Verification of the Tokyo guidelines for acute cholangitis secondary to benign and malignant biliary obstruction: experience from a Chinese tertiary hospital.

Background: The lack of widely-accepted guidelines for acute cholangitis largely lags behind the progress in medical and surgical technology and science for the management of acute cholangitis. This study aimed to verify the Tokyo guidelines for the management of acute cholangitis and cholecystitis of 2007 edition (TG07) in patients with obstructive cholangitis due to benign and malignant diseases.

Methods: The patients were retrieved from our existing ERCP database.
