Hello - thanks for asking your question.
A biliary ejection fraction of lower than 35% is considered abnormal. In some cases, this may be associated with Sphincter of Oddi dysfunction (SOD). In any case, a low biliary ejection fraction predisposes you for gallstone formation in the future. The decision for a cholecystectomy should be made in conjuction with your personal gastroenterologist and surgeon.
Other causes of right upper quadrant pain includes hepatitis, cholecystitis, cholangitis, pancreatitis, pneumonia, sub-diaphragmatic abscess or peptic ulcer disease/gastritis. It is apparent you have undergone a battery of GI tests.
If you are passing greasy stools, perhaps tests for malabsorption (i.e. tests for fecal fat) may be in order.
You may also want to consider tests for non-GI causes of pain - for instance CT imaging for abscesses or an abdominal aneurysm.
There is also something known as painful rib syndrome that may be considered. The painful rib syndrome is an increasingly common condition characterized by discomfort in the lower chest or upper abdomen, tenderness over the costal margins, and reproduction of the pain by pressure on the ribs. This syndrome accounts for as many as 3 percent of new referrals to surgeons for the evaluation of upper abdominal pain. It is most common in women. The syndrome has a benign outcome and is important to recognize and diagnose to avoid unnecessary testing and treatment and to provide reassurance to the patient. In one review, 8 of 76 patients underwent noncurative cholecystectomy.
From a Department of Defense study, it was suggested that the cost of a laparoscopic cholecystectomy was $3959:

I strongly suggest that you continue to follow up with your personal physician.
I stress that this answer is not intended as and does not substitute for medical advice - please see your personal physician for further evaluation of your individual case.
Thanks,
