Chicken bone in anal canal

Case contributed by Chris O'Donnell


Intense anal pain and low grade fever. Thought by the surgical registrar to have a perianal abscess.

Patient Data

Age: 65
Gender: Male

Inverted V-shaped foreign body consistent with a chicken bone in the anal canal without substantial surrounding inflammation

Case Discussion

Chicken bones can lodge in any part of the GI tract including the pharynx, doudenum, small or large bowel.  It is surprising that such a foreign body with sharp ends could pass through the entire bowel and end up lodging in the anus.  This is one rectal/anal foreign body that has not entered via a retrograde approach!
