Jejunitis

Jejunitis is inflammation of the lining of the middle section of the small intestine.^[1] It is characterized by severe abdominal pain, vomiting containing bile, and foul smelling loose stools.^[2] Acute jejunitis comes on suddenly and usually only lasts a few days. Less commonly, a chronic condition may cause persistent jejunitis.^[3]

Jejunoileitis

Jejunoileitis is Crohn's disease of the Jejunum.^[4] Jejunoileitis is an uncommon type of Crohn's disease with high morbidity and challenges in medical management. Common symptoms include:

• Colicky abdominal pain (91%)
• Weight loss (62%)
• Diarrhea (53%)

Most patients had severe symptoms and required at least one operation for jejunoileitis, with two-thirds of patients requiring two or more operations. The combination of anti-inflammatory drugs with the relief of recurrent obstructive symptoms by strictureplasty and resection can together produce a good long term prognosis in most patients with jejunoileitis.
