Benign tumours of the gallbladder and gallbladder stone disease populations.
Anatomical background:
The gallbladder is a small sac-like organ located on the visceral surface of the liver. Bile is produced in the liver and then, in response to appropriate neural, endocrine and paracrine influences, it plays a role in breaking down fats or oils in the gallbladder into smaller particles by contracting the gallbladder and relaxing the small muscular ring in the wall of the duodenum. The gallbladder is supplied with blood by a small artery.
Pathophysiological features:
In our population, stone formation is caused by an imbalance in bilirubin (bile pigment), calcium and cholesterol balance. Certain diseases can lead to elevated calcium levels, which, in addition to kidney stone formation, are involved in the development of gallbladder and gallstones. In such cases, it is always advisable to investigate the underlying disease in addition to removing the gallbladder. Other pathological conditions lead to the accumulation of gallstones.
The cause of benign tumours of the gallbladder is not known, but polyps with a large or growing tendency in the gallbladder wall should also be removed because of the risk of malignant transformation.
Complaints are raised when a large gallstone blocks the gallbladder duct, causing the gallbladder to increase in pressure and the gallbladder wall to become strained. If the stone is dislodged and the bile is allowed to drain, the crampy abdominal symptoms may disappear. In the absence of bile evacuation, the pressure increases and the bile may become over-infected with bacteria due to the bile spasm, eventually causing inflammation of the gallbladder. It is best to remove the gallbladder within 72 hours of the onset of inflammation.
If the inflammation is prolonged, perforation of the gallbladder, biliary peritonitis or liver abscess may develop.
Smaller stones can pass through the gallbladder duct into the bile ducts and block them, which is known as bile duct fouling. The first sign of stagnant bile in the liver may be yellow discolouration of the skin and cornea. The stools may become colourless and clay-like and the urine dark. Prolonged stasis can trigger inflammation of the bile ducts.
Bile duct stones may also block the pancreatic duct, wedged into a small opening in the duodenum, and pancreatitis may develop.
The exact cause of gallbladder tumours, which have a poor oncological prognosis, is currently unknown, but decades of chronic inflammation caused by gallstones may play a role in the development of gallbladder cancer. This is confirmed by the fact that gallbladder tumours do not usually develop in a stone-free gallbladder.
What are the symptoms of gallbladder disease?
Gallbladder stones or polyps cause typical symptoms in the majority of cases.
jaundice
spasmodic pain under the right costal arch after eating, radiating towards the right shoulder blade and the vertebrae.
pain may also occur in the middle part of the abdomen
If the above symptoms are associated with fever, or if the abdominal pain does not subside with painkillers and antispasmodics, the possibility of gall bladder inflammation is also raised.
Some patients with gallstones are asymptomatic. However, removal of the gallbladder is still recommended to prevent further complications.
What tests are needed?
Recommended when typical symptoms appear:
- an abdominopelvic UH scan
- laboratory tests to check liver capacity, levels of bile acids, pancreatic enzymes and inflammatory parameters
- ERCP (endoscopic retrograde cholangiopancreatography) or biliary intervention may be necessary.
In rare cases, CT, MRI, MRCP may be required as an additional investigation.
