Neoplastic polyps in gallbladder: a retrospective study to determine risk factors and treatment strategy for gallbladder polyps

Gallbladder polyps (GBPs) are lesions that project from the gallbladder wall into the lumen. The widespread use of abdominal imaging techniques has led to a dramatic increase in the diagnosis of GBP (1-4). GBPs are broadly classified as non-neoplastic and neoplastic polyps (5,6). Cholesterol polyps are the most common type of non-neoplastic polyps. Some of the benign neoplastic polyps such as adenomas are considered pre-malignant lesions. Adenomas constitute 10% of GBPs and are found in approximately 1% of cholecystectomy specimens (7)
