title: Use of the ultrasound surgical aspirator in ovarian cancer: a case-control study.
abstract: BACKGROUND
  This study was undertaken to evaluate the use of the ultrasound surgical aspirator in ovarian cancer and to determine if cytoreduction was improved with its use.
  
  
  METHODS
  The study is a retrospective case control trial. Twenty-six consecutive ovarian cancer patients who had the ultrasound surgical aspirator used during their surgery were retrospectively compared to 25 consecutive ovarian cancer patients who did not have the ultrasound surgical aspirator used during their surgeries. The latter group had their surgeries immediately before the ultrasound surgical aspirator was introduced into the hospital. Both groups were similar in age, stage, histology type, grade, and median number of chemotherapy cycles.
  
  
  RESULTS
  Patients that had the ultrasound surgical aspirator used had a 69% optimal cytoreduction rate compared to 16% in the control group (p = .001). This was statistically significant (p = 0.001). Survival time was equal in both groups.
  
  
  CONCLUSIONS
  Results of the study showed that use of the ultrasound surgical aspirator may permit more patients to be optimally cytoreduced.
