Clinical treatment on residues after CIN conization

Objectives: To explore on the factors and clinical treatment of residues after CIN conization surgery. Methods: We studied 20 patients with excision margin residues and 121 patients without excision margin residues who have received CIN conization surgery in our hospital between January 2007 and December,2009,to understand the relationship between CIN coniza- tion residues and positive excision margins,degree of pathological changes and expertise of the surgeon. Results: Among 141 studied cases,20 cases showed excision margin residues( 14. 1% ) of which 15 cases having severe cervical erosion ( 32% ) , while 121 cases indicated no margin residues of which 42 cases having severe cervical erosion ( 15. 2% ) . General surgeon performed 54 conization among the 141 cases. There are 13 cases of positive excision margin,the rate being 24% . Specialized surgeon performed 87 cases of conization,with 7 cases of positive excision margin ( 8% ) . Conclusion: CIN conization residues should be detected with HPV DNA and vaginoscopy to determine whether the secondary conization is necessary.
