本文报告我院1982年3月～1984年2月开展冷冻综合治疗直肠癌14例的初步体会。我们应用山东淄博生产的OZ-4型超低温治疗机。低腰或骶管麻醉后先用手指扩肛,选择大小适当的冷冻头。每次冷冻3～5分钟,每次治疗需要3个冻融周期,间隔10～20分钟,作为自然复温时间。若肠腔已狭窄,应先在其底部冷冻,逐渐向上段冷冻。 This article reports the preliminary experience of 14 cases of rectal cancer treated by frozen comprehensive treatment in our hospital from March 1982 to February 1984. We use the OZ-4 ultra-low temperature therapeutic machine produced by Shandong Zibo. Anesthetize the anus with a finger after low-waist or fistula anesthesia, and select the appropriate size of the head. Each frozen 3 to 5 minutes, each treatment requires 3 freeze-thaw cycles, interval 10 to 20 minutes, as a natural rewarming time. If the intestine is narrow, it should be frozen at the bottom and gradually frozen up.
