BACKGROUND: Adenomyosis is a gynaecological lesion that impairs female fertility and contributes to reduced quality of life. There are several surgical and medical options for the management of this lesion; however, women who wish to conceive opt for medical therapies such as the levonorgestrel intrauterine device (LNG-IUS) and dienogest, which have various outcomes. To date, there is no consensus regarding which is more effective.
OBJECTIVE: To compare the effectiveness of LNG-IUS and dienogest for the management of adenomyosis, and explore the risk of occurrence of known side effects for both treatments.
METHODS: Systematic review and meta-analysis exploring the effectiveness of LNG-IUS and dienogest for the management of adenomyosis.
METHODS: A literature search was conducted using PICO guidelines and EMBASE, PubMed/MEDLINE, Scopus and Web of Science databases. Only clinical trials were collected and analysed.
RESULTS: Of the 792 studies that were initially identified, six were eligible for inclusion in this study. The studies included a total of 707 women; of these, 270 were treated with LNG-IUS, 354 were treated with dienogest, and 83 were controls. All the studies were from Asia (Bangladesh n = 1, China n = 2, India n = 1, Japan n = 1, South Korea n = 1). Dienogest was found to reduce pelvic pain significantly, evidenced by a lower visual analogue scale score, compared with LNG-IUS. Also, dienogest led to a significant reduction in uterine volume compared with LNG-IUS. However, subjects in the LNG-IUS group had significantly higher levels of haemoglobin than those in the dienogest group. Nonetheless, the occurrence of side effects such as weight gain, breast tenderness/distension, headache, insomnia/sleep disorder, depression/mood disorder, skin disorder/acne, and coital discomfort/reduced libido were comparable in both treatment groups.
CONCLUSIONS: Dienogest may be more effective than LNG-IUS for the management of adenomyosis, as it shows a superior effect in the reduction of pelvic pain and uterine volume. As only six studies were included in the present meta-analysis due to the paucity of data in the literature, it is recommended that well-designed randomized controlled trials comparing the effectiveness of dienogest with LNG-IUS should be conducted.

OBJECTIVE: To summarize evidence on levonorgestrel releasing intrauterine system (LNG-IUS) in the treatment of adenomyosis (AM) and to identify potential research gaps.
METHODS: Search was conducted in MEDLINE, The Cochrane Library, EMBASE, CBM, CNKI, and Wanfang. We included studies investigating patients with AM treated with LNG-IUS combined with conservative therapy.
RESULTS: Thirty-nine studies compared LNG-IUS with other conservative therapeutic drugs. The most common comparison was GnRH-a + LNG-IUS vs. LNG-IUS alone, followed by LNG-IUS vs. mifepristone, expected treatment, and GnRH-a. GnRH-a + LNG-IUS was more beneficial in reducing the intensity of dysmenorrhea than LNG-IUS alone at the 6-month follow-up in patients with an enlarged uterus and moderate to severe dysmenorrhea. Large and well-designed studies are needed to confirm the efficacy of LNG-IUS and GnRH-a on reducing uterine volume at 6-month follow-up. Thirty-two studies investigated LNG-IUS as the postoperative management. The most common comparison was surgical excision + LNG-IUS vs. surgical excision. Results showed VAS scores were lower in the surgical excision + LNG-IUS group than in the surgical excision group at the 1-year follow-up. Evidence on endometrial thickness, quality of life, adverse events and beneficial effect at 3 and 5 years are needed.
CONCLUSIONS: Combined GnRH-a and LNG-IUS treatment was more efficacious than LNG-IUS alone for patients with an enlarged uterus and moderate to severe dysmenorrhea. Moreover, LNG-IUS seemed to show potential long-term benefits in postoperative therapy, warranting further meta-analysis for confirmation.

