Abstract:
:During a 2 year period, 83 patients with gastric motility problems were evaluated using radionuclide imaging. The patients presented with epigastric distress, postprandial fullness, pain, nausea, vomiting, and diarrhea; signs and symptoms suggestive of either gastroparesis or gastric outlet obstruction. Upper gastrointestinal series or endoscopy, or both, demonstrated no mechanical obstruction. After oral administration of a 300 g meal labeled with 600 muCi of technetium-99m sulfur colloid, a gastric emptying study consisting of serial images and data acquisition was performed. Of the patients studied, 52 had had peptic ulcer surgery, 17 were suspected of having gastroesophageal reflux, 8 were diabetic and suspected of having visceral enteropathy, and 6 had a history of irritable bowel syndrome. The normal mean gastric half emptying time was 77 +/- 16 minutes. Of the patients who had had gastric surgery, 90.4 percent had abnormal emptying: 69.2 percent had delayed gastric emptying and 21.2 percent had rapid gastric emptying time; 9.6 percent had normal emptying time. Of the gastroesophageal reflux group, all but two had normal gastric emptying time; 65 percent demonstrated gastroesophageal reflux within 15 minutes. Two of the patients with irritable bowel syndrome had prolonged emptying; the rest had normal emptying. All diabetic patients with gastroparesis had prolonged gastric emptying time, and all responded favorably to metoclopramide. Of the patients who previously had peptic ulcer surgery and had prolonged emptying time, 72 percent also responded favorably to metoclopramide. We conclude that radionuclide gastric imaging is a useful diagnostic test for the measurement of gastric emptying in patients with a variety of gastrointestinal motility disorders and may be helpful in assessing medical therapy and selecting those who may be candidates for surgery.
