Answer and Explanation 2

2.  The correct answer is B.  This patient has a clinical picture consistent with Zollinger Ellison Syndrome.  Somatostatin Receptor Scintigraphy is the single best imaging test for identifying this.  CLO testing is a biopsy test done during endoscopy to screen for H. Pylori and this would not be helpful because the patient is H. Pylori negative.  Prostaglandin levels have no correlation with the development of ulcers.  Cyclic AMP has nothing to do with the development of ulcers.  The only "cure" for Zollinger Ellison syndrome is if a gastrin secreting tumor can be found and be surgically removed.