OBJECTIVE: Use of 52-mg levonorgestrel intrauterine system (LNG-IUS) in adolescents for heavy menstrual bleeding (HMB), dysmenorrhea, and contraception has increased, yet little is known about the factors predicting removal and dissatisfaction in adolescents. The aim of this study was to identify factors predicting LNG-IUS removal in adolescents.
METHODS: This was a retrospective cohort study including all adolescents (9-19 years) who underwent LNG-IUS insertion between 2012 and 2021 (n = 536). A medical record review was conducted and data were collated on medical and gynecological history, age, indications for insertion, complications, expulsions, and removals. The data were analyzed using χ2 tests.
RESULTS: Indications for LNG-IUS insertions (n = 536) among 517 individual patients (n = 517) included menstrual management (n = 142), HMB alone (n = 118), HMB and pelvic pain/dysmenorrhea (n = 105), dysmenorrhea/pelvic pain alone (n = 47), and contraception (n = 16). Associated diagnoses included intellectual disability (44.29%, 229/517), chronic pain conditions (12.77%, 66/517), and additional mental health concerns (24.37%, 126/517). Patient dissatisfaction with LNG-IUS led to removal in 61 (11.38%), mostly for pain or persistent bleeding. Higher removal rates occurred in those with associated chronic pain conditions (46.97%, χ2 = 55.9, P < .05), mental health concerns (16.67%, χ2 = 5.06, P < .05), and bleeding disorders (26.32%, χ2 = 5.09, P < .05). Among the cohort with an intellectual disability, lower rates of removal occurred (5.7%, χ2 = 11.2, P < .05). Whereas the LNG-IUS removal rate among gender-diverse youth was 23.07%, this was not statistically significant. Younger age was also not associated with a statistically significant increase in removals (13.72%, χ2 = 0.73, P > .05).
CONCLUSIONS: Adolescents have a low dissatisfaction and removal rate (11.38%) of LNG-IUS. Chronic pain, bleeding tendency, and mental health concerns are associated with higher removal rates and intellectual disability with lower rates. These findings are useful in counselling patients and families about LNG-IUS.

To evaluate the feasibility and effectiveness of hysteroscopic suture fixation of the levonorgestrel-releasing intrauterine system (LNG-IUS) for the treatment of adenomyosis.
A retrospective case series.
Two teaching hospitals with the technology of hysteroscopic suture fixation of the LNG-IUS.
The study reviewed 79 adenomyosis patients who received the hysteroscopic suture fixation of the LNG-IUS from January 2021 to May 2022.
Hysteroscopic suture fixation of the LNG-IUS to the posterior uterine wall with nondissolvable suture.
All patients underwent one-year postoperative follow-up to evaluate the LNG-IUS expulsion rate, postoperative efficacy, and side effects. Two patients (2.6%) experienced expulsion of the LNG-IUS at 8 months and 12 months postoperatively, respectively. The visual analog pain scale, pictorial blood loss assessment chart score and carbohydrate antigen 125 markedly decreased after the suture fixation of the LNG-IUS compared with baseline in all patients (p <.001). Hemoglobin increased significantly (p <.001). The most common side effect was irregular bleeding, which accounted for 44.3%. The second common side effect was weight gain, which accounted for 29.2%. The composite effectiveness based on pain and bleeding showed that the effective treatment rates at 1, 3, 6, and 12 months after surgery were 92.4%, 97.4%, 96.2%, and 97.4% respectively.
Hysteroscopic suture fixation of the LNG-IUS to the uterine fundus was associated with low expulsion rates and significantly improved dysmenorrhea and bleeding.

Background This study aimed to examine the role of a levonorgestrel intrauterine system (LNG-IUS) in the treatment of heavy menstrual bleeding (HMB) regarding improvements in bleeding patterns and quality of life (QOL) and determine the reason for its failure or withdrawal from treatment in some patients. Methodology This retrospective study was conducted in a tertiary care center in eastern India. A seven-year assessment, with both qualitative and quantitative assessments, of the effect of LNG-IUS in women with HMB was performed using the Menorrhagia Multiattribute Scale (MMAS) and Medical Outcomes Study 36-Item Short-Form Health Survey (MOS SF-36) score as a tool to assess the QOL, and the pictorial bleeding assessment chart (PBAC) to assess bleeding patterns. The study population was divided into the following four groups based on duration: three months to one year, one to two years, two to three years, and more than years. The continuation, expulsion, and hysterectomy rates were evaluated. Results The mean MMAS and MOS SF-36 scores increased significantly (p < 0.05) from 36.73 ± 20.40 to 93.72 ± 14.62 and 35.33 ± 6.73 to 90.54 ± 15.89, respectively. The mean PBAC score decreased from 176.36 ± 79.85 to 32.19 ± 63.87. In total, 348 women (94.25%) continued the LNG-IUS, and 3.44% had uncontrolled menorrhagia. Furthermore, at the end of seven years, the expulsion rate was 2.28% due to adenomyosis and pelvic inflammatory disease, and the hysterectomy rate was 5.75%. In addition, 45.97% and 48.27% of the participants had amenorrhea and hypomenorrhea, respectively. Conclusions LNG-IUS improves bleeding and QOL in women with HMB. In addition, it requires less skill and is a non-invasive and nonsurgical option, which should be considered first.

