Abstract

There is a high burden of acute abdomen presentations in oncology patients, stemming from tumor development, surgical interventions, and the side effects of treatments on the gastrointestinal tract. Chemotherapy, radiotherapy and postsurgical complications have previously been shown to affect the small bowel; however, newer modalities of cancer treatment including immunotherapy and antiangiogenic therapy have also been seen to cause bowel injury. 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 utilized for image interpretation. For a more organized approach to describe diagnostic challenges in this complex population, we have divided the pictorial essay into two parts. The first part focused on tumor- and infection-associated causes. This second part will address treatment-related complications, including chemotherapy, radiotherapy, immunotherapy, graft-versus-host disease and post-surgical complications as summarized below.

急诊肿瘤患者急性小肠病变的影像学第二部分:计算机断层扫描(CT)在检测治疗相关小肠并发症中的作用。
由于肿瘤的发展、手术干预以及治疗对胃肠道的副作用,肿瘤患者出现急腹症的负担很高。化疗、放疗和术后并发症先前已被证明会影响小肠;然而,包括免疫疗法和抗血管生成疗法在内的新的癌症治疗方式也被认为会导致肠道损伤。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)已被用于图像解释。为了更有组织地描述这个复杂人群的诊断挑战,我们将图画文章分为两个部分。第一部分着重于肿瘤和感染相关的原因。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、移植物抗宿主病和手术后并发症,总结如下。
