Schaefer K et al. – LLETZ during pregnancy can be performed if invasive cancer cannot be excluded by colposcopy, cytology, or biopsy. The procedure has a diagnostic intention but can also be a curative therapy in pregnancy, with low intraoperative, postoperative, and peripartum complication rates.Methods
- A retrospective study included 27 patients who underwent LLETZ during pregnancy for suspected high–grade squamous intraepithelial lesions (HSIL) where microinvasion could not be excluded.
- The study investigated intraoperative and postoperative complications, and compared preoperative and postoperative results.
- Questionnaires were used to obtain information about peripartum and postpartum data.
- Three (11.1%) women had invasive or microinvasive cancer, 22 (81.5%) had cervical intraepithelial neoplasia (CIN) 3, and 1 (3.7%) had CIN 2.
- Twenty–four were positive for high–risk human papillomavirus.
- All cervical cancers were classified as HSIL or CIN 3 before LLETZ. There were positive resection margins in 15 (55.6%) cases.
- No intraoperative complications occurred. One (3.7%) patient had a postoperative missed abortion.
- Major complications such as premature labor or cervical incompetence without influence on delivery occurred after LLETZ in 4 (14.8%) patients.
