Purpose. To assess the feasibility rate of one-step hysteroscopic myomectomy according to the technique adopted. Methods. In July 2016, PubMed, ClinicalTrials.gov, SCOPUS, Scielo, and AJOL databases were used for searching references. Series of in-patient hysteroscopic myomectomies reporting success rate in only one-step procedure, categorization of submucous fibroids, explanation of the surgical technique, and description of patients were considered eligible for meta-analysis (retrospective, prospective randomized studies). Two authors extracted the data. Rate of myomectomies accomplished in only a surgical step and rate of intraoperative complications were extracted per protocol. A modified GRADE score was used for quality assessment. Random-effect models were already assumed. Mean rates were compared among subgroups. Results. One thousand two hundred and fifty-seven studies were screened and 241 of these were read for eligibility. Seventy-eight series were included in qualitative synthesis and 24 series were included in quantitative synthesis. Wide heterogeneity was found. In series with <50% of G2 myomas treated, the slicing technique feasibility rate was 86.5% while techniques for enucleating the deep portion of the myomas showed a feasibility rate of 92.3% (p<0.001). In series with ≥50% of G2 myomas treated, the slicing technique feasibility rate was 70.6% while techniques for enucleating the deep portion of myomas showed a feasibility rate of 88.4% (p<0.001). Complications were significantly lower for alternative techniques to the classical slicing. Conclusion. In case of submucous myomas with intramural development, the slicing technique was correlated with a lower rate of in-patient hysteroscopic myomectomies accomplished in a one-step procedure and a higher complications rate.
