Objective: A meta-analysis was conducted to evaluate the overall pregnancy outcomes after uterus-sparing operative treatment in patients with adenomyosis (AD).
Data sources: We searched PubMed, Web of Science, Cochrane Library, and Embase for literature from January 2000 to January 2022.
Methods of study selection: We included all studies reporting reproductive outcomes of uterine-sparing surgery for patients with AD with fertility requirements. Surgical treatment was classified as complete excision or incomplete removal of AD and nonexcisional techniques for induction of necrosis in AD. The latter included physically removing the tissue where pathology is present or disrupting the blood flow to the affected area, involving high-intensity focused ultrasound, microwave ablation, radiofrequency ablation, and uterine artery embolization. Two independent researchers performed study selection according to the screening criteria.
Tabulation, integration, and results: A total of 13 studies with 1319 patients with AD were included in this study, comprising 795 women wishing fertility. Pooled estimates of pregnancy, miscarriage, and live-birth rates after excisional treatment for women attempting to conceive were 40% (95% confidence interval [CI], 29-52), 21% (95% CI, 16-27), and 70% (95% CI, 64-76), respectively, and corresponding rates after nonexcisional treatment were 51% (95% CI, 42-60), 22% (95% CI, 13-34), and 71% (95% CI, 57-83), respectively. The differences were not statistically significant.
Conclusion: Excisional treatment could be a treatment consideration for patients with symptomatic AD and infertility for several years or repeated failure of assisted reproductive technology. Nonexcisional techniques may be considered probably for AD-related infertility.
