Internal hernia

Source: Wikipedia, the free encyclopedia.
A hernia—the hole in the light-colored wall of tissue—can trap loops of the bowel or other tissue.

Internal hernias occur when there is protrusion of an internal organ into a

small bowel obstruction.[1] Internal hernias can also trap adipose tissue (fat) and nerves. Unlike more common forms of hernias, the trapped tissue protrudes inward, rather than outward.[2]

Mesenteric defects commonly occur in trauma, such as

Roux-en-Y gastric bypass procedure, being classically known as a Petersen's hernia.[3] The mesenteric defect in such cases, called Petersen's defect, is located between the transverse colon and the mesentery of the alimentary limb (the segment of the jejunum from the jejunojejunostomy until the connection with the proximal segment of the stomach) at the level of the jejunojejunostomy.[4]

Internal hernias are difficult to identify in women, and misdiagnosis with

medical signs
of the hernia disappear. The hernia can typically only be detected when symptoms are present, so diagnosis requires positioning the woman's body in a way that provokes symptoms.

Both internal hernias and umbilical hernias are more common in women than men.[2]
