闭孔疝的多层螺旋CT术前诊断价值

Diagnostic values of multislice spiral CT in obturator hernia before operation

目的评价多层螺旋CT(MSCT)对闭孔疝的诊断价值。方法回顾性分析7例经手术证实的闭孔疝患者的MSCT表现。结果 7例患者均可见在闭孔外肌和耻骨肌之间出现疝囊,并伴有程度不等的肠梗阻,表现为小肠肠管扩张、积液,其中4例患者出现肠壁的缺血坏死,表现为肠壁增厚、水肿,增强扫描肠壁强化减弱,腹腔可见积液,2例患者出现小肠穿孔。结论 MSCT可准确诊断闭孔疝及其缺血坏死、穿孔等并发症,对术前评价有较大价值。

Objective To evaluate the value of multislice spiral CT（MSCT） in diagnosing obturator hernia.Methods The MSCT imaging features of 7 patients with obturator hernia were reviewed retrospectively.Results The presence of SBOs could be diagnosed in all patients on MSCT including dilation of the small bowel with fluid collection..Hernia sac were found between lateral obturator muscle and pectineus muscle..The thickening and swelling of the bowel wall and ascites which indicating ischemia were been seen in 4 patients..And perforations were found in 2 patients.Conclusion MSCT are not only useful for diagnosis of obturator hernia,but also useful for identifying the associated complications including ischemia and perforations of obturator hernia.
