Background: Cervical cancer is a common malignant tumor in women. This study aims to explore the clinical effects of traditional laparotomy, extensive vaginal hysterectomy and laparoscope-assisted vaginal hysterectomy in the treatment of patients with cervical intraepithelial neoplasia III (CIN III).Methods: A total of 79 cases with CIN III in situ who were treated in our hospital from July 2015 to February 2017 were selected as the study participants. According to the different surgical methods employed, patients were divided into a laparotomy group (n=21), a vaginal group (n=26), and a laparoscope-assisted vaginal group (n=32). The operative indicators in the three groups were compared, as well as the operative complications, quality of life, and female sexual function.Results: The operation time, intraoperative blood loss, and hospitalization time in the laparotomy group were all significantly greater than those in the vaginal and laparoscope-assisted vaginal groups (P<0.05), and the operative time was the shortest in the vaginal group. There was no significant difference in postoperative recovery time, drainage tube removal time, and time to out-of-bed activation between the vaginal group and the laparoscope-assisted vaginal group (P>0.05). After surgery, the main complications were poor wound healing, infection, vaginal discharge, and neoplasms of the vagina, and the total incidence of complications in the laparotomy group was 19.04%, which was significantly higher than that in the vaginal group (3.84%) and the laparoscope-assisted vaginal group (3.12%) (P<0.05). Three months after surgery, the physical and emotional function scores of patients in the laparoscope-assisted vaginal group were significantly higher than those in the laparotomy and vaginal groups (P<0.05). Six months after surgery, there were no significant differences among the three groups in scores of libido, sexual intercourse pain, orgasm, or difficulty in sexual intercourse (P>0.05).Conclusions: Laparoscope-assisted vaginal hysterectomy has a short recovery time and a low incidence of complications in patients with early cervical cancer in situ. Compared with laparotomy and vaginal hysterectomy, laparoscope-assisted vaginal hysterectomy is more conducive to improving the postoperative quality of life of patients.
