Tracheloscopically directed biopsy of the endocervical canal in stage II adenocarcinomas of the endometrium.

Endoscopic inspection of the endocervical canal (tracheloscopy) appears to be a rapid, reliable diagnostic technique to confirm the presence of endometrial neoplasms involving the endocervix found at fractional curettage. A series is presented in which 68% of patients with "positive" endocervical curettage were found to have no involvement of the endocervix by tracheloscopy and biopsy, which was confirmed by subsequent hysterectomy. The technique is discussed, and the use of this procedure in the staging of endometrial malignancies is recommended.
