Successful percutaneous transhepatic recanalization of a completely obstructed hepatico-jejunal anastomosis in a child with liver transplantation: Unusual employment of the transseptal puncture system.

Stenosis of the HJ is a common complication of pediatric split LT with high morbidity and possible evolution to secondary biliary cirrhosis and re-transplantation if not treated. Because the endoscopy is generally infeasible in the Roux-en-Y, percutaneous interventional radiology management is usually the safest and most effective approach to avoid surgical revision of a stenotic bilio-enteric anastomosis. We present the case of a child with acute onset of cholestasis 7 months after left lateral segment partial LT due to occlusion of the HJ. The biliary stricture was found to be non-crossable with conventional interventional radiological techniques. The obstruction was resolved creating a new bilio-digestive communication via percutaneous transhepatic approach using the TPS. This device is usually employed by the interventional cardiologist to perform some procedures requiring the direct access to the left atrium through interatrial septal puncture. In conclusion, percutaneous transhepatic recanalization of the hepato-jejuno anastomosis is a rare but feasible and valuable procedure alternative to the surgical resolution even in small infants. Although few cases have been reported in literature, it has to be considered an additional treatment option when the conventional approaches fail.
