对胃切除术后的骨病研究多提示此病为一种骨软化症,但对其病因尚有争议。多数认为与饮食中钙和维生素D摄入不足、脂肪泻所致各种消化不良或吸收不良等有关。25-羟维生素D浓度降低的发现支持维生素D缺乏为致病因素之一,但尚缺乏对胃切除术后钙和维生素D代谢调节的研究。作者调查3～14年前在Glostrup医院施行过部份胃切除的患者171例。经剔除59例作过两次或两次以上手术者、61例新生物、酒精中毒性肝病、糖尿病或其它疾病者及失访者之后,对剩下的34例分成Billroth Much research on bone disease after gastrectomy suggests that the disease is a form of osteomalacia, but the cause is controversial.