Background This study aims to evaluate the effect of operative hysteroscopy and levonorgestrel-releasing intrauterine system (LNG-IUS) insertion for abnormal uterine bleeding on sexual function and, if it improves sexual function, to examine differences in sexual function between women undergoing hysteroscopy and women using LNG-IUS. Methods Ninety women aged between 25 and 52 enrolled in the study. Participants were divided into two groups, including 45 operative hysteroscopy patients and 45 LNG-IUS patients. All patients completed the Female Sexual Function Index (FSFI) questionnaire pre-treatment and after three months post-treatment. Pre- and post-treatment FSFI scores were compared both within and between groups. Results The mean FSFI scores at three months following both treatments were significantly higher than baseline in both groups (p<0.05). When the two groups were compared, no significant difference was observed between baseline and three-month post-treatment differences in FSFI scores except for the pain domain. In the pain domain of the FSFI questionnaire, a more significant improvement was found in the LNG - IUS inserted group compared to the operative hysteroscopy group. Conclusion Patients had improvement in sexual functions after both operative hysteroscopy and LNG - IUS insertion treatment. No significant difference was observed in hysteroscopy and LNG-IUS patients after both treatments in terms of sexual function according to scores calculated by FSFI, except for the pain domain. Significant improvement was observed in the pain domain of the FSFI for the LNG - IUS inserted group compared to the operative hysteroscopy group, thus demonstrating a significant effect and improvement for dyspareunia and chronic pelvic pain complaint in the LNG-IUS inserted group.

Twenty-five percent of cases of endometrial cancer appear in women with unfulfilled reproductive desires. An adequate selection of patients and a close hysteroscopic follow-up to monitor the endometrial response to the levonorgestrel-releasing intrauterine system (LNG-IUS) may be a valid and safe option for these patients. This is a case series and review of the literature study. We included eight patients diagnosed of complex endometrial hyperplasia with atypia (CEHA) or stage 1AG1 well-differentiated endometrial cancer without myometrial invasion who desired to get pregnant and opted for a conservative treatment. Follow-up was performed with hysteroscopy and directed biopsy at 3, 6 and 12 months. Of the 854 cases of complex endometrial hyperplasia with atypia (CEHA)/endometrial cancer were diagnosed, 2.3% were candidates for conservative management. We obtained a favourable regression of 71.2% at 6 months and 57% at one year with hormonal treatment. Conservative treatment in complex endometrial hyperplasia with atypia (CEHA)/low-grade endometrial cancer in reproductive age patients with a strong desire for pregnancy is feasible.

To compare the treatment efficacies of high-intensity focused ultrasound (HIFU), HIFU combined with gonadotrophin-releasing hormone agonist (GnRH-a), and HIFU combined with GnRH-a and levonorgestrel-releasing intrauterine system (LNG-IUS) for adenomyosis. We conducted a literature search in SCIENCE DIRECT, COCHRANE LIBRARY, WILLEY ONLINE LIBRARY, PUBMED, and TAYLOR FRANCIS. A total of 471 articles identified, 12 were included in a systematic review, and 11 of them deemed quantitively eligible included in the meta-analysis. The efficacies of the three treatment regimens were assessed using the dysmenorrhea and menstrual scores at 3, 6, 12, 24 months. Of the three regimens, HIFU combined with GnRH-a and LNG-IUS provides the best outcome. On dysmenorrhea score at 6 months there was significantly different higher heterogeneity with P < 0.00001 (I2 = 100% WMD 21.44 [6.34, 36.53]) with statistical significance P = 0.005. At 12 months there was significantly different higher heterogeneity P < 0.00001 (I2 = 100% WMD 23.47 [6.00, 40.94]) with statistically significant P < 0.008. At 24 months there was significantly different higher heterogeneity P < 0.0005 (I2 = 92% WMD 6.05 [4.81, 7.30]) with statistical significance P < 0.00001. HIFU combined with GnRH-a and LNG-IUS on menstrual score at 3 months was significantly different higher heterogeneity with P < 0.00001 (I2 = 100% WMD 56.23 [16.01, 96.45]) with statistical significance P = 0.006. At 6 months there was significantly different higher heterogeneity P < 0.00001 (I2 = 99% WMD 93.86 [64.15, 123.57]) with statistical significance P < 0.00001. At 12 months there was significantly different higher heterogeneity P < 0.00001 (I2 = 99% WMD 97.13 [67.81, 126.46]) with statistical significance P < 0.00001 compared to treatments with only HIFU and HIFU combined with GnRH-a. HIFU combined with GnRH-a and LNG-IUS treatment is more effective than only HIFU monotherapy and HIFU combined with GnRH-a.

