Hello - thanks for asking your question.
You state bloating and gas. An ultrasound was negative. HIDA scan showed a 10% gallbladder ejection fraction. Pain is worse in the left lower quadrant with occasional right sided pain.
There are several possibilities. The first would be acalculous (i.e. non-gallstone related) biliary pain. Nausea and vomiting is common with this and an ultrasound would not show any gallstones. In people with normal gallbladders, the ejection fraction ranges between 35-75 percent. Patients who suffer from bouts of biliary pain and have lower ejection fraction readings are assumed to have ABP. Studies have shown that surgical removal of the gallbladder (cholecystectomy) helps ABP patients more than 90 percent of the time.
Other considerations would be dyspepsia (peptic ulcers, GERD, gastritis/esophagitis), pancreatitis, or a mass. An upper endoscopy may be considered to evaluate for this. Serum tests for amylase and lipise would help evaluate the pancreas.
If you are having left lower quadrant pain, then the causes would include irritable bowel, diverticulitis, colorectal mass, or inflammatory bowel. To evaluate this, colonoscopy and/or abdominal CT would be helpful.
If your gall bladder ejection fraction is only 10%, you will be prone to further gall bladder attacks in the future. Cholecystectomy has been shown to help in a majority of cases. If you and your physician elects to keep searching for other causes, the tests I mentioned above may be considered.
Followup with your personal physician is essential.
