Backgrounds/Aims: To investigate if the increase in the number of cholecystectomies is proportional to symptomatic gallbladder-associated hospital admissions in Australia and Aotearoa New Zealand (NZ).
Methods: National healthcare registries were used to obtain data on all episodes of cholecystectomies and hospital admissions for patients ≥ 15 years from public and private hospitals.
Results: Between 2004 and 2019, in Australia, there have been 1,074,747 hospital admissions and 779,917 cholecystectomies, 715,462 (91.7%) of which were laparoscopic, and 163,084 admissions and 98,294 cholecystectomies in NZ. The 15?54 years age group saw an increase in operative rates, +4.0% in Australia and +6.6% in NZ, and admissions, +3.7% and +5.8%, respectively. Hospital admissions decreased by ?9.8% in Australia but the proportion of patients undergoing intervention increased by 10.8% (from 67.1% to 75.0% of hospital admissions). Procedural rates increased by +7.3% in NZ with no change in the intervention rate.
Conclusions: In Australia, there has been a decline in symptomatic gallbladder-associated hospital admissions and a rise in intervention rate. Admissions and interventions have increased proportionally in NZ. There are higher rates of cholecystectomy and admission amongst younger demographics, compared to historical cohorts. Future research should focus on identifying risk factors for increased disease and operative rates amongst younger populations.
