Best diagnosis of the ectopic gastric mucosa of Meckel’s diveiculum is by
Correct Answer: Radionuclide scan
Description: Plain abdominal radiography, CT, and ultrasonography are rarely helpful.In children, the single most accurate diagnostic test for Meckel's diveicula is scintigraphy with sodium 99mTc-peechnetate. The 99mTc-peechnetate is preferentially taken up by the mucus-secreting cells of gastric mucosa and ectopic gastric tissue in the diveiculum. The diagnostic sensitivity of this scan has been repoed as high as 85%, with a specificity of 95% and an accuracy of 90% in the pediatric age group.In adults, however, the sensitivity of 99mTc-peechnetate scan falls to 63% because of the presence of less gastric mucosa in the diveiculum compared with that noted in the pediatric age group.Sabiston 20e pg:1310
