Transjugular intrahepatic portosystemic shunting versus paracentesis plus albumin for refractory ascites in cirrhosis. Randomized controlled study of TIPS versus paracentesis plus albumin in cirrhosis with severe ascites. The North American Study for the Treatment of Refractory Ascites. Transjugular intrahepatic portosystemic shunt versus sclerotherapy in the elective treatment of variceal hemorrhage. A comparison of paracentesis and transjugular intrahepatic portosystemic shunting in patients with ascites.
The transjugular intrahepatic portosystemic shunt (TIPS) has been shown to be more effective than repeated paracentesis plus albumin in the control of refractory ascites. However, its effect on survival and healthcare costs is still uncertain.
                Seventy patients with cirrhosis and refractory ascites were randomly assigned to TIPS (35 patients) or repeated paracentesis plus intravenous albumin (35 patients). The primary endpoint was survival without liver transplantation. Secondary endpoints were complications of cirrhosis and costs.
                Twenty patients treated with TIPS and 18 treated with paracentesis died during the study period, whereas 7 patients in each group underwent liver transplantation (mean follow-up 282 +/- 43 vs. 325 +/- 61 days, respectively). The probability of survival without liver transplantation was 41% at 1 year and 26% at 2 years in the TIPS group, as compared with 35% and 30% in the paracentesis group (P = 0.51). In a multivariate analysis, only baseline blood urea nitrogen levels and Child-Pugh score were independently associated with survival. Recurrence of ascites and development of hepatorenal syndrome were lower in the TIPS group compared with the paracentesis group, whereas the frequency of severe hepatic encephalopathy was greater in the TIPS group. The calculated costs were higher in the TIPS group than in the paracentesis group.
                In patients with refractory ascites, TIPS lowers the rate of ascites recurrence and the risk of developing hepatorenal syndrome. However, TIPS does not improve survival and is associated with an increased frequency of severe encephalopathy and higher costs compared with repeated paracentesis plus albumin. The transjugular intrahepatic portosystemic shunt (TIPS) has been shown to be effective in the control of refractory or recidivant ascites. However, the effect of TIPS on survival as compared with that of large-volume paracentesis plus albumin is uncertain. A multicenter, prospective, clinical trial was performed in 66 patients with cirrhosis and refractory or recidivant ascites (16 Child-Turcotte-Pugh class B and 50 Child-Turcotte-Pugh class C) randomly assigned to treatment with TIPS (n = 33) or with large-volume paracentesis plus human albumin (n = 33). The primary endpoint was survival without liver transplantation. Secondary endpoints were treatment failure, rehospitalization, and occurrence of complications. Thirteen patients treated with TIPS and 20 patients treated with paracentesis died during the study period, 4 patients in each group underwent liver transplantation. The probability of survival without transplantation was 77% at 1 year and 59% at 2 years in the TIPS group as compared with 52% and 29% in the paracentesis group (P = .021). In a multivariate analysis, treatment with paracentesis and higher MELD score showed to independently predict death. Treatment failure was more frequent in patients assigned to paracentesis, whereas severe episodes of hepatic encephalopathy occurred more frequently in patients assigned to TIPS. The number and duration of rehospitalizations were similar in the two groups. In conclusion, compared to large-volume paracentesis plus albumin, TIPS improves survival without liver transplantation in patients with refractory or recidivant ascites.
                Copyright 2004 American Association for the Study of Liver Diseases The clinical utility of transjugular intrahepatic portosystemic shunts (TIPS) vis-à-vis total paracentesis in the management of refractory ascites is unclear.
                A multicenter, prospective, randomized clinical trial was performed in which 109 subjects with refractory ascites were randomized to either medical therapy (sodium restriction, diuretics, and total paracentesis) (n = 57) or medical therapy plus TIPS (n = 52). The principal end points were recurrence of tense symptomatic ascites and mortality.
