This man has a Meckel Diverticulum, which can cause hematochezia or melena. The 99mTc-pertechnetate scan used for diagnosis of Meckel Diverticula hinges on uptake of the radioactive compound by heterotopic gastric mucosa. FA 2019 p. 378.

The age of this patient threw me off. I would have thought that a Meckel Diverticulum would have presented earlier in life than 19 years old.
