2 Ascitis refractaria. Definición
Ascitis que no puede movilizarse o su recurrencia precoz que no puede evitarse con tratamiento diurético. ascitis resistente a los diuréticos: ausencia de respuesta a la dieta hiposódica y al tratamiento diurético intensivo (Esp 400 mg/día + F 160 mg/día)). ascitis intratable con diuréticos: desarrollo de complicaciones inducidas por los diuréticos que impiden el uso de dosis adecuadas de diuréticos. Accordingly to the International Ascites Club, refractory ascites was defined as the ascites that cannot be mobilized or the early recurrence of which cannot be satisfactorily prevented by medical therapy. The term refractory ascites includes the following two subtypes: a) diuretic-resistance ascites due to a lack of response to dietary sodium restriction and intensive diuretic therapy (spironolactone 400 mg/day plus furosemide 160 mg/day); and b) diuretic-intractable ascites due to the development of diuretic-induced complications, such as encephalopathy, renal failure, hyponatremia and hypo- or hyperkalemia, that preclude the use of an effective diuretic dosage.

6 WORSENING OF CIRRHOSIS LEADS TO WORSENING OF ASCITES AND HEPATORENAL SYNDROME
deterioro hepatopatía Cirrosis Resistencia intrahepática Resistencia arteriolar sistémica Presión sinusoidal Volumen arterial efectivo Ascitis refractaria Retención sodio y agua Ascitis Activación sistemas neurohumorales Cirrhosis leads to increased intrahepatic resistance and thereby to an increased sinusoidal pressure. In addition, portal hypertension leads to splanchnic and systemic arteriolar vasodilation, decreased effective arterial blood volume, upregulation of sodium-retaining hormones, sodium and water retention and consequently, plasma volume expansion. With progression of cirrhosis and portal hypertension, the systemic arteriolar resistance is more pronounced, leading to further activation of the renin-angiotensin-aldosterone and sympathetic nervous systems. The resulting increase in water and sodium retention can lead to refractory ascites while the increase in renal vasoconstriction can lead to a functional renal failure, the hepatorenal syndrome.

Diuréticos Anastomosis peritoneovenosa Paracentesis total Derivación portosistémica percutánea intrahepática Trasplante hepático Until the last decade peritoneovenous shunting was the only therapeutic alternative in cirrhotic patients with refractory ascites. However, peritoneovenous shunting does not improve survival in these patients, has serious complications, and it is associated with a high rate of obstruction of the shunt. More recently, large-volume paracentesis, the transjugular intrahepatic portosystemic shunt (TIPS), and liver transplantation have been used in the treatment of refractory ascites.

Therefore, ascites recurrence is the rule. LVP consists of the direct removal of ascitic fluid from the peritoneal cavity through a needle. It is performed in association with albumin as a plasma volume expander in order to increase the effective arterial blood volume. Activación sistemas vasoactivos Retención sodio y agua Ascites

Tratamiento estándar en la ascitis refractoria al ser eficaz y segura en la eliminación de la ascitis. Puede producir DCP: mayor recurrencia de la ascitis y reducción de la supervivencia. Tratamiento local que no modifica los mecanismos responsables de la formación de ascitis, por lo que la recidiva de la ascitis es muy frecuente. Currently, the treatment of choice for refractory ascites in most centers, both for patients awaiting liver transplantation and patients who are not candidates to transplantation, is repeated large-volume paracentesis associated with intravenous albumin since this treatment is effective and safe in the elimination of ascites. Albumin is intented to correct the decreased effective arterial blood volume that drives sodium retention in cirrhosis and maintains ascites formation. Large volume paracentesis can lead to postparacentesis circulatory dysfunction, mainly when paracentesis is performed without plasma expansion with albumin. This vascular complication is associated with faster recurrence of ascites and reduction in survival. Since therapeutic paracentesis is a local therapy that does not modify the mechanisms that lead to ascites formation, ascites will always recur in patients with refractory ascites unless there is an improvement in liver disease (i.e.alcoholic hepatitis).

11 POST-PARACENTESIS CIRCULATORY DYSFUNCTION (PCD) DEPENDS ON THE TYPE OF PLASMA VOLUME EXPANDER AND THE AMOUNT OF ASCITES REMOVED La disfunción circulatoria post-paracentesis (DCP) depende del tipo de espansor plasmático y del volumen de ascitis extraído Desarrollo de DCP % Ascitis extraída Global <5-6 L >5-6 L 70 60 50 40 30 20 10 No espansor Fisiológico Espansor sintético Albúmina Two factors have been shown to be independently predictive of the development of PCD: the amount of ascites extracted and the type of plasma volume expander used at the time of large volume paracentesis (LVP). The incidence of PCD can be as high as 80% if no plasma expander is given at the time of LVP. If less than 5 liters of ascites are removed, the incidence of PCD is the same (~10%) using albumin, synthetic expanders or saline solution. However, if more than 5 liters are removed, the lowest rate of PCD is observed with albumin (~18) with significantly higher rates observed with the administration of synthetic plasma expanders (~40%) or saline solution (~55%). Therefore, albumin should be used with LVP when 5 of more liters of ascites are removed.

