| Comment: -The topic of appendicitis
is controversial only in defining an ideal protocol. Popular protocols
(all with excellent results in the literature) include using no oral or
IV contrast, using both IV and oral contrast, using rectal contrast, or
oral contrast only. I like using IV contrast for a number of reasons including
the fact that in many cases other diagnoses are the cause of the patients
symptoms and are best detected with IV contrast. |
