ABSTRACT

Introduction: gastroparesis is defined as a delay in gastric emptying in the absence of mechanical obstruction, associated with symptoms such as nausea and/or vomiting, postprandial gastric fullness feeling, early satiety or epigastric pain for more than 3 months. Diabetes mellitus and idiopathic are the most frequent causes related. The gold standard in the diagnosis of delayed gastric emptying is gammagraphy and 99mTc-sulfur colloid is the most widely used radiopharmaceutical.
Objective: assess gastric emptying and show the results obtained with the use of colloidal tin in the gammagraphy study of gastric emptying.
Methods: a descriptive study was conducted in 64 patients older than 18 years using 99mTc-sulfur colloid radiopharmaceutical.
Results: 31 % of patients had symptoms. The emptying time was normal in 44 cases and the association of gastroparesis symptoms was observed in 20 (15 diabetics and 5nondiabetics), 9 patients had delayed emptying, but they did not report symptoms. Gastroparesis was more frequent in women than in men (35% versus 21%). 21% of patients had moderate delayed gastric emptying.
Conclusions: results obtained with colloidal Tc-Sn 99m are comparable with those reported by other authors using 99mTc-SC in gammagraphy assessment of gastric emptying.
