CT、DR、超声检查在诊断肠梗阻的临床应用

Comparison the clinical application of CT,DR,US examination in the diagnosis of intestinal obstruction

目的研究CT、DR及超声检查对诊断肠梗阻的临床价值。方法回顾性分析105例临床拟诊肠梗阻患者的CT、DR及超声检查结果并与临床最终结果对比分析。结果 105例拟诊患者中临床最终明确肠88例。CT诊断梗阻83例,明确梗阻部位75例、明确梗阻原因78例。DR诊断76例,明确梗阻部位66例、明确梗阻原因32例。超声检查具有"肠管明显扩张、肠间积液"等表现且提示肠梗阻13例,明确梗阻部位及原因5例。结论对临床拟诊肠梗阻的患者,CT比常规DR和超声检查具有明显优势;对肠梗阻患者行疗效观察,可选择CT增强扫描联合超声动态检查。

Objective To evaluate the clinical application for detecting the intestinal obstruction with computed tomography（CT）,digital radiography（DR） and ultrasound（US）.Methods 105 patients suspected with intestinal obstruction were retrospectively analyzed of their CT,DR and US features,which were compared with clinical outcomes.Results 88 cases were confirmed finally by clinical outcomes.83 cases were found by CT,76 cases by DR and 13 cases by US.Obstructive locations were detected in 75 patients with CT,66 cases with DR and 5 cases with US,respectively,the causes of obstruction can be explained in 78 patients with CT,32 cases with DR and 5 cases with US,in addition,the obstructive signs such as intestine dilatation and effusion in intestinal space could be demonstrated with US.Conclusion When intestinal obstructions were clinically suspected,CT examination may be superior to the conventional DR and US.Furthermore,CT enhancement scanning combined with dynamic US may be useful for following up the intestinal obstructions.
