OBJECTIVE: To quantify and analyse the influence of a histological report of incomplete excision of CIN after LLETZ on frequency of detection of residual CIN. DESIGN: Review of a computerised database of sequential women treated by LLETZ. Initial follow-up was three months post-treatment. SETTING: The Colposcopy Clinic, Regional Department of Gynaecological Oncology, Queen Elizabeth Hospital, Gateshead, Tyne and Wear, UK. SUBJECTS: 721 women with CIN diagnosed histologically on LLETZ specimens. RESULTS: In spite of a first time treatment success rate of 95% at 3 months, only 56% of the women were reported to have complete histological excision of CIN. A report suggesting incomplete excision was more likely with more severe CIN, extensive lesions and involvement of the endocervical canal. Furthermore, 21% with residual CIN had apparent complete excision of CIN at LLETZ. CONCLUSIONS: A histological report of incomplete excision of CIN at LLETZ does not equate with residual disease. The high treatment success rate of LLETZ means that a report of incomplete excision should stimulate close colposcopic and cytologic follow-up to identify the small number of women with residual CIN after therapy.
