Abstract
A case of ruptured ectopic pregnancy with a nondiagnostic culdocentesis is presented. Diagnosis was made by using open diagnostic peritoneal lavage. The patient underwent laparotomy, left salpingectomy, and cornual resection, and had no postoperative complications. In selected patients with suspected ectopic pregnancy, peritoneal lavage may serve as a helpful diagnostic procedure. © 1982 American College of Emergency Physicians.
