portoenterostomy

 [por″to-en″ter-os´tah-me]
surgical anastomosis of the jejunum to a decapsulated area of liver in the porta hepatis region, and to the duodenum; done to establish a conduit from the intrahepatic bile ducts to the intestine in biliary atresia.

por·to·en·ter·os·to·my

(pōr'tō-en'tĕr-os'tŏ-mē),
An operation for biliary atresia in which a Roux-en-Y loop of jejunum is anastomosed to the hepatic end of the divided extravascular portal structures, including rudimentary bile ducts.
Synonym(s): Kasai operation

n.
A surgical procedure for the treatment of biliary atresia in which a Roux-en-Y loop of the jejunum is anastomosed to the hepatic end of the divided extravascular portal structures, including the rudimentary bile ducts.

portoenterostomy

[pôr′tō·en′təros′təmē]
Etymology: L, porta + Gk, enteron, bowel, stoma, mouth, temnein, to cut
construction of a bile drainage system with an intestinal conduit to correct biliary atresia. There are several procedural approaches, such as anastomosis of the jejunum by a Roux-en-Y loop to the portal fissure region to establish bile flow from the bile ducts to the intestine. The procedure is indicated in patients younger than 3 months of age. The operation is successful in most cases, but in a significant number of patients late mortality occurs because of chronic medical problems. Without the operation, biliary cirrhosis develops with an attendant early death. Also called Kasai operation.
