Something of a followup to a previous question I asked:
Is an upper endoscopy (esophagogastroduodenoscopy or EGD) able to spot gallbladder problems? I have not really found a consistent answer in a few sources I looked at:
- MUSC Health: Upper Endoscopy (EGD) makes no mention of gallbladder
- What is EUS? says an EUS, endoscopic ultrasound, is needed
- ASGE suggests that a specialized endoscopy (Endoscopic retrograde cholangiopancreatography (ERCP)) might work (but that seems more complex than an EGD)
However, an upper endoscopy does take a peek at the duodenum. Would there be signs of gallbladder problems there, or not?
