Left Paraduodenal Hernia: Rare Cause of Acute Intestinal Obstruction

Internal hernias are a rare cause of intestinal obstruction, representing less than 1% of cases. Preduodenal hernias, the most common type of internal hernias, are of a congenital origin. They may be asymptomatic, cause chronic abdominal pain, or present with an acute bowel obstruction with strangulation and ischemia. We report a case of a left preduodenal hernia found in a patient with acute intestinal obstruction.
