Coronavirus disease 2019 (COVID-19) has posed a serious threat to global public health with its rapid spread, high fatality, and severe burden on health care providers all over the world. Although COVID-19 has been established as a respiratory tract infection, it can manifest with gastrointestinal symptoms as a consequence of direct infection by the virus or due to inflammation-mediated cytotoxicity. It has been observed that COVID-19 patients presenting with gastrointestinal symptoms tend to progress to a severe form of disease with increased morbidity and mortality, thus indicating the need for timely management. COVID-19 manifests with a wide spectrum of radiologic findings on gastrointestinal tract imaging, encompassing bowel abnormalities, hepato-biliary and pancreatic involvement, vascular occlusion, and solid organ infarction. Early recognition of these imaging features can facilitate timely treatment of COVID-19 associated gastrointestinal tract complications and may prompt the diagnosis of COVID-19 in patients with atypical disease manifestations. The aim of this article is to provide an overview of the various gastrointestinal imaging manifestations that can be encountered in patients with COVID-19, with an emphasis on early diagnosis of the disease as well as treatment related complications.
2019年冠状病毒病（COVID-19）以其快速传播、高致死率以及给全球医护人员带来的沉重负担，对全球公共卫生构成了严重威胁。尽管COVID-19已被确认为一种呼吸道感染疾病，但它可因病毒直接感染或炎症介导的细胞毒性而出现胃肠道症状。据观察，出现胃肠道症状的COVID-19患者往往会进展为重症疾病，发病率和死亡率增加，因此表明需要及时进行管理。COVID-19在胃肠道成像上表现出广泛的影像学表现，包括肠道异常、肝胆和胰腺受累、血管闭塞以及实体器官梗死。早期识别这些影像学特征有助于及时治疗COVID-19相关的胃肠道并发症，并可能促使对非典型疾病表现患者的COVID-19进行诊断。本文旨在概述COVID-19患者可能出现的各种胃肠道影像学表现，重点是疾病的早期诊断以及与治疗相关的并发症。
