To investigate the diagnostic accuracy and interobserver agreement among sonologists when assessing offline ultrasound (US) video sets of the "sliding sign" and among gynecologic surgeons when assessing corresponding laparoscopic video sets to predict pouch of Douglas (POD) obliteration and to compare the performance of the groups. ⋯ Interobserver agreement was superior among senior sonologists. Prediction of POD obliteration using offline US videos by senior sonologists is comparable to offline assessments of laparoscopic videos by advanced laparoscopists for prediction of POD obliteration.
