Upper gastrointestinal series is the modality of choice for the evaluation of malrotation, as it will often show an abnormal position of the duodenum and duodeno-jejunal flexure (ligament of Treitz). In cases of malrotation complicated with volvulus, upper GI demonstrates a corkscrew appearance of the distal duodenum and jejunum.

An upper GI bleed is more common than lower GI bleed. [2] An upper GI bleed occurs in 50 to 150 per 100,000 adults per year. [8] A lower GI bleed is estimated to occur in 20 to 30 per 100,000 per year. [2] It results in about 300,000 hospital admissions a year in the United States. [1] Risk of death from a GI bleed is between 5% and 30%.
