Supplemental Data Content to 'A nationwide analysis of gallbladder surgery in England between 2000 and 2019'

This is the supplementary material for the paper titled “A nationwide analysis of gallbladder surgery in England between 2000 and 2019”. We aimed to generate a reliable report on four gallbladder surgeries – cholecystolithotomy, cholecystostomy, subtotal cholecystectomy and total cholecystectomy – in England to allow cross-procedure comparisons and highlight changes in the management of benign gallbladder disease over time. It adheres to the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement and checklist. This analysis provides valuable insights into gallbladder surgery in England and highlights a significant shift towards the increased utilization of subtotal cholecystectomy and cholecystostomy in England between 2000 and 2019.

This supplement for the Mendeley repository provides further details to reproduce the study results. It is organized into sections that follow the structure of the article. It contains a synopsis of the study and explains our research in context. It provides the key messages, 16 tables (including the STROBE checklist) and ten figures.
