Objective To explore the value of vaginal extension with peritoneum in the laparoscopic radical hysterectomy with the preservation of pelvic autonomic nerve .Methods Seven cases with cervical carcinoma at the stage of the Ⅰb-Ⅱa had the laparoscopic radical hysterectomy with the preservation of pelvic autonomic nerve and the operation of vaginal extension with peritoneum at the same time.Post-operative vaginal length and sexual life status of the patients were studied .Results The length of vagina 3 months after the operation was 8 to 11cm, with the average length of 8.8 ±2.2cm.No obvious side effect on sex life was found after the surgery . Conclusion It is feasible and advisable that the patients with cervical carcinoma have vaginal extension with peritoneum to ensure their life quality while they have laparoscopic radical hysterectomy with the preservation of the pelvic autonomic nerve .%目的探讨腹膜阴道延长术在腹腔镜下保留盆腔自主神经广泛子宫切除术中的价值。方法对7例Ⅰb～Ⅱa宫颈癌患者在行保留盆腔自主神经广泛性子宫切除术的同时行腹膜阴道延长术，研究患者术后阴道长度、性生活的情况。结果术后3个月测量阴道长度为8～11cm，平均长度为8．8±2．2cm。性生活质量术后与术前相比无明显影响。结论宫颈癌患者在行腹腔镜下保留盆腔自主神经的同时，采用腹膜进行阴道延长是可行的，保证了患者术后的生活质量，值得推广。
