Gallbladder polyps are growths on the gallbladder wall, detected via abdominal sonography or histopathology, with a prevalence of up to 9.5%. They are immobile, lack posterior acoustic shadowing, and can be sessile or pedunculated. Polyps are classified as pseudopolyps (benign) or true polyps (benign or malignant). Pseudopolyps include cholesterolosis and inflammatory types, while true polyps can be benign (e.g., adenomas) or malignant (e.g., adenocarcinomas). Ultrasound is the preferred diagnostic method, crucial for managing gallbladder polyps and reducing unnecessary further investigations and surgeries.
