Fig. 2From: Novel variant of reversed midgut rotation – retro-arterial proximal jejunum and transverse colon: a case report and review of the literatureAnatomic illustrations of the gastrointestinal tract. a After normal midgut rotation: the duodenum is mostly in a retroarterial, and the jejunum and transverse colon are in an intraperitoneal position. b Anatomical situation in our present case: the transverse colon and the proximal jejunum are positioned posterior to the superior mesenteric artery axis. The ileocecal valve is found close to the midline in the mid-abdomen, whereas the hindgut is normally positioned. SMA superior mesenteric arteryBack to article page