UNASSIGNED: To compare efficacy and safety of the levonorgestrel-releasing intrauterine system (LNG-IUS) with medical treatments for women with heavy menstrual bleeding.
UNASSIGNED: We searched PubMed, Embase, the Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure (CNKI), and Wanfang databases for relevant randomized controlled trials (RCTs) in November 2021. All meta-analyses were performed using the random-effects model. PROSPERO registration number: CRD42021295379.
UNASSIGNED: A total of trials (with 14 references) reporting on 1,677 women were included in this systematic review. The majority of the included RCTs were rated with low-to-unclear risk of bias in selection, detection, attrition, reporting, and other bias. All RCTs were rated as high risk in performance bias because blinding was difficult to ensure in the compared groups. Results of meta-analyses revealed that the number of clinical responders was greater in the LNG-IUS group than that in the medical treatments group at both 6-month (steroidal: five RCTs; n = 490; risk ratio [RR]: 1.72 [1.13, 2.62]; I 2 = 92%; nonsteroidal: one RCT; n = 42; RR: 2.34 [1.31, 4.19]) and 12-month (steroidal: three RCTs; n = 261; RR: 1.31 [1.01, 1.71]; I 2 = 74%) endpoints, with no clear differences on number of dropouts, and the incidence of adverse events.
UNASSIGNED: Evidence indicates that LNG-IUS is superior to the medical treatments in short-term and medium-term clinical responses, blood loss control, compliance, and satisfaction. Meanwhile, frequency of adverse events related to LNG-IUS is acceptable.

To evaluate the efficacy and safety of high-intensity focused ultrasound (HIFU) combined with the levonorgestrel intrauterine system (LNG-IUS) for adenomyosis.
We searched PubMed, Embase, Cochrane Library, Web of Science, CNKI, SinoMed, Wanfang, and VIP databases from their inception to Nov 20, 2021 for relevant articles that compared HIFU combined with LNG-IUS vs. HIFU alone in patients with adenomyosis. RevMan5.4 software was used for the data analysis. The primary outcome was changes in volume of the uterine. Secondary outcomes included visual analog scale (VAS) scores for dysmenorrhea, serum CA125 level, recurrence rate, changes in volume of the adenomyotic lesion, menstrual volume scores, and adverse reactions. Data synthesis was conducted using a random-effects model with significant heterogeneity (I2 > 50%), and using a fixed-effects model otherwise. This study is registered on the PROSPERO platform (CRD42021295214).
The final analysis included 13 studies, with a total of 1861 patients. Results of analysis revealed that there was no significant difference in uterine volume reduction between the HIFU control group and the HIFU/LNG-IUS group at 3 months after procedure (MD:30.63). Compared with the HIFU control group, the HIFU/LNG-IUS group had more pronounced reduction in uterine volume at 6 (MD:29.04) and 12 months (MD:22.10) after procedure. The HIFU/LNG-IUS group has lower VAS scores for dysmenorrhea than the HIFU control group at 3 (MD:1.68), 6 (MD:1.69), and 12 months (MD:1.30) after procedure. Serum CA125 level in the HIFU/LNG-IUS group decreased more significantly than the HIFU control group at 6 (MD:18.34) and 12 months (MD:18.49) after procedure. The recurrence rate in the HIFU/LNG-IUS group was lower than that in the HIFU control group (RR:0.20).
Compared to HIFU control group, HIFU/LNG-IUS group for the management of adenomyosis had more advantages in alleviating symptoms and decreasing the volumes of the uterine and adenomyotic lesions. However, since the number of the included studies was too small and some of them were not RCT, this conclusion needs to be referenced with caution.
