Brief summary

Superior Mesenteric Artery Syndrome (SMAS) is a rare cause of duodenal obstruction, that should be suspected in cases of chronic, refractory upper digestive symptoms. Between 2008 and 2016, 39 consecutive patients with chronic gastrointestinal symptoms and a diagnosis of SMAS were prospectively included in the study, in order to describe their demographic, clinical and outcome features. All patients underwent duodenojejunostomy.
