应用液氮作为致冷物质而产生的深低温治疗各种疾病,是近十余年来的新发展。自1983年以来,我院应用液氮治疗阴茎头部乳头状肿瘤3例,取得满意效果。方法采用液氮接触法冷冻,每次2分钟,待局部形成黄白色冰球后,自然复温,此为一个“冻融”循环。每例进行3个“冻融”循环。例1 40岁,农民。阴茎冠状沟背侧有一1.5×1.5×0.3cm 暗红色乳头状分叶肿物。冷冻后肿瘤5天干燥缩小,呈黑褐色,12天全部脱落。随访3年,局部肤色正常,柔软无硬结。例2 18岁,学生。阴茎腹侧包皮系带两旁有3个肿物,直径分别为1.5、0.5和0.3cm,扁平状,
The application of liquid nitrogen as a cryogenic substance in the treatment of various diseases caused by deep hypothermia is a new development in the past ten years. Since 1983, our hospital liquid nitrogen treatment of penile head papillary tumors in 3 cases, and achieved satisfactory results. Methods The liquid nitrogen contact method was used to freeze for 2 minutes each time. After forming the yellow-white ice puck locally, the body was naturally rewarmed. This is a “freeze-thaw” cycle. Three “freeze-thaw” cycles are performed for each case. Example 1 40-year-old farmer. Coronal dorsal penis has a 1.5 × 1.5 × 0.3cm dark red papillary lobe tumor. Frozen tumor shrinks after 5 days, dark brown, 12 days all off. Followed up for 3 years, local skin color normal, soft without induration. Example 2 18 years old, student. Penile ventral foreskin ligament on both sides of 3 tumor, the diameter was 1.5, 0.5 and 0.3cm, flat,
