Study Notes
Definition and Etiology
- Ascites is the abnormal accumulation of fluid in the peritoneal cavity, the space surrounding the abdominal organs.
- This fluid buildup causes abdominal swelling and discomfort.
- Common causes include liver cirrhosis, heart failure, kidney disease, and cancer. Infections and pancreatitis can also contribute.
Pathophysiology
- The mechanisms behind ascites are complex and often multiple.
- Conditions like cirrhosis disrupt the balance between fluid retention and removal, changing protein and hormone activity.
- Portal hypertension, high blood pressure in veins draining the digestive tract, is a key factor in cirrhosis-related ascites. This increased pressure forces fluid from the blood into the abdomen.
- Renal dysfunction reduces the kidney's ability to filter excess fluid, worsening buildup.
Clinical Presentation
- Patients with ascites experience abdominal swelling, fullness, and discomfort.
- Shortness of breath can occur due to diaphragm pressure.
- Other symptoms vary based on the underlying cause, potentially including fatigue, nausea, and weight gain.
- Physical exams may reveal a distended abdomen, fluid wave, and shifting dullness.
Diagnosis
- Clinical evaluation is vital for ascites suspicion.
- Physical exam findings guide further testing.
- Abdominal ultrasound or CT scans confirm fluid buildup and assess the cause.
- Paracentesis, a needle insertion to remove fluid for analysis, confirms fluid properties and helps identify the cause (e.g., infection). It guides treatment.
- Lab tests (complete blood count, liver function tests, and kidney function tests) assess organ system function.
Treatment
- Treatment targets the underlying cause of ascites.
- Diuretics (spironolactone, furosemide) increase urination to reduce fluid retention.
- Dietary sodium restriction is crucial to reduce fluid overload.
- Paracentesis relieves severe ascites when diuretics are insufficient.
- Transjugular intrahepatic portosystemic shunt (TIPS) may be considered to reduce portal hypertension in some cases.
- Infections (e.g., spontaneous bacterial peritonitis) need prompt antibiotic therapy and support.
Complications
- Untreated or poorly managed ascites causes significant complications.
- Severe fluid buildup impairs breathing and other bodily functions.
- Spontaneous bacterial peritonitis (SBP) develops when ascites fluid becomes infected.
- Hepatorenal syndrome is declining kidney function linked to liver disease.
- Increased infection risk and poor nutrition increase morbidity and mortality.
Prognosis
- Ascites prognosis hinges on the underlying cause and liver disease severity.
- Patients with compensated liver disease, managed appropriately, typically have a better prognosis, with reduced symptoms and improved quality of life.
- Progression of underlying conditions worsens quality of life and can lead to serious health issues.
