Abstract:
The objective of our study was to determine whether removing multiple pieces of cervical tissue during large loop excision of the transformation zone (LLETZ) reduced the margin positivity of excision and cytology recurrence rates at follow-up. We conducted an observational cohort study and identified 462 women having had a single LLETZ treatment for cervical intraepithelial neoplasia (CIN) over a two-year period. Women with previous cervical treatment, cervical cancer on the excised tissue or missing follow-up data were excluded. Multiple regression analysis showed that removal of cervical tissue in multiple pieces did not offer any benefit in removing more disease and less recurrence rates. When multiple pieces were taken there was a four-fold increased risk for inconclusive excision margins as reported by the histopathologist. Removal of multiple pieces led to significantly more tissue being removed which may expose the patient to an increased risk of preterm delivery in a future pregnancy.
