AbstractThe application of loop electrosurgical excision procedure (LEEP), a new method of conization of the uterine cervix used to diagnose cervical intraepithelial neoplasia (CIN) or cervical cancer is presented herein. A loop electrode consists of a thin wire that allows deep excision of the transformation zone (TZ). The cone-shaped tissue removed can be examined histologically. Over a period of one year, a total of 41 cases underwent LEEP. Without anesthesia, the patients did not have any noticeable pain during the procedure. There were no complications, such as fever, wound infection, massive bleeding or cervical stenosis. In low-grade CIN, follow-up colposcopy and cytology did not show persistence or recurrence. In two cases of high-grade CIN, subsequent hysterectomy revealed residual lesions on hysterectomized specimens. LEEP is a simple and quick procedure of diagnostic conization that can be done at the first visit without major complication. If the histopathology after LEEP is moderate- to high-grade CIN or invasive cancer, the conization cannot be regarded as a sufficient therapeutic procedure, and such a patient needs further treatment.
