CT在不典型急性阑尾炎诊断中的临床价值

The Clinical Value of CT in the Diagnosis of Non-typical Acute Appendicitis

目的探讨CT扫描在急性阑尾炎诊断中的临床价值。方法回顾性分析50例急性阑尾炎的临床表现、CT扫描特征和手术资料。结果50例急性阑尾炎中,CT扫描诊断为可疑急性阑尾炎1例(2.0%),单纯急性阑尾炎18例(36.0%),急性阑尾炎并阑尾周围炎9例(18.0%),急性阑尾炎并穿孔5例(10.0%),阑尾脓肿6例(16.0%),合并回盲部及升结肠肿瘤3例(5.0%),盆腔炎3例(5.0%),宫外孕1例(2.0%);CT诊断与手术相符者43例,诊断符合率86.0%。结论CT扫描对急性阑尾炎的诊断,特别是对临床表现不甚典型的阑尾炎及其并发症的诊断具有较高的临床价值。

Objective To evaluate the clinical value of CT scan in the diagnosis of acute appendicitis. Methods The clinical manifestations, CT imaging characteristics and surgical data of 50 patients with acute appendicitis were analyzed retrospectively. Results Of these 50 cases all scaned by CT, one was suspicious with acute appendicitis, 18 cases were diagnosed with acute appendicitis;acute appendicitis accompanied with periappendicitis were found in 9 cases;acute appendicitis with perforation in 5 cases ;appendiceal abscess in 6 cases;tumor of ileocecum and ascending colon in 3 cases ; pelvic inflammation in 3 cases and one of ectopic pregnancy were diagnosed by CT.
