The syndrome results from a decreased angle between the SMA and the abdominal aorta, which compresses the third portion of the duodenum and obstructs the duodenal lumen. This report describes a 31-year-old male who presented with acute-onset vomiting and epigastric pain and was diagnosed with SMA syndrome. Although SMA syndrome classically presents with chronic symptoms, this case demonstrates an acute presentation in an otherwise healthy young adult. This case highlights the necessity of including SMA syndrome in the differential diagnosis of acute abdominal symptoms, even in patients without a chronic history, as early recognition and conservative treatment may prevent surgical procedures.  \nCategories: General Surgery, Internal Medicine, Gastroenterology  \nKeywords: conservative vs. surgical management, persistent vomiting, small-bowel obstruction, superior mesenteric artery (sma), superior mesenteric artery syndrome, wilkie’s syndrome  \nIntroduction  \nSuperior mesenteric artery (SMA) syndrome, also known as Wilkie’s syndrome, is a rare gastrointestinal disorder resulting from a reduced angle between the SMA and the abdominal aorta. This anatomical change compresses the third portion of the duodenum, resulting in mechanical obstruction of the duodenal lumen [1] . SMA syndrome is quite rare, with an incidence of 0 .1-0.3%[2] . Patients typically present with chronic symptoms such as postprandial epigastric pain, nausea, vomiting, and weight loss [3-6]. These symptoms can have intermittent exacerbations depending on the cause and grade of duodenal compression. In rare instances, symptoms may present acutely and progress to upper abdominal ileus [4] . The prevalence of SMA syndrome varies by symptom onset: acute cases occur at a rate of 0 .0108-0.0520 per 1,000 admissions, and chronic cases at a rate of 0 .965 per 1,000 admissions [4] . Because symptoms are often vague and nonspecific, misdiagnosis is common, and early diagnosis remains difficult [1] . Limited clinician awareness frequently leads to delayed diagnosis, prolonged disease course, and delayed imaging [4] .  \nCase Presentation  \nThe patient was a 31-year-old, thin-built male with a history of attention-deficit/hyperactivity disorder, daily vaping, and previous alcohol use who presented to same-day emergency care with a four-day history of acute-onset gastrointestinal symptoms. His illness began with the sudden onset of epigastric pain and several episodes of loose stools on day one. The loose stools persisted only for that initial day, after which he reported no further bowel movements. Within several hours of the onset of abdominal pain and diarrhoea, he developed nausea and vomiting, which progressively worsened over the next three days. Initially occurring a few times per day, the vomiting increased to five to ten bilious, non-bloody episodes daily by the time of presentation. His epigastric pain persisted throughout the four days, described as a constant dull ache without radiati","cbCaidse9QH68scm","https://ap.wps.com/l/cbCaidse9QH68scm","pdf",962077,"English","# Abstract\n# Introduction\n# Case Presentation\n## Imaging and Diagnosis\n## Exclusion of Differential Causes\n# How to Cite This Article","[{\"question\":\"What causes superior mesenteric artery (SMA) syndrome?\",\"answer\":\"SMA syndrome results from a decreased angle between the SMA and the abdominal aorta, compressing the third portion of the duodenum and obstructing the duodenal lumen.\"},{\"question\":\"How did this patient present, and why is it clinically notable?\",\"answer\":\"The patient developed acute-onset vomiting and epigastric pain over four days.
