My gallbladder wall measures 9ml do i need to have it removed?

Consult your doctor: Nine millimeter gallbladder wall appears unusally thick. Pathology examination may be needed to determine the nature of your gallbladder condition.

9 mm?: Do you mean 9 millimeters? If so the gallbladder should be removed as it is likely chronically inflamed. Top normal size in a contracted gallbladder is 7 mm, the size can vary depending on how recently you have eaten, but 9 mm is definitely abnormal. See a surgeon for evaluation.
