Intravenous cholangiography is a form of cholangiography that was introduced in 1954.^[1]

Overview

The intravenous cholangiogram or IVC is a radiologic (x-ray) procedure that is used primarily to look at the larger bile ducts within the liver and the bile ducts outside the liver. The procedure can be used to locate gallstones within these bile ducts. IVC also can be used to identify other causes of obstruction to the flow of bile, for example, narrowings (strictures) of the bile ducts and cancers that may impair the normal flow of bile.

Procedure

To do an IVC, an iodine-containing dye (meglumine ioglycamate) is injected intravenously into the blood. The liver then removes the dye from the blood and excretes it into the bile. The iodine is sufficiently concentrated as it is secreted into the bile that it does not need to be further concentrated by the gallbladder to outline the bile ducts and any gallstones that may be there. The gallbladder is not always seen on an IVC, as the iodine-containing bile may bypass the gallbladder entirely and empty directly into the small intestine.

Risks

Occasional serious allergic reactions can occur to any iodine-containing dye. These reactions can usually be treated and rarely result in death.

Indications

The IVC is not used as much today as it was. Its use always was limited, because it did not work when there was more than a minimal amount of jaundice, and many of the conditions it was used to detect also caused substantial jaundice. The IVC has been largely replaced by other diagnostic procedures—by ERCP (endoscopic retrograde cholangiopancreatography), endoscopic ultrasound and, increasingly, by MRI cholangiography, none of which are affected by jaundice. It is sometimes used when ERCP is unsuccessful.^[2]

In vertebrates, the gallbladder, also known as the cholecyst, is a small hollow organ where bile is stored and concentrated before it is released into the small intestine. In humans, the pear-shaped gallbladder lies beneath the liver, although the structure and position of the gallbladder can vary significantly among animal species. It receives and stores bile, produced by the liver, via the common hepatic duct, and releases it via the common bile duct into the duodenum, where the bile helps in the digestion of fats.

A bile duct is any of a number of long tube-like structures that carry bile, and is present in most vertebrates.

Gallstone Disease where stones form in the gallbladder

A gallstone is a stone formed within the gallbladder out of precipitated bile components. The term cholelithiasis may refer to the presence of gallstones or to any disease caused by gallstones, and choledocholithiasis refers to presence of migrated gallstones within bile ducts.

Cholecystitis is inflammation of the gallbladder. Symptoms include right upper abdominal pain, pain in the right shoulder, nausea, vomiting, and occasionally fever. Often gallbladder attacks precede acute cholecystitis. The pain lasts longer in cholecystitis than in a typical gallbladder attack. Without appropriate treatment, recurrent episodes of cholecystitis are common. Complications of acute cholecystitis include gallstone pancreatitis, common bile duct stones, or inflammation of the common bile duct.

Cholecystectomy is the surgical removal of the gallbladder. Cholecystectomy is a common treatment of symptomatic gallstones and other gallbladder conditions. In 2011, cholecystectomy was the eighth most common operating room procedure performed in hospitals in the United States. Cholecystectomy can be performed either laparoscopically, or via an open surgical technique.

Endoscopic retrograde cholangiopancreatography (ERCP) is a technique that combines the use of endoscopy and fluoroscopy to diagnose and treat certain problems of the biliary or pancreatic ductal systems. It is primarily performed by highly skilled and specialty trained gastroenterologists. Through the endoscope, the physician can see the inside of the stomach and duodenum, and inject a contrast medium into the ducts in the biliary tree and pancreas so they can be seen on radiographs.

The common bile duct, sometimes abbreviated as CBD, is a duct in the gastrointestinal tract of organisms that have a gallbladder. It is formed by the confluence of the common hepatic duct and cystic duct and terminates by uniting with pancreatic duct, forming the ampulla of Vater. The flow of bile from the ampulla of Vater into the duodenum is under the control of the sphincter of Oddi.

Primary sclerosing cholangitis Medical condition

Primary sclerosing cholangitis (PSC) is a long-term progressive disease of the liver and gallbladder characterized by inflammation and scarring of the bile ducts, which normally allow bile to drain from the gallbladder. Affected individuals may have no symptoms or may experience signs and symptoms of liver disease, such as yellow discoloration of the skin and eyes, itching, and abdominal pain.

