Upper GI bleed: varices: TIPS reduced variceal rebleeding better than sclerotherapy.

Clinical bottom line (level 1b)

  1. Patients with cirrhosis and severe bleeding from oesophageal varices who received TIPS compared with endoscopic sclerotherapy, were less likely to rebleed from their varices (NNT = 3 at 1.5 years) .
  2. There was no clear effect on mortality or development of encephalopathy.

The study

Unblinded ?concealed randomised trial with intention-to-treat
Setting: three teaching hospitals, USA

49 patients (aged range 34 to 73 years; mean 47, 73% male) cirrhosis and massive or submassive bleeding (systolic blood pressure <80 mmHg, or postural vital signs changes) from endoscopically-documented bleeding oesophageal varices (>1 cm diameter with cherry red spots, haematocystic spots or red wale sign)

Excluded if
  • prisoners
  • aged <18 or >75
  • refused blood products
  • gastric variceal bleeding
  • MI on ECG, or CVA within three months
  • pO2 <70 mmHg, pH <7.2, creatinine >221 µ mol/l PTT >5s of control after FFP, bilirubin >7 mg/dl or platelets <50 x10 9 /l
  • cancer
  • HIV, sepsis, pneumonia or peritonitis
  • alcoholic hepatitis, stage IV encephalopathy
  • thrombosis of portal, hepatic or inferior vena cava on doppler ultrasound

Control Group: (n = 25, 25 analysed): repeated sclerotherapy every 2 to 7 days in hospital, then weekly with ethanolamine oleate
Experimental Group: (n = 24, 24 analysed): transjugular intrahepatic portosystemic shunt inserted within 48 hours of randomisation (stent used, target portal to hepatic vein pressure gradient of 12 mmHg or less achieved in all cases). After stenting, persisting varices were occluded with embolisation coils.
All patients received endoscopic sclerotherapy at the initial session.
100% followed for 1.5 years
Outcome notes:
  • new or worsening encephalopathy : asterixis, disorientation, agitation, somnolence or coma

  • Patients in the TIPS group had higher pre-treatment transfusion requirements and worse Pugh scores (9 v 7.8).
  • Six patients given sclerotherapy crossed to TIPS for control of bleeding. One TIPS patient crossed to sclerotherapy for technical failure.
  • 18% of TIPS stents were occluded and required angioplasty.
  • Health care costs were similar (~$28, 000).
  • Comments

    1. The study is too small to demonstrate any effect on mortality or encephalopathy.
    2. Likewise, the study was not large enough to show any difference in the number of GI bleeds from any source, nor in transfusion requirements.
    3. There was no difference in the incidence of encephalopathy, BUT this was not assessed blind and was based on clinical judgement alone. However, a review of six earlier studies shows significant reduction in variceal bleeding at the cost of increased encephalopathy without an improved survival.
    4. TIPS is primarily used as a rescue therapy
