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.
期刊介绍：
Abdominal Radiology seeks to meet the professional needs of the abdominal radiologist by publishing clinically pertinent original, review and practice related articles on the gastrointestinal and genitourinary tracts and abdominal interventional and radiologic procedures. Case reports are generally not accepted unless they are the first report of a new disease or condition, or part of a special solicited section.
Reasons to Publish Your Article in Abdominal Radiology:
· Official journal of the Society of Abdominal Radiology (SAR)
· Published in Cooperation with:
European Society of Gastrointestinal and Abdominal Radiology (ESGAR)
European Society of Urogenital Radiology (ESUR)
Asian Society of Abdominal Radiology (ASAR)
