Biliary Microlithiasis
Biliary microlithiasis refers to the creation of small gallstones less than 3 mm in diameter in the biliary duct or gallbladder. It has been suggested as a cause of postcholecystectomy syndrome, or PCS, the symptoms of which include: * Upset stomach, nausea, and vomiting. * Gas, bloating, and diarrhea. * Persistent pain in the upper right abdomen. Diagnostics * Biliary Microlithiasis may be detectable by ultrasound using a Rapid Patient Rotation Ultrasound Protocol * Analysis of biliary sludge obtained through endoscopic retrograde cholangiopancreatography (ERCP) Treatment * Oral ursodeoxycholic acid can be used to dissolve these crystals.

Biliary Duct
A bile duct is any of a number of long tube-like structures that carry bile, and is present in most vertebrates. Bile is required for the digestion of food and is secreted by the liver into passages that carry bile toward the hepatic duct. It joins the cystic duct (carrying bile to and from the gallbladder) to form the common bile duct which then opens into the intestine. Structure The top half of the common bile duct is associated with the liver, while the bottom half of the common bile duct is associated with the pancreas, through which it passes on its way to the intestine. It opens into the part of the intestine called the duodenum via the ampulla of Vater. Segments The biliary tree (see below) is the whole network of various sized ducts branching through the liver. The path is as follows: Bile canaliculi → Canals of Hering → interlobular bile ducts → intrahepatic bile ducts → left and right hepatic ducts ''merge to form'' → common hepatic duct ''exits liver ...

Gallbladder
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. The gallbladder can be affected by gallstones, formed by material that cannot be dissolved – usually cholesterol or bilirubin, a product of haemoglobin breakdown. These may cause significant pain, particularly in the upper-right corner of the abdomen, and are often treated with removal of the gallbladder (called a cholecystectomy). Cholecystitis, inflammation of the gallbladder, has a wide range of causes, including result from the impaction of gallstone ...

Postcholecystectomy Syndrome
Postcholecystectomy syndrome (PCS) describes the presence of abdominal symptoms after a cholecystectomy (gallbladder removal). Symptoms occur in about 5 to 40 percent of patients who undergo cholecystectomy, and can be transient, persistent or lifelong. The chronic condition is diagnosed in approximately 10% of postcholecystectomy cases. The pain associated with postcholecystectomy syndrome is usually ascribed to either sphincter of Oddi dysfunction or to post-surgical adhesions. A recent 2008 study shows that postcholecystectomy syndrome can be caused by biliary microlithiasis. Approximately 50% of cases are due to biliary causes such as remaining stone, biliary injury, dysmotility and choledococyst. The remaining 50% are due to non-biliary causes. This is because upper abdominal pain and gallstones are both common but are not always related. Non-biliary causes of PCS may be caused by a functional gastrointestinal disorder, such as functional dyspepsia. Chronic diarrhea in po ...

Endoscopic Retrograde Cholangiopancreatography
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. ERCP is used primarily to diagnose and treat conditions of the bile ducts and main pancreatic duct, including gallstones, inflammatory strictures (scars), leaks (from trauma and surgery), and cancer. ERCP can be performed for diagnostic and therapeutic reasons, although the development of safer and relatively non-invasive investigations such as magnetic resonance cholangiopancreatography (MRCP) and endoscopic ultrasound has meant that ERCP is now rarely performed without therapeutic intent.

Ursodeoxycholic Acid
Ursodeoxycholic acid (UDCA), also known as ursodiol, is a secondary bile acid, produced in humans and most other species from metabolism by intestinal bacteria. It is synthesized in the liver in some species, and was first identified in bile of bears of genus ''Ursus'', from which its name derived. In purified form, it has been used to treat or prevent several diseases of the liver or bile ducts. It is available as a generic medication. Medical uses UDCA has been used as medical therapy in gallstone disease (cholelithiasis) and for biliary sludge. UDCA helps reduce the cholesterol saturation of bile and leads to gradual dissolution of cholesterol-rich gallstones. UDCA may be given after bariatric surgery to prevent cholelithiasis, which commonly occurs due to the rapid weight loss producing biliary cholesterol oversaturation and also biliary dyskinesia secondary hormonal changes. Primary biliary cholangitis UDCA is used as therapy in primary biliary cholangitis (PBC; previ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Medical Terminology
Medical terminology is a language used to precisely describe the human body including all its components, processes, conditions affecting it, and procedures performed upon it. Medical terminology is used in the field of medicine Medical terminology has quite regular morphology, the same prefixes and suffixes are used to add meanings to different roots. The root of a term often refers to an organ, tissue, or condition. For example, in the disorder known as hypertension, the prefix "hyper-" means "high" or "over", and the root word "tension" refers to pressure, so the word "hypertension" refers to abnormally high blood pressure. The roots, prefixes and suffixes are often derived from Greek or Latin, and often quite dissimilar from their English-language variants. This regular morphology means that once a reasonable number of morphemes are learnt it becomes easy to understand very precise terms assembled from these morphemes. Much medical language is anatomical terminology, con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
