Complete list of historical versions of study NCT01320995 on Archive Site
  • Wexner anal incontinence score [ Time Frame: 3 months ]
  • Visual Analog Scale for discomfort during perineal ultrasound [ Time Frame: 2 hours ]
    Ranges from 0.0 to 10.0
  • Kappa coefficient for second reading of ultrasounds [ Time Frame: 30 days ]
    A second reading of each ultrasound is obtained within 30 days. The Kappa coefficient of concordance will be calculated between the two readings.
  • Presence/absence of a sphincter tear [ Time Frame: 2 hours ]
    Presence/absence of a sphincter tear immediately after delivery.
  • Patient requires anal sutures (yes/no) [ Time Frame: 2 hours ]
    Patient requires anal sutures after delivery?
  • Presence/absence of suture infection [ Time Frame: 3 months ]
    Has an infection ocurred between delivery and the follow up visit at 3 months post partum?
  • Questionnaire PFIQ [ Time Frame: 3 months ]
  • Questionnaire PFDI [ Time Frame: 3 months ]
  • Questionnaire SF36 [ Time Frame: 3 months ]

Perineal Echography in the Delivery Room for the Detection of Anal Lesions
Perineal Echography in the Delivery Room for the Detection of Anal Lesions Among Primiparous Mothers: a Randomized Study
The main objective of this study is to compare the rate of anal incontinence (measured by the Wexner score, qualitative and quantitative (> 4)) at 3 months post partum among primiparas with vaginal tears ≥ 2nd degree who receive a sphincter injury screening at delivery by conducting a sphincter ultrasound in the delivery room versus a similar group of women who do not benefit from screening.

Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Diagnostic
Procedure: Perineal ultrasound
Perineal ultrasound is performed after delivery in order to better detect sphincter lesions.
  • Experimental: Experimental arm
    In this arm, perineal ultrasound is used directly after delivery in order to hypothetically better detect anal lesions.
    Intervention: Procedure: Perineal ultrasound
  • No Intervention: Standard arm
    No perineal ultrasound immediately after delivery.
