Management of ascites. Paracentesis as a guide

Area of Science:

• Gastroenterology
• Hepatology
• Internal Medicine

Background:

• Ascites, the accumulation of fluid in the abdominal cavity, is a common complication of liver disease and other conditions.
• New-onset ascites or changes in existing ascites necessitate prompt evaluation to rule out serious complications.

Purpose of the Study:

• To outline the diagnostic and therapeutic strategies for managing patients with ascites.
• To emphasize the importance of paracentesis in diagnosing ascites-related complications and guiding treatment.

Main Methods:

• Diagnostic paracentesis to analyze ascitic fluid for infection and aid differential diagnosis.
• Serum-ascites albumin gradient measurement to identify portal hypertension.
• Neutrophil count in ascitic fluid for diagnosing spontaneous bacterial peritonitis.
• Treatment with parenteral antibiotics, sodium restriction, diuretics, and consideration of advanced therapies for refractory cases.

Main Results:

• A serum-ascites albumin gradient > 1.1 g/dL suggests portal hypertension.
• Spontaneous bacterial peritonitis is diagnosed by ascitic fluid neutrophil count and treated with antibiotics.
• Low-protein ascites in hospitalized patients warrants antibiotic prophylaxis.
• Refractory ascites may benefit from large-volume paracentesis, shunting procedures, or liver transplantation.

Conclusions:

• Diagnostic paracentesis is essential for accurate ascites characterization and management.
• Prompt diagnosis and treatment of spontaneous bacterial peritonitis are critical.
• A stepwise approach, from diuretics to advanced interventions and transplantation, is necessary for managing complex ascites cases.
