Objective: To assess frequency of and identify risk factors for the development of cervical stenosis after loop electrosurgical excision procedure.

Methods: We reviewed outpatient charts of women treated by loop excision for cervical dysplasia between August 1996 and January 1998 in the colposcopy clinic at Massachusetts General Hospital. One hundred sixty-four women were evaluated for cervical stenosis during follow-up. Stenosis was considered present if manual dilation was required to allow endocervical sampling with an endocervical currette 3 mm wide. Multivariable analysis with stepwise logistic regression was used to evaluate age, parity, tobacco use, hormonal status, use of oral contraceptives, pathology, previous loop excision, performance of additional endocervical excision, and dimensions of excision specimens as predictors of cervical stenosis.

Results: The average age was 32 years. Cervical stenosis occurred in ten of 164 women (6%, 95% CI 3%, 11%). Among factors analyzed, previous loop excision and volume of excision specimen were the only independent predictors of stenosis.

Conclusion: Cervical stenosis correlated with history of loop excision and volume of tissue removed, suggesting that women who have second excisions or large excisions should be counseled that their risk of stenosis might be higher.
