Core Tip
Core tip: Polypoid lesions of the gallbladder (PLGs) are commonly encountered in clinical practice. This study investigated the prevalence and risk factors of PLGs in a cohort of petrochemical employees in the city of Ningbo, Zhejiang Province, China. It was demonstrated that 7.4% of the petrol-chemical employees studied had PLGs; and male, hepatitis B surface antigen positive and middle-aged employees, especially those aged between 30 and 59 years, had higher risks for developing PLGs.
