title: Meckel's diverticulum perforation by a fish bone: A case report.
abstract: BACKGROUND
  Meckel's diverticulum is the most common congenital abnormality of the gastrointestinal tract. The perforation of a Meckel's diverticulum by a foreign body is a very rare complication.
  
  
  METHODS
  A 61-year-old male presented to the Emergency Department with complaints with abdominal pain and fever, and abdominal rebound tenderness on physical examination. An intestinal perforation by a foreign body was diagnosed by CT scan. The patient was submitted to a diagnostic laparoscopy and a perforation of a Meckel's diverticulum by a foreign body was identified. The foreign body was removed and a stapled diverticulectomy was performed.
  
  
  CONCLUSIONS
  Meckel's diverticulum is asymptomatic in most of the affected individuals, with a 4.2-16.9% probability of symptomatic presentations. The clinical presentation ranges from intestinal obstruction, to bleeding, inflammation and perforation. While children with Meckel's diverticulum present more often with gastrointestinal bleeding, intestinal obstruction is the most common presentation in adults. Foreign body perforation of a Meckel's diverticulum is an extremely rare event. There is general agreement that a symptomatic Meckel's diverticulum should be resected. Laparoscopy is a safe diagnostic and therapeutic tool that can decrease diagnostic time and theoretically avoids the morbidity and mortality of a delayed diagnosis.
  
  
  CONCLUSIONS
  The perforation of a Meckel diverticulum by a foreign body is an extremely rare event and may have a bad prognosis in case of a delayed diagnosis.
