- There are several hepatic ducts that make left and right hepatic ducts. Right and left ducts together make the common hepatic duct. CHO joins cystic duct and they form common bile duct together. CBD originates in duodenum separately from pancreatic duct at minor papillae in cats.
- Biliary duct hyperplasia rate in cats is very low. The most common cause of biliary ducts dilation in cats is obstruction by sludges/lithes.
- A 1/5-year-old Persian cat presented with progressive jaundice and abdominal pain.
- 8 months later, after the first treatment and cholecystectomy, the patient presented with abdominal pain, good appetite, and progressive jaundice.
For the first time patient referred to radiology department to evaluate the liver, gallbladder, and biliary ducts.
Ultrasonography revealed inflammation of biliary tract toward duodenum and post-hepatic jaundice due to the sludges in gallbladder which obstructed the ducts.
The cholecystectomy, enterotomy and reopening the obstructed parts was performed.
The second time ultrasonography and CT-Scan angiography were performed to reevaluate liver, duodenum and remained ducts.
Severe extra hepatic dilation of biliary ducts in entrance region to duodenal papillae could be due to mechanical and/or functional obstruction.
Patient referred to surgeon. At the site of duodenum papillae and CBD opening, a hank-like mass of inflamed hepatic ducts was seen. The passage of bile to duodenum got opened again.
Because of the high risk of destroying the opening, sampling/biopsy was not performed.
The patient has been living so far, although the prognosis has been reported poor.
Cholecystectomy, enterotomy and reopening in addition to diet correction are very helpful.
