What is a Choledochocele?
A choledochocele is a cystic dilation of the distal common bile duct (CBD). It corresponds to a type 3 choledochal cyst in the classification by Todani et al1 and is extremely rare.
Which of the following is the most accurate imaging study for diagnosis and classification of choledochal cyst?
CT scanning is highly accurate and offers a great deal of information that is helpful not only in confirming the diagnosis, but also in planning surgical approaches. Computed tomography scan demonstrates a choledochal cyst involving the intrahepatic portion of the common hepatic duct and the main left hepatic duct.
What is Type 4 choledochal cyst?
Background/purpose: Type IV-A choledochal cysts are characterized by congenital cystic dilatation of the biliary tree extending to involve the intrahepatic biliary channels also. A single-center experience of the management of type IV-A choledochal cysts is presented.
What causes bile duct cysts?
Bile Duct Cysts The most widely accepted hypothesis is that cystic dilatation is related to an anomalous arrangement of the pancreaticobiliary junction, with a long common channel that allows reflux of pancreatic juice into the biliary tree causing inflammation, ectasia, and ultimately dilatation [9].
Is a HIDA scan like an MRI?
a HIDA scan (uses radioactive material) can measure gallbladder emptying while an ERCP test uses an endoscope to place dye in the ducts of the pancreas, gallbladder and liver, and. Magnetic resonance imaging (MRI) is sometimes used to detail the organ structures (liver, gallbladder, and pancreas).
What does positive HIDA scan mean?
A HIDA scan might help in the diagnosis of several diseases and conditions, such as: Gallbladder inflammation (cholecystitis) Bile duct obstruction. Congenital abnormalities in the bile ducts, such as biliary atresia. Postoperative complications, such as bile leaks and fistulas.
Why ERCP is done?
You may need ERCP to find the cause of unexplained abdominal pain or yellowing of the skin and eyes (jaundice). It may be used to get more information if you have pancreatitis or cancer of the liver, pancreas, or bile ducts. Other things that may be found with ERCP include: Blockages or stones in the bile ducts.
Is ERCP considered surgery?
Scott Sundick, MD, is board-certified in general surgery and vascular surgery. Since 2012, he has practiced with The Cardiovascular Care Group in New Jersey. Endoscopic retrograde cholangiopancreatography (ERCP) is an invasive procedure used for the diagnosis and treatment of obstruction in the biliary system.
How do they remove a cyst from the bile duct?
Complete resection of cysts and Roux-en-Y hepaticojejunostomy (RYHJ) is the procedure of choice for type I and IVb bile duct cysts. The success rate of this approach has been reported as 92%[35]. If adequate, the procedure may be performed laparoscopically.
Is the choledochal cyst on MRI different from the ultrasound?
In their case, the MRI image of the choledochal cyst was presented as a simple intra-abdominal cyst that was not different from that obtained by prenatal ultrasound.
How accurate is magnetic resonance cholangiopancreatography (MRCP) in diagnosing choledochal cysts?
The reported diagnostic accuracy of magnetic resonance cholangiopancreatography (MRCP) in choledochal cysts in this series was 100%.
Which imaging modalities are used to diagnose type V choledochal cysts (Caroli disease)?
Type V choledochal cyst (Caroli disease). A number of imaging modalities can be used to detect a choledochal cyst, such as ultrasonography, CT, MR cholangiopancreatography (MRCP), endoscopic retrograde cholangiopancreatography, and percutaneous transhepatic cholangiography. [ 1]
What is the pathophysiology of choledochal cysts?
Choledochal cysts are congenital anomalies of the bile ducts. They consist of cystic dilatations of the extrahepatic biliary tree, intrahepatic biliary radicles, or both. [ 1, 2] Alonso-Lej et al provided the first systematic description of choledochal cysts, based on the clinical and anatomic findings in 96 cases. [ 3]
