To investigate the clinical effect of dienogest combined with physical constitution dialectical conditioning for treating patients with ovarian endometriosis operation, and to study its effect on postoperative ovarian function of the patients. Methods: A total of 84 patients who wanted laparoscopic surgery for treating ovarian endometriosis were selected and randomly divided into two groups (42 patients in each group) from January 2019 to August 2021. The patients in both groups were given conventional laparoscopic excision of ovarian endometriosis. The patients in the control group were given dienogest after operation, and the patients in the observation group were given dienogest combined with constitution dialectical conditioning after operation. The treatment effect and physical improvement, the pain degree by numeric rating score (NRS), the levels of ovarian function indexes, such as follicular development status, and the levels of estradiol (E2), luteinizing hormone (LH), and follicle stimulating hormone (FSH), and the adverse reactions rate of the patients were analyzed and compared between the two groups. The recurrence situations of ovarian endometriosis of the patients in the two groups were followed up for 6 months. Results: The total effective rate (97.6%) of the patients in the observation group was significantly higher than that (78.6%) of the patients in the control group (P<0.05). The patients with abdominal pain and irregular vaginal bleeding occurred in both groups, and which were relieved after symptomatic treatment. The recurrence rate (2.4%) of ovarian endometriosis of the patients in the observation group during followed up was significantly lower than that (19.1%) of the patients in the control group (P=0.029). After treatment, the physical constitution improvement of the patients in the observation group was significantly better than that of the patients in the control group. NRS score (3.64±0.49 points), the rates of follicular development atrophy (2.4%) and follicular luteinization (4.8%) of the patients in the observation group were significantly lower than those (5.21±0.61 points, 23.8%, and 21.4%) of the patients in the control group. The sex hormones levels of the patients in the observation group were also significantly lower than those of the patients in the control group (all P<0.05). Conclusion: Dinogest combined with physical constitution dialectical conditioning for treating the patients after the operation of ovarian endometriosis can significantly improve their postoperative treatment effect, relieve their dysmenorrhea, improve their physical constitution and ovarian function, and can reduce their recurrence of ovarian endometriosis.
