This fold is called the small bowel mesentery. Inflammation and scarring (fibrosis) of the small bowel mesentery are the main features of sclerosing mesenteritis.inding the cause has been difficult, but it is thought that patients with sclerosing mesenteritis have had abdominal surgery or trauma to the abdomen.
