Abstract

Purpose

Ultrasound and multi-slice spiral computed tomography (CT) are frequently used to assist the diagnosis of acute appendicitis (AA), and the examination results may vary among different demographics. This study aimed to compare the diagnostic accuracy of ultrasound and CT for AA.

Methods

We performed a retrospective analysis of patients diagnosed with AA who underwent emergency surgery at our hospital from March 2021 to August 2023, with postoperative pathological results as the gold standard. Differences in the diagnostic accuracy of ultrasound and CT for different types of AA, age groups, and body mass index (BMI) values were then analyzed.

Results

The overall sample comprised 279 confirmed cases of AA, with 64 cases of simple appendicitis, 127 cases of suppurative appendicitis, and 88 cases of gangrenous appendicitis. For these three pathological classifications, the diagnostic accuracy of ultrasound was 68.75% (44/64), 73.22% (93/127), and 81.81% (72/88), respectively, while the diagnostic accuracy of CT was 71.87% (46/64), 82.67% (105/127), and 90.90% (80/88), respectively. There was no statistically significant difference in the overall diagnostic accuracy between the two methods (P > 0.05). Subgroup analysis showed no difference in diagnostic accuracy between the two methods for patients with normal BMI (P > 0.05). However, for overweight, obese, and elderly patients, CT provided significantly better diagnostic accuracy than ultrasound (P < 0.05).

Conclusion

While ultrasound and CT have similar diagnostic accuracy for different pathological types of AA, CT is more accurate for overweight, obese, and elderly patients.

急性阑尾炎的超声波和多层螺旋计算机断层扫描诊断价值评估：一项回顾性研究

目的超声波和多层螺旋计算机断层扫描（CT）常用于辅助诊断急性阑尾炎（AA），不同人群的检查结果可能存在差异。方法我们对 2021 年 3 月至 2023 年 8 月期间在我院接受急诊手术确诊为 AA 的患者进行了回顾性分析，并以术后病理结果作为金标准。结果总体样本包括 279 例确诊 AA 患者，其中 64 例为单纯性阑尾炎，127 例为化脓性阑尾炎，88 例为坏疽性阑尾炎。在这三种病理分类中，超声波的诊断准确率分别为 68.75%（44/64）、73.22%（93/127）和 81.81%（72/88），而 CT 的诊断准确率分别为 71.87%（46/64）、82.67%（105/127）和 90.90%（80/88）。两种方法的总体诊断准确率差异无统计学意义（P > 0.05）。分组分析显示，对于体重指数正常的患者，两种方法的诊断准确率没有差异（P >0.05）。结论虽然超声和 CT 对不同病理类型 AA 的诊断准确性相似，但 CT 对超重、肥胖和老年患者的准确性更高。
