Is large loop excision of the transformation zone depth a risk factor for affected endocervical margins?

Objective: The aim of the study was to determine if the depth of large loop excision of the transformation zone (LLETZ) is a risk factor for presenting affected endocervical margins.

Methods: A cross-sectional retrospective study was performed on 353 patients that underwent LLETZ after presenting cervical biopsies with CIN grade 2 and grade 3 or persistent CIN grade 1 at Hospital Universitario Santa Lucía, Cartagena, Spain, from November 2011 to December 2016. Automatized measurement of the LLETZ depth was performed in microns and added to cervical canal extensions when these were performed.

Does the trend toward less deep excisions in LLETZ to minimize obstetric risk lead to less favorable oncological outcomes?

Objective: To analyze the relationship between large loop excision of the transformation zone (LLETZ) depth and the persistence of disease and human papillomavirus (HPV) infection in patients with cervical intraepithelial neoplasia grades 2 and 3.

Methods: A cross-sectional observational retrospective study included women with cervical intraepithelial neoplasia grades 2 and 3 who underwent LLETZ at Hospital Universitario Santa Lucía, Cartagena, Spain, from November 1, 2011, to December 31, 2016. Follow-up of cytology and HPV detection were performed at 6 and 12-18 months after surgery.
