Duodenal webs represent an unusual cause of intestinal obstruction in adults. These anomalies are generally considered to be congenital in origin and usually present in infancy. However, they occasionally become symptomatic in adulthood. In these cases, because of the delay in symptoms, the etiology of duodenal webs in adults is uncertain. Gastrointestinal webs in adults have also been reported in the small intestine and colon. It is generally accepted that these lesions are an acquired defect related to long term nonsteroidal anti-inflammatory drug (NSAID) use. We report a patient with a history of long term NSAID use who presented with symptoms of gastric outlet obstruction due to the presence of a duodenal web.
十二指肠蹼是成人肠梗阻的一种罕见病因。这些异常通常被认为是先天性的，且通常在婴儿期出现。然而，它们偶尔会在成年期出现症状。在这些情况下，由于症状出现较晚，成人十二指肠蹼的病因尚不确定。成人胃肠道蹼也有在小肠和结肠被报道的情况。一般认为这些病变是与长期使用非甾体抗炎药（NSAID）相关的后天性缺陷。我们报告一例有长期使用NSAID病史的患者，该患者因十二指肠蹼而出现胃出口梗阻症状。
