急性结肠假性梗阻或非梗阻性结肠膨胀（Ogilvie综合征）临床表现酷似结肠的机械性梗阻。1948年Ogilrie首先描述了2例结肠极度膨胀的患者，部腹探查未发现梗阻。半个世纪来人们发现该病继发于多种病理状态如创伤、手术、代谢紊乱、中枢神经系统失调、前列腺素异常以及肾功能衰竭 Acute colon pseudo-obstruction or non-obstructive colon expansion (Ogilvie’s syndrome) clinical manifestations resemble the mechanical mechanical obstruction of the colon. In 1948 Ogilrie first described 2 cases of patients with extremely swollen colon, abdominal exploration found no obstruction. It has been found for half a century that the disease is secondary to a variety of pathological conditions such as trauma, surgery, metabolic disorders, central nervous system disorders, prostaglandin abnormalities, and renal failure