                A technically adequate shunt was created in 49 of 52 subjects. TIPS plus medical therapy was significantly superior to medical therapy alone in preventing recurrence of ascites (P < 0.001). The total number of deaths in the 2 groups was identical (TIPS vs. medical therapy alone: 21 vs. 21). There were no significant differences in the 2 arms with respect to overall and transplant-free survival. There was a higher incidence of moderate to severe encephalopathy in the TIPS group (20 of 52 vs. 12 of 57; P = 0.058). There were no significant differences in the number of subjects who developed liver failure (7 vs. 3), variceal hemorrhage (5 vs. 8), or acute renal failure (3 vs. 2). There were also no significant differences between the 2 groups in the frequency of emergency-department visits, medically indicated hospitalizations, or quality of life.
                Although TIPS plus medical therapy is superior to medical therapy alone for the control of ascites, it does not improve survival, affect hospitalization rates, or improve quality of life. Uncontrolled studies suggest that placement of a transjugular intrahepatic portosystemic shunt (TIPS) could be useful in the treatment of variceal bleeding. The aim of this study was to evaluate the efficacy and safety of TIPS in the elective treatment of hemorrhage from esophageal varices in a randomized controlled study that compared the effects of TIPS with those of endoscopic sclerotherapy (ES).
                Sixty-three consecutive cirrhotic patients with hemorrhage from esophageal varices were included. Thirty-two patients were randomly allocated to ES and 31 to TIPS groups.
                One patient in each group died before the therapeutic procedure could be performed. During a mean follow-up period of 15 months, variceal rebleeding occurred in 51.6% of the patients in the ES group and 23% of those in the TIPS group. Uncontrolled rebleeding occurred in 10 of 31 patients in the ES group, whereas rebleeding did not occur in any patient of the TIPS group. Hepatic encephalopathy was more frequent in TIPS patients (33.3%) than in those treated by ES (13%). However, mortality was similar in both treatment groups.
                These preliminary results suggest that TIPS is more effective than ES in the prevention of variceal rebleeding in cirrhotic patients, even though no difference in survival was observed. In patients with cirrhosis and ascites, creation of a transjugular intrahepatic portosystemic shunt may reduce the ascites and improve renal function. However, the benefit of this procedure as compared with that of large-volume paracentesis is uncertain.
                We randomly assigned 60 patients with cirrhosis and refractory or recurrent ascites (Child-Pugh class B in 42 patients and class C in 18 patients) to treatment with a transjugular shunt (29 patients) or large-volume paracentesis (31 patients). The mean (+/-SD) duration of follow-up was 45+/-16 months among those assigned to shunting and 44+/-18 months among those assigned to paracentesis. The primary outcome was survival without liver transplantation.
                Among the patients in the shunt group, 15 died and 1 underwent liver transplantation during the study period, as compared with 23 patients and 2 patients, respectively, in the paracentesis group. The probability of survival without liver transplantation was 69 percent at one year and 58 percent at two years in the shunt group, as compared with 52 percent and 32 percent in the paracentesis group (P=0.11 for the overall comparison, by the log-rank test). In a multivariate analysis, treatment with transjugular shunting was independently associated with survival without the need for transplantation (P=0.02). At three months, 61 percent of the patients in the shunt group and 18 percent of those in the paracentesis group had no ascites (P=0.006). The frequency of hepatic encephalopathy was similar in the two groups. Of the patients assigned to paracentesis in whom this procedure was unsuccessful, 10 received a transjugular shunt a mean of 5.5+/-4 months after randomization; 4 had a response to this rescue treatment.
                In comparison with large-volume paracentesis, the creation of a transjugular intrahepatic portosystemic shunt can improve the chance of survival without liver transplantation in patients with refractory or recurrent ascites.
The meta-analysis supports that TIPS was more effective at removing ascites as compared with paracentesis without a significant difference in mortality, gastrointestinal bleeding, infection, and acute renal failure. However, TIPS patients develop hepatic encephalopathy significantly more often.
