A Study of Two Cone Biopsy Techniques For Women With Cervical Pre-Invasive Disease. LLETZ Cone and SWETZ.
In Brief
A Phase 3 clinical trial evaluating Straight Wire Excision of Transformation Zone and Large Loop Excision of Transformation Zone (cone biopsy) for Cervical Intraepithelial Neoplasia. Completed, enrolled 103 participants across 2 sites.
Detailed Summary
The purpose of this trial is to determine whether SWETZ (Straight Wire Excision of Transformation Zone) is a superior alternative to LLETZ cone (Large Loop Excision of Transformation Zone cone biopsy) in the management of pre-invasive endocervical disease. SWETZ is a new cone biopsy procedure performed with a straight wire electrode and it will be compared to LLETZ cone, which is performed with a large loop electrode.
Study Details
Timeline
Interventions
Straight wire excision of transformation zone is a electrosurgical conization method,which uses a straight wire electrode as a knife to remove the dysplastic epithelium of the cervix.
LLETZ cone is a electrosurgical conization method, which is performed with a large loop electrode of 20-25 mm depth. The loop is applied to the cervix outside the lateral margin of TZ and brought slowly to the controlateral TZ margin.
