急性阑尾炎的超声诊断分析

Ultrasound diagnosis of acute appendicitis

目的探讨急性阑尾炎的超声诊断。方法对106例临床上高度怀疑急性阑尾炎的患者进行B超检查,分析其声像图特点并与术后病理进行对照。结果 106例中92例超声检查有明显的右下腹异常包块阳性发现,8例超声表现为右下腹肠管扩张并少许游离液性暗区,6例超声腹腔见大量气体回声,超声无明显发现,误诊2例。根据其病程的长短及超声图像的不同表现,可以分成急性单纯性阑尾炎、急性化脓性阑尾炎、急性坏疽性阑尾炎、阑尾周围脓肿四种类型。结论 B超检查在急性阑尾炎的诊断及鉴别诊断中有重要的临床价值。

Objective To probe into the ultrasonic diagnosis of acute appendicitis. Methods Given B-uhrasonic examination 106 cases patients clinically highly suspected with acute appendicitis, analyzed its ultrosonographic features and com- paring with postoperative pathology. Results Of 106 cases, abnormal echo mass in the right lower quadrant could be seen on 92 cases of ultrasound patients;8 cases of them showed the limited expansion of bowel tube, combined with a bit of free fluid shadowed areas; gas multiple reflections could only be seen on 6 cases of them without significant ultrasound findings. According to their different stages of pathology and course of disease and sonographic features, they are divided into acute simple appendicitis, acute suppurative appendicitis, acute gangrenous appendicitis, appendiceal abscess. Conclusion Ultrasonography has important clinical value for acute appendicitis diagnosis and differential diagnosis.
