[Operative procedure in choledochal cysts (author's transl)].

Case-description of a large cyst of the bile duct in a 10-year-old girl. The cyst extended from the distal part of the common hepatic duct almost to the duodenum. The pancreatic and bile ducts drained the cyst distally with a common outlet. The cyst was resected, except for a small preduodenal remnant. The remaining part was closed to form a hood, and implanted end-to-side into a loop of small bowel which had been diverted by Roux's method. The common hepatic duct was also anastomosed end-to-side with the same diverted loop of bowel.
