Laparoscopic Surgery of Congenital Biliary Dilatation
Laparoscopic surgery has become a common procedure for congenital biliary dilatation. The dilated choledochus should be removed completely just above the confluence of the common biliopancreatic channel at the distal end and approximately 5 mm from the confluence of the right and left hepatic ducts at the proximal end to avoid complications of the its remnant. The operation is feasible and safe. The rate of conversion to open surgery is low. The rate of complication of laparoscopic surgery performed by skilled surgeons is also low, even lower than that of open surgery. There is no difference between hepaticoduodenostomy and hepaticojejunostomy concerning the rate of cholangitis. Gastritis due to bilious reflux occurred with a low rate in hepaticoduodenostomy. Both techniques could be used for congenital biliary dilatation; however, hepaticoduodenostomy should be applied for congenital biliary dilatation without intrahepatic dilatation of biliary tract.
