Study Description
Brief Summary:
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.

Condition or disease Intervention/treatment
Parturition Procedure: Perineal ultrasound

Arms and Interventions

Arm Intervention/treatment
Experimental: Experimental arm
In this arm, perineal ultrasound is used directly after delivery in order to hypothetically better detect anal lesions.
Procedure: Perineal ultrasound
Perineal ultrasound is performed after delivery in order to better detect sphincter lesions.
No Intervention: Standard arm
No perineal ultrasound immediately after delivery.

Outcome Measures

Primary Outcome Measures :
  1. Presence/absence of anal incontinence [ Time Frame: 3 months ]
    Anal incontinence is defined as a Wexner score > 4

Secondary Outcome Measures :
  1. Wexner anal incontinence score [ Time Frame: 3 months ]
  2. Visual Analog Scale for discomfort during perineal ultrasound [ Time Frame: 2 hours ]
    Ranges from 0.0 to 10.0

  3. 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.

  4. Presence/absence of a sphincter tear [ Time Frame: 2 hours ]
    Presence/absence of a sphincter tear immediately after delivery.

  5. Patient requires anal sutures (yes/no) [ Time Frame: 2 hours ]
    Patient requires anal sutures after delivery?

  6. 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?

  7. Questionnaire PFIQ [ Time Frame: 3 months ]
  8. Questionnaire PFDI [ Time Frame: 3 months ]
  9. Questionnaire SF36 [ Time Frame: 3 months ]
  10. Questionnaire Euroqol [ Time Frame: 3 months ]
