Ingestion of gastrointestinal (GI) foreign bodies represents a challenging clinical scenario. The greater risk is at extremes of age, in those wearing dentures, alcoholics and mentally handicapped. We present a case of duodenal perforation caused by a bird feather. A 64-year-old man was presented with abdominal pain for 4 days. Abdominal examination showed signs of peritonitis. The erect abdominal x-ray showed free gas under diaphragm. Exploratory laparotomy showed purulent fluid, but no definite site of perforation could be found. So the abdomen was closed with a drain in Morison's pouch. The postoperative recovery was uneventful. He came for a repeat check-up at 4 weeks with dull aching pain in the upper abdomen and was advised for a routine upper GI endoscopy which revealed a feather penetrating the first part of the duodenum, which was removed with a foreign body removing forceps. GI foreign bodies represent a significant problem and an increased level of suspicion is important for timely diagnosis and treatment.
