title: Postpartum perineal morbidity after fourth-degree perineal repair.
abstract: OBJECTIVE
  We attempted to determine the frequency of postpartum perineal morbidity (dehiscence, infection, and rectovaginal fistula) in women after fourth-degree perineal repair.
  
  
  METHODS
  The medical records of 390 women at Parkland Memorial Hospital with fourth-degree perineal repair during 1989 and 1990 were retrospectively reviewed in a case-cohort study. Statistical analysis included chi 2 contingency tables, Fisher exact test, Mann-Whitney test, and analysis of variance.
  
  
  RESULTS
  Twenty-one of 390 women (5.4%) had postpartum perineal morbidity. Seven (1.8%) had dehiscence alone, 11 (2.8%) had infection and dehiscence, and 3 (0.8%) had infection alone. Overall there were 18 dehiscences (4.6%) and 14 infections (3.6%) in the total group with perineal morbidity. Two high rectovaginal fistulas were concomitantly detected in women with perineal dehiscence. Only shoulder dystocia, metritis, and postpartum fever occurred significantly more frequently in patients with postpartum perineal morbidity than in women without perineal morbidity. Smoking and human papillomavirus infection were not associated with perineal repair morbidity.
  
  
  CONCLUSIONS
  Postpartum perineal morbidity after fourth-degree perineal repair is an uncommon event. It is not predicted by readily preventable antepartum or intrapartum factors.
