Preoperative diagnosis of Meckel's diverticulum with 99mTc-pertechnetate.
99mTc-pertechnetate scintigraphy of the digestive tract was performed on 4 children with intestinal bleeding. Two of them showed a focal uptake in the right lower abdominal quadrant and a diagnosis of bleeding Meckel's diverticulum was confirmed by surgery. This procedure being easy to perform, non-invasive and remunerative, should be systematically applied in paediatric intestinal bleeding.
