When these nonsurgical interventions fail, surgical re\u2010anastomosis is considered; however, this is quite invasive and can cause additional injury that may lead to graft loss. We report a case in which conventional nonsurgical interventions failed, but a new method that involve the use of a transseptal needle\u2014a device to create a transseptal left\u2010heart access during cardiac catheter interventions\u2014was successfully used in recanalization of the hepaticojejunal anastomotic obstruction.<\/jats:p><\/jats:sec><jats:sec><jats:title>Case<\/jats:title><jats:p>A 21\u2010year\u2010old man, who had received living\u2010donor liver transplantation for biliary atresia at the age of 23\u00a0months presented with recurrent cholangitis and liver dysfunction due to a biliary anastomotic stricture of the hepaticojejunostomy. Therapeutic interventions for biliary stricture, including the PTB approach, double\u2010balloon enteroscopic approach, and rendezvous approach failed. We then performed needle puncture of the anastomotic obstruction using a transseptal needle and succeeded in recanalizing the complete anastomotic obstruction. To perform the procedures safely, we evaluated the organ and needle positions using biplane fluoroscopy and placed a balloon in the afferent jejunal limb as a target for puncture. The 12 Fr catheter via the biliary route was removed 7\u00a0months after the procedure, without using a catheter, there was no recurrent stricture or cholangitis for 26\u00a0months.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Using a transseptal needle to manage hepaticojejunal anastomotic obstruction can reduce the number of
