Core Tip

Core Tip: This is a retrospective cross-sectional study evaluating relationship between gallbladder polyp (GBP) and various body compositions including body fat distribution by using data from routine health checkups. According to this study, only fatty liver was an independent risk factor for GBP among the body compositions; visceral obesity and sarcopenia were not associated with GBP. There was a dose-dependent relationship between GBP and fatty liver especially in the larger GBP group. The results of this study suggest that careful assessment of GBP using abdominal ultrasonography be considered in patients with severe fatty liver.
