CJ25201Grading of obstetric anal sphincter injury: endoanal or transperineal ultrasound?
Childbirth injuries to the anal sphincter muscles affect up to 5% of women and can lead to devastating bowel control problems that severely impact quality of life. This study compared two ultrasound techniques for detecting these injuries after surgical repair, finding that the transperineal method (placing the probe externally on the skin) gave similar results to the gold-standard but more invasive endoanal ultrasound (requiring probe insertion). These findings suggest the less invasive external ultrasound could become a practical alternative.
