title: Expectant management versus elective curettage for the treatment of spontaneous abortion.
abstract: OBJECTIVE
  To determine whether the amount of intrauterine tissue was prognostic of the risk of complications associated with the management of nonviable pregnancies diagnosed in the first trimester before cervical dilatation (termed here impending abortion) with either expectant observation or elective curettage.
  
  
  METHODS
  Historic cohort study.
  
  
  METHODS
  University Infertility Service.
  
  
  METHODS
  All women with nonviable pregnancies followed by the Division of Reproductive Endocrinology during a 5-year period. The patients were divided into those with significant intrauterine tissue (gestational sac > 10 mm) and those with minimal intrauterine tissue.
  
  
  METHODS
  Women either underwent elective curettage or were followed expectantly.
  
  
  METHODS
  Complication rates.
  
  
  RESULTS
  In 89 women with minimal tissue, no complications occurred regardless of treatment mode. In 63 women with significant intrauterine tissue, expectant management resulted in more complications (9/24) than elective curettage (1/39). In the expectant group, complications included missed abortion, septic abortion, and incomplete abortion requiring emergency curettage, with one patient requiring a transfusion. In the curettage group one uterine perforation occurred.
  
  
  CONCLUSIONS
  In women with impending abortions and minimal intrauterine tissue, expectant treatment is safe after ectopic pregnancy has been excluded. In patients with significant intrauterine tissue, the risk of complications may be decreased by elective uterine curettage compared with expectant management.
