Abstract:
Objective:To explore the value of endorectal echodefecography（EDF）in the evaluation of functional anorectal disorders（FAD）.Methods:A total of 67 patients clinically diagnosed with FAD who underwent EDF at the Sixth Affiliated Hospital of Sun Yat-Sen University from September 2021 to August 2024 were retrospectively collected. EDF was performed using a combination of transrectal and transperineal scans. XRD was used as the reference standard.Results:The diagnostic accuracy，sensitivity，specificity，positive predictive value，and negative predictive value of EDF for common FADs were as follows：for rectocele，85.1%，84.6%，85.4%，78.6%，and 89.7%；for rectal intussusception，79.1%，50.0%，93.3%，78.6%，and 79.2%；for external rectal prolapse，94.0%，71.4%，100%，100%，and 93.0%；for anismus，82.1%，66.7%，82.8%，15.4%，and 98.1%；for perineal descent，65.7%，54.2%，72.1%，52.0%，and 52.0%.Conclusions:EDF is valuable for evaluating FAD，especially for external rectal prolapse and rectocele. It can serve as an effective complement to XRD and provide a non-invasive and safe imaging method for FAD diagnosis.
