Postoperative intussusception is an unusual clinical entity in adults, and is rarely encountered as a complication following gastric surgery. The most common type after gastric surgery is retrograde jejunogastric intussusception, and jejunojejunal intussusception has been rarely reported. We report a case of anterograde jejunojejunal intussusception after radical subtotal gastrectomy with Billroth II anastomosis in a 38-year-old Korean woman with early gastric cancer, and include a review of the literature on this unusual complication.
