Five patients with bile stained vomiting due to external obstruction of duodenum and duodenojejunal junction are presented. Intestinal rotation seen in these patients was defferent from typical malrotation described by with Grob's, Snyder', or Louw'. We suggest that following 7 factors should be described for correct understanding of anatomy; degree of rotation of duodenal loop, degree of rotation and fixation of ceco-colic loop, presence or absence of volvulus, duodenal band, Ladd's band, adhesion of intestine, and kinking or angulation of intestine. Upper GI X-ray with barium meal is essential for the diagnosis, and individually modified surgical procudure should be considered according to the type of the disease.
