    Abstract:
    Sixteen children (3.5-14.7 years) with portal hypertension and variceal hemorrhage were treated by direct endoscopic variceal sclerotherapy. Follow-up clinical and endoscopic evaluations have been carried out over a 1-6-year period (mean, 2.3 years). Prior to sclerotherapy, three patients had undergone unsuccessful surgical approaches, and the mean transfusional requirement from the time of the first hemorrhage was 12.3 units of blood per child per year for those with extrahepatic portal vein obstruction (n = 10) and 3.8 units for those with primary liver disease. Following sclerotherapy, transfusional requirements were significantly reduced in both groups, to 1.8 units and 2.2 units (85% and 43% reduction, respectively). Re-bleeding in four patients was due to the occurrence of gastric varices. One patient with extrahepatic portal hypertension has required subsequent shunt surgery for this complication, 5 years after sclerotherapy. Two patients have died, one with cystic fibrosis and hemorrhage from gastric varices and one from liver failure due to progressive biliary cirrhosis. Complications of sclerotherapy included transient retrosternal pain (eight occasions), esophageal ulceration with bleeding (n = 1) and esophageal stricture (n = 1). We conclude that sclerotherapy is an effective technique in obliterating esophageal varices and reducing the risk of hemorrhage in children with portal hypertension, with an acceptably low complication rate. We favor its use over more invasive surgical measures for control of acute and recurrent variceal hemorrhage, particularly for cases of extrahepatic portal hypertension in which a favorable natural history is likely.
