4.1 Main Findings
In this study, we observed that older age, shorter cone depth, making
additional cuts, the pathology result of conizaiton tissue was HSIL or
cervical cancer were independent risk factors for positive margin in
conization. We thought the additional cuts was the independent risk
factor of positive surgical margin, this was because in the included
cases, most patients with positive margin underwent additional cuts.
Among doctors, who have the habit of making additional cuts, their
additional cuts were overwhelmingly effective. Additionally, the cone
volume was significantly smaller, of the additional cuts cases and cases
made by doctors who had habit of making additional cuts.
