Efficacy, safety, and feasibility of the treatment of intrauterine pathologies with the mini-resectoscope: A systematic review

Background: Hysteroscopy represents the gold standard for the diagnosis and treatment of intrauterine pathologies. The advent of the mini-resectoscope heralded a new era in intrauterine surgery, both in inpatient and outpatient settings. Objectives: To evaluate the effectiveness, safety, and feasibility of the mini-resectoscope for the treatment of intrauterine pathologies. Search Strategy: Electronic databases were searched for English-language trials describing surgical procedures for uterine pathologies performed with a mini-resectoscope until 30 April 2023. Selection Criteria: Retrospective or prospective original studies reporting the treatment of uterine pathologies with mini-resectoscope were deemed eligible for the inclusion. Data Collection and Analysis: Data about study features, characteristics of included populations, surgical procedures, complications, and results/outcomes were collected. Results: Seven papers that met the inclusion criteria were included in this systematic review. Quantitative analysis was not possible due to data heterogeneity. A descriptive synthesis of the results was provided accordingly to the pathology hysteroscopically removed/corrected: polyps and myomas, uterine septum, intrauterine synechiae, and isthmocele. Conclusions: The mini-resectoscope is poised to play a leading role in hysteroscopic surgery for many pathologies, both in inpatient and outpatient settings. Since some applications of the mini-resectoscope have not yet been thoroughly investigated, future studies should address current knowledge gaps, designing high-quality comparative trials on specific applications.
