  • Summary

    Key Learning Points

    1. 1. On an abdominal X-ray, the bowel is only visible when there is intraluminal gas or an air–fluid level, as the different densities are required to create contrast resolution so they can be perceived on a radiograph.

    2. 2. The 3/6/9 rule refers to the maximum size of specific sections of the bowel.

    3. 3. On an abdominal X-ray, the small bowel is normally central and valvulae conniventes can be seen. The colon, by contrast, is normally peripheral and has haustral folds which do not completely traverse the lumen.

    4. 4. In the early stages of pancreatitis, no abnormalities may be seen on CT imaging.

    5. 5. In cholecystitis, ultrasound is more sensitive than CT; however, CT is better at depicting complications such as perforation.

  • Gastric volvulus is a rare but potentially life-threatening cause of upper gastrointestinal obstruction. Emergency physicians must maintain a high index of suspicion in patients who present with signs and symptoms suggesting foregut occlusion. We report an illustrative case and review the pathogenesis, classification, diagnosis and treatment of this rare entity.
