In a 31-year-old woman a congenital choledochal cyst that replaced the entire common bile duct was completely excised and the duct replaced by a gastric pedicle tube constructed from the greater curvature of the stomach and nourished by the right gastroepiploic vessels. The patient is completely well, 18 months after the operation. This gastric pedicle tube operation, done for the first time on a patient with a benign obstruction of the bile ducts, has the following advantages: (1) The greater curvature of the stomach is readily accessible and the duodenum need not be mobilized; (2) the gastric pedicle tube can be made any reasonable length and diameter by virtue of its excellent blood supply from the gastroepiploic vessels; and (3) bile passes through the duodenum, whereas in a choledochojejunostomy the duodenum is by-passed and peptic ulceration can result.
