Gastrosplenic Fistula without Malignancy Management in a 16-Year-Old Boy

Gastrosplenic fistula is a very rare entity, most commonly occurring as a distinctive complication of splenic or gastric malignancies, most notably diffuse large B cell lymphoma (DLBCL). Benign gastric ulcer, splenic abscess, and Crohn's disease have also been reported as possible causes. We report a nonmalignant case of 16-year–old male with a gastrosplenic fistula of unclear etiology. The fistulous tract was confirmed by an upper endoscopy and an upper gastrointestinal series. Subsequently, it was surgically managed with a subtotal gastrectomy with “Roux-en-Y” reconstruction and a feeding jejunostomy.
