Final answer:
Gastritis is inflammation of the stomach lining, gastric varices are enlarged veins in the stomach, and chronic pancreatitis is inflammation of the pancreas. Endoscopic ultrasound and endoscopic retrograde cholangiopancreatography (ERCP) are tests used to diagnose and evaluate these conditions.
Step-by-step explanation:
Gastritis is inflammation of the stomach lining, often caused by infection with Helicobacter pylori or the use of certain medications. Gastric varices are enlarged veins in the stomach that can occur as a result of liver disease. Chronic pancreatitis is a long-term inflammation of the pancreas, often caused by conditions such as gallstones or chronic alcohol use.
Endoscopic ultrasound and endoscopic retrograde cholangiopancreatography (ERCP) are two tests that can be used to diagnose and evaluate conditions such as gastritis, gastric varices, and chronic pancreatitis. Endoscopic ultrasound uses sound waves to create images of organs in the abdomen, while ERCP involves placing a tube down the throat to visualize the bile and pancreatic ducts using dye and X-ray imaging.
In this case, the EGD (endoscopy) revealed gastritis and gastric varices, which are associated with the patient's history of chronic pancreatitis.
