title: Role of previous ectopic pregnancy in altering the presentation of suspected ectopic pregnancy.
abstract: OBJECTIVE
  To evaluate the differences in the presentations of women with and without a prior history of an ectopic pregnancy and a suspicion of a current ectopic.
  
  
  METHODS
  Evaluation of a cohort of patients presenting to an emergency department to exclude an ectopic pregnancy. Over a 58-month study period (January 1992-October 1996), 1,510 consecutive, pregnant women presenting to an emergency department with pelvic pain and/or vaginal bleeding to exclude an ectopic pregnancy were evaluated. A comparison was made of the presenting signs and symptoms between patients with and without a previous history of an ectopic pregnancy.
  
  
  RESULTS
  Of patients presenting to exclude an ectopic pregnancy, 105 had a history of an ectopic pregnancy, and 1,355 had no such history. Fifty patients were excluded because they were lost to follow-up or transferred their care to another hospital. Those with a history of an ectopic pregnancy were more likely to be diagnosed again with an ectopic pregnancy, were older and were more likely to have a history of pelvic inflammatory disease and abdominal surgery. Patients with a history of an ectopic pregnancy presented earlier with a lower hCG level.
  
  
  CONCLUSIONS
  Women with a previous history of an ectopic present in a clinically different manner than do those without such a history.
