title: Evaluation of surgery in simple ovarian cysts.
abstract: OBJECTIVE
  To evaluate the surgery in simple ovarian cysts.
  
  
  METHODS
  From Jan. 1994 to Dec. 1999, 221 women with simple ovarian cysts were admitted into our hospital. The diameter of cysts was < 5 cm in 76 cases, and was > or = 5 cm in 145 cases ultrasonically. One hundred and eighty-four patients underwent laparoscopy, and thirty-seven underwent laparotomy.
  
  
  RESULTS
  Histological findings showed no malignancy in this series. Simple cysts, paraovarian cysts and corpus luteum were found histologically in 90.8% of cases with cysts < 5 cm, and 60% of those with cysts > 7 cm respectively, their difference was significant (chi2=37.13, P<0.001). The simple cysts, paraovarian cysts and corpus luteum cysts were found in 81.5% of postmenopausal women and 84.0% of premenopausal women.
  
  
  CONCLUSIONS
  Patients with cysts > 7 cm are indicated for surgical procedures, while a period of followup is acceptable for patients with cysts < 7 cm, and surgery is advisable if the cyst is persistent during followup. Postmenopausal women with cysts should have operations.
