Implication

Prospective cohort study reveals a 20 percent rate of anal sphincter injuries following vaginal delivery in primiparous women, highlighting the need for postpartum screening.

Key Points

To evaluate anal sphincter morphology, neuromuscular function, and bowel symptoms before and after childbirth in first-time mothers.
Prospective study of 38 primiparous women (mean age 31 years) evaluated during pregnancy and postpartum in the United States.
Diagnostic assessments included endoanal ultrasonography, anal manometry, pudendal nerve terminal motor latency measurements, and standardized bowel function questionnaires, with 3 patients undergoing cesarean delivery.
Clinical sphincter tears requiring primary repair occurred in 15% of patients, and postpartum endoanal ultrasound revealed external anal sphincter disruptions in 6 patients and scarring in 1 patient.
Among the 7 patients with ultrasound abnormalities, left pudendal nerve latency increased significantly postpartum (P < 0.05) and manometric pressures declined, whereas all 3 cesarean section patients had completely normal findings.
