Endometrial cytohistology by the pistol-aspiration technique: clinical applicability.
The purpose of this study was to assess the value of the endometrial pistol-aspiration technique as an office procedure for diagnosing corpus uteri cancer in symptomatic and asymptomatic women. Review of 3000 pistol aspirations in symptomatic outpatient women from 1974-1981 confirms that this method, with its high specificity and sensitivity, can be used for such women as a preliminary diagnostic procedure, eliminating risks from anesthesia and curettage as well as the cost of hospitalization. Analysis of resident incident cases shows that 82% were localized to the uterus, and more than 85% of these women were already symptomatic. Older women represent particularly difficult problems, both technical (cervical stenosis) and in recruitment. Because the natural history of the precursor lesions of corpus uteri cancer are not yet well established, use of this method for systematic population screening of asymptomatic women is questionable.
