A 45-year-old male comes into the emergency department with abdominal pain that has progressively worsened since the previous night. He also notes nausea and vomiting, but is afebrile. Upper gastrointestinal radiographic studies reveal that a loop of small intestine has passed through the epiploic foramen into the omental bursa and is constricted by the margins of the foramen as the intestine fills. The constriction should not be surgically relieved by opening the epiploic foramen because this procedure would risk cutting which of the following?

1. A)Pancreatic duct
2. B)Hepatic arteryGABARITO
3. C)Abdominal aorta
4. D)Hypogastric plexus
5. E)Hepatic vein
