    Abstract:
    Combined endoscopic ultrasonography and duodenal bile drainage for microscopic bile examination was prospectively evaluated in patients with unexplained acute biliopancreatic disorders defined as follows: isolated biliary-type pain (group 1), biliary-type pain and elevated transaminases (group 2), or acute pancreatitis (group 3). All patients had prior negative transabdominal ultrasonography. Endoscopic ultrasonography and bile drainage were combined under anesthesia during the same procedure. Combined endoscopic ultrasonography and bile drainage was feasible without any complication in the 48 patients studied. Biliary lithiasis was diagnosed in 20 patients (42%), 5 in group 1 (38%), 7 in group 2 (39%), and 8 in group 3 (47%). Endoscopic ultrasonography and microscopic bile examination were positive respectively in 17 (36%) and in 13 (27%) patients. In conclusion, combined endoscopic ultrasonography and bile drainage for microscopic bile examination is a simple procedure. Biliary lithiasis is diagnosed in a high proportion of patients with unexplained acute biliopancreatic disorders.
