Two false-negative results using morphine sulfate in hepatobiliary imaging.
Morphine sulfate has been used in hepatobiliary imaging to cause contraction of the sphincter of Oddi, thereby increasing pressure in the biliary tree. If the cystic duct is patent, the increased pressure usually causes bile to flow into the cystic duct with filling of the gallbladder. Using this technique, the authors have encountered two false-negative cases. Both patients received 0.04 mg/kg of morphine sulfate intravenously, 40 minutes after the intravenous administration of 5 mCi of technetium 99m-DISIDA. Although both patients filled their gallbladders within 1 hour, they both underwent surgical exploration because of high clinical suspicion of acute cholecystitis. Both were found to have acute cholecystitis.
