Abstract

An isolated tubular intestinal loop (ITIL) means an anatomical or vascular communication with rest of the bowel loop and may provide an insight into the pathogenesis of intestinal atresia. We experienced a case of an ITIL identified in omentum of a 4-day-old neonate with type-II intestinal atresia. To our knowledge, this association has never been reported in the English literature. Omental wrapping of the incompletely resorbed ischemic bowel segment may explain this phenomenon in a case of congenital intestinal atresia.

Figure

• 

  Fig. 1 Operative findings of intestinal atresia showing type I atresia and a tubular structure (indicated by arrow) embedded in omentum, and a cord-like band (indicated by arrowhead).

• 

  Fig. 2 A longitudinal section of the atretic portion showed atresia with interruption of bowel continuity. A microscopic findings of the atretic part shows loss of continuity with separation by fibrous septum (inside box).

• 

  Fig. 3 Cross section of the tubular structure shows degenerated intestine with 4 layers with luminal obstruction (H&E stain).
