Oral cholecystography in the early phase of acute alcoholic pancreatitis a prospective, randomized comparison of telepaque® and bilopaque®

Biliary tract disease is a major cause of acute pancreatitis. However, with traditionally employed Telepaque®, radio- graphic visualization of the gallbladder during acute pancreatitis remains unreliable, even in patients with apparently normal gallbladders. Therefore, oral cholecystography has customarily been deferred for such patients for several weeks. Recently, successful oral cholecystography has been described during the acute episode of pancreatitis, using Bilopaque®, a more water-soluble cholecystopaque. The relative intestinal absorption of Telepaque and Bilopaque and the ability of these agents to produce diagnostic oral cholecystograms of fasting patients with acute alcoholic pancreatitis were compared. Forty-five hospitalized patients were studied within 96 hours of admission. Mean peak plasma contrast concentrations for Bilopaque exceeded those for Telepaque. Thirty-one percent of the Bilopaque group achieved diagnostic single-dose oral cholecystograms, compared with to 11% of the Telepaque group (P < 0.05).
