The Feasibility of Hysteroscopic Endomyometrium Resection combined with concomitant Insertion of LNG-IUD for Treatment of Symptomatic Adenomyosis; A 36 Case Series with 5-year follow up result.

Background: Treatment for patients with symptomatic adenomyosis has been mainly by hysterectomy. The aim of this 5-year observational study was to assess the feasibility of Hysteroscopic Endomyometrium Resection with concomitant Insertion of LNG-IUD for symptomatic adenomyosis. Methods: From May 2015 and December 2022, a group of 36 women with symptomatic adenomyosis underwent this combined modality treatment at a community hospital. The core outcomes of the study were effective rate of dysmenorrhea, menorrhagia, secondary outcomes as hysterectomy, IUD expulsion, or premature removal, repeated the procedures. Results: The study followed the progress of 36 women, aged 42.9±4, over a period of five years. The procedures were performed safely, and no complications were observed. The total successful rate of amenorrhea was 27 of 36 (75%). For the Pain Control, the intervention led to a significant reduction in pain scores, with the mean pain score decreasing by approximately 63.4% (95% CI: -64.3% to -62.5%). For the Blood Loss, with the mean blood loss decreasing by approximately 75.77% (95% CI: 32.93% to 118.61%). The study also showed reduced CA-125 level, reduction in uterine length and volume, about 70% of patients reported being very satisfied and satisfied of this combined treatment. Conclusion: We demonstrated this combined modality is feasible and safe for treatment of symptomatic adenomyosis.
