4.2 Strengths and limitations
A number of studies have analyzed the influencing factors associated with positive cone margin. However, to our knowledge, this study is the first study on the problem of making additional cuts in cervical conization.
There are limitations of this study. This analysis only refers to 965 pathology reports at the First Affiliated Hospital of Dalian Medical University (Dalian, China), and only 64 doctors involved in. Moreover, there are rare studies on the publications of additional cut in cervical conization, resulting in a lack of research in other hospitals or regions has not been investigated, the generalizability of the results is uncertain. We cannot definitively say that additional cut can reduce the occurrence of positive margin in conization to some extent. A retrospectively Korean study of 65 cases performed that conization type and cone volume were statistically significant for preterm delivery13, but we unable to investigate whether additional cuts have an impact on preterm delivery due to a lack of follow-up of patients.
