Intestinal obstruction due to anomalous congenital band

Abstract

Intestinal obstruction caused by an anomalous congenital band is very rare in adults and  children. ACBs (Anomalous congenital band) are bands that have no identifiable embryological or acquired basis. We report an unusual case of intestinal obstruction in a 23 year old male patient who was found to have an ACB forming a loop around the jejunum (Fig-1) and causing closed loop obstruction. This band was arising from the treitz ligamentum and looping around the jejunum, ending at the root of mesentery. This band was in addition, causing compression of blood supply to the proximal jejunum.
