Go With the Flow: Lumen-Apposing Metal Stent for Drainage of Duodenal Abscess

Duodenal diverticula are common but rarely complicated by abscess formation. Standard management includes antibiotics, percutaneous drainage, or surgery when minimally invasive approaches fail. We report a 75-year-old woman with a 4.4 × 4.0 cm duodenal diverticular abscess refractory to antibiotics. Endoscopic ultrasound-guided drainage with an 8 × 8 mm lumen-apposing metal stent led to immediate pus evacuation and clinical resolution. This case illustrates the expanding role of lumen-apposing metal stents as a safe, minimally invasive option for complex duodenal abscesses when conventional approaches are not feasible.
