Gallbladder cancer (GBC) is associated with GBPs but the risk of malignancy is low. International guidelines recommend ultrasound surveillance (USS) in selected cases of GBPs <10 mm, with cholecystectomy advised if the polyp size increases. USS (including potential cholecystectomies) is resource intense. We evaluated the costs and potential cost-effectiveness of USS in a theoretical UK patient cohort with GBPs.</p><p><strong>Methods: </strong>A health economic model mapped expected management pathways over 2 years for 1000 GBP patients with and without USS, stratified by the initial size of GBP (<6 mm and 6-9 mm). We estimated USS resource and costs under alternate referral thresholds for cholecystectomy. Clinical data were extracted from a large-scale cohort study. TAUS and cholecystectomy costs were based on NHS tariffs. GBC costs were estimated from the literature. Outcomes included USS costs, expected numbers of GBC, and incremental cost for each case of GBC avoided.</p><p><strong>Results: </strong>The 2-year additional cohort costs of USS (n = number of cholecystectomies) were estimated between £213 441 (n = 50) and £750 045 (n = 253) in GBPs <6 mm and between £420 275 (n = 165) and £531 297 (n = 207) in GBPs 6-9 mm, balanced against avoidance of 1.3 (<6 mm) and 8.7 (6-9 mm) cases of GBC.
