Thank you for the query.
It is very common that if the patient suffers from peptic ulcers, all tests(like blood work and ultrasound
) are negative. It is because stomach mucous is hardly visible for the ultrasound.
You have not mentioned what kind of surgeries you have had, but every abdominal surgery
causes adhesions inside the abdominal cavity. Such adhesions can cause partial bowels obstruction and give abdominal pain
like yours. That is why it should be ruled out as well.
I suggest you to have upper GI endoscopy
performed to check for peptic ulcers and to rule out the cancer. Discuss with your doctor about bowels obstruction and possible gallbladder
disease. HIDA scan and abdominal CT with oral contrast should be considered if endoscopy will be negative.
Hope this will help.
