title: [Scarred uterus: is routine exploration of the cesarean scar after vaginal birth always necessary?].
abstract: OBJECTIVE
  To determine the risks and benefits of routine transcervical revision of previous cesarean uterine scar in patients with successful vaginal delivery.
  
  
  METHODS
  Retrospective study, over a 10-year period, of a routine palpation practice in the two units of our Obstetric department. Then, a 30-month prospective study comparing, in each unit, two different attitudes toward uterine revision (routine exploration vs symptomatic patients exploration) was conducted.
  
  
  RESULTS
  The retrospective part of our study led us to report 3 uterine ruptures (0.43% of all scarred uterus) and 14 dehiscences (2%) during the ten years. All uterine ruptures were sufficiently symptomatic in order to be suspected prior to scar exploration. No dehiscence needed surgical treatment. Some patients with bloodless dehiscence and no repair had subsequent vaginal deliveries with no scar separation found on uterine exploration. In the prospective part of our study, we found a significative difference in the occurrence of fever (18.9% vs 9.9%; p < 0.05) and antibiotic treatment (22.8% vs 12.7%; p < 0.05) between the two groups based on attitude toward uterine revision.
  
  
  CONCLUSIONS
  These data suggest that transcervical revision of previous cesarean uterine scar should be performed only in symptomatic patients (persistent suprapubic pain, placental retention, excessive bleeding during labor or delivery) or when risk factors are present (prolonged labor, prolonged expulsive efforts, instrumental extraction).
