Endoscopic Sclerotherapy for Esophageal Varices in Children with Extrahepatic Portal Venous Obstruction: A Follow‐Up Study

Abstract

Background:Results of treatment with endoscopic sclerotherapy for esophageal varices in children extrahepatic portal venous obstruction are limited.Methods:A prospective study was undertaken of fifty children (mean age, 7.4 ± 3.8 years; range, 4 months to 14 years) with esophageal variceal bleeding caused by extrahepatic portal venous obstruction (EHPVO) treated by repeated intravariceal endoscopic sclerotherapy (EST) at intervals of 2‐3 weeks until eradication (no varices on endoscopy).Results:Eradication of varices was achieved in 44 children (88%) with a mean of eight sessions per child. In six other cases, variceal grade decreased by 50% from the initial grades. Bleeding episodes at presentation were controlled in all of the children with first ET>. Over a mean follow‐up period of 19 months (range, 12‐36 months), a total of 15 episodes of rebleeding occurred in 13 children (26%) before the third session of EST and all were controlled with EST. Risk of rebleeding in children with eradicated varices (n = 44) significantly decreased from 0.2 episodes per month to nil after eradication. None of the children without eradicated varices had rebleeding. Thus, EST was successful in controlling rebleeding in all of the cases. Recurrence of varices was observed in five children (10%). None of our children either required surgery for EST failure or died.Conclusions:EST is a safe and effective nonsurgical mode of therapy in controlling esophageal variceal bleeding in children with EHPVO. Significant variceal bleeding did not occur during the relatively short follow‐up in this series.
