Superior mesenteric artery (SMA) syndrome is an uncommon cause of duodenal outlet obstruction. Symptoms and signs suggestive of this condition are nonspecific, and a high index of suspicion coupled with appropriate imaging studies are necessary for diagnosis. We present the case of a 70-year-old man who developed SMA syndrome following prolonged hospitalisation for a surgically treated bleeding duodenal ulcer. His SMA syndrome resolved after successful nonoperative management based on accepted guidelines for nutritional therapy, thus avoiding the need for reoperation and its attendant risks in a malnourished patient.
肠系膜上动脉（SMA）综合征是十二指肠出口梗阻的不常见原因。提示这种情况的症状和体征不具有特异性，需要高度怀疑并结合适当的影像学研究来进行诊断。我们报告了一例 70 岁男性的病例，他在因手术治疗的十二指肠溃疡出血而长时间住院后发生了 SMA 综合征。他的 SMA 综合征在基于营养治疗的公认指南成功的非手术治疗后得到解决，从而避免了在营养不良患者中再次手术及其相关风险。
