Incarcerated Left Paraduodenal Hernia as a Rare Cause of Acute Abdomen: A Case Report and Literature Review.

Internal hernias are one of the rare causes of intestinal obstruction and usually is the diagnosis of exclusion. Para-duodenal hernias (PDH) are rare congenital disorders that occur due to malrotation of the midgut in the embryonic phase of development. They can be asymptomatic or can present as an incarcerated, strangulated, or even obstructed internal hernia. It is difficult to diagnose clinically and often requires supportive radiological investigations. Herewith, we present a case of a 30-year-old male who presented with a short history of persistent pain in the abdomen. Contrast-enhanced computed tomography (CECT) showed the presence of an uncomplicated left para-duodenal hernia. Emergency diagnostic laparoscopy was done in view of abdominal tenderness, and a diagnosis of incarcerated PDH was made. The PDH was then tackled laparoscopically. We present this case to highlight the importance of suspecting a PDH with complications in an acute abdomen and the need to intervene surgically based on clinical judgment.
