Efficiency of ultrasornics in the diagnosis of gastrointestinal perforation

Objective: To evaluate the clinical value of sonographic diagnosis for gastrointestinal perforation.Methods: The manifestation of the sonography and the radiology of 32 patients operated on for gastrointestinal perforation was compared retrospectively.Results: The sonographic findings of the gastrointestinal perforation included free air,fluid and abnormal echo mass in the abdomen and the sensitivity rates were 84%(27/32),93%(30/32) and 68%(22/32),respectively.The diagnostic basis of gastrointestinal perforation by X-ray is free subdiaphragm air,with a sensitivity of 75%(24/32),but the mass and fluid were unable to be displayed.Conclusions: Detection of free air,fluid and irregular shaped mass in the abdomen by sonography can provide reliable attestation to the clinical diagnosis of gastrointestinal perforation.
