Abstract: Based on current diagnosis and treatment of gallbladder disease, the occur-rence of incidental gallbladder cancer is partly caused by the irregular clinical diagnosis and treatment process of gallbladder disease, which leads to the failure to make the diagnosis of gallbladder cancer in time, carry out the correct preoperative and intraoperative staging, and cause R₁ or R₂ resection. The authors summarize standardized diagnosis and treatment process of gallbladder disease and technical details. In clinical practice, the concept of incidental gallbladder cancer should be discarded, and various gallbladder diseases should be taken as a whole. A more standardized diagnosis and treatment process should be established to improve the diagnostic accuracy of gallbladder cancer and achieve radical resection, which eventually improve survival of patients.
