When performing cervical conization in post-menopausal cervical intraepithelial neoplasia 3 (CIN3) patients, the positive rate of endocervical cone margin and the incidence of postoperative cervical stenosis increase. This study summarized a 4-year experience of total laparoscopic hysterectomy as a treatment option for peri-menopausal and post-menopausal CIN3 patients at a single institution. Furthermore, it shared the refinement strategies used during the surgery.


This study retrospectively analyzed the medical records of CIN3 patient aged ≥45 years and who underwent open or laparoscopic hysterectomy at our institution from January 1, 2017 to December 31, 2020. Totally, 30 CIN3 patients were enrolled and divided into abdominal hysterectomy group and laparoscopic hysterectomy based on surgery method, with 5 patients and 25 patients respectively.

Results: Compared to the abdominal hysterectomy group, the perioperative blood loss (20 mL vs. 220 mL, p = 0.004) was less and the duration of in-hospital stay (7 d vs. 11 d, p < 0.001) were significantly shorter in the laparoscopic hysterectomy group. However, no significant differences in age at hysterectomy (53 y vs. 77 y, p = 0.054) and operative time (154.4 ± 27.8 min vs. 161.0 ± 62.4 min, p = 0.826) were observed between them. Diagnostic conization was performed in advance for 12 patients, and among them, 10 (83.3%) patients had positive endocervical cone margin. Postoperative intestinal obstruction was noted in one abdominal hysterectomy patient, no other complications were observed in the remaining patients.


Compared to conization, hysterectomy is more invasive; however, it is an acceptable treatment option for peri-menopausal and post-menopausal CIN3 patients. In such cases, opting for total laparoscopic hysterectomy adopted the marionette technique might be preferable because the procedure is less invasive.
