An approach to managing gallbladder polyps for the general practitioner

Gallbladder polyps are increasingly being identified due to the widespread use of abdominal ultrasound imaging. They are concerning lesions due to their potential malignant risk. It is hoped that managing them correctly will play a role in improving poor survival rates of gallbladder cancer. Awareness of these lesions is lacking. Management continues to be guided by expert opinion and observational studies and a number of consensus statements exist.

This paper reviews and summarises the current literature and provides an approach for general practitioners based on the available guidance.

Although minor variation exists between consensus statements, the risk of malignancy for gallbladder polyps is still largely dictated by size, with those ≤5 mm generally considered to pose little risk and not requiring follow-up, whereas those ≥10 mm considered at greater risk and requiring referral for cholecystectomy.
