Herniation Through Lesser Sac: A Rare Type of Primary Internal Hernia Causing Small Intestinal Obstruction

Abstract

Primary internal hernia is a rare phenomenon, where there is protrusion of an abdominal organ mostly gut through epiploic foramen. Clinical presentation of internal hernia is non specific.Imaging has been of limited utility in cases of acute intestinal obstruction; moreover ,interpretation of imaging features is operator dependant. Thus internal hernias are usually detected at laparotomy and preoperative diagnosis in an emergency setting is either difficult or most of the time not suspected We describe the case of a 14-year-old male who presented with acute abdominal pain and abdominal distension with no history of trauma .A loop of jejunum was found to enter the lesser sac with multiple peforated jejunal loop 35cm distal to dj junction. .The segment of perforated bowel loop of length 10cm was resected and jejuno-jejunostomy was done.This is a rare type internal hernia into lesser sac.
