The global incidence of benign biliary tract diseases is high. Not only its anatomical variations are complex and the disease heterogeneity is strong, but also its preoperative assessment methods, surgical techniques and diagnostic and treatment strategies need to be improved. Consequently, patients have many perioperative complications and a poor long-term prognosis. According to the anatomical characteristics of the biliary tract and the pathophysiological characteristics of benign biliary diseases, we propose the surgical treatment concept of benign biliary tract diseases with the removal of the diseased bile duct tree drainage as the core, which is different from the traditional biliary surgery that takes “patency and obstruction” as the focus of treatment, and “alleviates symptoms” as the treatment goal. Through a series of improvements such as preoperative evaluation, surgical planning, surgical operations, and postoperative management, we have designed a series of innovative diagnosis and treatment strategies and procedures with the goal of curing biliary diseases, with a view to changing the diagnosis and treatment status of biliary surgery. We hope that can change the current the diagnosis and treatment status of biliary surgery.
