery was aimed at reducing the mass of rectal tumours and preventing colostomy. Colostomy could also be avoided in 12 of 14 patients suffering from stenosing tumours. The advantages of cryotherapy are outpatient treatment, no anaesthesia and minimal complications. Generally, this method will yield good results in palliative treatment of inoperable rectal carcinomata.
自1980年9月以来，对26例无法切除的直肠腺癌患者进行了治疗。平均年龄为72岁。探头尖端温度为-160摄氏度。使用了带有液氮的封闭系统。12例患者存在全身不可手术的指征，13例有无法切除的肿瘤或转移灶。1例患者拒绝根治性手术。冷冻手术旨在缩小直肠肿瘤体积并避免结肠造口术。在14例患有狭窄性肿瘤的患者中，有12例也避免了结肠造口术。冷冻疗法的优点是门诊治疗、无需麻醉且并发症极少。一般来说，这种方法在无法手术的直肠癌姑息治疗中会取得良好效果。
