O, my dear colonoscope
You fill me up with so much hope
That my rectal inflammation
Will bring ascending deterioration
With voluminous bursts of dark bloody wastings
Incandescently lighting up my large intestines

And my keen biopsy needle
With a painful prick right in my middle
To show the elegance of my disease
Limited to mucousa only, it is

And my beloved sulfasalazine
To 5-ASA and sulfa you break up within
At the perfect moment, when you're most needed
By intestinal flora which are never depleted

And my corticosteroids, which are quite hard to rhyme
They do not let me use you for a very long time
For their adverse affects are adverse indeed
Far worse than just seem with a gluttonous creed
But absence makes the heart grow fonder with wait
So I love you best while I acutely exacerbate

They say that I am callous and cruel
Causing blood and mucus appear in the stool
They tear me with vengeance away from your body
Those men with green gowns and gloves that are bloody

I can never return
I must say goodbye
As we are buried together
The colon and I
