Hysteroscopic Management of Congenital External Cervical Os Stenosis Using a "No-Touch" Technique in an Adolescent

Background: Congenital external cervical os stenosis, one type of congenital cervical atresia, is particularly rare, and no case has been documented so far. Case: A 12-year-old virginal patient with a history of mild vaginal bleeding for 14days and lower abdominal pain for 10days during her menarche was diagnosed with congenital external cervical os stenosis. Using a "no touch" technique, the diagnosis was further confirmed through a diagnostic hysteroscopy, and the narrow external cervical os was successfully corrected by resectoscopy, leaving the hymen intact. The patient was free of any symptoms postoperatively. Results and Conclusion: We discuss the above-mentioned case and data already published in the literature. Congenital external cervical os stenosis in non-sexually active patients can be managed by diagnostic and operative hysteroscopy using a "no touch" technique while keeping the hymen intact.
