Idiopathic Small Bowel Diaphragm Disease Without Use of Non-steroidal Anti-inflammatory Drugs: A Case Report and Review of the Literature.

Small bowel diaphragm disease is a rare condition that is characterized by the presence of diaphragm-like strictures that causes intermittent or complete small bowel obstruction. Most cases are asymptomatic until presented with severe abdominal pain due to small bowel obstruction or diagnosed during anemia workup as a cause of occult gastrointestinal bleeding. Small bowel diaphragm disease is usually associated with long-term use of non-steroidal anti-inflammatory drugs (NSAIDs). Here, we present the case of a 50-year-old male with no history of NSAID use who presented with abdominal pain and iron deficiency anemia. He was postoperatively diagnosed with idiopathic small bowel diaphragm disease.
