Objective:To compare the efficacy and safety of Dienogest(DNG)with other drugs in non-surgi-cal pharmacologic treatment and long-term management of drugs after conservative surgery for endometriosis(EMT).Methods:We searched PubMed,Embase,Medline,Google Scholar,Cochrane Library,China National Knowledge Infrastructure,Wanfang,and Weipu databases from the establishment of the database until December 31,2023 for relevant literature on EMT pharmacotherapy.Meta-analysis was performed using Stata 18.0 software to assess the efficacy of DNG,gonadotropin-releasing hormone agonist(GnRH-a),compound short-acting oral contraceptive(COC)and levonorgestrel intrauterine sustained-release system(LNG-IUS)in reducing the diameter of ovarian endometrioma(OMA),relieving pelvic pain and preventing EMT postoperative recurrence in EMT pa-tients after non-surgical drug treatment and conservative surgery,as well as the adverse reactions of drugs.Re-sults:①During non-surgical medication treatment of EMT,there was no statistically significant difference(P＞0.05)between DNG and GnRH-a in reducing OMA diameter and relieving pelvic pain.Compared with COC,DNG was superior to COC in reducing the diameter of OMA(WMD 10.44 mm,P=0.017)and relieving pelvic pain(WMD 12.20 mm,P＜0.001).②During long-term medication management after conservative EMT surger-y:there was no statistically significant difference(P＞0.05)between DNG,GnRH-a,COC and LNG-IUS in re-ducing postoperative recurrence and controlling pelvic pain significant(P＞0.05).③Adverse drug reactions:com-pared with GnRH-a,DNG had a reduced risk of bone loss(bone density WMD2.78 g/cm3,P=0.038),hot fla-shes(OR 0.07,P＜0.001),and an increased risk of irregular vaginal bleeding(OR 19.10,P＜0.001);com-pared with COC,the risk of weight gain,mood abnormalities,and breast tenderness,nausea and vomiting,and sleep disorders in DNG were reduced(OR＜1,P＜0.05);compared with LNG-IUS,the risk of abnormalities of mood in DNG was increased(OR 9.87,P=0.033).Conclusions:DNG treatment is more effective than COC in non-surgical drug therapy for EMT.When supplemental medication was given after conservative EMT surgery,DNG,like other drugs,can effectively prevent postoperative recurrence and control pelvic pain.The safety of DNG is superior to GnRH-a and COC,slightly inferior to LNG-IUS.

Objective:To observe the effects and safety of dienogest on the volume and symptoms of ovarian endometrioma (OMA).Methods:The clinical data of 75 patients with OMA who underwent treatment with dienogest (2 mg/day) at the First Affiliated Hospital of Nanjing Medical University from July 1st 2020 to March 31st 2024 were retrospectively analysed, mainly comparing the changes in the volume of OMA and the visual analogue scale (VAS) scores of endometriosis-related pain before and after the treatment, as well as observing the changes in the blood biological indicators, liver and kidney function, coagulation function and changes in breast.Results:The median cyst volumes of the OMA patients at 3, 6 and 12 months of dienogest treatment were 13.21 cm 3 (volume reduction rate: 36.00%), 8.33 cm 3 (volume reduction rate: 56.00%) and 4.10 cm 3 (volume reduction rate: 77.62%), respectively, which were all significantly decreased from the pre-treatment period (all P<0.05). The VAS scores of pain of the OMA patients at 3, 6 and 12 months of dienogest treatment all were 0 mm. Blood cancer antigen 125 (CA 125) and cancer antigen 19-9 (CA 19-9) levels decreased progressively during treatment (all P<0.05). There were no statistical differences in the coagulation indexes, liver and kidney function indexes of the patients during dienogest treatment compared with those before treatment (all P>0.05). During the follow-up period, there were a few patients with changes in the growth sites or lesion category of the breast nodules, but there were no occurrence of breast cancer or precancerous lesions. Conclusion:Dienogest is effective in reducing OMA volume and alleviating endometriosis-related pain with few adverse effects.
