Status and related factors of postoperative recurrence of ovarian endometriosis: a cross-sectional study of 874 cases.

PURPOSE: Exploring the status and related factors of postoperative recurrence of ovarian endometriosis. METHODS: This study analyzed the results of questionnaires conducted in 27 hospitals across the country from January 2019 to November 2021. All women were divided into recurrence group and non-recurrence group to analyze the recurrence rate and related factors after ovarian endometriosis surgery. RESULTS: The recurrence rates of ovarian endometriosis within 1 year, 1-2 years, 2-3 years, 3-4 years, 4-5 years and more than 5 years were 6.27%, 35.85%, 55.38%, 65.00% and 56.82%, respectively. Significant differences were found between two groups in terms of age at surgery (OR: 0.342, 95%CI: 0.244-0.481, P < 0.001), presence of dysmenorrhea (OR: 1.758, 95%CI: 1.337-2.312, P < 0.001), presence of adenomyosis (OR: 1.948, 95%CI: 1.417-2.678, P < 0.001) and family history of endometriosis or adenomyosis (OR: 1.678, 95%CI: 1.035-2.721, P = 0.021). The age at surgery (OR: 0.358, 95%CI: 0.253-0.506, P < 0.001), presence of dysmenorrhea (OR: 1.379, 95%CI: 1.026-1.853, P = 0.033) and presence of adenomyosis (OR: 1.799, 95%CI: 1.275-2.537, P = 0.001) were significantly associated with endometrioma recurrence in multivariate analysis. No significant associations were found between the recurrence rate and body mass index (BMI), educational background, age of menarche, gravida, parity, uterine leiomyoma, endometrial polyps or postoperative use of gonadotropin-releasing hormone agonist (GnRH-a). CONCLUSIONS: Dysmenorrhea and presence of adenomyosis are independent risk factors for postoperative recurrence of ovarian endometriosis, and older age is an independent protective factor for postoperative recurrence.

Chinese medicine improves postoperative quality of life in endometriosis patients: a randomized controlled trial.

OBJECTIVE: To investigate the effect of Chinese medicine (CM) and Western medicine (WM) on quality of life (QOL) after conservative surgery for endometriosis. METHODS: A total of 320 patients with endometriosis were randomized into two groups by using random block design, CM group (160 cases, activating blood circulation and removing blood stasis treatment based on syndrome differentiation) and WM group (160 cases, gonadotropin-releasing hormone agonist or gestrinone treatment) after conservative surgery. Treatment was given for 3-6 months (according to the revised American Fertility Society scoring system stage), and the World Health Organization QOL-BREF (WHOQOL-BREF) was applied to patients before and after treatment to assess QOL. RESULTS: There were 136 cases in the CM group and 141 cases in the WM group completing therapy. In the CM group, the use of the WHOQOL-BREF showed that the physical, psychological and environmental scores posttreatment were significantly higher than those at pre-treatment (P < 0.05), and for 12 items (pain and discomfort, energy and fatigue, sleep and rest, mobility, activities of daily living, work capacity, negative feelings, health and social care: accessibility and quality, participation in and opportunities for recreation/leisure activities, appetite, QOL score, overall health status and QOL), the difference in scores was significant (P < 0.05). In the WM group, 4 items (pain and discomfort, opportunities for acquiring new information and skills, QOL score, overall health status and QOL) had significantly different scores post-treatment compared with those at pre-treatment (P < 0.05). Before treatment, the QOL in the two groups of patients showed no significant difference (P > 0.05). After treatment, the scores for physical health in the CM group were significantly higher than those of the WM group (P < 0.05) and the scores of 4 items (mobility, activities of daily living, sexual activity, QOL score) in the CM group were significantly higher than those in the WM group (P < 0.05). CONCLUSIONS: CM and WM treatment could improve the QOL of patients with endometriosis after conservative surgery. CM treatment is more effective than WM.
