A comparative study of emergency transjugular intrahepatic portosystemic stent-shunt and esophageal transection in the management of uncontrolled variceal hemorrhage.
OBJECTIVE
Transjugular intrahepatic portosystemic stent-shunts (TIPSS) have been shown to reduce portal hypertension consistently and have recently been reported to arrest active variceal hemorrhage. This retrospective and nonrandomized study compares the results of TIPSS with esophageal transection (ET) and devascularization in patients with uncontrolled variceal hemorrhage admitted to a single center with an interest in variceal bleeding.


METHODS
Two hundred and sixty cirrhotic patients have been referred with variceal bleeding over the past 7 yr. In 41 patients (15.8%), hemorrhage was uncontrolled despite two treatments with sclerotherapy. Thirty-eight patients were eligible for analysis. Nineteen were considered for ET and 19 for TIPSS. Patients in the two groups were well matched for age, sex, etiology of liver disease, and its severity and complications. They have been followed for 13 patient years (TIPSS-7, longest 20 months; ET-6, longest 23 months). Data for survival and rebleeding were analyzed by the Kaplan-Meier method on an intention-to-treat basis.


RESULTS
Seven of the 19 were considered unfit for surgery, and 12 underwent esophageal transection and devascularization. TIPSS was undertaken successfully in 17 patients, the Palmaz stent being used in 4 and the Wallstent in 13. Successful TIPSS reduced the mean portal pressure gradient from 22.2 (SE 1.2) to 9.7 (SE 0.7) mm Hg (p < 0.001). Mortality within 30 days of the initial bleed was 42% in the TIPSS group compared with 79% in the ET group (p < 0.05). Rebleeding occurred in 15.6% patients with TIPSS, compared with 26.2% in the ET group. Encephalopathy in the two groups of patients was not significantly different (TIPSS 25% and ET 22%). TIPSS was followed by active infection in 20% compared with 36% after ET.


CONCLUSIONS
This study shows that the overall mortality in this group of patients is high whatever the type of treatment used. TIPSS can be performed successfully on these patients who are often not suitable for surgery. Mortality rates were significantly lower in patients treated by TIPSS. Compared with ET, TIPSS should be regarded as the preferred mode of treatment for uncontrolled variceal hemorrhage in patients with cirrhosis.
