Zorluk: OrtaSurgical and Procedural Interventions

A 78-year-old woman is evaluated in the intensive care unit for new-onset fever and abdominal pain. She was admitted 5 days ago for a massive anterior ST-segment elevation myocardial infarction complicated by cardiogenic shock. She currently remains on a dobutamine infusion for hemodynamic support. Over the past 12 hours, her temperature has risen to 39.2°C (102.6°F) and she has developed significant right upper quadrant abdominal tenderness. Her blood pressure is 88/56 mm Hg and pulse is 115/min. Laboratory studies show a leukocyte count of 18,500/mm³ with a left shift. Liver function tests reveal normal total bilirubin and alkaline phosphatase levels. A bedside right upper quadrant ultrasound demonstrates gallbladder wall thickening of 6 mm, pericholecystic fluid, and a positive sonographic Murphy sign. No gallstones or common bile duct dilation are visualized. Intravenous broad-spectrum antibiotics are initiated. Which of the following is the most appropriate next step in the management of this patient?

  1. Percutaneous cholecystostomy tube placementCevap
  2. B
    Emergent laparoscopic cholecystectomy
  3. C
    Hepatobiliary iminodiacetic acid (HIDA) scan
  4. D
    Endoscopic retrograde cholangiopancreatography (ERCP)
  5. E
    Continuation of current medical management and close observation

Cevap

Percutaneous cholecystostomy tube placement is the most appropriate next step for this critically ill patient with acute acalculous cholecystitis.
The correct intervention is percutaneous cholecystostomy tube placement. This patient has developed acute acalculous cholecystitis (AAC), a severe inflammation of the gallbladder without gallstones that typically occurs in critically ill, hospitalized patients (e.g., those with recent surgery, trauma, burns, or prolonged shock). The diagnosis is confirmed clinically by fever, leukocytosis, and right upper quadrant pain, combined with ultrasound findings of gallbladder wall thickening and pericholecystic fluid. Source control is mandatory because AAC progresses rapidly to gallbladder gangrene and perforation. While laparoscopic cholecystectomy is the definitive treatment for acute cholecystitis, this patient is in cardiogenic shock on dobutamine following a massive myocardial infarction, making her a prohibitively high surgical risk. Percutaneous cholecystostomy provides rapid, minimally invasive biliary decompression and source control without the need for general anesthesia.

Adım Adım Çözüm

1
Analyze the patient's clinical presentation and ultrasound findings.
The patient has fever, leukocytosis, right upper quadrant pain, and ultrasound findings of gallbladder inflammation without stones, confirming the diagnosis of acute acalculous cholecystitis.
Establishing the correct diagnosis is the first step in determining appropriate management.
2
Assess the patient's surgical risk.
The patient is recovering from a massive myocardial infarction and is in active cardiogenic shock requiring dobutamine.
Surgical risk stratification determines whether a patient can safely undergo a definitive surgical procedure like a cholecystectomy.
3
Determine the appropriate intervention based on surgical risk.
Because the surgical risk is prohibitively high, a minimally invasive percutaneous drainage procedure must be selected to achieve necessary source control.
Untreated acalculous cholecystitis is rapidly fatal due to gangrene and perforation; if surgery is contraindicated, percutaneous cholecystostomy is the standard of care.

Anahtar Kavram

Acute acalculous cholecystitis typically occurs in critically ill patients (e.g., sepsis, trauma, cardiogenic shock). Because these patients are usually poor surgical candidates, the treatment of choice is antibiotics and percutaneous cholecystostomy.
