RESUMO
INTRODUCTION: Data is currently lacking regarding association between the cholecystectomy/hepatectomy/pancreatectomy and the development of osteoporotic fracture. A retrospective cohort study was conducted to investigate the relationship between cholecystectomy/hepatectomy/pancreatectomy and the subsequent risk of developing osteoporotic fracture. MATERIALS AND METHODS: Patients having undergone cholecystectomy, hepatectomy, or pancreatectomy between 2000 and 2012 were selected from the All Population Based Hospitalization File as the surgery cohort (n = 304,081), which was frequency matched with the control cohort (n = 304,081). The Cox proportional hazard model and Kaplan-Meier analysis were applied to measure the hazard ratios and the cumulative incidence of osteoporotic fracture. RESULTS: A total of 1136 patients in the surgery cohort and 1179 patients in the control cohort were newly diagnosed with osteoporotic fracture. The overall osteoporotic fracture risk in the surgery cohort was 1.12-fold higher [95% confidence interval (CI), 1.03-1.21]. Specifically, surgery cohort had higher vertebral fracture risk than non-surgery cohort [adjusted hazard ratio (aHR) 1.12, Cl, 1.03-1.22]. In addition, patients underwent cholecystectomy (includes open and laparoscopic approaches), hepatectomy (only open approach), and pancreatectomy group (only open approach) were 1.10 (95% CI, 1.01-1.19), 1.49 (95% CI, 1.10-2.01), and 1.88 (95% CI, 1.23-2.87) times more likely to develop osteoporotic fracture, respectively. No significant difference of osteoporotic fracture risk was observed between open and laparoscopic cholecystectomy. The risk of osteoporotic fracture was significantly increased in females, patients aged ≥ 40 years old, and patients with some comorbidity. CONCLUSIONS: Patients post cholecystectomy, hepatectomy, or pancreatectomy significantly increased risk of developing osteoporotic fracture, suggesting closer attention in post-operative care is needed.