12 Anastomosis peritoneovenosa en la ascitis refractaria
PERITONEO-VENOUS SHUNT (PVS) IS USEFUL IN THE TREATMENT OF REFRACTORY ASCITES Anastomosis peritoneovenosa en la ascitis refractaria Válvula uni-direccional The peritoneovenous shunt (PVS) consists of a silicone tube system with a distal fenestrated limb that is placed in the peritoneal cavity and is connected through a one-way pressure-sensitive valve to a tube that is tunneled under the skin and placed into the right atrium. The shunt can be placed under local anesthesia and has been shown to eliminate ascites, increase diuresis and the response to diuretics and to markedly suppress renin, aldosterone, norepinephrine and antidiuretic hormone, indicative of an improvement in the circulatory state. Unfortunately, PVS becomes obstructed at a high rate (50% in the first year). Placement of a PVS may hinder future placement of TIPS and may complicate liver transplant surgery given its ability to produce peritoneal adhesions. Therefore, PVS is mostly indicated in patients who require LVP frequently and who are not candidates for TIPS or for transplant.

13 Paracentesis vs. anastomosis peritoneovenosa
170 pacientes cirróticos con ascitis refractoria Paracentesis + Albúmina (8 g/L) 83 pacientes LeVeen Shunt 48 pacientes LeVeen Shunt + Punta titanio 39 pacientes At present, two randomized controlled trials have been performed comparing therapeutic paracentesis with peritoneovenous shunting in cirrhotic patients with refractory ascites. The first one was published in N Engl J Med in 1991 and the second in Hepatology in The design of both studies was almost identical. A total of 170 cirrhotic patients with refractory ascites were included in both trials. 83 of them were treated with total or repeated paracentesis associated with iv albumin (8 g per liter of ascites removed) and 87 with LeVeen shunt. In 39 of them, a titanium-tip was inserted at the venous end of the prosthesis to prevent obstruction at that level. Alta con diuréticos N Engl J Med 1991; Hepatology 1995

14 Paracentesis vs. anastomosis peritoneovenosa
N Engl J Med 1991; Hepatology 1995 Probabilidad de obstrucción del shunt APV Mejora el control a largo plazo de la ascitis, pero..... no mejora la supervivencia y requiere reintervenciones frecuentes global The results of these studies demonstrate that peritoneovenous shunting improves the long-term control of ascites since it markedly increased the time to first readmission for ascites, and significantly decreased the number of readmissions for ascites, but…. It does not prolong survival, and it requires frequent reopearation because of shunt obstruction (approximately 45% at 1-year of follow-up), which was not prevented by the insertion of a titanium-tip at the venous end of the prosthesis. In fact, the probability of obstruction attributable to clotting at the venous end of the shunt was approximately 20% a 1-year of follow-up in the Hepatology study, a figure very similar when the titanium tip was not used. In summary, the results of these studies indicate that paracentesis is an alternative treatment to peritoneovenous shunting in refractory ascites. With the advent of alternative therapies for refractory ascites, and with progressively fewer and fewer surgeons trained in the surgical procedure, peritoneovenous shunting is now no longer the treatment of choice for refractory ascites.

Unfortunately, PVS becomes obstructed at a high rate (50% in the first year). Placement of a PVS may hinder future placement of TIPS and may complicate liver transplant surgery given its ability to produce peritoneal adhesions. Therefore, PVS is mostly indicated in patients who require LVP frequently and who are not candidates for TIPS or for transplant.

16 THE TRANSJUGULAR INTRAHEPATIC PORTOSYSTEMIC SHUNT
Derivación portosistémica percutánea intrahepática (DPPI) Vena hepática DPPI Vena esplénica Portal hypertension can be corrected by creating a communication between the hypertensive portal system and low-pressure systemic veins, bypassing the liver, i.e., the site of increased resistance. This communication can be created surgically or by the transjugular placement of an intrahepatic stent that connects a branch of the portal vein with a branch of an hepatic vein, a procedure designated transjugular intrahepatic porto-systemic shunt (TIPS). TIPS is performed by advancing a catheter introduced through the jugular vein into a hepatic vein and into a main branch of the portal vein. An expandable stent is then introduced connecting hepatic and portal systems, and blood from the hypertensive portal vein and sinusoidal bed is shunted to the hepatic vein. The procedure is highly effective in correcting portal hypertension but can be associated with complications related to diversion of blood flow away from the liver, namely portal-systemic encephalopathy and liver failure.