Cholangiography is the imaging of the bile duct by x-rays and an injection of contrast medium.

Mirizzi's syndrome is a rare complication in which a gallstone becomes impacted in the cystic duct or neck of the gallbladder causing compression of the common hepatic duct, resulting in obstruction and jaundice. The obstructive jaundice can be caused by direct extrinsic compression by the stone or from fibrosis caused by chronic cholecystitis (inflammation). A cholecystocholedochal fistula can occur.

Common bile duct stone, also known as choledocholithiasis, is the presence of gallstones in the common bile duct (CBD). This condition can cause jaundice and liver cell damage. Treatment is by choledocholithotomy and endoscopic retrograde cholangiopancreatography (ERCP).

Magnetic resonance cholangiopancreatography (MRCP) is a medical imaging technique. It uses magnetic resonance imaging to visualize the biliary and pancreatic ducts non-invasively. This procedure can be used to determine whether gallstones are lodged in any of the ducts surrounding the gallbladder.

Endoscopic ultrasound (EUS) or echo-endoscopy is a medical procedure in which endoscopy is combined with ultrasound to obtain images of the internal organs in the chest, abdomen and colon. It can be used to visualize the walls of these organs, or to look at adjacent structures. Combined with Doppler imaging, nearby blood vessels can also be evaluated.

Ascending cholangitis, also known as acute cholangitis or simply cholangitis, is inflammation of the bile duct (cholangitis), usually caused by bacteria ascending from its junction with the duodenum. It tends to occur if the bile duct is already partially obstructed by gallstones.

Biliary colic Medical condition in which gallstones cause acute pain

Biliary colic, also known as symptomatic cholelithiasis, a gallbladder attack or gallstone attack, is when a colic occurs due to a gallstone temporarily blocking the cystic duct. Typically, the pain is in the right upper part of the abdomen, and can be severe. Pain usually lasts from 15 minutes to a few hours. Often, it occurs after eating a heavy meal, or during the night. Repeated attacks are common.

Gallbladder diseases are diseases involving the gallbladder and is closely linked to biliary disease, with the most common cause being gallstones (cholelithiasis).

Percutaneous transhepatic cholangiography, percutaneous hepatic cholangiogram, or percutaneous transhepatic cholangiography and drainage is a radiological technique used to visualize the anatomy of the biliary tract. A contrast medium is injected into a bile duct in the liver, after which X-rays are taken. It allows access to the biliary tree in cases where endoscopic retrograde cholangiopancreatography has been unsuccessful. Initially reported in 1937, the procedure became popular in 1952.

Sphincter of Oddi dysfunction Medical condition

Sphincter of Oddi dysfunction refers to a group of functional disorders leading to abdominal pain due to dysfunction of the Sphincter of Oddi: functional biliary sphincter of Oddi and functional pancreatic sphincter of Oddi disorder. The sphincter of Oddi is a sphincter muscle, a circular band of muscle at the bottom of the biliary tree which controls the flow of pancreatic juices and bile into the second part of the duodenum. The pathogenesis of this condition is recognized to encompass stenosis or dyskinesia of the sphincter of Oddi ; consequently the terms biliary dyskinesia, papillary stenosis, and postcholecystectomy syndrome have all been used to describe this condition. Both stenosis and dyskinesia can obstruct flow through the sphincter of Oddi and can therefore cause retention of bile in the biliary tree and pancreatic juice in the pancreatic duct.

Choledochoduodenostomy (CDD) is a surgical procedure to create an anastomosis, a surgical connection, between the common bile duct (CBD) and an alternative portion of the duodenum. In healthy individuals, the CBD meets the pancreatic duct at the ampulla of Vater, which drains via the major duodenal papilla to the second part of duodenum. In cases of benign conditions such as narrowing of the distal CBD or recurrent CBD stones, performing a CDD provides the diseased patient with CBD drainage and decompression. A side-to-side anastomosis is usually performed.

Biliary endoscopic sphincterotomy is a procedure where the sphincter of Oddi and the segment of the common bile duct where it enters the duodenum are cannulated and then cut with a sphincterotome, a device that includes a wire which cuts with an electric current (electrocautery).
