RESUMO
Superior mesenteric artery syndrome or Wilkie syndrome is due to the compression of the third duodenum between the superior mesenteric artery and the aorta. It causes acute or chronic upper bowel occlusion. Abdominal CT scan facilitates the diagnosis. Severe malnutrition is its main etiological factor. Medical treatment can be based on aspiration of gastric contents and parenteral nutrition. If this fails, surgery is necessary. We here report the case of a 46-year-old patient, with a history of smoking, presenting with profuse postprandial bile and food vomiting. He had had weight loss of 7% over a period of 6 months. Upper GI endoscopy revealed non-stenotic antro-pyloric tumour mass. Histological examination showed poorly differentiated tubular gastric adenocarcinoma. Staging was without any peculiarity and allowed for the detection of superior mesenteric artery syndrome at an angle of 8°C. The patient received parenteral nutrition for 10 days, followed by inferior pole gastrectomy and gastrojejunal anastomosis (omega loop). The postoperative course was uneventful. Adjuvant chemotherapy was indicated.
