Bleeding Meckel's diverticulum diagnosed with enterocolysis and mesenteric angiography

Due to the decreasing incidence of heterotopic gastric mucosa and increasing incidence of other causes of gastrointestinal haemorrhage in the adult population, sensitivity and specificity decrease to 63% and 2% respectively.1 Tc-99m labelled red blood cell scintigraphy is less accurate for the specific diagnosis of Meckel's diverticulum, but can localise gastrointestinal haemorrhage if bleeding is brisk enough (in the range 0.1 mL/min).
