幽门梗阻

幽门梗阻(pyloric obstruction)指的是胃的幽门部位,由于溃疡或癌瘤等病变所致的食物和胃液通过障碍。幽门梗阻是胃、十二指肠溃疡的常见并发症之一。其他可见于胃、胰腺肿瘤等。
幽门梗阻可分为不完全性梗阻和完全性梗阻两大类:
当幽门附近有溃疡或炎性病变时,便刺激幽门括约肌,引起其痉挛或幽门区水肿,由此发生的梗阻,称为幽门不完全性梗阻,或称部分性梗阻。它是暂时的,但也可有反复发作。
另外一种情况是,由于溃疡愈合后形成的瘢痕组织,或胃部手术后发生的粘连牵拉,或因癌瘤侵犯幽门窦,结果均可造成幽门区狭窄而出现梗阻,这种梗阻是很难或不能缓解的,称为完全性梗阻。
幽门梗阻为溃疡病最常见的并发症,多见于十二指肠溃疡,偶可见于幽门管或幽门前区溃疡。据统计在十二指肠溃疡中发生幽门梗阻者约占8%,而在胃溃疡中仅占2%左右。
