Endoscopic ultrasound (EUS)
An endoscopic ultrasound is a procedure performed by a gastroenterologist, who uses a combination of endoscopy and ultrasound to look at the digestive tract and nearby organs and tissues.
Pancreatitis refers to inflammation (swelling) of the pancreas. It is often caused by gallstones or heavy alcohol abuse. Both acute and chronic pancreatitis symptoms are similar.
Gallstones are parts of the bile stored in the gallbladder, such as cholesterol and bilirubin, hardened into solid matter. Symptoms can be pain in the upper abdomen, vomiting and sweating.
