A method to improve the accuracy between the presumed depth of excision and the actual depth of excision in women receiving LLETZ cervical treatment; a single-center, two-operator experience.

Background: We aimed to determine whether continuous auditing of the presumed depth of excision and comparing with the actual depth of excision in women having large loop excision of the transformation zone (LLETZ) improves the ability to acquire the desired depth of excision.

Methods: This was a prospective study of women submitted to a single LLETZ treatment between 2017-2018. Two senior colposcopists recorded what they presumed was the depth of excision at the time of treatment and the subsequent histopathology report provided the actual excised depth.
