Cancer associated with H Pylori
Gastric adenocarcinoma
Gastric mucosa associated lymphoid tissue (MALT) lymphoma
Big differences between Gastric and Peptic Ulcers
Gastric: worse with food, due to damaged lining, lesser curvature of the antrum
Peptic: better with food, due to too much H+, proximal duodenum
Zollinger-Ellison Syndrome (gastrinoma) is associated with…
MENS - pituitary adenoma, parathyroid hyperplasia, pancreatic tumors
Gastrin levels in ZES
greater than 1000
Esophagogastroduodenoscopy (EGD)
evaluates persistent heartburn, dysphagia, odynophagia, structural abnormalities
treatment and diagnosis
To detect subtle esophageal narrowing of the esophagus, what imaging technique should you use?
barium esophagography (barium swallow)
Hydroxy iminodiacetic acid scan is used for..
gallbladder abnormalities
Endoscopic Retrograde Cholangiopancreatography
used to detect biliary disease
diagnosis and treatment (removes stones)
*can lead to pancreatitis
