Results Pneumoperitoneum was only shown in 10 cases out of 34 by X-ray examination, but 32 cases out of 34 by CT examination. CT examination detection rate was higher than ordinary X-ray examination ( P <0. 05). Furthermore, primary diseases were only shown in 3 cases by X-ray examination, but 24 cases by CT examination.
