  • Title: [Radionuclide scintigraphy in etiologic diagnosis of gastrointestinal bleeding in children].
    Author: Zhao M, Wu HH, Weng Y.
    Journal: Zhonghua Yi Xue Za Zhi; 1997 Jan; 77(1):47-9. PubMed ID: 9596978.
    Abstract:
    OBJECTIVE: To assess the role of radionuclide scintigraphy in etiologic diagnosis of gastrointestinal bleeding in children, especially in detecting the cases of Meckel's diverticulum or double intestine. METHODS: 99mTc-pertechnetate abdominal scintigraphy was undertaken in 26 children with history of gastrointestinal bleeding. Additional 99mTc-RBC scintigraphy was performed in 12 cases who gave a negative 99mTc-pertechnetate scintigraphy as they had the signs of active bleeding. The final diagnosis of all cases was proved by surgery and pathology or endoscopy. RESULTS: In detecting Meckel's diverticulum and double intestine, the sensitivity, specificity and accuracy of 99mTc-Pertechnetate scintigraphy were 85. 7% (12/14), 91.7% (11/12) and 88.5% (23/26) respectively. CONCLUSION: Radionuclide scintigraphy may be the first procedure to explore the etiology in the lower digestive tract.
