Pdf Summary

The document discusses various diseases and disorders related to the small intestine in the gastrointestinal tract. Celiac sprue is an autoimmune disease where exposure to gluten causes damage to the small intestine. It is diagnosed through serologic testing and endoscopic biopsies, and treatment involves strict avoidance of gluten. Obscure gastrointestinal bleeding is bleeding from the GI tract without an obvious cause, and it can be evaluated through repeat endoscopy, capsule endoscopy, and device assisted enteroscopy techniques. Small bowel obstruction is a mechanical or functional blockage of the small intestine that causes symptoms like abdominal pain, distension, and constipation. Diagnosis involves X-rays or CT scans, and treatment may involve decompression and surgery. Mesenteric ischemia is inflammation and injury of the small intestine due to inadequate blood supply. Acute mesenteric ischemia is caused by blockage of the mesenteric artery, while chronic mesenteric ischemia is associated with atherosclerosis. Diagnosis involves angiography and treatment typically requires surgery. Overall, understanding the causes, symptoms, diagnosis, and treatment of these small intestine disorders is crucial for managing gastrointestinal health.
