Risk factors for gallbladder Cancer:A meta-analysis based on nearly a decade of research

Review question / Objective: Gallbladder cancer is a rare tumor that is mostly advanced once detected. The efficacy of surgical treatment is still controversial. Therefore, primary prevention of gallbladder cancer is important. There are many studies on risk factors for gallbladder cancer, but at present it is difficult to identify independent risk factors for gallbladder cancer, except for a history of symptomatic chronic cholecystitis and malignant transformation of a single polyp. Laparoscopic cholecystectomy is popular worldwide and can be a preventive procedure for gallbladder cancer in addition to resolving benign lesions. This study makes a meta-analysis of the latest research results exploring the risk factors of gallbladder cancer in the last decade , expecting to provide evidence-based medical support for the prevention of gallbladder cancer at the clinical level, and to provide some ideas to guide the surgical indications for LC and future research related to gallbladder cancer. Subject of study: Gallbladder cancer. Study content: Risk factors. Type of study: case-control or cohort study. Extract the value: OR, HR, RR.
