Cholecystitis Pathology

Cholecystitis is an inflammation of the gallbladder, a small, pear-shaped organ located beneath the liver. The gallbladder stores bile, a fluid produced by the liver that helps digest fats. When bile becomes too concentrated or the flow of bile is blocked, gallstones can form. These gallstones can then irritate and inflame the gallbladder wall, leading to cholecystitis.

Types of Cholecystitis:

• Acute Cholecystitis: This is the most common type of cholecystitis, characterized by sudden and severe inflammation of the gallbladder. It often occurs due to a gallstone blocking the cystic duct, which carries bile from the gallbladder to the small intestine.
• Chronic Cholecystitis: This type of cholecystitis develops over time and is often caused by repeated episodes of acute cholecystitis or long-term irritation from gallstones.

Symptoms of Cholecystitis:

• Pain: The most common symptom is severe pain in the upper right abdomen, which may radiate to the back or shoulder blades. The pain may worsen after eating fatty foods.
• Nausea and Vomiting: These symptoms are often associated with the pain and may persist for several hours.
• Fever: A low-grade fever may be present, especially in cases of acute cholecystitis.
• Jaundice: In some cases, the skin and whites of the eyes may turn yellow, indicating a blockage in the bile ducts.

Pathology of Cholecystitis:

• Gallstone Obstruction: In most cases, a gallstone obstructs the cystic duct, triggering inflammation. This obstruction impedes bile flow, causing it to back up within the gallbladder. The resulting pressure intensifies, further fueling inflammation.

• Bacterial Infection: The stagnant bile within the gallbladder provides an ideal environment for bacterial growth, significantly worsening the inflammation.

• Inflammation and Tissue Damage: Inflammation thickens and swells the gallbladder wall. In severe instances, the gallbladder wall may undergo necrosis (tissue death) or even experience a perforation

Diagnosis of Cholecystitis:

• Ultrasound is the most commonly employed imaging technique for diagnosing cholecystitis. It effectively detects gallstones and identifies signs of inflammation within the gallbladder wall.

• Furthermore, Computed Tomography (CT) scans offer more detailed visualizations of the gallbladder and surrounding structures.

• Finally, healthcare providers may conduct blood tests to assess for elevated levels of white blood cells and liver enzymes, which serve as indicators of inflammation.
