The connective tissue disorders are a protean group of acquired diseases which have in common widespread immunologic and inflammatory alterations of connective tissue. The acquired connective tissue diseases generally include the following clinical entities: rheumatoid arthritis, systemic lupus erythematosus, polymyositis, polyarteritis nodosa, scleroderma, mixed connective tissue disease, Sjögren's and Behcet's sindromes. These entities have certain features in common which include sinovitis, pleuritis, myocarditis, endocarditis, pericarditis, peritonitis, vasculitis, myositis, changes in skin, alteration of connective tissue and nephritis. Gastrointestinal and hepatic involvement in connective tissue disorders are not the most important features, nevertheless appear almost regularly. Anorexia, nausea, vomiting, abdominal pain, malabsorption may affect patients suffering by rheumatoid arthritis, systemic lupus erythematosus and other collagenophaties. In some cases mesenteric vasculitis may cause intestinal ischemia which may result in bowel infarction, mucosal ulceration, hemorrhage, perforation. After an extensive review of the existing literature the Authors make an accurate evaluation of gastrointestinal and hepatic alterations in connective tissue diseases.
