Sodium pertechnetate Tc 99m antral scan in the diagnosis of retained gastric antrum. 1984

C H Lee, and F K P'eng, and P H Yeh

Retained gastric antrum (RGA) is a major factor in recurrent peptic ulcer. We studied 121 patients with proven anastomotic ulcers following subtotal gastrectomy and Billroth II reconstruction with sodium pertechnetate Tc 99m to determine the presence of RGA. Of the patients, 59 required surgery, 22 had RGA, and 16 had a positive scan for RGA. This noninvasive examination has 100% specificity. If RGA is identified before operation, minimal time is wasted in exploration of the abdomen, which is especially important in dealing with emergency cases. When an antral scan is negative for RGA, the surgeon is still advised to search for this condition.

UI	MeSH Term	Description	Entries
D010437	Peptic Ulcer	Ulcer that occurs in the regions of the GASTROINTESTINAL TRACT which come into contact with GASTRIC JUICE containing PEPSIN and GASTRIC ACID. It occurs when there are defects in the MUCOSA barrier. The common forms of peptic ulcers are associated with HELICOBACTER PYLORI and the consumption of nonsteroidal anti-inflammatory drugs (NSAIDS).

D011706	Pyloric Antrum	The region between the sharp indentation at the lower third of the STOMACH (incisura angularis) and the junction of the PYLORUS with the DUODENUM. Pyloric antral glands contain mucus-secreting cells and gastrin-secreting endocrine cells (G CELLS).

D011877	Radionuclide Imaging	The production of an image obtained by cameras that detect the radioactive emissions of an injected radionuclide as it has distributed differentially throughout tissues in the body. The image obtained from a moving detector is called a scan, while the image obtained from a stationary camera device is called a scintiphotograph.

D015043	Zollinger-Ellison Syndrome	A syndrome that is characterized by the triad of severe PEPTIC ULCER, hypersecretion of GASTRIC ACID, and GASTRIN-producing tumors of the PANCREAS or other tissue (GASTRINOMA). This syndrome may be sporadic or be associated with MULTIPLE ENDOCRINE NEOPLASIA TYPE 1.	Syndrome, Zollinger-Ellison,Zollinger Ellison Syndrome
