Classification

Ascites exists in three grades: * Grade 1: mild, only visible on ultrasound and CT * Grade 2: detectable with flank bulging and shifting dullness * Grade 3: directly visible, confirmed with the fluid wave/thrill test

Pathophysiology

Ascitic fluid can accumulate as a

transudate Transudate is extravascular fluid with low protein content and a low specific gravity (< 1.012). It has low nucleated cell counts (less than 500 to 1000 /microliter) and the primary cell types are exudate. Amounts of up to 35 liters are possible. Roughly, transudates are a result of increased pressure in the

concentrations. A difference of less than 1 g/dl (10 g/L) implies an exudate. Portal hypertension plays an important role in the production of ascites by raising capillary hydrostatic pressure within the splanchnic bed. Regardless of the cause, sequestration of fluid within the abdomen leads to additional fluid retention by the kidneys due to stimulatory effect on blood pressure hormones, notably aldosterone. The sympathetic nervous system is also activated, and

Treatment

Ascites is generally treated while an underlying cause is sought, in order to prevent complications, relieve symptoms, and prevent further progression. In people with mild ascites, therapy is usually as an outpatient. The goal is weight loss of no more than 1.0 kg/day for people with both ascites and

level and renal function should be monitored closely while on these medications. Monitoring diuresis: Diuresis can be monitored by weighing the person daily. The goal is weight loss of no more than 1.0 kg/day for people with both ascites and

and no more than 0.5 kg/day for people with ascites alone. If daily weights cannot be obtained, diuretics can also be guided by the urinary sodium concentration. Dosage is increased until a negative sodium balance occurs. A random urine sodium-to-potassium ratio of > 1 is 90% sensitivity in predicting negative balance (> 78-mmol/day sodium excretion). Diuretic resistance: Diuretic resistance can be predicted by giving 80 mg intravenous furosemide after 3 days without diuretics and on an 80 mEq sodium/day diet. The urinary sodium excretion over 8 hours < 50 mEq/8 hours predicts resistance. If the person exhibits a resistance or poor response to diuretic therapy,

In those with severe (tense) ascites, therapeutic

may be needed in addition to medical treatments listed above. As this may deplete

levels in the blood, albumin is generally administered intravenously in proportion to the amount of ascites removed.

Surgery

Ascites that is refractory to medical therapy is considered an indication for liver transplantation. In the United States, the MELD score

is used to prioritize people for transplantation. In a minority of people with advanced cirrhosis that have recurrent ascites, shunts may be used. Typical shunts used are portacaval shunt,

concluded that "TIPS was more effective at removing ascites as compared with paracentesis...however, people with TIPS develop hepatic encephalopathy significantly more often". Another potential treatment option for patients with refractory/malignant ascites is the alfapump, (automated low flow ascites pump) which is an implantable device that removes ascites out of the peritoneal cavity and transports it via the pump into the bladder, where it passed naturally from the body through urination.

Low SAAG ("exudative") ascites

Exudative ascites generally does not respond to manipulation of the salt balance or diuretic therapy. Repeated paracentesis and treatment of the underlying cause is the mainstay of treatment.

Society and culture

It has been suggested that ascites was seen as a punishment especially for
