Dual-radionuclide simultaneous biliary and gastric scintigraphy to depict surgical treatment of bile reflux.

Biliary diversion procedures are performed during gastric surgery to decrease bile reflux. A 1-day dual-radionuclide examination was studied to determine its potential in the evaluation of the effectiveness of the Braun enteroenterostomy in reducing bile reflux and its effects on gastric emptying. Orally ingested gallium 67-labeled egg and intravenously administered technetium 99m diisopropyl-imino-diacetic acid were imaged simultaneously. This provided a way to depict both bile reflux and gastric emptying on the same day in patients who underwent gastric surgery. Overall, the Braun enteroenterostomy trades bile reflux, a symptomatic and premalignant disease, for gastroparesis, a less severe and often treatable disease. Copyright RSNA, 2003
