Gallbladder Conditions

Gallstones: Most common location of gallstones is definitely gallbladder, but gallstones often lodge inside different areas of biliary ducts and may also block flow of bile this causes obstructive jaundice.

Other Causes of Biliary Pain. The sudden obstruction of the bile ducts causes biliary colic. Other processes that suddenly obstruct the ducts also can cause biliary colic, for example, bleeding into the ducts or the entry of parasites into the ducts, but these causes are rare. The occurrence of slowly progressive obstruction does not cause biliary colic unless sudden obstruction is superimposed upon the progressive obstruction.

Gallbladder and biliary tree (anatomy, gallstones)

For this reason, it is uncommon for slowly growing cancers of the bile ducts, gallbladder, or pancreas through which the common bile duct passes to cause biliary colic. Diagnosis of gallstones as cause of biliary pain In addition to ultrasonography, it may be useful to obtain blood tests to assess the liver function aminotransferases and pancreas amylase.

If the tests are abnormal they support the diagnosis of a process involving the liver, bile ducts and gallbladder, or pancreas. They do not indicate specifically what the problem is, but an early rise and rapid fall in their levels suggests obstruction of the biliary ducts. Endoscopic ultrasonography is the best test for diagnosing gallstones, but it is expensive and carries the risk of complications. Whenever biliary colic is suspected, the possibility of heart pain angina or heart attack , due to ischemia [reduced blood flow of the heart] should also be considered and vice-versa.

Heart pain and biliary pain, although caused by two very different processes, share some common characteristics. They may be confused with one another because sometimes heart pain can be felt in the mid-upper abdomen, and sometimes biliary colic can be felt in the chest. Heart pain also may be associated with nausea and vomiting. Gallbladder Pain Symptoms and Signs. The most common symptom that accompanies biliary colic is nausea with or without vomiting. The vomiting does not make the pain better since it has no effect on the distended ducts or gallbladder.

Other non-specific symptoms, more likely caused as a response to pain rather than the obstruction, are:. Symptoms that suggest other causes for pain are pain that is maximal in the lower abdomen, abdominal bloating or belching, and abnormal bowel patterns.

Cholecystitis may occur as a complication of prolonged obstruction of the ducts. It occurs when inflammation develops, usually as a result of bacterial infection. If it results as a complication of sudden obstruction of the ducts, it may begin as biliary colic. During week four of development, differentiation of embryonic endoderm gives rise to an outpouching of the distal region of the foregut. This structure, known as the hepatic diverticulum , gives rise to the gallbladder and associated biliary duct; as well as the liver.

Recall that around this time there is extensive cardiac origami and as such, it is necessary that cells of the developing heart and digestive system be separated. Therefore, an organized layer of splanchnic mesoderm known as the septum transversum grows between the heart and the midgut. As the hepatic diverticulum grows, it divides unequally. The larger cranial bud, commits to becoming the liver primordium and the extrahepatic biliary tree.


The extrahepatic biliary system discussed below is identifiable by the 5th week of gestation. The extrahepatic bile ducts extend into the mesenchyme of the septum transversum and gives rise to the characteristic fibrous appearance of the liver. Within the liver, the endometrial cells that overlap each other to form the hepatocytes also give rise to the intrahepatic biliary system.

Communication with the extrahepatic bile ducts marks the completion of the intrahepatic biliary system, which occurs around the 10th gestational week.

The smaller caudal bud of the hepatic diverticulum further subdivides into superior and inferior buds. The superior bud and its associated stalk will become the gallbladder and cystic duct respectively , while the inferior bud becomes the ventral component of the pancreas. Both the liver and gallbladder will grow into the ventral mesogastrium formed from the septum transversum. The gallbladder, cystic duct, and extrahepatic bile ducts are initially occluded with cells.

As the bile duct continues to grow, the centrally located cells undergo apoptosis ; thus converting the solid tube into a luminal structure. Initially, this process starts within the common bile duct and continues distally at the end of the 5th gestational week.

Recanalization is a slow process that overlaps with an anatomical change in the position of the common bile duct and ventral pancreas; such that the common bile duct is situated on the dorsomedial surface of the duodenum. The bile duct only becomes patent between the end of the second and beginning of the 8th gestational weeks as it continues into the duodenum. Proximally, in the 7th gestational week, recanalization progresses into the cystic duct and extends into the gallbladder by the 12th gestational week.

Neonates have a small peritoneal surface and as a result, the fundus lies within the liver margin. After the second year of life, gall bladder assumes the relative size.

The common hepatic duct and pancreatic ducts unite to form the hepatopancreatic duct. It extends into the duodenal wall at the level of the submucosa as the ampulla of Vater major duodenal papilla. Concentric mesenchymal rings surround the ampulla and give rise to the sphincter of Oddi. The sphincter of Oddi further differentiates around the 10th gestational week into the sphincter choledochus superior and inferior; both of which surround the bile duct.

Although final development of the ampulla continues to the 28th gestational week, the extrahepatic is ready to transport bile from the liver to the duodenum by week 12 of gestation i. The gallbladder is essentially a pear-shaped cul-de-sac that communicates with the common hepatic ducts via the cystic duct.

In vivo, the sac is actually grey-blue in appearance and not green as depicted in the texts. The 7. There are instances where the gallbladder may be completely buried within the liver parenchyma; here it is said to have an intraparenchymal pattern. In other cases, the gallbladder may have its own mesentery arising from the visceral and parietal peritoneum; in which case it is described as having a mesenteric pattern. These are two extremes of a spectrum on which the gallbladder may appear.

The sac can accommodate 25 — 30 mL of bile under normal circumstances; but can expand up to 50 mL. There are three anatomical parts of the gallbladder. From lateral to medial, these are the fundus, body and neck infundibulum. The fundus is the most lateral part of the gallbladder. It typically protrudes beyond the lower border of the liver and may touch the anterior abdominal wall. A clinical landmark for the fundus of the gallbladder is at the level of the 9th costal , at the intersection of the lateral border of the right rectus abdominis and the costal margin.

An enlarged gallbladder can be appreciated clinically at this point. Medial to the fundus is the body of the gallbladder. This is the portion of the sac that is either embedded in, or in contact with the gallbladder fossa of the liver. The pars descendens second part of the duodenum , as well as the hepatic flexure and proximal transverse colon , are posteriorly related to the gallbladder.

The body of the gallbladder tapers off medially into the neck or infundibulum. It is proximal to the porta hepatis and is generally associated with a short mesentery that also contains the cystic artery. As the neck narrows into the cystic duct , it contains slanted grooves that progresses into the spiral valve of the cystic duct. It is an outpouching of the wall of the neck as a result of stones in the gallbladder or dilatation of the sac.

There size of the pouch may vary among patients, and can be associated with numerous complications. Gallbladder inside a cadaver: The gallbladder is located inside the gallbladder fossa on the inferior aspect of the liver. It looks dehydrated and shrivelled in cadavers because this cavitary organ has no biliary contents to keep it expanded, like in living human beings. In addition, the cystic artery supplying the gallbladder looks green from the presence of bile. It is also very fragile, making dissection especially difficult. This image also depicts a horseshoe kidney.

The intrahepatic biliary tract is a unique system designed to transport bile from the hepatocytes to the extrahepatic biliary tree.
