The patient underwent emergency surgery, and the cause of the perforation was identified as a piece of chicken bone.

Most foreign bodies pass through the gastrointestinal tract without any consequence. A very small percentage perforate the bowel, leading to acute abdomen and requiring surgical intervention. In most cases, the cause is discovered perioperatively. Foreign bodies such as dentures, fish bones, chicken bones, toothpicks and cocktail sticks have been known to cause bowel perforation ¹.

An abdominal radiograph is rarely helpful in making a diagnosis preoperatively, however a CT scan of the abdomen is considered the most useful imaging to detect foreign bodies or complications arising from them. The most common site of perforation is the terminal ileum and colon, although an increased incidence of perforation has been reported in association with Meckel's diverticulum, the appendix, and diverticular disease¹.
