Management of Cirrhosis with Ascites and Abdominal Pain
For a patient with cirrhosis and ascites presenting with abdominal pain, the first-line management is empiric antibiotic therapy, as this presentation strongly suggests spontaneous bacterial peritonitis (SBP), which requires immediate treatment to reduce mortality. 1
Initial Diagnostic Approach
Immediate diagnostic paracentesis is mandatory for all cirrhotic patients with ascites presenting with:
- Abdominal pain or tenderness
- Fever
- Signs of systemic inflammation
- Altered mental status
- Worsening liver or renal function 1
Ascitic fluid analysis should include:
- Cell count with differential (PMN count)
- Culture (bedside inoculation into blood culture bottles)
- Total protein, LDH, and glucose 1
Treatment Algorithm
Step 1: Empiric Antibiotic Therapy
Start empiric antibiotics immediately after diagnostic paracentesis in patients with:
- PMN count ≥250 cells/mm³ (definite SBP)
- PMN count <250 cells/mm³ but with signs/symptoms of infection (suspected SBP) 1
First-line antibiotic regimen:
Step 2: Albumin Administration
- Add albumin infusion for patients with SBP who have:
Step 3: Differentiate SBP from Secondary Bacterial Peritonitis
Suspect secondary bacterial peritonitis (which would require surgical intervention) if:
- Multiple organisms on Gram stain/culture
- At least two of the following: total protein >1 g/dL, LDH greater than upper limit of normal for serum, glucose <50 mg/dL
- Inadequate response to antibiotic therapy after 48 hours 1
If secondary peritonitis is suspected:
- Obtain cross-sectional imaging (CT scan)
- Add anaerobic coverage to antibiotic regimen
- Surgical consultation for possible exploratory laparotomy 1
Follow-up Management
Consider repeat paracentesis at 48 hours if:
- Inadequate clinical response to antibiotics
- Suspicion of secondary peritonitis 1
After resolution of SBP:
Important Considerations and Pitfalls
Do not delay paracentesis due to concerns about coagulopathy. Paracentesis is safe in cirrhotic patients despite prolonged prothrombin time. Only consider platelet transfusion if platelets <40,000-50,000/μL 3
Do not delay antibiotic administration while waiting for culture results, as early treatment significantly improves outcomes 1
Avoid nephrotoxic medications (NSAIDs, aminoglycosides) in cirrhotic patients with ascites as they can precipitate renal failure 4
Monitor for complications of SBP including:
- Hepatorenal syndrome
- Worsening hepatic encephalopathy
- Recurrent infection 5
In summary, for a cirrhotic patient with ascites presenting with abdominal pain, the correct answer is A. Antibiotic therapy. Diagnostic laparoscopy (option B) or exploratory laparoscopy (option C) would only be indicated if there is strong evidence of secondary bacterial peritonitis after initial evaluation and treatment failure with antibiotics.
