Superior mesenteric artery syndrome (SMAS) is a rare and acquired anatomical condition characterized by vomiting, abdominal distension, weight loss and postprandial distress due to compression of the transverse portion of the duodenum between the superior mesenteric artery (SMA) and aorta, which causes duodenal outflow problems. We report a case series of three patients with SMAS. Diagnosis of the syndrome was made by augmenting a high degree of suspicion with repeat gastroscopies, CT scans and hypotonic duodenal contrast series showing compression of the horizontal part of the duodenum located between the vessels specified above. Medical therapy for the condition is aimed at nutritional rehabilitation so that weight gain results in relief of the obstruction. In each of our patients, surgical treatment was necessary during which the ligament of Treitz was divided and a side-to-side duodenojejunostomy was performed. In all, the weight loss seen preoperatively has been corrected.
肠系膜上动脉综合征（SMAS）是一种罕见的后天解剖学疾病，其特征为呕吐、腹胀、体重减轻以及餐后不适，这是由于十二指肠横部受到肠系膜上动脉（SMA）与主动脉之间的压迫，导致十二指肠流出道问题。我们报告了一组3例肠系膜上动脉综合征患者的病例系列。通过多次胃镜检查、CT扫描以及低张十二指肠造影系列检查增强高度怀疑，显示上述血管之间的十二指肠水平部受压，从而做出该综合征的诊断。该疾病的药物治疗旨在营养康复，以使体重增加从而缓解梗阻。在我们的每一位患者中，均有必要进行手术治疗，术中切断Treitz韧带并进行十二指肠空肠侧侧吻合术。总体而言，术前出现的体重减轻已得到纠正。
