Diverticular bleeding of the small bowel is rare and occurs primarily in adults aged more than 60 years. In younger adults, Meckel's diverticulum, a true diverticulum that congenitally occurs in the distal ileum, is the most common cause of diverticular bleeding of the small bowel. Unlike Meckel's diverticula, other kinds of small bowel diverticula are not congenital and their incidence is related to age. Furthermore, congenital true diverticular bleeding of the jejunum in adults is very rare. We report the case of a 24-year-old man with subepithelial tumor-like lesion accompanied with obscure overt gastrointestinal bleeding. This lesion was initially suspected to be a subepithelial tumor based on radiologic tests and capsule endoscopy. He was finally diagnosed with a congenital true diverticulum in the jejunum with the appearance of a Meckel's diverticulum after surgical resection.
小肠憩室出血较为罕见，主要发生在60岁以上的成年人中。在较年轻的成年人中，梅克尔憩室是小肠憩室出血最常见的原因，梅克尔憩室是一种先天性发生在回肠远端的真性憩室。与梅克尔憩室不同，其他类型的小肠憩室并非先天性，其发病率与年龄有关。此外，成人空肠先天性真性憩室出血非常罕见。我们报告了一例24岁男性患者，其患有上皮下肿瘤样病变并伴有隐匿性显性胃肠道出血。基于放射学检查和胶囊内镜检查，该病变最初被怀疑为上皮下肿瘤。手术切除后，最终诊断为具有梅克尔憩室外观的空肠先天性真性憩室。
