🟢 Acalculous Cholecystitis
Acalculous cholecystitis is an inflammation of the gallbladder without gallstones ⚠️
It usually occurs as a complication of a severe medical or surgical condition.
🧪 Causes
1. Increased bile viscosity
Bile stasis and thickened bile may occur in:
🏥 Critically ill patients
🦠 Sepsis patients
💉 Long-term TPN patients
❤️ Cardiac patients
🩸 Diabetic patients
❗ Lack of oral feeding reduces cholecystokinin, leading to poor gallbladder contraction.
2. Gallbladder ischemia
Caused by:
🌡️ Fever
💧 Dehydration
❤️ Heart failure
➡️ This leads to reduced blood flow and gallbladder wall damage.
⚠️ Risk Factors
🩸 Diabetes mellitus
🦠 HIV infection
🧬 Vascular diseases
🧫 Hepatitis A
🏥 Sepsis
❤️ Cardiac or aortic surgery
⛔ Prolonged fasting & malnutrition
🏥 ICU patients
🔥 Burns & trauma
💊 Opioid use
⚠️ Multi-organ failure
🔬 Diagnosis
Diagnosis is based on:
🩸 CBC test
🧪 Liver function tests
🩻 Ultrasound imaging
🖥️ CT scan
📌 Imaging findings:
Gallbladder wall thickening > 3 mm
Gallbladder distension
Abscess or perforation in severe cases
