Several factors are involved, including rapid weight loss, rapid statural growth without weight augmentation. Diagnosis is suspected when an improvement is achieved by ventral decubitus and it is confirmed by plain films of the abdomen, GI study with barium and echography, measuring the aortomesenteric angle (inferior to 25-30°). Patients must at first be treated conservatively. Surgery is indicated for occlusive episodes with unsuccessful conservative therapy. The authors report 3 cases with different clinical presentation. However, all the patients presented important weight loss and vomiting.展开更多
