Anorectal manometry to diagnose dyssynergic defecation: Systematic review and meta‐analysis of diagnostic test accuracy

Chronic constipation is a common condition, and dyssynergic defecation underlies up to 40% of cases. Anorectal manometry is recommended to assess for dyssynergic defecation among chronically constipated patients but remains poorly standardized. We aimed to evaluate the diagnostic accuracy of anorectal manometry and determine optimal testing parameters.We performed a systematic review with meta-analysis of diagnostic test accuracy including...
