Abstract:	This article discusses polypoid lesions of the gallbladder, which affect approximately 5 percent of the adult population. Most affected individuals are asymptomatic, and their gallbladder polyps are detected during abdominal ultrasound performed for unrelated conditions. Although the majority of gallbladder polyps are benign, most commonly cholesterol polyps, malignant transformation (to cancer) is a concern. The differentiation between benign and malignant lesions can be challenging. Several features, including patient age, polyp size and number, and rapid growth of polyps, are important discriminating features between benign and malignant polyps. Based on the evidence highlighted in this article, the authors recommend resection in symptomatic patients, as well as in asymptomatic individuals over 50 years of age, or those whose polyps are solitary, greater than 10 millimeters in diameter, or associated with gallstones or polyp growth on serial ultrasonography. New imaging techniques, including endoscopic ultrasound and enhanced computed tomography (CT scan), may aid in the differential diagnosis of these lesions and permit better patient management. A brief patient care algorithm is provided. 3 figures. 3 tables. 66 references.
