Patient Data

Age: 60 years
Gender: Female

In the right hypochondrium, there is abnormal distension of some jejunal loops with air-fluid levels.


The jejunal loops and Treitz are on the right side, near the liver, with "small bowel feces" sign and hypertrophy of the Kerckring valves; it is associated whirl sign of the mesenteric vessels with modest peritoneal effusion.

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.
