Abstract：Objective: To analyze the ultrasonic findings of acute abdominal diseases and the causes of misdiagnosis. Methods: 100 cases of patients with acute abdominal diseases treated in our hospital from April 2012 to May 2017 were selected and examined with color Doppler ultrasonography. According to the features of ultrasonic images, the types of acute abdominal diseases were diagnosed, and the results were compared with the diagnosis results of operation and pathology. The accuracy and misdiagnosis rate of ultrasonic diagnosis of acute abdominal diseases, and the causes of misdiagnosis were analyzed. Results: According to the sites, size, echo and blood flow images of lesions displayed by ultrasound, it was found that the ultrasonic findings of patients with acute abdominal diseases caused by different causes were obvious. The postoperative pathological diagnosis of 100 patients with acute abdominal diseases showed 19 cases of urinary calculi, 18 cases of hepatic stones and gallstones, 15 cases of acute appendicitis, 11 cases of acute cholecystitis, 10 cases of acute pancreatitis, 10 cases of intestinal obstruction, 12 cases of intestinal perforation, 5 cases of ectopic pregnancy and ovarian torsion, and 1 case of abdominal large vascular disease. The accuracy rate of ultrasonic diagnosis was 84.00%, and the misdiagnosis rate was 16.00%. Among the misdiagnosed patients, there were 2 cases of urinary calculi misdiagnosed as chronic colitis and intestinal obstruction, 1 case of gallstone misdiagnosed as intestinal polyps, 1 case of acute appendicitis misdiagnosed as urinary calculi, 2 cases of acute cholecystitis misdiagnosed as gallstones and cholestasis, 1 case of acute pancreatitis misdiagnosed as intestinal fistula, 1 case of intestinal obstruction and 1 case of intestinal perforation misdiagnosed as acute appendicitis, 2 cases of ectopic pregnancy misdiagnosed as purulent appendicitis and early pregnancy, 3 cases of ovarian torsion misdiagnosed as purulent appendicitis, appendix perforation and early pregnancy, and 1 case of abdominal large vascular disease misdiagnosed as ectopic pregnancy. The causes of misdiagnosis mainly includes poor ultrasonic findings, non obvious signs, atypical ultrasonic features or similar diseases. Conclusion: The accuracy rate of Doppler ultrasound is high in the diagnosis of acute abdominal diseases. However, poor ultrasonic findings, non obvious signs and atypical ultrasonic features may cause misdiagnosis. Other ways can be used for differential diagnosis.
