Left Paraduodenal Hernia

Abstract

250 An internal hernia is a protrusion of abdominal viscera through a normal opening or defect in the peritoneum or mesentery. Internal hernias can be congenital or acquired1. True internal hernias can be further classified by their locations; para duodenal 53%, pericecal 13%, foramen of Winslow 8%, transmesenteric and trans mesocolic 8%, inter sigmoid 6%, retro anastomotic 5%2. Internal hernias are a rare cause of intestinal obstruction accounting for less than 2% and approximately 4% of obstruction caused by hernias1. Although para duodenal hernias are the most common type of congenital internal hernias and constitute around half of the cases; the incidence of para duodenal hernias are considered very rare1-5. However, with the increasing trend of bariatric surgeries, the incidence of acquired internal hernias are increasing1.
