Serrated polyps are most commonly located in the colorectum and have been well recognized as an important precursor lesion for colorectal cancer. Serrated adenoma in the small intestine has been reported more rarely but may represent a distinct morphological and biological subtype with malignant potential. Here, we present the case of a 65-year-old female who underwent double-balloon enteroscopy due to obscure gastrointestinal bleeding. A polyp sized 3.5 × 2.0 cm with a long pedicle in the jejunum, located 50 cm distal to the Treitz ligament, was detected. Endoscopic mucosal resection was done. The pathological results revealed a traditional serrated adenoma sized 3.5 × 2.2 cm.
锯齿状息肉最常见于结直肠，已被公认为结直肠癌的重要前驱病变。小肠锯齿状腺瘤的报道较少，但可能代表一种具有恶性潜能的独特形态学和生物学亚型。在此，我们报告一例65岁女性因不明原因的胃肠道出血接受双气囊小肠镜检查的病例。在距Treitz韧带远端50 cm的空肠中发现一个大小为3.5×2.0 cm、有长蒂的息肉。进行了内镜黏膜切除术。病理结果显示为一个大小为3.5×2.2 cm的传统锯齿状腺瘤。
