Massive bleeding in an adult patient suffering from Meckel's diverticulum.

The case of a 22-year-old male who bled from a Meckel's diverticulum is described. The diagnosis was achieved after 99mTechnetium pertechnetate scintigraphy. With the administration of somatostatin very clear images were obtained. The histological examination confirmed the presence of ectopic gastric mucosa. The literature, over the last 10 years, has been reviewed to identify factors associated with bleeding in adults. Ectopic gastric mucosa is the most important factor predicting bleeding. The diagnostic approach to bleeding Meckel's diverticulum and the improvement in the quality of 99mTechnetium pertechnetate scintigraphy, following administration of somatostatin, is discussed.
