Answers
1.b
All the choices are for acute abdomen but an executive with pain radiating to the back most likely has acute pancreatitis. Duodenal ulcer perforation is mostly anterior and chances of pain in the back are less. Also with the advent of effective drugs the incidence of gastric and duodenal ulcers has decreased. Acute gastritis will also not present with pain going to the back. Acute appendicitis has shifting pain to Right iliac fossa and aortic aneurysm is the disease in the 6th or 7th decade
The diagnosis of Acute pancreatitis is confirmed by amylase, lipase and CT findings.
