Poor outcome from peritoneovenous shunts for refractory ascites

Area of Science:

• Hepatology
• Gastroenterology
• Surgical Interventions

Background:

• Refractory ascites is a common complication of advanced chronic liver disease.
• Peritoneovenous shunts were historically used to manage refractory ascites.
• Limited data exists on the long-term outcomes and complications of these shunts.

Purpose of the Study:

• To evaluate the morbidity and mortality associated with peritoneovenous shunt placement in patients with refractory ascites.
• To identify risk factors for poor outcomes in patients receiving peritoneovenous shunts.

Main Methods:

• Retrospective review of patient records from 1977-1986.
• Inclusion criteria: patients with refractory ascites due to chronic liver disease undergoing peritoneovenous shunt placement.
• Data collected included liver disease etiology, Child's classification, complications, and mortality.

Main Results:

• 23 patients received peritoneovenous shunts; alcoholic cirrhosis was the most common etiology.
• 14 of 23 patients experienced complications, including coagulopathy, infection, and hemorrhage.
• 15 of 23 patients died, with 8 deaths potentially related to shunt placement (sepsis, hepatorenal syndrome, coagulopathy, pulmonary edema).
• All Child's class C patients and those with high bilirubin levels died within one month of hospitalization.

Conclusions:

• Peritoneovenous shunt placement for refractory ascites is associated with high morbidity and mortality in patients with advanced liver disease.
• The risks associated with peritoneovenous shunts outweigh potential benefits in this patient population.
• Current evidence does not support the use of peritoneovenous shunts for managing refractory ascites in advanced liver disease.
