Retained-antrum syndrome is a rare condition, occurring in Billroth II gastrectomised patients, in which an ulcer recurs associated with high levels of circulating gastrin. Some gastrin tests are useful to differentiate a retained antrum from a gastrinoma, but a firm diagnosis is sometimes very difficult. We have studied two cases of retained-antrum syndrome both by gastrin tests and by [99mTc] pertechnetate scintiphotography. By this method a prominent area of activity was observed on the anatomic site of the duodenal stump bottom. It appeared after 20 or 30 min and lasted for the 2 hr of observation. After surgical resection, no area of activity was observed at the scintiphotographic followup. No false positive was observed out of the more than 30 subjects studied. Scintiphotography by pertechnetate seems able to demonstrate the presence and the size of retained gastric antrum in B II gastrectomised patients with recurrent ulcer.
