title: Sigmoid perforation caused by an ingested chicken bone presenting as right iliac fossa pain mimicking appendicitis: a case report.
abstract: BACKGROUND
  Gastrointestinal perforation due to a foreign body is not unknown. The foreign body often mimics another cause of acute abdomen and requires emergency surgical intervention. The majority of patients do not recall ingesting the foreign body. Perforations have been reported to occur in a pathologically abnormal colon.
  
  
  METHODS
  We report an interesting case of a 47-year-old Caucasian man who had a perforation of the sigmoid colon caused by an ingested chicken bone mimicking acute appendicitis. Our patient presented with right iliac fossa pain and local tenderness. When a laparotomy was performed, a chicken bone was found protruding through the sigmoid colon, which was found to lie in the right iliac fossa, thus mimicking acute appendicitis. Our case is different from previously reported cases in that perforation occurred in a non-pathological colon.
  
  
  CONCLUSIONS
  Our case emphasises the fact that the operating surgeon has to be aware of various differential diagnostic possibilities which mimic acute appendicitis. This has implications on the training of junior surgeons who are often involved in performing these procedures, and may do so out of hours. Care needs to be taken while obtaining consent for the necessary operation.
