Review Meta AnalysisA systematic review and meta-analysis of randomized studies comparing misoprostol versus placebo for cervical ripening prior to hysteroscopy.
Hysteroscopy is an effective method for examining the uterine cavity but has some limitations, including the occasional need for cervical dilatation. Misoprostol is routinely used for cervical dilatation in various procedures but has not gained wide acceptance for use before hysteroscopy. ⋯ There is insufficient evidence to recommend the routine use of misoprostol before every hysteroscopy. As the lack of serious benefit from misoprostol is unlikely to be due to type II error, its use should be reserved for selected cases.
