Decision for surgery in the management of a rare condition, childhood gallbladder polyps, and the role of ultrasonography.

[achondroplasia]

Gallbladder polyps are tumors or tumor -like protrusions of the gallbladder . They are rarely seen in the pediatric age . Most important issue about these mostly incidental lesions is the risk of malignant transformation . Size more than 10 mm is the classicalcutoff for determining this risk , but it is rarely valid in children . Ultrasonography is the method of choice for follow-up , but it rarely demonstrates change of size or malignant transformation . Hereby , we report 6 cases of childhood gallbladder polyps , none of which had a genetic risk factor . Follow-up was uneventful in 4 of them . Two patients had undergone surgery , but none of the lesions were neoplastic . In the follow-up , a single experienced radiologist should handle the patient , in order to prevent inter-observer variation . The cut-off size for deciding surgery should be 10 mm for those cases with genetic background creating malignancy risk (metachromatic leukodystrophy , pancreaticobiliary duct abnormalities , achondroplasia , Peutz-Jeghers syndrome ) or with accompanying cholelithiasis , and 15 mm for those without any risk factors to prevent any unnecessary operations .
