Abstract:
Meckel's diverticulum is one of the most common causes of lower gastrointestinal hemorrhage in the young. We report a case of a 16-year-old youth who presented with a 3-day history of bright red bleeding per rectum. Clinical examination revealed pallor but nothing else of note. The patient had a hemoglobin of 9 G% on admission. Tc-99m pertechnetate scintigraphy was performed and demonstrated an abnormal focus in the pelvis on the right that changed in position during the course of imaging. A laparotomy was done and a 5 x 2-cm Meckel's diverticulum was removed from the ileum. Histopathologic examination revealed heterotopic gastric mucosa of the body type. The patient recovered fully after operation.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
