[Giant duodenal diverticula with heterotopic gastric mucosa. Its demonstration with technetium 99].

The duodenal diverticulum, except for occasional findings, are diagnosed by their complications, these are found in 10% of the cases and they are: 1) diverticulitis 2) haemorrhage 3) mechanic disturbances 4) perforation 5) obstruction 6) malabsorption syndrome. The case that motivated our communication appeared as a massive haemorrhage, that was medically treated considering the high mortality, rate of the surgical procedures. As the duodenal diverticuli can be cause of acute or chronic digestive haemorrhage, and this is frequently due to the erosion produced, by the heterotopic gastric mucosae, we consider that its demonstration with technetium 99 can be a valuable diagnostic method, as has already been demonstrated in other pathologies that present heterotopic mucosae, and as has been demonstrated in our case.
