[Preoperative detection of a bleeding Meckel's diverticulum by 99mTc-pertechnetate scinitigraphy (author's transl)].

A Meckel's diverticulum containing gastric mucosa was causing recurrent intestinal bleeding in a 5-year old boy. 99mTc-pertechnetate scintigraphy was used to demonstrate the heterotopic gastric mucosa preoperatively. Compared to intestinal radiography and angiography, 99mTc-pertechnetate scintigraphy is a mild and uncomplicated investigation without any risk and with a minimum of radiation exposure. Evaluating its results critically this procedure can be of great help in the preoperative diagnosis of intestinal bleedings of unknown origin.
