OBJECTIVE. The objective of our study was to evaluate the efficacy and safety of balloon dilatation in the treatment of anastomotic strictures in children with liver transplants. MATERIALS AND METHODS. For a period of 7 years, we treated 20 consectutive biliary-enteric strictures in 19 children (age range. 13 months to 17.9 years, mean, 73 years) with balloon dilatation. Dilatation was performed between 30 days and 8.4 years (mean, 2.6 years) following surgical creation of the biliary-enteric anastomosis. Thirteen patients had left lateral segment liver transplant grafts, one patient had a split-liver, left-lobe graft, and five patients had whole liver grafts. RESULTS. Technical success was 100%, and there were no procedure-related complications. One patient with a patent anastomosis underwent repeat transplantation 183 days after the procedure for chronic rejection. In 58%, (11/19) of the remaining procedures, balloon dilatation resulted in biliary-enteric patency at one year. and continued patency range from 1.41 to 5.4 years (mean, 3.6 years). In 40% (8/20) of the procedures, the biliary-enteric structure persisted after balloon dilatation, and these patients eventually underwent surgical revision, retransplantation, or endobiliary metallic stent placement. CONCLUSION. Balloon dilatation is a safe and effective treatment for biliary-enteric strictures following pediatric liver transplantation.
