Gastrointestinal Manifestations, Diagnosis, and Management of Hereditary AngioedemaJalaj, Sujai MD; Scolapio, James S. MDJournal of Clinical Gastroenterology: November/December 2013 - Volume 47 - Issue 10 - p 817–823 doi: 10.1097/MCG.0b013e31829e7edf Clinical Review Abstract Author Information Abdominal pain is one of the most common conditions in clinical practice and yet a challenging complaint to accurately diagnose due to the vast number of possible etiologies. When other health care providers cannot identify the cause of abdominal pain, gastroenterologists are often looked upon to help solve the diagnostic dilemma. Consequently, it is incumbent upon gastroenterologists to be well versed in the diagnosis and management of not only common but also rare causes of abdominal pain. One such uncommon but well-described cause of abdominal pain is angioedema of the intestinal tract due to hereditary angioedema. Acute onset, recurrent abdominal pain of varying severity is its most common presenting symptom, and misdiagnosis can not only lead to unnecessary surgical procedures but also death. The purpose of this review is to raise awareness among gastroenterologists about hereditary angioedema as a potential cause of recurrent, unexplained abdominal pain.
