From Recurrent Pain to a Life-Threatening Condition: A Case Report of Left Paraduodenal Hernia

Paraduodenal hernia (PDH) is the most frequent type of congenital hernia, especially on the left side. Although acute intestinal obstruction due to internal hernias is rare, it can be life-threatening if not detected and treated promptly. Here, we present the case of a 36-year-old man who presented to the emergency department with an acute intestinal obstruction that had been developing for three days. The patient had a history of recurrent abdominal pain but had never undergone any abdominal surgery. Surgical exploration revealed a left internal PDH with a collection of incarcerated jejunal loops retrocolically encased within the hernial sac. Resection of the gangrenous jejunal loops was performed, followed by hernia reduction and neck closure. This case highlights the importance of timely and accurate diagnosis of left PDHs, particularly in patients with a history of recurrent abdominal pain and no prior abdominal surgeries. Early detection and treatment can prevent life-threatening complications such as intestinal perforation and peritonitis.
