Transabdominal ultrasound is usually the first investigation to check for gallbladder disease. When the results are not clear, the next test is often a HIDA scan and, if necessary, a MRCP or ERCP, depending on the suspected problem.
Endoscopic ultrasound is more sensitive than transabdominal ultrasound in showing stones, sludge, polyps and cancer in both the gallbladder and bile ducts.
I’m doing some research about gallbladder tests and I want to get some general idea, preferably from a primary doctor’s viewpoint, about how commonly is endoscopic ultrasound actually used (as a second investigation after transabdominal ultrasound) to check for gallbladder disease, for example, in the US or UK. I don’t need any statistical data, just some estimation – is it widely used today or not really.
