ABSTRACT
The study was aimed at defining the informative value of dynamic hepatobiliary scintigraphy (HBSG) in the evaluation of duodenal reflux in patients with postgastrectomic disorders after reconstructive surgery. HBSG was performed in 23 patients. After intravenous injection of 99mTc bromeside in a dose of 74-80 MBq, the areas concerned were identified in the projection of the liver, gallbladder, hepaticocholedochus, duodenum, and stomach for 120 minutes with 60-min cholagogic breakfast. Histrograms were plotted in the activity-time coordinates; hepatic function, gallbladder contractility, and hepaticocholedochal patency were evaluated; the duodenal motor function index and the gastroduodenal reflux were estimated. HBSG is physiological, which makes it possible to reveal duodenal motor-and-evacuation disorders, to specify the reason for poor outcomes of gastrectomy, to objectively evaluate the severity of postgastrectomic disorders, and to determine further treatment policy for this difficult group of patients.
