PATHOLOGY

Detailed explanation-1: -For polyps 6–9 mm in diameter without signs of malignancy, a new US is recommended after 6 months. If the does not show any significant changes a new US is recommended after another 12 months and if no changes is found than no further imaging studies are made.

Detailed explanation-2: -Small gallbladder polyps-less than 1/2 inch in diameter-are typically benign and, in most cases, don’t need to be treated. Gallbladder polyps larger than 1/2 inch in diameter have a greater likelihood of being or becoming malignant. Gallbladder polyps larger than 3/4 inch have a high probability of being malignant.

Detailed explanation-3: -True gallbladder polyps are rare and have the potential to become cancerous. These polyps typically measure 5–20 millimeters (mm) in diameter. Any that are larger than 1 cm are more likely to become cancerous.

Detailed explanation-4: -Their diameters may range from 2 to 20 mm. They may be accompanied by gallstones. Smok et al. reported the adenoma incidence rate as 0.09% in their series with 12.153 cholecystectomy cases.
