Retrograde jejunojejunal intussusception is an unusual complication of gastric surgery. Mortality rates are quite high, especially if corrective surgery is delayed for more than 48 hours. The common symptoms of retrograde jejunojejunal intussusception are epigastric pain, nausea, vomiting or hematemesis, and palpable mass. UGI series, abdominal sonography, abdominal CT, and endoscopy can be used to diagnose of retrograde jejunojejunal intussusception. We experienced two cases of retrograde jejunojejunal intussusception. One was a sixty-one-year-old male who was admitted because of epigastric pain, nausea and hematemesis. He had previously undergone total gastrectomy with Braun anastomosis due to gastric cancer seven years before. Abdominal CT and endoscopy were performed for diagnosis of intussusception of the upper jejunum. The other case was fifty-nine-year-old male who was admitted because of abdominal pain and vomiting. He also had previously undergone total gastrectomy with Braun anastomosis due to gastric cancer seven years before. On physical examination, the abdomen was flat and the mass was palpated in periumbilical area. UGI series, abdominal CT, and abdominal sonography were performed. Both cases underwent operation by segmental resection of the intussusceptum and the patients discharged without complication. We experienced two cases of unusual retrograde jejunojejunal intussusception and report with a review of the literature.
