Q

Long history……. How to visualize the normal position of duodenojejunal junction?

A) Right lateral then supine
B) Full stomach to make sure there is gastric emptying
C) Use barium

A

A) Right lateral then supine

Barium is not used in potential volvulus cases because if rupture were to happen it leads to
chemical peritonitis.
