Diagnostic Process for Small Intestinal Disease

  • Takayuki Matsumoto


The small intestine is the longest organ of the digestive tract, with main functions of digestion, absorption, and maintenance of innate immunity. Accordingly, symptoms of small intestinal disease comprise impaired digestion and absorption due to widespread damage to the intestinal mucosa, as well as diarrhea, abdominal pain, and malnutrition caused by immune abnormalities. The development and widespread adoption of small intestinal endoscopic techniques has increased the frequency with which small intestinal lesions are diagnosed following hemorrhage from a small lesion. Symptoms of small intestinal disease must therefore be categorized into two types: gastrointestinal hemorrhage; and other symptoms. The latter are suggestive of more widespread small intestinal disease.
