Abstract: Objective To explore the clinical value of spiral CT in diagnosis of acute early gastrointestinal perforation.Methods The clinical data of 38 patients who were definitely diagnosed by pathology as acute early gastrointestinal perforation were retrospectively analyzed.All the patients received spiral CT and abdominal X-ray before surgery.The diagnosis and imaging finding of two methods were analyzed.Results The accuracy of spiral CT (89.5％) was significantly higher than that of X-ray(63.2％) (x2 =7.28,P ＜0.01).X-ray did poorly at displaying free gas at small amount and structures which was not subdiaphragmatic air but retroperitoneum or less omental,but spiral CT did good at that obviously so as to make accurate location and etiological diagnosis.Conclusion Spiral CT can display a small amount of abdominal free air earlier and more accurately,with a high accuracy of diagnosis at early gastrointestinal perforation,and can provide valuable information for location and etiological diagnosis.
