当前已公认多数宫颈非典型增生和原位癌的患者会发展成浸润癌因而强调要尽早发现不同阶段的富颈上皮内新生物以采取适当治疗的重要性。本文为对170名妇女因宫颈非典型增生或原位癌用冷冻术治疗的效果进行5～8年随访后的回顾性探讨。研究对象系1972～1974年间用冷冻治疗的宫颈非典型增生或原位癌病人。因多次阴道刮片阳性而就诊。每例患者,治疗前的病理组织学诊断是以宫颈活检和颈管刮术来确定。宫颈阴道部和颈管分别用按这两种不同解剖形状而专门设计的器械治疗,以液氮作冷冻剂,温度在～170°～-190℃。每个部位冻两次,每次30秒,两次之间解冻3分钟。冷冻术在门诊施行,用宫颈旁阻滞麻醉。治疗后即刻或当天就可恢复工作。全部患者在1～3,6,12个月作阴道刮片。然后每年检查一次。如果患者呈持续性细胞学异常型,则施行宫颈活检和颈
It is currently recognized that most patients with cervical atypical hyperplasia and carcinoma in situ develop invasive cancer and thus emphasize the importance of early detection of different stages of neoplastic cervicovaginal neoplasms for appropriate treatment. This article is a retrospective study of 170 women treated with cervical atypical hyperplasia or in situ carcinoma with cryotherapy for 5-8 years follow-up. The study was performed on patients with cervical dysplasia or carcinoma in situ treated with cryotherapy from 1972 to 1974. Due to multiple vaginal smear positive and treatment. In each patient, the histopathological diagnosis before treatment was confirmed by cervical biopsy and neck dissection. Cervix vagina and neck were treated with these two different anatomical shapes and specially designed equipment to liquid nitrogen as a refrigerant at a temperature of ~ 170 ° ~ -190 ℃. Freeze twice a day for 30 seconds each, thaw for 3 minutes between two. Cryotherapy in the clinic, with cervical paralysis anesthesia. Work immediately after or immediately after treatment. All patients in 1 ~ 3,6,12 months for vaginal smears. Then check once a year. If the patient has a persistent cytological abnormality, perform a cervical biopsy and neck
