Portoenterostomy
Pronunciation: por-toe-en-ter-OSS-toe-me
Surgical anastomosis between the porta hepatis and small bowel to restore bile drainage. Primary treatment for biliary atresia.
Full Definition
Portoenterostomy is a reconstructive surgical procedure that creates a direct connection between the porta hepatis (the area where vessels and ducts enter and exit the liver) and a segment of small intestine, typically jejunum. This procedure bypasses obstructed or absent bile ducts to restore bile drainage from the liver to the intestinal tract. It is most commonly performed as the Kasai portoenterostomy for biliary atresia, where the extrahepatic bile ducts are absent or obliterated. Success depends on the presence of patent intrahepatic bile ducts and performing the procedure before irreversible liver damage occurs.
Usage
Usage note: Distinguish from other hepatobiliary anastomoses by specifying the anatomical connections involved.
