Controversy on the Oddi Sphincter Function in the Treatment of Hepatolithiasis：Preservation Versus Deprivation / 中国微创外科杂志

[Summary] The controversy remains on whether the Oddi sphincter function should be preserved or deprived in the treatment of hepatolithiasis .The surgical approaches achieving both hepatobiliary lesions clearance and Oddi sphincter preservation have been widely accepted .The biliary-enterostomy is suspected to increase the risk of reflux cholangitis and cholangiocarcinoma due to iatrogenic Oddi sphincter deprivation.Endoscopic sphincterotomy (EST) as a minimally invasive method still needs further research to determine its role in hepatolithiasis management .
