Introduction: Invagination is the most common cause of acute abdomen and the second common cause of intestinal obstruction in the children under the age of two years, and the delay in diagnosis and treatment can be dangerous and even fatal. The aim of this study is to estimate the exact value of the diagnostic clinical and radiological findings in order to speed up the diagnosis of this emergency issue.
Methods: This cross-sectional study was performed on 160 patients diagnosed with invagination. After collecting the data ,sensitivity, specificity and the positive and negative predictive values of clinical and radiological findings were calculated using SPSS software.
Results: 63.1% of the patients were boys and most of cases were 10-50 months old. In 21.9% of the patients, three major clinical findings (triad) existed simultaneously: colicky abdominal pain, abdominal mass, currant-jelly stool. Ultrasonography and barium enema had the diagnostic sensitivity of: 69.3, 87.9, 91.4, 83.3 and 94.4 percent, specificity of 20, 39.2, 45.6, 27.7 and 88.9 percent, positive predictive value of 85.8, 45.1, 56.6, 87.6, and 97.1 percent, and also negative predictive value of 8.5, 85.1, 87.2, 65.3 and 80 percent, respectively.
Conclusion: Our study showed that in contrast to other world centers, the usage of barium enema was more frequent and of less curative value. Futhermore, in this study ultrasonography has not been used for all patients and its diagnostic value has been less than barium enema. Considering the important role of ultrasonography in diagnosing and treating the disease in recent years, training residents and specialists of radiology and even other specialities of medicine (such as pediatrics and surgery) is a necessity
