PARADUODENAL HERNIA- AN OBSCURE AND PERILOUS CAUSE OF INTESTINAL OBSTRUCTION.

Abstract

Paraduodenal hernias (PDH) constitute more than half of internal hernias. Both left and right PDH occur due to error of rotation of gut and defective fusion of mesocolon and mesentery with posterior parietal peritoneum.  Clinical diagnosis of PDH is very difficult because of its varied presentation and nonspecific symptoms. Prompt diagnosis and surgery is imperative to avoid strangulation of bowel which is associated with high mortality. Before the advent of CECT many were discovered during exploratory laparotomy or unrelated abdominal surgery. Now CECT abdomen has become the gold standard for pre-operative diagnosis of PDH. We report two cases of PDH, one on left side and another on right side, diagnosed preoperatively and treated successfully.
