Abstract

1. Introduction
Internal hernia (IH) is a protrusion of intra-abdominal viscus, usually the small bowel, through an aperture in the peritoneum or the mesentery within the abdomen or the pelvis [1]. Internal hernia can be congenital like paraduodenal and pericecal or acquired like post-surgery or due to a blunt abdominal trauma. Herniation through the omentum in a virgin abdomen is rare but has been reported in some case series due to congenital omental defect [2]. Although IH is rare, it causes 0.6– 5.8% of small bowel obstruction [1]. Due to growing of the surgical procedures like gastric bypass for bariatric management and liver transplantation, the incidence of internal hernia has increased recently [1].
