title: Accuracy of the preoperative diagnosis in 100 emergency laparoscopies performed due to acute abdomen in nonpregnant women.
abstract: OBJECTIVE
  To assess the validity of preoperative diagnosis in the emergency room in relation to the surgical diagnosis at laparoscopy.
  
  
  METHODS
  Retrospective study (Canadian Task Force classification II-2).
  
  
  METHODS
  University-affiliated hospital.
  
  
  METHODS
  One hundred consecutive nonpregnant women who underwent emergency laparoscopy for acute abdomen between 1997 and 1999. Intervention. Emergency diagnostic laparoscopy.
  
  
  RESULTS
  The preoperative diagnosis was confirmed by laparoscopy in 29 (44%) of 66 cases of ovarian torsion, 9 (82%) of 11 cases of ovarian cyst, and 12 (80%) of 15 cases of bleeding corpus luteum. Unsuspected diagnoses among nonconfirmed cases were ovarian cysts (24), adhesions (5), bleeding corpus luteum (3), degenerative myomas (3), pelvic inflammatory disease (2), and appendicitis (1). The preoperative diagnosis was confirmed by emergency laparoscopy in 56% of all patients. Diagnoses most likely to be predicted accurately were ovarian cysts and bleeding corpora lutea. Ovarian torsion was most difficult to diagnose preoperatively, as it was not confirmed during laparoscopy in over half patients. Ovarian cysts and adhesions were the most common unsuspected findings.
  
  
  CONCLUSIONS
  Patients and surgeons alike should be aware of difficulty making accurate preoperative diagnoses of acute gynecologic pathologies in the emergency room. (J Am Assoc Gynecol Laparosc 8(1):92-94, 2001)
