伤寒患者回盲部的B型超声显像

目的探讨伤寒患者回盲部的Ｂ型超声显像特点。方法以伤寒病回肠末端淋巴组织病变最为显著的病理特点为依据,对发热４天以上患者,首先应用高频Ｂ超进行检查。结果最终确诊的１０９例成人伤寒病患者中,回肠末端肠壁增厚、规则、肠壁回声减弱,伴有周围淋巴结肿大者１０６例,敏感性达９７．２５％。同时对２００例非伤寒病患者进行对比检查,无假阳性。结论超声显像对伤寒病的早期诊断价值很大,可作为首选检查项目

B mode ultrasonic imaging of ileocecum in typhoid patients

Objective To evaluate the ultrasonic imaging characteristics of ileocecum in typhoid patients. Methods Based on the most outstanding pathological characteristics of the lymph tissue at the terminal part of ilem in typhoid, the patients with fever more than four days were examined by high frequency B mode ultrasound at first. Results The diagnosis of typhoid was confirmed at last in 109 adult. It was found in 106 patients the wall of the terminal ileum became thick, regular and hypoechoic. The surrounding lymph nodes were enlarged. The sensitivity was 97.25%. Meanwhile, 200 non typhoid patients were examined as control, no false positive was found. Conclusions For the early diagnosis of typhoid, ultrasonic imaging is very valuable and is the method of first choice.
