Acute abdominal pain is the most common complaint to visit the emergency room comprising approximately 5% of total visits (1-13). A small percentage of patients with acute abdominal pain were not diagnosed during the first evaluation because of the early stage of the disease or subtle and atypical signs (13). On the other hand, acute abdominal pain is associated with many challenges for a clinician due to owing to the variety of underlying causes, although it is not typically serious (14). Moreover, accurate and early diagnosis of acute abdominal pain prevents mortality and morbidity due to life-threatening conditions (15) that require urgent management such as appendicitis, intussusception, or bowel obstruction (13).
