CT对盆腔病变经阔韧带及乙状结肠系膜的腹膜下间隙蔓延的研究

Investigation of Spread of Disease via the Subperitoneal Space of the Broad Ligament and Sigmoid Mesocolon in the Pelvis by CT

目的 :评价CT对盆腔病变经韧带及乙状结肠系膜的腹膜下间隙蔓延的诊断价值。材料与方法 :分析 12 2例经手术病理或CT表现证实的盆腔阔韧带及乙状结肠系膜的腹膜下病变。结果 :病变侵犯乙状结肠系膜时 ,恶性病变远多于良性病变 (P <0 0 1) ;病变侵犯阔韧带时 ,良恶性病变之间无显著差异 (P >0 0 5 )。结论 :CT检查可清楚显示盆腔病变经阔韧带及乙状结肠系膜蔓延的韧带及系膜增厚、积液、肿块侵犯、血管模糊 。

Purpose:To investigate the value of CT in the diagnosis of spread of disease via the subperitoneal space of the broad ligament and sigmoid mesocolon in the pelvis.Materials and Methods:CT findings of spread of disease via the subperifonal space of the broad ligament and sigmoid mesocolon of the pelvis in 122 cases proved by pathology and CT were retrospectivey analysed.Results:There was a statistical significance between malignant and benign lesions when the sigmoid mesocolon was invaded(P<0 01);The difference was not statistically significant between malignant and benign lesions when the broad ligament was invaded (P>0 05).Conclusion:CT is useful in showing the thickening and fluid collections of the ligament and sigmoid mesocolon,mass lesions,indistinct vessels ,which suffered from the spread of disease via the subperitoneal space of the broad ligament and sigmoid mesocolon in the pelvis.CT is an important noninvasive tool for making a difference between malignant and benign lesions and staging of tumors.
