Small-bowel tumors represent a rare entity comprising 0.6% of all new cancer cases in the US, and only 3% of all gastrointestinal neoplasms. They are a heterogenous group of neoplasms comprising of about forty different histological subtypes with the most common being adenocarcinoma, neuroendocrine tumors, stromal tumors and lymphomas. Their incidence has been reportedly increasing over recent years, partly owing to the advances and developments in the diagnostic modalities. Small-bowel capsule endoscopy, device assisted enteroscopy and dedicated small-bowel cross-sectional imaging are complimentary tools, supplementing each other in the diagnostic process. Therapeutic management of small-bowel tumors largely depends on the histological type and staging at diagnosis. The aim of the present review article is to discuss relevant advances in the diagnosis and management of small-bowel tumors.

小肠肿瘤是一种罕见的肿瘤，占美国所有新发癌症病例的 0.6%，仅占所有胃肠道肿瘤的 3%。它们是一组异质肿瘤，由约四十种不同的组织学亚型组成，最常见的是腺癌、神经内分泌肿瘤、间质瘤和淋巴瘤。据报道，近年来其发病率不断增加，部分原因是诊断方式的进步和发展。小肠胶囊内窥镜、设备辅助小肠镜和专用小肠横断面成像是互补的工具，在诊断过程中相互补充。小肠肿瘤的治疗管理很大程度上取决于组织学类型和诊断时的分期。本综述文章的目的是讨论小肠肿瘤诊断和治疗的相关进展。
