ABSTRACT
BACKGROUND/

AIMS:

Gallstone disease (GSD) is a common gastrointestinal disorder. Clinical epidemiological studies revealed that alcohol consumption has a preventive effect on the development of GSD. This study aimed to evaluate the relative risks of drinking for GSD development and investigate the dose-response relationships.

METHODS:

A systematic search of the MEDLINE, EMBASE, and Cochrane Library databases for studies published up to 2018 was performed. All studies that satisfied the following eligibility criteria were included patients with GSD with or without cholecystitis; and cohort or case-control studies investigating the association between alcohol consumption and GSD development.

RESULTS:

Sixteen case-control studies including 24,401 gallstone cases and 76,185 controls, and eight cohort studies with 14,693 GSD cases among 2,432,471 person-years were enrolled. Alcohol consumption presented a decreased overall risk of GSD (pooled relative ratio [RR], 0.84; 95% confidence interval [CI], 0.79 to 0.89; p=0.02). Subgroup analyses according to drinking levels indicated a gradual risk reduction for GSD compared to nondrinkers (light RR, 0.96; 95% CI, 0.94 to 0.99; p=0.75; moderate RR, 0.80; 95% CI, 0.75 to 0.85; p=0.27; high RR, 0.66; 95% CI, 0.56 to 0.79; p < 0.01). A nonlinear risk reduction was observed in a dose-response meta-analysis of all the studies (n=14, p < 0.01 for nonlinearity).

CONCLUSIONS:

In this systematic review with meta-analysis, alcohol consumption could decrease the risk of GSD, and the dose-response analysis revealed a dose-dependent linear risk reduction and a weakened linear trend between alcohol consumption levels less than and greater than 28 g/day.
