Figure 17a.  Stricture resulting from hepaticojejunostomy in a 33-year-old woman with jaundice. The patient had undergone hepaticojejunostomy because of a bile duct injury sustained during laparoscopic cholecystectomy. (a) MR cholangiogram shows castlike filling defects (arrows) representative of stones in the dilated bile ducts immediately above the strictured hepaticojejunostomy. A small amount of fluid in the jejunum (arrowhead) demarcates the hepaticojejunostomy. (b) Percutaneous transhepatic cholangiogram demonstrates the intraductal stones (arrows), dilated ducts, and anastomotic stricture (arrowhead).
