Pulmonary imaging finding of Coronavirus disease 2019 (COVID-19) has been widely described, but until now few studies have been published about abdominal radiological presentation. The aim of this study was to provide an overview of abdominal imaging findings in patients with COVID-19 in a multicenter study and correlate them with worse clinical outcomes.
This retrospective study included adult COVID-positive patients with abdominal CT performed from 4/1/2020 to 5/1/2020 from two institutions. Demographic, laboratory and clinical data were recorded, including clinical outcomes.
Of 81 COVID-positive patients, the average age was 61 years, 42 (52%) women and 45 (55%) had positive abdominopelvic findings. The most common abdominal imaging features were intestinal imaging findings (20/81, 24%), including colorectal (4/81, 5%) and small bowel thickening (10/81, 12%), intestinal distension (15/81, 18%), pneumatosis (1/81, 1%) and intestinal perforation (1/81, 1%). On multivariate analysis, intestinal imaging findings were associated with higher risk of worse outcome (death or invasive mechanical ventilation) (RR = 2.6, p = 0.04) and higher risk of invasive mechanical ventilation alone (RR = 6.2, p = 0.05).
Intestinal abnormalities were common findings in COVID-19 patients who underwent abdominal CT and were significantly correlated to worse outcomes in the clinical follow-up.
2019冠状病毒病（COVID-19）的肺部影像学表现已被广泛描述，但迄今为止，关于腹部放射学表现的研究报道较少。本研究的目的是在一项多中心研究中概述COVID-19患者的腹部影像学表现，并将其与更差的临床结局相关联。
这项回顾性研究纳入了2020年4月1日至2020年5月1日期间在两家机构接受腹部CT检查的成年COVID阳性患者。记录了人口统计学、实验室和临床数据，包括临床结局。
在81例COVID阳性患者中，平均年龄为61岁，42例（52%）为女性，45例（55%）有腹部盆腔阳性发现。最常见的腹部影像学特征是肠道影像学表现（20/81，24%），包括结肠增厚（4/81，5%）和小肠增厚（10/81，12%）、肠扩张（15/81，18%）、积气（1/81，1%）和肠穿孔（1/81，1%）。多因素分析显示，肠道影像学表现与更差结局（死亡或有创机械通气）的风险较高相关（RR = 2.6，p = 0.04），与单独有创机械通气的风险较高相关（RR = 6.2，p = 0.05）。
肠道异常是接受腹部CT检查的COVID-19患者的常见表现，并且在临床随访中与更差的结局显著相关。
