Management of Ascites in Cirrhosis: Key Recommendations from the British Society of Gastroenterology Guidelines
12 Oct, 2024 | 18:23h | UTCIntroduction: Ascites, the pathological accumulation of fluid within the peritoneal cavity, is a common and serious complication of cirrhosis, indicating advanced liver disease and portending increased morbidity and mortality. Recognizing the need for updated clinical guidance, the British Society of Gastroenterology (BSG), in collaboration with the British Association for the Study of the Liver (BASL), has issued comprehensive guidelines. These aim to standardize the diagnosis and management of ascites in cirrhotic patients, incorporating recent advances to optimize patient outcomes.
Key Recommendations:
- Diagnostic Paracentesis: It is strongly recommended that all patients with new-onset ascites undergo diagnostic paracentesis to measure total protein concentration and calculate the serum-ascites albumin gradient (SAAG). (Quality of evidence: moderate; Recommendation: strong)
- Spontaneous Bacterial Peritonitis (SBP): Prompt diagnostic paracentesis should be performed in hospitalized patients with ascites, especially those with gastrointestinal bleeding or signs of infection, to rule out SBP. An ascitic neutrophil count >250/mm³ confirms SBP, necessitating immediate empirical antibiotic therapy tailored to local resistance patterns. (Quality of evidence: moderate; Recommendation: strong)
- Dietary Salt Restriction: Patients should restrict dietary sodium intake to no more than 5–6.5 grams per day (87–113 mmol), equivalent to a no-added-salt diet, to manage fluid accumulation effectively. (Quality of evidence: moderate; Recommendation: strong)
- Diuretic Therapy: For initial moderate ascites, spironolactone monotherapy is recommended. In cases of recurrent severe ascites, combination therapy with spironolactone and furosemide is advised. Regular monitoring for adverse events such as electrolyte imbalances and renal impairment is essential. (Quality of evidence: moderate; Recommendation: strong)
- Large Volume Paracentesis (LVP): LVP is a safe and effective treatment for refractory ascites. Informed consent is required, and routine coagulation studies or prophylactic blood product infusions before the procedure are not recommended. (Quality of evidence: moderate; Recommendation: strong)
- Use of Human Albumin Solution (HAS): After LVP exceeding 5 liters, infusion of HAS at 8 grams per liter of ascites removed is strongly recommended to prevent circulatory dysfunction. (Quality of evidence: high; Recommendation: strong)
- Transjugular Intrahepatic Portosystemic Shunt (TIPSS): TIPSS should be considered for patients with refractory ascites not responding to medical therapy, with caution exercised in patients over 70 years or those with significant comorbidities. (Quality of evidence: high; Recommendation: strong)
- Non-Selective Beta-Blockers (NSBBs): The presence of refractory ascites is not a contraindication for NSBB therapy. Patients should be closely monitored, and dose adjustments made in cases of hypotension or renal dysfunction. (Quality of evidence: moderate; Recommendation: strong)
- Palliative Care: Patients unsuitable for liver transplantation should be offered palliative care referral to focus on symptom management and quality of life improvement. Alternative interventions for refractory ascites may also be considered. (Quality of evidence: weak; Recommendation: strong)
Conclusion: Implementation of these evidence-based guidelines is expected to enhance patient care by promoting early diagnosis, preventing complications, and standardizing management strategies for ascites in cirrhosis. Adherence to these recommendations can improve clinical outcomes, reduce hospitalizations, and enhance the quality of life for affected patients.
