Sclerosing mesenteritis: It is part of a spectrum (including mesenteric lipodystrophy and mesenteric panniculitis) of idiopathic primary inflammatory and fibrotic processes that affect the mesentery. Pathophysiologically, these processes may affect the integrity of the gastrointestinal lumen and mesenteric vessels by a mass effect. Sclerosing mesenteritis occurs when the tissue mesentery that holds the small intestines in place becomes inflamed and forms scar tissue.Sclerosing mesenteritis can cause abdominal pain, bloating and diarrhea. In rare cases, scar tissue formed by sclerosing mesenteritis can block food from moving through your digestive tract. Surgery may be necessary in this situation.
sclerosing mesenteritis is asymptomatic, gastrointestinal symptoms such as abdominal pain, nausea/vomiting, bloating, loss of appetite, weight loss and diarrhea or constipation, Occasionally, intermittent partial bowel obstruction is encountered. Non-gastrointestinal symptoms include fatigue, weight loss, night sweats and fever.
Idiopathic sclerosing mesenteritis (ISM) is an uncommon disease involving the small bowel mesentery and characterised by chronic inflammatory changes ultimately progressing to fibrosis. The first reported series featured 34 cases of "retractile mesenteritis and mesenteric sclerosis"; published in 1924
