a 54 years old man has acute pain several hours after the rubber band ligation of a prolapsing hemorroid. which of the following is the most explanation for a pain?
A the ligation involved the mucous lining of the anal canal
B the ligation stopped the blood supply of the hemorriod
C the ligation was done at the level of the anal column
D the ligation done inferior to the pectinate line
E the ligation done was on internal hemorrid
can anyone answer for me?
I think the answer is E. This is most likely external hemorrhoid, which is situated below the pectinate line; they are coverred with skin, and are more painful than internal hemorroids b/c their pain fibers are carried by GSA fibers of the inferior rectal nerves.
but i don't think (e) is correct
any idea as i think (d) is more correct
and i can't decide
any idea???

yes, I am sorry. The answer is D, by mistake I wrote E. You are correct.
pectinate line; they are coverred with skin, and are more painful than internal hemorroids
