SpyGlass Cholangioscopy是什么?

SpyGlass cholangioscopy是最近开发的technique for the visualization of the bile ducts.

Cholangioscopy is a procedure in which a flexible tube, called an endoscope, allows the doctor to visualize the inside of the bile ducts. It is used to treat related medical conditions, such as removal of bile duct stones.

When coupled with the visualization of the pancreas, it’s called cholangiopancreatoscopy. Your doctor may choose to perform a cholangioscopy if other imaging techniques are insufficient to make an adequate diagnosis or therapeutic intervention is needed to direct visualization.

In addition to the visualization of the bile ducts, cholangioscopy will help your physician to visualize and examine the hepatic (liver) and pancreatic ducts.

SpyGlass cholangioscopy是最近开发的technique for the visualization of the bile ducts. It allows your doctor to see your biliary duct system and difficult-to-reach, small ducts in the pancreas, with a 6,000-pixel,fiber-optic probe attached to a tiny camera.

The procedure can be performed by a single doctor or endoscopist. Unlike the SpyGlass system, the previously used endoscopes were fragile and difficult to use. The newer versions of the SpyScope (the endoscope used in SpyGlass cholangioscopy) provide better and easier visualization.

Before the SpyGlass cholangioscopy, your doctor may:

• Order blood tests and imaging studies
• Ask you about any chronic health conditions
• Ask you about any medications you are on
• Ask about anyallergiesyou may have
• Explain the procedure in detail, including possible complications and address your doubts and concerns related to the procedure
• Obtain your written consent
• Ask you to not eat anything for at least eight to 12 hours before the procedure

During the cholangioscopy:

• You will be asked to wear a hospital gown.
• The anesthesiologist will give you a sedative and make your throat numb with a little local anesthetic.
• Your vital signs will be monitored during the procedure.
• A mouthpiece will be placed between yourteethto protect your mouth.
• You will not have any feeling of gagging or choking.
• The endoscope does not hinder or interfere with yourbreathing.

After the procedure:

• Your vital signs will be monitored in the recovery room.
• You will stay in the recovery room until you are weaned off the effect of the sedative.
• You may be asked to not eat anything until the next day.
• Because you will be under the effect ofsedatives, you will need someone to drive you home.

SpyGlass cholangioscopy may be done to diagnose and treat various conditions of the bile ducts, liver, and pancreas with the following:

• Biopsy of indeterminate strictures (abnormal narrowing of the ducts)
• Exclusion of a cancerous stricture
• Diagnosingcancersof the bile ducts
• Precise preoperative location of tumors within the bile or pancreatic ducts
• 诊断和评价post-transplantation biliary issues
• Evaluation of certain infections
• Hemobilia (bleeding from and/or into the biliary tract)

Treatment of cancers of the biliary or pancreatic ducts

Extraction or dissolution of biliary stones

Diagnosis ofchronic pancreatitis

Pancreatic stones extraction

Diagnosis of pancreatic duct tumors

Potential role in autoimmunepancreatitis

The complications of cholangioscopy are:

• Infections
• Abdominal pain
• Pancreatitis (inflammation of the pancreas)
• Hypotension(low blood pressure)
• Nausea/vomiting
• A liverabscess(collection of pus in the liver)
• Injury of the bile duct
• Nerve damage
• Elevated pancreatic enzymes (amylase and lipase) without clinical pancreatitis
• Inflammatory syndrome
