摘要

由于多种原因,急腹症主诉占肿瘤患者急诊科(ED)的40%。小肠病理呈现一个诊断挑战,由于其多样化的范围和经常重叠的临床表现。在肿瘤患者中,由于肿瘤生长、手术和治疗效果引起的结构改变会使诊断过程进一步复杂化。由于免疫系统较弱,肿瘤患者也极易受到胃肠道感染(GIT)。传统的计算机断层扫描(CT)被用作金标准诊断方式。然而,三维(3D)后处理技术,包括最大强度投影(MIP),体绘制(VR)和电影渲染(CR)已被用于辅助图像评估。为了平衡和有组织的方法来描述这一复杂人群的诊断挑战,我们将图画文章分为两部分。第一部分的重点是肿瘤和感染相关的原因,总结如下的视觉摘要。第二部分将讨论治疗相关的并发症,包括化疗、放疗、免疫治疗、移植物抗宿主病和术后并发症。

Imaging of acute small bowel pathologies in oncology patients in the ER part I: the role of Computed Tomography (CT) for the evaluation of Tumor and infections.

Acute abdominal complaints constitute up to 40% of all emergency department (ED) presentations in oncology patients due to a multitude of causes. Small bowel pathologies present a diagnostic challenge due to their diverse range and frequently overlapping clinical presentation. In oncology patients, structural changes resulting from tumor growth, surgery and treatment effects can further complicate the diagnostic process. Due to a weakened immune system, oncology patients are also highly susceptible to infections of the gastrointestinal tract (GIT). Traditional computed tomography (CT) scans are used as the gold standard diagnostic modality. However, three-dimensional (3D) postprocessing techniques including maximal intensity projection (MIP), volume rendering (VR) and cinematic rendering (CR) have been employed to aid image evaluation. For a balanced and organized approach to describe diagnostic challenges in this complex population, we have divided the pictorial essay into two parts. The first part focuses on tumor- and infection-associated causes, as summarized below in the visual abstract. The second part will address treatment-related complications, including chemotherapy, radiotherapy, immunotherapy, graft-versus-host disease and post-surgical complications.
