Diaphragm Disease of the Terminal Ileum: The Great Imitator.

Abstract

Non-steroidal anti-inflammatory drugs (NSAIDs) are associated with an array of intestinal injuries: erosions, ulcers, enteropathy, strictures and diaphragm disease. The diagnosis of diaphragm disease is challenging. Diaphragm disease can cause thin, concentric and stenosing strictures, which can induce intermittent or complete bowel obstruction. NSAID-induced lesions are reversible following discontinuation of the offending agent. Treatment of diaphragm disease can be conservative, endoscopic or surgical through stricturoplasty and/or segmental resection. We report a case of a 59-year-old female presenting with intermittent right lower quadrant pain diagnosed with diaphragm disease upon combined ileo-colonoscopy and histopathological analysis. Her diaphragm disease was successfully treated conservatively through drug cessation, avoiding more invasive procedures like endoscopic and surgical interventions.

Learning points: The incidence of diaphragm disease has been soaring due to the widespread use of non-steroidal anti-inflammatory drugs (NSAIDs).Diaphragm disease is characterized by diaphragm-like mucosal projections and annular constrictions that induce luminal narrowing and result in bowel obstruction.Physicians should get acquainted with diaphragm disease and include it in their differential diagnosis when approaching a patient with obstruction-like symptoms or non-specific and vague abdominal pain in the setting of chronic NSAIDs usage.
