The reasons for this herniation remain unclear, although several predisposing factors have been postulated by Moynihan: (a) a long or excessively mobile mesentery, (b) excessively large Foramen of Winslow, (c) absence of fusion of ascending colon to posterior abdominal wall .
For vascular injury to occur (with any means of trocar insertion), the trocar not only would have to enter the peritoneal cavity but would need to pass through it entirely and impale vessels against the posterior abdominal wall.
The peritoneum tends to release a fan-shaped formation, which holds the jejunum and ileum to the posterior abdominal wall, and is composed of two layers, having a sufficient extension to allow considerable mobility to this portion of small intestine; this formation is the mesentery, which will receive the prefixes of the organ where it is attending as the case of the mesojejunum, demonstrated in Figure 5.
The posterolateral branches supply the body wall, which includes the inferior aspect of the diaphragm, posterior abdominal wall and the related structures and fascia and these include the inferior phrenic arteries and the lumbar arteries.
This trial aimed to assess the value of MRI in the differential diagnosis of chronic groin pain in athletes, a condition caused by various pathologies, the most common being posterior abdominal wall deficiency, osteitis pubis and muscular imbalance.
