The occurrence of intestinal obstructions secondary to rotational anomalies is relatively frequent in infancy. Owing to the complex evolution of the midbowel, such anomalies are largely limited to it, and volvulus of this portion of the gastrointestinal tract is thus the commonest cause of obstructions secondary to rotational accidents.
Our knowledge of intestinal rotation had its origins in the pioneer work of Mall7 (1898) and Frazer and Robbins3 (1915). However, it was not until Dott2 (1923) reported his clinical studies that a practical surgical application was made known. It remained for Ladd5 to demonstrate that these obstructive phenomena lent themselves to easy surgical correction, provided that the problem was recognized and that the surgeon was familiar with the mechanism involved.
The embryology of intestinal rotation has been well reviewed by Gardner4 and Aldrich et al.,1 and reference is made to their excellent articles. However,
