The authors studied 11 asymptomatic post‐cholecys‐tectomy female volunteers by endoscopic retrograde cholangiography and measured contrast drainage time from the hiliary tree at 5‐min intervals for 1 h. The age range was 24‐64 yr, and time since cholecystectomy ranged from 1 to 36 yr. The common hile duct diameter averaged 8.3 mm (6‐16 mm). Meglumine diatrizoate (Hypaque) 50% was the contrast media. Patients received only diazepam anesthesia (meperidine and glu‐cagon avoided), and drainage times were measured in the prone position in 11 patients. Three subjects with abnormal drainage were reevaluated in the supine position; two of three studies normalized. Two subjects required hospitalization for uncomplicated post‐procedure pancreatitis. Greater than 25% of the dye remained in the biliary tree at 45 min in 63% of volunteers, whereas more than 50% contrast media remained in two of the volunteers. The authors conclude that delayed drainage of contrast media is common in asymptomatic post‐cholecystectomy volunteers.
