The small intestine is a relatively privileged organ that only rarely develops malignant or even benign tumors. Given this rarity, the relative inaccessibility of the organ during routine endoscopic procedures, and the typical absence or nonspecific nature of clinical manifestations, these tumors often go undiagnosed. Treatment and prognosis are tailored to each histological subtype of tumor. This chapter will discuss the epidemiology, presentation, diagnostics, and management for the most common small bowel tumors, and will highlight the importance of recognizing patients at higher risk of small bowel neoplasia.
小肠是一个相对特殊的器官，很少发生恶性肿瘤，甚至良性肿瘤也很少见。鉴于这种罕见性、在常规内镜检查过程中该器官相对难以触及，以及临床表现通常缺乏或具有非特异性，这些肿瘤常常未被诊断出来。治疗和预后是根据肿瘤的每种组织学亚型来定制的。本章将讨论最常见的小肠肿瘤的流行病学、临床表现、诊断和管理，并将强调识别小肠肿瘤发生风险较高患者的重要性。
