Endoscopic Ultrasound-Guided Drainage of Intramural Duodenal Abscess Caused by Foreign Body Ingestion

A 63-year-old man presented with fever and generalized weakness for 2 days. Computed tomography scan showed an intramural duodenal abscess and a linear radiolucent foreign body penetrating the duodenal wall. Endoscopic drainage was performed. Endoscopic ultrasound showed fluid collection in the second portion of the duodenum. The duodenal lumen was punctured with the creation of stoma using a lumen-apposing metal stent and electrocautery system. The stent was deployed, and the drainage of purulent fluid followed. The foreign body was suspected to be a wire brush bristle. The patient received intravenous antibiotics for 14 days. Follow-up images showed the resolution of the abscess.
