Operative management and outcomes of gallbladder cancer in Australia: a multi-institutional, retrospective, observational cohort analysis.

Background: Data on optimal extent of resection for various stages of gallbladder cancer are lacking. This study aims to evaluate disease-free (DFS) and overall survival (OS) after simple (SC) versus radical cholecystectomy (RC) for gallbladder cancer in the Australian context, and assesses factors associated with post-operative morbidity.

Methods: Multi-centre, retrospective cohort analysis including all gallbladder cancer patients who underwent resection across six Australian institutions between January 2010 and January 2020.
