Cholangiogram

SLIDE 1
Goals:
1. Relate the hepatoduodenal ligament and second portion of the duodenum to bony landmarks
2. Relate the pancreas to bony landmarks and the duodenum

SLIDE 2
– The gallbladder was removed
– To examine the integrity of the biliary system during surgery, a catheter was inserted in the ampulla of the duodenum.
Question 1. Besides the biliary tree, what other structure should be filed with contrast dye?
– the pancreatic duct, because it empties into the ampulla along with the bile duct.

SLIDE 3
Identify the following landmarks
– 12th rib
– L1 vertebrae
– L2 vertebrae
– catheter
– common bile duct and gallbladder
– pancreatic duct
– hepatoduodenal ligament
– 3rd portion of the duodenum (filled with contrast)
– infer the 2nd portion of the duodenum

SLIDE 4
SUMMARY
– The pancreatic and common bile ducts empty into the middle of the 2nd portion of the duodenum
– This portion of the duodenum is to the right of midline between L1 and L3; the 3rd portion crosses the midline at L3
– The body of the pancreas crosses the midline at L2
– The hepatoduodenal ligament begins near the midline near the L1/L2 disc (transpyloric plane) and angles towards the liver
