Summary
Loop electrocautery excisional procedure (LEEP) follow-up is often abnormal, with high-grade squamous intraepithelial lesions (HSIL) occurring frequently. Margin status is a poor predictor of follow-up results, emphasizing the need for vigilant patient monitoring.
Area of Science:
- Gynecology
- Oncology
- Pathology
Background:
- Loop electrocautery excisional procedure (LEEP) is a common treatment for cervical dysplasia.
- Assessing the adequacy of LEEP margins is crucial for determining the risk of residual or recurrent disease.
Purpose of the Study:
- To evaluate the outcomes of LEEP procedures.
- To determine the incidence of abnormal follow-up results after LEEP.
- To assess the relationship between margin status and abnormal follow-up findings.
Main Methods:
- A retrospective review of 162 LEEP procedures performed between January 1992 and April 1994.
- Evaluation of margin readability and status on all LEEP specimens.
- Examination of all subsequent cytologic or histologic follow-up specimens.
Main Results:
- After a mean follow-up of 10.9 months, 33.3% of patients had abnormal follow-up results, including high-grade squamous intraepithelial lesions (HSIL) in 13.2%.
- Of the cases with abnormal follow-up, 68.5% had readable margins, and 32.4% of these readable margins were positive.
- A significant 25.3% of LEEP procedures had no documented follow-up.
Conclusions:
- The high rate of HSIL post-LEEP underscores the necessity of diligent follow-up protocols.
- Margin status is an unreliable predictor of abnormal follow-up outcomes due to thermal artifact and negative margins in cases with recurrence.
- The lack of follow-up in a substantial portion of LEEP cases is a critical concern that requires immediate attention.
