Discrepancy in HIDA scan results
In May of 2019 I had a HIDA scan due to upper right abdominal pain, diarrhea, weight loss, etc. My scan showed gallbladder function at 3%. Surgeon suggested a CT scan as well (due to weight loss) which found a tumor in my large intestine. In June 2019 I had right colon resection to remove the tumor, but not my gallbladder. Tumor turned out to be large B-cell Non-Hodgkin's lymphoma for which I received chemotherapy. Fast forward two years, fully healed and cancer free but I still have some upper right abdominal pain (though not as severe as before), abnormal and frequent bowel movements, and an inability to gain weight. I received a second HIDA scan August 2021 which showed gallbladder function at 61%!
How is it possible to have such a wide discrepancy of test results? I realize the tests are 2 1/2 years apart but, can the gallbladder heal itself? Doesn't seem likely and my doctor cant explain it. Should I still have my gallbladder removed or….?
Thanks in advance for any pertinent information.
