II. Definition

  1. Gallbladder inflammation resulting from cystic duct blockage by Gallstones

III. Precautions

  1. Acute Cholecystitis may present cryptically yet requires emergent management
  2. Fever and chills are frequently absent
    1. Fever or chills are only present in a third of patients with Acute Cholecystitis
  3. Right upper quadrant pain or tenderness may be absent
    1. As many as a quarter of Acute Cholecystitis cases do not have RUQ findings

IV. Symptoms

  1. Biliary Colic with additional characteristics below
    1. Acute Cholecystitis is typically preceded by at least one Biliary Colic episode
  2. Characteristics
    1. Starts as dull visceral poorly localized pain
    2. Develops into sharp parietal focal RUQ Pain
  3. Timing
    1. Pain persists beyond typical 5-6 hours
  4. Associated Symptoms
    1. Fever is present in only 35% of Acute Cholecystitis
    2. Chills are present in only 13% of Acute Cholecystitis

V. Signs

  1. Appearance
    1. Toxic appearance in moderate to severe discomfort
    2. Tachycardia
  2. Non-specific gastrointestinal findings
    1. RUQ Abdominal tenderness
      1. Test Sensitivity: 77%
      2. Test Specificity: 54%
    2. Hypoactive bowel sounds
  3. Peritoneal Signs
    1. Localized irritation is comon
    2. Generalized signs (rare) suggests perforation
  4. Murphy Sign positive
    1. Examiner palpates the abdominal RUQ while the patient takes a deep breath
    2. Positive test if the patient suddenly halts their inspiration due to pain

VI. Labs

  1. Complete Blood Count
    1. Leukocytosis with Left Shift
    2. Normal WBC Count does not rule out Acute Cholecystitis
    3. Very high WBC Count may suggest gallbladder gangrene or perforated gallbladder
  2. Liver Function Tests (LFTs)
    1. Serum Bilirubin elevated (typically mild)
    2. Serum Alkaline Phosphatase elevated
    3. Serum Aminotransferases normal
  3. Pancreatic Studies (for gallstone Pancreatitis)
    1. Serum Lipase (some also obtain Serum Amylase)
  4. Urine Studies
    1. Urinalysis
    2. Urine HCG

VII. Imaging: First-Line

  1. RUQ Ultrasound (preferred)
    1. See Gallbladder Ultrasound for diagnostic criteria
  2. Abdominal CT
    1. Indicated for non-diagnostic Ultrasound
    2. Evaluation of Cholecystitis complications (Ascending Cholangitis, gallstone Pancreatitis, post-operative findings)
  3. Hepatobiliary Iminodiacetic Acid Scan (HIDA Scan)
    1. Acute Cholecystitis evaluation for cystic duct obstruction
    2. Normal gallbladder visualization on HIDA Scan has high Negative Predictive Value (99%)
  4. Magnetic Resonance Cholangiopancreatography (MRCP)
    1. Indicated for suspected Common Duct Stone (Choledocholithiasis)

VIII. Imaging: Other

  1. XRay Abdomen
    1. Test Sensitivity for Gallstones: 10-20%
    2. Most stones are Cholesterol (radiolucent)
  2. Chest XRay
    1. Assess for Right Lower Lobe Pneumonia
    2. Assess for Pleural Effusion (seen in Pancreatitis)
    3. Assess for free air under the diaphragm

IX. Management

  1. Intravenous fluid hydration
  2. Nasogastric suction
  3. Antibiotics
    1. Initial antibiotic regimen (see Cholecystectomy)
      1. Cefazolin 1 gram IV within 1 hour of skin incision
    2. Consider broadening antibiotics for severe cases
      1. Ampicillin with Gentamicin
      2. Ampicillin-Sulbactam
      3. Piperacillin-Tazobactam
  4. Laparoscopic Cholecystectomy
    1. Recommended within first 72 hours
    2. Immediate Cholecystectomy is safe and preferred
    3. Stevens (2006) Am J Surg 192:756-61
  5. Percutaneous cholecystostomy drainage (with delayed Cholecystectomy)
    1. Indicated for older or critically ill patients with gallbladder empyema (and associated Sepsis)
  6. Alternatives to surgery
    1. Extracorporeal Shock Wave Lithotripsy (ESWL)
    2. Oral Dissolution Therapy

X. Course

  1. Spontaneous resolution in 60% of cases

XI. Complications

  1. Acute Pancreatitis
  2. Ascending Cholangitis
  3. Gallbladder Empyema
  4. Gallbladder Gangrene (Emphysematous Cholecystitis)
