Abstract:
Acute colonic pseudo-obstruction (ACPO) is obstruction of the large bowel without a mechanical cause. The exact mechanism remains incompletely understood but is thought to result from disruption to the autonomic regulation of the colon, typically in the context of hospitalized patients with medical illness, precipitating medications, or recent surgical intervention. This paper presents an unusual case of ACPO in an ambulatory patient with a recently passed renal calculus, explores the anatomy and physiology underlying the autonomic dysfunction theory of ACPO pathogenesis in the context of the case, and provides a 3D reconstruction of the patient\'s CT to illustrate the abrupt caliber change at the splenic flexure characteristic of ACPO.
摘要:
急性结肠假性梗阻(ACPO)是指无机械原因的大肠梗阻。确切的机制仍未完全了解,但被认为是由于结肠自主神经调节的破坏所致。通常在住院的医疗疾病患者的情况下,沉淀药物,或最近的手术干预。本文介绍了一名最近通过肾结石的门诊患者的ACPO异常病例,在病例背景下探索ACPO发病机制的自主神经功能障碍理论的解剖学和生理学,并提供了患者CT的3D重建,以说明ACPO的脾弯曲特征处的突然口径变化。
