Ultrasound showed poorly distended gallbladder & hida scan showed 0%ef. what does this mean?. food causes slight pain. will i need surgery?

Gallbladder problem: Your studies and your symptoms show that your gallbladder is not working well. In addition to the risk of having attacks of pain, there is a risk of more serious infection of the gallbladder (acute cholecystitis). Surgery to remove the gallbladder now is optional, but it's much easier and lower risk to remove it now, compared to after it turns into a bigger problem.
