Background
Herniation of the gastrointestinal tract is a common clinical problem that can occur at a variety of locations along the gastrointestinal tract. Location of the herniation often leads to distinct symptomologies, clinical presentations, and imaging findings. If not diagnosed appropriately, hernias can lead to severe, life-threatening complications. Multi-detector CT (MDCT) is useful for pre-operative planning to assess severity and determine if surgical intervention is needed. MDCT is also essential in the post-operative state to identify complications.

Educational Goals / Teaching Points
The educational goals of this review will focus on hernia demographics, imaging findings of various abdominal complications of these hernias, imaging considerations for preoperative planning, and potential postoperative complications.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
The distinct types of abdominal hernias that will be reviewed include inguinal, femoral, ventral, obturator, spigelian, Amyand, and periumbilical hernias. Hiatal hernias will also be discussed, including sliding hiatal hernias and paraesophageal hernias. Complications associated with these hernias that will be incorporated into this review include bowel obstruction, incarceration, strangulation, and perforation in abdominal hernias and esophageal stricture and gastric volvulus in hiatal hernias. The imaging considerations for preoperative planning will include size of hernia defects, previous mesh placement, visceral fat volume, and hiatal hernia classification. The postoperative complications of hernias discussed will include seroma, mesh-related infections, bowel entrapment, bowel obstruction, adhesions, bowel perforation, bladder injury, and hernia recurrence.

Conclusion
This educational exhibit will provide an overview of MDCT findings in abdominal hernias, as well as imaging considerations in pre-operative planning and post-operative complications.
