| Objective:1.To evaluate the diagnostic effect of IOTA simple rule,ultrasound and ultrasound combined with IOTA simple rule for non-benign lesions of the ovary,and to compare.2.To investigate the ultrasonographic characteristics of borderline ovarian tumors and the predictive value of ultrasound combined with IOTA simple rule for borderline ovarian tumors.Methods:1.Ultrasonography of 196 inpatients with ovarian tumors undergoing surgery in the department of Obstetrics and Gynecology of Bethune Hospital of Shanxi Province were retrospectively analyzed,including 64 borderline ovarian tumors(4 bilateral,68 masses in total),87 benign ovarian tumors,and 45 malignant ovarian tumors.2.The ultrasound images of 68 borderline ovarian tumors were analyzed and judged by two senior sonographers according to the following two methods when the pathological results were unknown:(1)Ultrasound evaluation: one senior sonographer made ultrasonic judgment based on subjective experience;(2)Ultrasound combined with IOTA simple rule evaluation: Another ultrasound doctor with the same senior experience first made judgment based on IOTA simple rule,and then made subjective experience judgment on the uncertainty types in the results.3.Using pathological results as the gold standard,the diagnostic coincidence rate of ovarian non-benign lesions and borderline ovarian tumors obtained by the above methods was compared.4.Taking benign ovarian tumor,borderline ovarian tumor and malignant ovarian tumor as dependent variables,univariate analysis and multivariate disordered logistic regression analysis were performed on the related variables involved in IOTA simple rule.Results:1.68 borderline ovarian tumor ultrasound images were determined by ultrasound,namely subjective experience: 35 benign,30 borderline and 3 malignant ovarian tumors.The coincidence rate of non-benign lesions was 48.5%(33/68),and the coincidence rate of ovarian borderline tumors was 44.1%(30/68).2.68 borderline ovarian tumor ultrasound images were determined by IOTA simple rule: 21 benign ovarian tumors,10 malignant ovarian tumors,and 37 uncertain ovarian tumors.Uncertain ovarian tumors were classified as malignant ovarian tumors,and the coincidence rate of non-benign lesions was 69.1%(47/68).3.68 borderline ovarian tumor ultrasound images were determined by ultrasound combined with IOTA simple rule: 22 benign,35 borderline and 11 malignant ovarian tumors,the coincidence rate of non-benign lesions was 67.6%(46/68),and the coincidence rate of borderline ovarian tumors was 51.4%(35/68).4.The coincidence rates of non-benign lesions in IOTA simple rule,ultrasound and ultrasound combined with IOTA simple rule were statistically significant(P<0.05),pair-to-pair comparison: there was no statistical difference in the coincidence rate of non-benign lesions between IOTA simple rule and ultrasound combined with IOTA simple rule(P>0.05);there was statistically significant difference between IOTA simple rule and ultrasonic diagnosis coincidence rate of non-benign lesions(P<0.05);there was statistically significant difference in the diagnostic coincidence rate between ultrasound and ultrasound combined with IOTA simple rule for non-benign lesions(P<0.05).5.There was statistically significant difference in the coincidence rate of diagnosis of borderline ovarian tumor between IOTA simple rule and ultrasound(P<0.05).6.Univariate analysis showed that papilla,dense septum and blood flow were the influential factors in judging benign,borderline and malignant ovarian tumors(P<0.05).Multivariate disordered logistic regression analysis showed that borderline ovarian tumors had more papilla,dense septum and blood flow than benign tumors(P<0.05).Compared with malignant tumor,blood flow probability was lower(P<0.05).Conclusions:1.IOTA simple rule diagnosis of ovarian non-benign lesions has a high coin cidence rate,which can reduce the missed diagnosis of non-benign lesions,and is an effective method to guide ultrasound doctors with low experience to make ob jective judgment of benign and malignant tumors.2.Ultrasound combined with IOTA simple rule can improve the diagnostic c oincidence rate of borderline ovarian tumor by combining objective method with s ubjective experience,which has important value for preoperative prediction of bor derline ovarian tumor.3.Nipple,dense septum and blood flow may be the specific ultrasound ima ges for diagnosing ovarian borderline tumors. |
