目的探讨分析口服等渗甘露醇水溶液多层螺旋CT(MSCT)对小肠肠壁增厚性病变的诊断价值。方法 36例疑似小肠肠壁增厚性病变患者,采取等渗甘露醇水溶液做口服充盈小肠,再实施MSCT检查,评估患者十二指肠、空肠、回肠CT检测评分,评估患者小肠扩张效果,分析小肠病变诊断情况。结果口服等渗甘露醇水溶液进行小肠MSCT检查,患者十二指肠、回肠、空肠以及小肠总体扩张效果良好,经MSCT诊断,36例疑似小肠肠壁增厚性病变者中13例MSCT诊断呈阴性结果 ,并联合临床表现及随访情况排除小肠肠壁增厚性病变。其余23例患者诊断,其中Crohn病10例,小肠节段性肠壁增厚;肿瘤性病变10例(小肠腺癌4例,间质瘤5例,淋巴瘤1例);小肠梗阻3例。结论口服等渗甘露醇水溶液实施MSCT检查可有效检出小肠肠壁增厚性病变,无不良反应症状,小肠肠道扩张效率良好,提高影像学诊断质量,应用前景良好。
Objective To investigate the value of multi-slice spiral CT (MSCT) of oral isotonic mannitol in the diagnosis of small bowel wall thickening lesions. Methods Thirty - six patients with suspected small intestinal wall thickening lesions were treated with isotonic aqueous solution of mannitol to fill the small intestine orally. Then, MSCT was performed to evaluate the duodenum, jejunum and ileum CT, to evaluate the small intestine expansion. Small intestinal disease diagnosis. Results The small intestine MSCT was performed in oral solution of isotonic mannitol. The overall dilatation of duodenum, ileum, jejunum and small intestine was good. MSCT diagnosis was negative in 13 of the 36 patients with suspected small intestinal wall thickening lesions Results, combined with clinical manifestations and follow-up cases excluded small bowel wall thickening lesions. The remaining 23 patients were diagnosed, of which Crohn disease in 10 cases, intestinal segment thickening of the intestinal wall; tumor lesions in 10 cases (4 cases of intestinal adenocarcinoma, stromal tumor in 5 cases, 1 case of lymphoma); intestinal obstruction in 3 cases. Conclusion MSCT of oral isotonic mannitol solution can effectively detect small bowel wall thickening lesions, no adverse reaction symptoms, good intestinal intestinal expansion efficiency, improve the diagnostic quality of imaging, the application prospect is good.
