A Modified Technique to Facilitate Anastomosis in Choledochal Cyst

The method of choice for the treatment of choledochal cysts in children is excision of the cyst and Roux-en-Y (RY) choledochoenterostomy. When the ratio of the diameter of the main hepatic ductus to that of the proximal RY jejunum is 1:2.5 or lower during choledochoenterostomy, end-to-end anastomosis is recommended. However, this method may cause a difference in diameters between the ends. Here we will present the technical difficulty we experienced due to the difference in diameters in end-to-end RY choledochoenterostomy and our modified anastomosis technique of anas¬tomosis. This slight modification eliminated problems with anastomosis caused by a difference in the diameter of the jejunum and shortened operation time.
