I have been having GI problems for about a yr, lots of gas, nausea, indigestion, epigastric ache at times, just left of center. Starts within an hr or so of eating. No right sided pain or discomfort. Ultrasound negative for stones, normal upper and lower endoscopy, meds for IBS do not work. Currently taking Lansoprazole for reflux, but does not help much. No diarrhea, maybe some constipation. Got worse over past yr. Fatty meals do seem to make things a bit worse. GP orders Hida scan and ejection fraction was 22%. Hida scan did reproduce many of the symptoms, but they occured about 15 min after the scan was completed. So I have decided to go for the laparoscopy to have gallbladder removed. So perhaps I am second guessing myself but does this sound like a good decision? Concerned on how accurate these hida scans are at diagnosing, esp since I do not have right side issues and no stones visible on ultrasound.
