Objectives: The current indications for conization of the cervix include a 2-step discrepancy between cervical cytological and histological findings. We sought to determine the utility of a loop electrocautery excision procedure (LEEP) cone for a 2-step discrepancy.
Methods: A retrospective institutional review board-approved chart review was performed on all women recommended to undergo a LEEP secondary to a discrepancy between a referral high-grade squamous intraepithelial lesion cytological finding and a subsequent colposcopic biopsy result revealing either normal or cervical intraepithelial neoplasia (CIN) 1 histological finding; CIN 2 was excluded from the study. Statistical analysis was performed using SAS 9 (SAS Institute, Inc, Cary, NC). The results were considered significant if a p value less than or equal to.05 was demonstrated.
Results: Fifty-nine patients received a LEEP for a 2-step discrepancy between cytological and histological findings. Twenty-seven patients had a second pass or LEEP cone. Among the patients with a normal cervical biopsy result and a high-grade cytological finding, 10 (29%) of 34 had normal histological findings, as revealed by LEEP, and 14 (41%) of 34 had CIN 3; 16 (64%) of 25 patients with high-grade cytological finding and CIN 1 biopsy finding had CIN 3, as revealed by LEEP. Compared with patients with an initial normal cervical biopsy result, those with CIN 1 on initial biopsy were more likely to have CIN 3 on their LEEP findings (p =.08). Twenty-seven of 59 patients underwent a LEEP cone surgery; 1 of 27 had CIN 3 finding in the second-pass portion. This was associated with a CIN 3 identified on the first pass and associated with positive margins. The second pass of the LEEP cone failed to demonstrate CIN 96% of the time (p < .0001). Patients with a normal or a CIN 1 finding on the first pass had a normal finding on the second pass in 100% of cases.
Conclusions: A LEEP cone is rarely indicated for the evaluation of a 2-step discrepancy. A randomized trial of this finding is warranted.

Unlabelled: The purpose of this study was to evaluate the incidence of AIS and AC in the histological cone of women treated for CIN3. Furthermore, through the study of the specific HR HPV genotypes, we obtained more information on the possible different nature between the single CIN3 lesion and the CIN3 coexisting with the glandular lesion.
Methods: A sample of 414 women underwent LEEP for CIN3.

Objective: To determine factors affecting obstetric outcomes in pregnancies after conization by loop electrosurgical excision procedure (LEEP) or cold-knife conization (CKC) due to cervical intraepithelial neoplasia.
Material And Methods: The maternal and clinical characteristics and obstetric outcomes of CKC, LEEP and control groups were evaluated and compared. Risk factors for adverse pregnancy outcomes were evaluated using multiple logistic regression analyses.

Article Synopsis
- Early management of high-grade cervical intraepithelial neoplasia is vital for cervical cancer prevention, with both loop electro excision (LEEP) and laser excision methods being effective techniques recommended for lesion removal.
- The study aimed to compare these two methods, focusing on the quality of surgical margins, and was conducted on 231 patients over an 8-year period.
- Results showed no significant difference in negative margin rates between the two techniques, but LEEP was associated with a shorter cone depth in excisions performed.
