Intraductal Ultrasonography as a Local Assessment Before Magnetic Compression Anastomosis for Obstructed Choledochojejunostomy


Figure 1.
Figure 1. Percutaneous transhepatic cholangiography showed complete obstruction of choledochojejunostomy. The obstructive distance was 7 mm, as measured by cholangiography and fluoroscopy.
Figure 2.
Figure 2. Intraductal ultrasonography through the percutaneous transhepatic cholangiographic drainage tube revealed a fibrous heterogeneous hyperechoic appearance without fluid collection, vessels or foreign bodies between the common bile duct and jejunum (arrow).
Figure 3.
Figure 3. The two magnets were attracted towards each other transmurally and compressed the obstruction site from both sides.
Figure 4.
Figure 4. After reanastomosis was confirmed, the magnets were retrieved endoscopically.
Figure 5.
Figure 5. A 16-Fr indwelling drainage tube was placed in the juodenum through percutaneous transhepatic cholangiographic drainage tube.
