The Isaacs Endometrial Cell Sampler. An evaluation in 100 patients with postmenopausal bleeding

The Curity Isaacs Endometrial Cell Sampler was used to obtain cytologic material from 100 consecutive patients presenting with postmenopausal bleeding. It was followed by uterine curettage to obtain material for histology. Satisfactory endometrial aspiration smears were obtained from 92 patients, whereas curettage yielded endometrial tissue in only 48. Of 17 patients with histologic confirmation of malignancy, 7 had smears diagnosed as showing malignancy, and 7 had smears showing hyperplastic changes; 3 of the aspiration smears were judged to be unsatisfactory for cytologic evaluation. All the carcinomas were found in the hyperplastic, malignant or unsatisfactory smears. This technique is worthy of further study.
