Comparison of Gastric Aspiration and HIDA Scintigraphy in Detecting Fasting Duodenogastric Bile Reflux

Abstract

Gastric aspiration and HIDA scintigraphy have been compared to assess duodenogastric bile reflux. Gastric aspiration was performed on two separate occasions with a total examination time of 3 h. The highest 1-h output and the highest concentration of bile acids were recorded. HIDA scintigraphy was carried out for 90 min after an injection of 60 MBq 99mTc-dimethyl-iminodiacetic acid (HIDA). Forty-six patients with different gastrointestinal disorders were studied; 24 patients were positive and 13 negative in both tests. Accordingly, the methods agreed in 37 to 46 patients (80.4%). It is concluded that gastric aspiration is as reliable as HIDA scintigraphy to assess fasting bile reflux.
