二维超声诊断不同类型肠梗阻

目的　探讨二维超声诊断机械性、动力性、血运性肠梗阻的价值。方法　应用二维超声检查 10例肠梗阻患者 ,其中 7例机械性、2例动力性、1例血运性肠梗阻。结果　①机械性肠梗阻超声表现为肠管扩张 ,肠腔积液 ,肠皱襞呈多条纹实性回声 ,肠蠕动亢进 ;②动力性肠梗阻除上述表现外 ,肠蠕动减弱乃至消失 ;③血运性肠梗阻除上述表现外 ,腹腔出现游离液体回声。结论　二维超声有助于诊断不同类型的肠梗阻

Two-dimensional sonography in different kinds of ileus

Objective To explore the manifestations of two-dimensional sonography in mechanical ileus,dynamic ileus and ischemic ileus.Methods Using two-dimensional sonography to examine 10 cases with ileus.There were 7 cases with mechanical ileus,2 cases with dynamic ileus,and 1 case with ischemic ileus among them.Results ① Mechanical ileus in ultrasound showed intestinal dilatation,intestinal effusion or hydrops,intestinal plicae as multistriped solid echo,and intes-tinal hyper peristalsis.② Dynamic ileus in ultrasound except the above-mentioned showed intestinal peristalsis weaken or vanish;③ Ischemic ileus in echo in addition to the above-mentioned showed free fluid in abdominal cavity.Conclusion Two-dimensional sonography contributes to the diagnosis of different kinds of ileus.
