The underlying cause may involve infection, inflammation, vascular occlusion or bowel obstruction. [7] The pain may elicit nausea and vomiting, abdominal distention, fever and signs of shock. [7] A common condition associated with acute abdominal pain is appendicitis. [8] Here is a list of acute abdomen causes:
It is a cause of portal hypertension and can cause bowel ischemia sometimes leading to bowel infarction. Diverticulitis (26.5%) and acute appendicitis (22%) are the two most common causes. Pylephlebitis is caused by a single pathogen in 43% of cases and polymicrobial in 27% of cases.

However, it has been proposed to be used in those who are pregnant and have inconclusive findings on ultrasound. The sensitivity and specificity of MRI in diagnosing acute appendicitis are 94% and 96% respectively. [2] Laparoscopic surgery has also been used to diagnose the cause of IAIs when imaging is unhelpful.
