The jejunal loops are absent on the left.

Case Discussion

Paraduodenal hernias are a rare type of hernia that results from malrotation of the small intestine during embryonic life. Paraduodenal hernias can arise on the right or on the left.

Clinical manifestations can be variable and non-specific, from asymptomatic, to occlusion and intestinal ischemia. The average age of onset is about 40 years.

In this case, the diagnosis was confirmed surgically.

Operative report

Open laparoscopy

There are parietal adhesions from previous interventions. The omentum moves upward and jejunal loops are visible at the level of the paraduodenal region.

Laparotomy