In addition, it also increases the effective arterial blood volume by shunting portal venous blood into the systemic circulation. However, by bypassing the liver this therapy can lead to other complications such as encephalopathy and liver failure. Activación sistemas vasoactivos Retención sodio y agua Ascitis

Encefalopatía hepática (15-30%) Deterioro de la función hepática Estenosis-obstrucción de la prótesis (30-60%) Aumento mortalidad en pacientes Child C Despite its potentital advantages for the treatment of ascites, TIPS has important limitations. Like surgical portosystemic shunts, TIPS can lead to liver failure and hepatic encephalopathy in 15 to 30% of cases as a result of diversion of blood away from the liver into the systemic circulation. Another important problem of TIPS is its high rate of dysfunction/occlusion, which occurs in 50-70% of patients during the first year. This is an important limitation of TIPS requiring frequent retreatments. Finally, an increased mortality rate was reported in Child C patients treated with TIPS.

This table summarizes the main characteristics of the patients included in these trials. Please note that in the study by Lebrec et al only 25 patients were included, 13 in the TIPS group an 12 in the paracentesis one, a sample size too small to allow for valid conclusions. On the other hand, the trial of Rössle et al. was not made in a population of patients with true refractory ascites. In this study a significant proportion of patients had recidivant or recurrent ascites instead of true refractory ascites. This is clearly illustrated by a very high mean baseline urine sodium of patients included (greater than 45 mmol/d), a feature not compatible with the existance of true refractory ascites which is characterized by extremely low urine sodium, ussually lower than 10 mmol/d.

Conclusiones La DPPI mejora el control de la ascitis, pero su uso se asocia con un aumento de la frecuencia y gravedad de la encefalopatía No mejora la supervivencia, pero existe una tendencia favorable En futuros estudios con DPPI, seleccionar pacientes según bilirrubina y evitar los que presentan riesgo elevado de encefalopatía post-DPPI ¿Coste del tratamiento? ¿Calidad de vida? In conclusion, although TIPS improves the control of ascites and prevents the occurrence of hepatorenal syndrome in patients with cirrhosis and refractory ascites, its use is associated with an increased frequency and severity of hepatic encephalopathy, does not improve survival, and has a higher cost compared with repeated paracentesis and albumin. Therefore, repeated total paracentesis with albumin should be considered the first treatment option of refractory ascites. D’Amico et al. Gastroenterology 2005;129:

37 Sumario (I) En todo paciente con ascitis refractaria ha de evaluarse la posibilidad de un trasplante hepático. La paracentesis total repetida con albúmina ev es actualmente el primer tratamiento de elección. Los pacientes pueden continuar con tratamiento diurético si lo toleran y es algo efectivo. In summary, since the development of refractory ascites is associated with a poor prognosis, the possibility of a liver transplantation should be considerer in every cirrhotic patients with refractory ascites. Currently, the first line treatment of refractory ascites is repeated total paracentesis associated with intravenous albumin administration. To reduce the frequency of repeated paracentesis, patients may continue to receive diuretics as long as they tolerate. However, diuretics should be stopped if there are significant complications or the urine sodium is below 30 mmols/day.

38 Sumario (II) La DPPI puede recomendarse en pacientes que no toleran la paracentesis total repetida (3 o más paracentesis por mes?), o si la paracentesis no puede evacuar la ascitis. La DPPI está contraindicada en pacientes con un Child-Pugh de 13 o más puntos, encefalopatía crónica o cardiopatía. En los no candidatos a trasplante, la anastomosis peritoneovenosa en caso de fracaso de la paracentesis o contraindicaciones a la DPPI. TIPS could be recommended in patients who do not tolerate repeated total paracentesis. This is generally agreed at 3 or more paracentesis per month, but may vary depending on patient tolerance. TIPS is also indicated if paracentesis fails to adequately remove ascitic fluid (I.e. loculated ascites). By contrast, TIPS is contraindicated in patients with a Child Pugh score of 12 or more, overt or chronic hepatic encephalopathy, or preexisting cardiac disease. Finally, in non-transplant candidates, peritoneovenous shunting may be considered after failure of total paracentesis or contraindications to TIPS.
