目的探讨不同类型腹内疝特征 性MSCT表现特点。方法 回顾性分析我院 2015年1月-2018年1月收治的1310例急腹 症患者临床资料，应用飞利浦多层螺旋 CT诊断。结果 1310例急腹症患者中共检 出12例(0.92%)腹内疝，其中8例(66.67%) 腹内疝进行增强扫描。12例腹内疝患者出 现不同程度的肠梗阻，其中2例(16.67%) 患者肠管明显扩张，积液成襻，MSCT图 像为“咖啡豆”特征或“假肿瘤”。3 例(25.00%)患者出现肠系膜血管改变， 其中1例(33.33%)患者肠系膜聚集、移 位，1例(33.33%)患者肠系膜扭曲，1例 (33.33%)患者肠系膜增粗伴系膜脂肪密 度增高，MSCT特征为“血管纠集征”。3 例(25.00%)患者出现肠管缺血，其中1例 (33.33%)患者肠壁缺血，1例(33.33%)患 者合并缺水，1例(33.33%)患者肠壁密度 异常，MSCT图像特征为“同心圆”。4例 (33.33%)患者出现占位效应，小肠内容物 已经通过疝口，肠襻聚集扩张明显，其中 1例(25.00%)在左上腹、2例(50.00%）在 右上腹，1例(25.00%)在中上腹。MSCT诊 断正确率83.33%。结论 腹内疝患者出现 不同程度的肠梗阻，襻性肠梗阻MSCT图像 为“咖啡豆”，肠系膜血管改变特征为 “血管纠集征”，肠管缺血特征为“同心 圆”，占位效应特征为肠襻聚集扩张明 显。

Objective To investigate the MSCT Manifestations and features of Internal Hernia of different types. Methods The clinical data of 1310 cases of acute abdomen patients diagnosed with MSCT in our hospital from January 2015 to January 2018 were retrospectively analyzed. Results Among 1310 cases of acute abdomen patients, 12 patients had internal hernia, of which 8 cases (66.67%) received the enhanced scans. 12 patients with intra-abdominal hernia had different degrees of intestinal obstruction, of which 2 patients (16.67%) had significant dilatation of the intestine and effusions. The MSCT images were "coffee bean" or "pseudotumor". The mesenteric vascular changes occurred in 3 patients (25.00%), of which 1 case (33.33%) had mesenteric aggregation and displacement, 1 case (33.33%) had mesenteric twist, and 1 case (33.33%) had mesenteric enlargement with mesangial fat increased density, the MSCT featured as the "vascular collection syndrome." Intestinal ischemia occurred in 3 patients (25.00%), of which 1 case (33.33%) had intestinal wall ischemia, 1 case (33.33%) had combined water deficit, and 1 case (33.33%) had abnormal intestinal wall density. MSCT images featured as "concentric circles." 4 patients (33.33%) had occupying effect, the contents of the small intestine had passed through the fistula, and the intestinal fistula accumulated and expanded significantly. One case (25.00%) was in the left upper quadrant, 2 cases (50.00%) was in the right upper quadrant, and 1 case (25.00%) was in the middle and upper abdomen. The diagnostic accuracy of MSCT was 83.33%. Conclusion The patients with intra-abdominal hernia have different degrees of intestinal obstruction. The MSCT image of sputum intestinal obstruction is "coffee bean". The mesenteric vascular changes are characterized by "recruitment of blood vessels". The features of intestinal ischemia are "concentric circles". The space-occupying effect was characterized by a marked expansion of intestinal ridges.
