title: Technical note: oral water and intravenous glucagon--to aid ultrasonic visualization of the common bile duct.
abstract: Gas in the stomach, duodenum and hepatic flexure frequently prevents ultrasonic visualization of the distal common bile duct. By filling the stomach and duodenum with water, enhanced by temporary paralysis with glucagon, the gas is displaced and improved visualization of the distal common bile duct is obtained.
