Vitamin A deficiency associated with retinopathy and night blindness was observed in a patient 4 yr after jejunoileal bypass. Upon further investigation, a multiple vitamin deficiency state was established. Daily supplementation with 30 000 units of vitamin A resulted in normal levels of vitamin A and retinol-binding protein. The patient's night blindness improved, but his retinopathy remained unchanged as demonstrated by fluorescein angiography. We conclude that patients who have undergone jejunoileal bypass should be supplemented with vitamin A since the vitamin A deficiency is preventable and the retinopathy associated with the deficiency may not be totally reversible.
一名患者在空肠回肠旁路手术后4年出现与视网膜病变和夜盲症相关的维生素A缺乏症。进一步检查后，确定为多种维生素缺乏状态。每日补充30000单位维生素A后，维生素A和视黄醇结合蛋白水平恢复正常。患者的夜盲症有所改善，但荧光素血管造影显示其视网膜病变仍无变化。我们得出结论，接受空肠回肠旁路手术的患者应补充维生素A，因为维生素A缺乏是可预防的，且与该缺乏相关的视网膜病变可能并非完全可逆。
