A fish out of the Meckel diverticulum, foreign body bowel perforation: a case report.

Meckel's diverticulum is the most common congenital abnormality of the gastrointestinal tract, caused by incomplete obliteration of the omphalomesenteric duct during the seventh week of gestation, and occurs in up to 4% of the general population. Most patients are asymptomatic; however, in a few cases, patients present with gastrointestinal bleeding and intestinal obstruction. Perforation of the diverticulum due to a foreign body is a very rare complication since most ingested foreign bodies may pass through the gastrointestinal tract without consequences. We present the unusual case of a 73-year-old female who inadvertently ingested a fishbone that lodged and perforated a Meckel diverticulum. After surgery, the patient fully recovered.
