Anterograde jejunojejunal intussusception resulted in acute efferent loop syndrome after subtotal gastrectomy

Figure 1 Radiologic, endoscopic and intraoperative findings of anterograde jejunojejunal intussusception. A: Abdominal computed tomography showed a non-homogeneous mass (arrow) in the left upper quadrant of the abdomen; B: A J-turn view of gastrofibroscopic examination demonstrated a congested jejunal mass (intussusceptum); C: Intraoperative findings revealed that the intussusception started just below the gastrojejunostomy anastomosis. The black arrow indicates the intussuscipiens, and the white arrow indicates the intussusceptum; D: Schematic diagram of the intussusception at the efferent-loop.
