Objective Questions remain about the association among cholecystectomy, cardiovascular disease, all-cause and cause-specific mortality. We performed a systematic review and meta-analysis to clarify these associations. Methods PubMed, Web of Science, Embase, and Cochrane Library databases were searched up to February 2024. Summary relative risks (RRs) and 95% confidence intervals (CIs) were calculated using a DerSimonian–Laird random effects model. Results We screened 16,595 articles and included 14 studies. No significant association was found between cholecystectomy and cardiovascular disease (CVD), with RR being 1.03 (95% CI [0.77–1.37], p = 0.848, I2 = 99.6%), even in results with high heterogenous studies excluded (RR 1.20, 95% CI [0.97–1.49], p = 0.095, I2 = 77.7%). Same result was proved in its subtype, coronary heart disease (RR 1.06, 95% CI [0.84–1.33], p = 0.633, I2 = 96.6%). Cholecystectomy increased CVD risk compared with healthy controls without gallstones (RR 1.19, 95% CI [1.05–1.35], p = 0.007, I2 = 83.3%) and lowered CVD risk compared with gallstone carriers (RR 0.62, 95% CI [0.57–0.67], p < 0.001, I2 = 82.1%). As for mortality, increase in the risk for all-cause (RR 1.17, 95% CI [1.03–1.34], p = 0.020, I2 = 51.6%) and cardiovascular (RR 1.24, 95% CI [1.06–1.47], p = 0.009, I2 = 20.7%) mortality, but not for cancer mortality (RR 1.18, 95% CI [0.95–1.47], p = 0.131, I2 = 0.0%), were observed after cholecystectomy. Conclusion Cholecystectomy may not be associated with the overall development of CVD, as well as CHD. Cholecystectomized patients showed increased CVD risk compared with healthy controls without gallstones, but decreased CVD risk compared with gallstone patients. Increased risk for all-cause and cardiovascular, but not cancer mortality was observed following cholecystectomy. |
