| Popis: | A surgical model of a Meckel's diverticulum with ectopic gastric mucosa was constructed in seven dogs by implanting a full-thickness patch of gastric wall into the open end of a Roux-en-Y ileoileostomy. 99m Tc Pertechnetate scintiphotography with a gamma camera consistently identified this ectopic gastric mucosa when it was 1.8 sq cm or larger. Excision of the surgical models after 99m Tc injection showed that gastric mucosal radioactive counts were 6–20 times those in the adjacent ileum. Contact radioautographs of the specimens compared to the histologic sections from which they were made demonstrated that the 99m Tc was concentrated in the mucous cells of the gastric mucosal surgace and gastric pits. 99m Tc Scintiphotography should be utilized to identify ectopic gastric mucosa in symptomatic patients, recognizing that the amount of ectopic gastric mucosa present will be one determining factor in visualization. |
