A

Jaundice, spider nevi, palmar erythema, and paper-money skin.

28
Q

What is cholelithiasis (Gallstones)?

A

Formation of stones in the gallbladder due to imbalances in bile composition.

29
Q

Describe the major substance(s) of gallstones

A

Cholelithiasis or gallstones is caused by precipitation of substances contained in bile, mainly cholesterol and bilirubin.

30
Q

Describe the two primary factors that contribute to the formation of gall stones

A

Two primary factors contribute to the formation of gallstones: abnormalities in the composition of bile (particularly increased cholesterol) and the stasis of bile.

31
Q

What are the risk factors for gallstones / what conditions are associated with formation of gallstones?

A

Sex(Female), obesity, multiple pregnancies, rapid weight loss, and high-fat diets. Contraceptive pills.

32
Q

What are the symptoms of cholelithiasis? And when do people experience symptoms

A

Many people have no symptoms. Gallstones cause symptoms when they obstruct bile flow or cause inflammation. Larger stones are more likely to obstruct flow and cause jaundice. The pain of biliary colic is usually located in the upper right quadrant.

33
Q

What complications can arise from gallstones?

A

Cholecystitis, cholangitis, and choledocholithiasis.

34
Q

What is cholecystitis?

A

Inflammation of the gallbladder, usually due to gallstones.

35
Q

What is acute cholecystitis?

A

Acute cholecystitis is a diffuse inflammation of the gallbladder, usually caused by obstruction of the gallbladder outlet, most commonly due to gallstones (calculous cholecystitis).

36
Q

What percentage of acute cholecystitis cases are associated with gallstones?

A

Approximately 85% to 90% of cases are associated with gallstones (calculous cholecystitis).

37
Q

What is acalculous cholecystitis?

A

Acalculous cholecystitis is gallbladder inflammation that occurs without gallstones. It is often associated with sepsis, severe trauma, infection, burns, biliary sludge, or vasculitis.

38
Q

What is chronic cholecystitis?

A

Chronic cholecystitis results from repeated episodes of acute cholecystitis or chronic irritation by gallstones. It is characterized by varying degrees of chronic inflammation and almost always involves gallstones.

39
Q

What complications are associated with chronic cholecystitis?

A

Complications include acute exacerbations of inflammation, common duct stones, pancreatitis, and, rarely, gallbladder carcinoma.

40
Q

What are the clinical manifestations of acute cholecystitis?

A

Symptoms include sudden onset of upper right quadrant or epigastric pain, mild fever, anorexia, nausea, and vomiting. Pain may be severe and sudden, sometimes requiring emergency surgery.

41
Q

What are the symptoms of chronic cholecystitis?

A

Symptoms are more vague and include intolerance to fatty foods, belching, and episodes of colicky pain due to biliary obstruction caused by gallstones.

42
Q

What is acute pancreatitis?

A

Sudden inflammation of the pancreas due to enzyme activation and autodigestion.

43
Q

What are the main causes of acute pancreatitis?

A

Gallstones and alcohol abuse.

44
Q

What are the symptoms of acute pancreatitis?

A

Severe epigastric pain radiating to the back, nausea, vomiting, and fever.

45
Q

What are complications of chronic pancreatitis?

A

Diabetes, malabsorption, pseudocysts, and pancreatic cancer.

46
Q

What is hepatocellular carcinoma (HCC)?

A

A primary liver cancer arising from hepatocytes, often linked to cirrhosis and hepatitis.

47
Q

What is cholangiocarcinoma?

A

Cancer of the bile ducts, associated with chronic inflammation or primary sclerosing cholangitis.

48
Q

What are common symptoms of hepatobiliary cancers?
