Abstract：
UNASSIGNED: Swift identification and diagnosis of gastrointestinal infections are crucial for prompt treatment, prevention of complications, and reduction of the risk of hospital transmission. The radiological appearance on computed tomography could potentially provide important clues to the etiology of gastrointestinal infections. We aimed to describe features based on computed tomography of patients diagnosed with Campylobacter, Salmonella or Shigella infections in South Sweden.
UNASSIGNED: This was a retrospective observational population-based cohort study conducted between 2019 and 2022 in Skåne, southern Sweden, a region populated by 1.4 million people. Using data from the Department of Clinical Microbiology combined with data from the Department of Radiology, we identified all patients who underwent computed tomography of the abdomen CTA two days before and up to seven days after sampling due to the suspicion of Campylobacter, Salmonella or Shigella during the study period.
UNASSIGNED: A total of 215 CTAs scans performed on 213 patients during the study period were included in the study. The median age of included patients was 45 years (range 11-86 years), and 54% (114/213) of the patients were women. Of the 215 CTAs, 80% (n = 172) had been performed due to Campylobacter and 20% (n = 43) due to Salmonella enteritis. CTA was not performed for any individual diagnosed with Shigella during the study period. There were no statistically significant differences in the radiological presentation of Campylobacter and Salmonella infections.
UNASSIGNED: The most common location of Campylobacter and Salmonella infections was the cecum, followed by the ascending colon. Enteric wall edema, contrast loading of the affected mucosa, and enteric fat stranding are typical features of both infections. The CTA characteristics of Campylobacter and Salmonella are similar, and cannot be used to reliably differentiate between different infectious etiologies.

摘要：
■迅速识别和诊断胃肠道感染对于及时治疗至关重要，预防并发症,降低医院传播的风险。计算机断层扫描的放射学外观可能为胃肠道感染的病因提供重要线索。我们旨在描述基于计算机断层扫描诊断为弯曲杆菌的患者的特征，瑞典南部的沙门氏菌或志贺氏菌感染。
■这是一项回顾性观察性的基于人群的队列研究，于2019年至2022年在斯科恩进行，瑞典南部,一个拥有140万人口的地区。使用临床微生物学系的数据与放射科的数据相结合，我们确定了所有因怀疑弯曲杆菌而在采样前两天和采样后长达七天接受腹部CTA计算机断层扫描的患者，研究期间的沙门氏菌或志贺氏菌。
■在研究期间对213名患者进行了215次CTA扫描。纳入患者的中位年龄为45岁（范围11-86岁），54%(114/213)的患者是女性。在215个CTA中,80％（n=172）由于弯曲杆菌和20％（n=43）由于沙门氏菌肠炎。在研究期间未对任何诊断为志贺氏菌的个体进行CTA。弯曲杆菌和沙门氏菌感染的放射学表现没有统计学上的显着差异。
■弯曲杆菌和沙门氏菌感染的最常见位置是盲肠，其次是升结肠。肠壁水肿,受影响的粘膜的对比负荷，和肠脂肪绞合是两种感染的典型特征。弯曲杆菌和沙门氏菌的CTA特征相似，并且不能用于可靠地区分不同的感染病因。
