Zorluk: OrtaSurgical and Procedural Interventions

While recovering in the intensive care unit from a severe exacerbation of chronic obstructive pulmonary disease requiring mechanical ventilation, a 74-year-old male develops a new-onset fever of 38.9°C (102.0°F) and increasing vasopressor requirements. His medical history includes coronary artery disease, chronic obstructive pulmonary disease, and heart failure with preserved ejection fraction. Physical examination reveals a distended abdomen with focal guarding in the right upper quadrant. Laboratory studies show a leukocyte count of 18,500/mm³ and mild elevations in aspartate aminotransferase and alanine aminotransferase, with a normal total bilirubin level. A bedside right upper quadrant ultrasound demonstrates gallbladder wall thickening to 6 mm, pericholecystic fluid, and a sonographic Murphy sign, without intrahepatic or extrahepatic biliary ductal dilation. Which of the following is the most appropriate procedural intervention for this patient's current abdominal condition?

  1. A
    Laparoscopic cholecystectomy
  2. B
    Endoscopic retrograde cholangiopancreatography
  3. Placement of a percutaneous cholecystostomy tubeCevap
  4. D
    Hepatobiliary iminodiacetic acid scintigraphy
  5. E
    Transition to exclusive palliative care without further procedural intervention

Cevap

Placement of a percutaneous cholecystostomy tube is the correct intervention for this hemodynamically unstable patient with acute cholecystitis.
The correct answer is placement of a percutaneous cholecystostomy tube. This patient is suffering from acute cholecystitis, which is driving his septic shock. While the definitive treatment for acute cholecystitis is a laparoscopic cholecystectomy, this patient is critically ill (mechanically ventilated, requiring vasopressors) and is a prohibitive surgical risk. In such high-risk patients, a percutaneous cholecystostomy tube placed under image guidance allows for decompression and drainage of the infected gallbladder, providing adequate source control while avoiding the physiological stress of general anesthesia and surgery. Once the patient recovers from the acute illness, a delayed cholecystectomy can be reconsidered.

Adım Adım Çözüm

1
Identify the primary diagnosis based on clinical and radiographic findings.
The patient has acute cholecystitis, evidenced by right upper quadrant guarding, fever, leukocytosis, and characteristic ultrasound findings (thickened gallbladder wall, pericholecystic fluid).
Establishing the acute intra-abdominal process is necessary to target therapy.
2
Assess the patient's surgical risk and hemodynamic status.
The patient is on mechanical ventilation, requires increasing vasopressors, and has severe cardiopulmonary comorbidities, classifying him as critically ill and a prohibitively high-risk surgical candidate.
Surgical risk stratification determines whether the patient can safely undergo definitive operative management (cholecystectomy).
3
Select the most appropriate therapeutic intervention for a poor surgical candidate.
Determine that percutaneous cholecystostomy provides necessary source control for the infected gallbladder without the risks associated with general anesthesia and surgery.
Drainage of the infected source is mandated in sepsis, but must be balanced against the patient's ability to tolerate the procedure.

Anahtar Kavram

Percutaneous cholecystostomy is the preferred initial procedural intervention for acute cholecystitis in critically ill patients who are hemodynamically unstable or otherwise poor candidates for surgery.
