Overview
- Protrusion of the viscera through the peritoneum or mesentery and into a compartment in the abdominal cavity. [1] [2]
- Most common presentation is an acute intestinal obstruction of small bowel loops that develops through normal or abnormal apertures.
- Responsible hernial orifices are usually preexisting anatomic structures, such as foramina, recesses, and fossae.
- Pathologic defects of the mesentery and visceral peritoneum, which are caused by congenital mechanisms, surgery, trauma, inflammation, and circulation, are also potential herniation orifices.
Types of internal hernias
- Foramen of Winslow
- Paraduodenal
- Transmesenteric
- Transomental
- Pericecal
- Sigmoid mesocolon
- Supravesical
- Pelvic hernias
Diagnostic Findings
Computed Tomography
- Encapsulation of distended bowel loops with an abnormal location, arrangement or crowding of small-bowel loops within the hernial sac, evidence of obstruction with segmental dilatation and stasis.
- Mesenteric vessel abnormalities, with engorgement, crowding, twisting, and stretching of these vessels
Patient #1: Patient presents with intermittent abdominal pain. The patient had a history of gastric bypass
