Summary
Cervical stenosis risk is higher with deeper excisions and entirely endocervical lesions. Loop electrosurgical excision (LEEP) may reduce this risk due to shallower excision depths compared to laser conization.
Area of Science:
- Gynecology
- Surgical Oncology
- Colposcopy
Background:
- Cervical stenosis is a potential complication following treatments for cervical intraepithelial neoplasia.
- Laser conization and loop electrosurgical excision procedure (LEEP) are common treatment modalities.
Purpose of the Study:
- To evaluate the incidence of cervical stenosis after laser conization and LEEP.
- To identify preoperative and treatment-related factors associated with cervical stenosis development.
Main Methods:
- A comparative study of 255 women treated with laser conization and 277 with LEEP.
- Regular postoperative colposcopy follow-up for a mean of 38 and 16 months, respectively.
- Stenosis defined as cervical narrowing preventing a 2.5-mm Hegar dilator insertion.
Main Results:
- Thirty-eight cases of cervical stenosis were diagnosed.
- Higher risk of stenosis observed in patients over 50, with totally endocervical lesions, and with excisions ≥20 mm high.
- Laser conization was associated with a higher risk of stenosis compared to LEEP.
- Multivariate analysis identified excision height and totally endocervical lesions as independent risk factors.
Conclusions:
- The primary factors contributing to cervical stenosis are the depth of excision and the presence of a totally endocervical lesion.
- LEEP may offer a reduced risk of cervical stenosis, potentially due to shallower endocervical excision compared to laser conization.
