I have mild pain and several small stones in my gall bladder, with a hida scan ejection rate of 71%. do i still need to have my gallbladder removed?

No...: You don't have acute cholecystitis which would warrant having your gallbladder removed. Your symptoms sound mild and perhaps could be debated if caused by the tiny stones in your gallbladder in the first place. There is no risk in waiting, so i suggest not going for surgery unless your symptoms worsen and all other possible causes have been ruled out.

Yes you need: You do have symptoms even though it is not acute cholecystitis , small stones can move into bile ducts, could cause dangerous bile stone pancreatitis , or bile duct obstruction & jaundice, elective simple gb removal , which is a same day surgery , will prevent the future need less complications

Possibly: Depending the rest of your work-up, probably yes. If your evaluation and resultant diagnosis is symptomatic cholelithiasis, you should have cholecystectomy. These links may assist: http://goo.Gl/6iiah and http://goo.Gl/1c7et.

Probably so: If these pain symptoms are thought to be due to your gallstones, your gallbladder should be removed to prevent complications like choledocholithiasis (stones in main bile ducts), acute cholecystitis and gallstone pancreatitis. A normal hida ejection fraction does not change that.

Probably: High ejection fraction can cause gb symptoms not dissimilar to when the ejection fraction is low. If you symptoms are associated with eating or eating certain types of food, i think that having your gb removed will help.
