Abstract:

Objective To discuss the diagnostic value of abdominal ultrasound combined with multi-slice spiral computed tomography (MSCT) in acute appendicitis. Method the clinical data of 80 patients with acute appendicitis admitted to the outpatient department of the fourth retired cadre sanatorium of Dalian military region of Liaoning Province from January 2022 to January 2025 were retrospectively selected. All patients underwent abdominal ultrasound and MSCT examination. Taking the pathological results as the gold standard, the diagnostic value of abdominal ultrasound combined with MSCT for acute appendicitis was analyzed. Result The surgical pathology confirmed that among 80 patients with acute appendicitis, 14 cases were simple appendicitis, 37 cases were suppurative appendicitis, 24 cases were gangrenous appendicitis, and 5 cases were periappendiceal abscess; The accuracy of abdominal ultrasound combined with MSCT in detecting simple appendicitis, suppurative appendicitis and gangrenous appendicitis was higher than that of single examination (P ＜ 0.05); When examining the abscess around the appendix, the accuracy rate of combined examination was higher than that of single examination, but the difference was not statistically significant (P ＞ 0.05). Conclusion Abdominal ultrasound combined with MSCT in the diagnosis of acute appendicitis can improve the accuracy and reduce the incidence of missed diagnosis and misdiagnosis.
