METHODS: This report describes the case of a middle-aged man initially suspected of having acute appendicitis, which rapidly progressed to acute peritonitis with concomitant intestinal obstruction observed during preoperative assessment. Surgical exploration confirmed the diagnosis of Meckel\'s diverticulum-induced internal hernia, accompanied by intestinal obstruction and necrosis. In addition, the hernial ring base exhibited entrapment resembling a surgical knot.
CONCLUSIONS: Meckel\'s diverticulum is a rare cause of small bowel obstruction in adults, and it should be considered in a differential diagnosis.
方法:本报告描述了一名最初怀疑患有急性阑尾炎的中年男子的病例,术前评估中观察到急性腹膜炎并伴有肠梗阻。手术探查证实诊断为Meckel憩室诱发的内疝,伴有肠梗阻和坏死。此外,疝环基部表现出类似于手术结的截留。
结论:Meckel憩室是成人小肠梗阻的罕见原因,在鉴别诊断中应该考虑。
