Approach - Management of ascites in cirrhotic patientsDr . Khaled sheha
Causes of ascites Causative disorders Percentage Cirrhosis 85% PHT-related disorder 8% Cardiac disease 3% Peritoneal carcinomatosis 2% Miscellaneous non-PHT disorders 2%
Diagnosis of ascites* • Ascites can be graded as Grade 1 (mild) Detectable only by US Grade 2 (moderate) Moderate abdominal distension Grade 3 (large) Marked abdominal distension * Moore KP et al. Hepatology 2003 ; 38 : 258 – 66.
Ascites grade 1 Detectable only by US
Pathogenesis of ascites in cirrhosis PHT • Nitric oxide Vasodilatation Renal Na retention Overfill of intravascular volume Sympathetic activity RAA system Ascites formation
Indications for diagnostic paracentesis • Patients with new-onset ascites • Cirrhotic patients with ascites at admission • Cirrhotic patients with ascites & symptoms or signs of infection: fever, leukocytosis, abdominal pain • Cirrhotic patients with ascites & clinical condition deteriorating during hospitalization: renal function impairment, hepatic encephalopathy, GI bleeding
Needle-entry sites Superior & inferior epigastric arteries run just lateral to the umbilicus towards mid-inguinal point & should be avoided .
The Z-tract technique Green (21 G) or blue (23 G) needle Diagnostic purpose: 10- 20 ml of fluid ascites Cytologic study: 50 ml of fluid ascites Thomsen TW et al. N Engl J Med 2006 ; 355 : e21.
The angular insertion technique Green (21 G) or blue (23 G) needle Diagnostic purpose: 10- 20 ml of fluid ascites Cytologic study: 50 ml of fluid ascites .
What are the contraindications & complications of paracentesis? MA
Complications of paracentesis • Abdominal hematomas Up to 1 % of patients Rarely serious or life threatening • Hemoperitoneum or bowel perforation Rare (< 1/1000 procedures) Serious complications Guidelines on management of ascites in cirrhosis. Gut 2006 ; 55 ; 1 – 12 .
Contraindications to paracentesis • Clinically evident fibrinolysis or DIC Preclude paracentesis • Abnormal coagulation profile Paracentesis not contraindicated Majority of pts have prolonged PT & thrombocytopenia No data to support the use of FFP before paracentesis AASLD practice guidelines Runyon BA. Hepatology 2004; 39: 841 – 856.
Ascitic Fluid Laboratory Data Routine Optional Unusual Unhelpful Cell count * Albumin Total protein Culture Glucose LDH Amylase Gram’s stain TB smear & culture Cytology TG Bilirubin pH Lactate Cholesterol Fibronectin * Automated counting can replace manual cell count .
Serum Ascites Albumin Gradient (SAAG) AlbuminSerum – AlbuminAscites (g/dL) (g/dL) in the same day
Differential diagnosis according to SAAG High Gradient ≥ 1.1 g/dL Low Gradient < 1.1 g/dL .

What do you prescribe to this patient?What are the side effects of these drugs?How do you follow-up the patient? ND
RecommendationLow sodium diet Dietary salt should be restricted to a no-added salt diet of 90 mmol salt/day (5.2 g salt/day) by adopting a no-added salt diet & avoidance of pre-prepared foodstuffs ND
Diuretics treatment in cirrhotic ascitesOral route – Single morning dose Progressive Schedule Combined Schedule SP 100 mg/d + FUR 40 mg/d SP * 100 200 300 400 mg/d Progressive increase every 3-5 days SP 400 mg/d + FUR** 40 80 120 160 mg/d SP 200 300 400 mg/d + FUR 80 120 160 mg/d *SP Spironolactone **FUR Furosemide
Follow-up of patients on diuretics – 1 • Weight loss Massive edema No limit to daily weight loss Resolved edema 0.5 kg / day • Weight loss less than desired 24-hour urine sodium > 78 mmol/24h & no weight loss: patient not compliant < 78 mmol/24h & no weight loss: increased diuretics “spot” urine NA/K>1= 24-hour urine Na>78 mmol/24h
Follow-up of patients on diuretics – 2 • Body weight • Blood pressure • Pulse • Electrolytes • Urea • Creatinine Every 2 – 4 weeks Every few months thereafter
Side effects of diuretics • Spironolactone Men libido, impotence, gynecomastia Women Menstrual irregularity • Hydro-electrolytes disturbances Hypovolemia: hypotension – renal insufficiency Hyponatremia Hypo or hyperkalemia Hepatic encephalopathy
Water restriction • Not necessary in most cirrhotic patients with ascites • Cirrhotic patients have symptoms from hyponatremia if Na < 110 mmol/L or if very rapid decline in Na • Water restriction indicated in patients who are clinically euvolaemic withs severe hyponatraemia & not taking diuretics with normal creatinine • Avoid increasing serum sodium > 12 mmol/l per day ND
Bed rest in cirrhotic ascites • Upright posture associated with activation of RAA system, reduction in GFR & sodium excretion, & decreased response to diuretics • Bed rest muscle atrophy & other complications • No clinical studies to demonstrate efficacy of bed rest
RecommendationBed rest Bed rest is NOT necessary for the treatment of cirrhotic ascites
Is this a refractory ascites?How do you treat refractory ascites? RA
Refractory ascites ( 10 %) • Diuretic resistant ascites Unresponsive to LSD (< 88 mmol/day) & High-dose diuretics SP 400 mg & FUR 160 mg/d • Diuretic intractable ascites Diuretic induced complications Encephalopathy Creatinine > 2.0 g/dL Na < 125 mmol/L K > 6 or < 3 mmol/L for at least 1 week International ascites club Arroyo V et al. Hepatology 1996 ; 23 : 164 – 76.
RecommendationsTreatment of refractory ascites • Therapeutic paracentesis is the first line treatment: < 5 L: Colloid - No need for albumin > 5 L: Albumin after paracentesis (8g/l) • TIPS should be considered in refractory ascites • LT referral should be considered in refractory ascites • Peritoneovenous shunt should be considered in patients who are not candidates for paracentesis, TIPS, or LT ND
Refractory Ascites LT evaluation LVP + Albumin 1st Step Na restricted diet (90 mEq/d) Fluid restriction if Na < 130 mEq/L Repeated LVP + albumin Maintenance Treatment Preserved liver function? Loculatedascites? Paracentesis more frequent than 2-3 /month? No Yes Continue LVP + Albumin Consider TIPS Clin Gastroenterol Hepatol 2005 ; 3 : 1187 – 1191.
Treatment of refractory ascites • Serial therapeutic paracentesis • TIPS • Liver transplantation • Peritoneovenous shunt: LeVeen – Denver
TIPS for refractory ascites Is practice guidelines Runyon BA. Hepatology 2004; 39: 841 – 856.
Albumin in cirrhotic ascites • Large paracentesis > 5 L 8 g albumin/liter of ascites removed (100 ml of 20% albumin / 3 L ascites) • SBP with renal impairement First six hours 1.5 g albumin / kg bw Day 3 1g albumin / kg bw • HRS-I First day 1 g / kg bw (maximum 100 g) Following days 20 – 40 g / day
Prognosis of ascites in cirrhotic patients • Ascites 50 % survival at 2 years • Refractory ascites 50% survival at 6 months 25% survival at 1 year • SBP 30 - 50% survival at 1 year • HRS-2 40% survival at 6 months • HRS-1 < 5% survival at 6 months Referral to liver transplantation unit
