Comparison of vaginoscopic hysteroscopy and traditional hysteroscopy: A systematic review and meta-analysis

Outpatient hysteroscopy is a safe, feasible, and optimum procedure for the diagnosis and management of intrauterine pathologies.

To determine the best approach of outpatient hysteroscopy (vaginoscopic vs traditional) in terms of pain, duration of procedure, feasibility, safety, and acceptability.

PubMed, Embase, Google Scholar, and Scopus were searched from January 2000 to October 2021. No filters or restrictions were applied.

Randomized controlled trials comparing vaginoscopic hysteroscopy with traditional hysteroscopy in an outpatient setting.

Two authors independently performed a comprehensive literature search and collected and extracted data. The summary effect estimate was determined using both fixed effects and random-effects models.

Seven studies with 2723 patients (vaginoscopic [n = 1378] and traditional hysteroscopy [n = 1345]) were included. Vaginoscopic hysteroscopy was associated with a significant reduction in intraprocedural pain (standardized mean difference, -0.05 [95% confidence interval (CI), -0.33 to -0.23], I²  = 0%), procedural time (standardized mean difference, -0.45 [95% CI, -0.76 to -0.14], I²  = 82%), and fewer side effects (relative risk, 0.37 [95% CI, 0.15-0.91], I²  = 0%). The procedure failure rate was similar in both approaches (relative risk, 0.97 [95% CI, 0.71-1.32], I²  = 43%). Complications were mostly documented with traditional hysteroscopy.

Vaginoscopic hysteroscopy reduces the pain and duration compared with traditional hysteroscopy.
