Clinical evaluation of the Endosearch sampler in endometrial cytology-a preliminary report

The clinical value of the Endosearch endometrial cell sampling device was assessed in 94 cases managed in our outpatient clinic. The Endosearch could be easily inserted into the uterine cavity in 91 (96.8%) of 94 cases without analgesia. Pain and prolonged bleeding accompanied by the insertion of the Endosearch occurred in eight (8.8%) and six (6.6%) of 91 cases, respectively. Satisfactory material for cytologic diagnosis of the endometrial state was obtained in 90(98.9%) of 91 cases, which were comparable to those with the Endocyte. On the other hand, the endometrial tissue samples could be simultaneously obtained with the Endosearch in 78 (85.7%) of 91 cases, and histologic diagnosis was possible in 69(88.5%) of 78 cases. Among them, three of five cases with endometrial hyperplasia and four of five cases with endometrial carcinoma could be correctly diagnosed by the Endosearch histologically. These results suggest that outpatient investigation of the endometrial state by the Endosearch sampler is quite useful not only in cytologic diagnosis but also in histologic evaluation of endometrial lesions.
