Design Retrospective medical record review with historical controls.. The drawn blood will be mixed with a radiopharmaceutical called Technetium-99m. Of the 2 cases who had laparotomies despite negative scans, aMeckel's diverticulum was foundin 1 andnocausefor thebleeding wasfound in the other. In 2 with positive pre-operative scans, a Meckel's diverticulum was found to be the cause of rectal bleeding. The sensitivity of exam is decreased, especially for an intermittent bleed due to background activity in the reticuloendothelial system and short imaging time (20 to 30 minutes). Purpose Optimal management of acute gastrointestinal (GI) bleeding requires accurate localization of the bleeding source. Despite intestinal barium, the 99m Tc-RBC scan demonstrated an active bleeding site in the small bowel in the left abdomen. Nuclear scans The threshold rate of GI bleeding for localization with radioisotope scanning is about 0.1 ml/min or more. Gallium salts like gallium citrate and gallium nitrate may be used.
