探讨CT小肠造影对克罗恩病的诊断评估价值。

选择2021年7月至2023年7月江苏省苏北人民医院收治的明确诊断为小肠克罗恩病的80例患者作为研究对象，采用CT小肠造影检查诊断。分析CT小肠造影诊断结果，造影病变部位检查结果，活动期与缓解期肠壁增厚情况对比，有无木梳征情况下静脉期肠壁CT值、肠壁厚度、肠壁分层样强化、肠壁均匀强化。

（1）经CT小肠造影诊断，76例诊断准确，诊断符合率为95.00%（76/80），病症包括：肠腔狭窄、网膜炎、腹腔脓肿、肠壁分层、肠壁厚度增加及强化、木梳征以及淋巴结肿大、瘘管等；（2）CT小肠造影病变部位主要在回肠末端、单纯回肠、结肠与回肠、空肠与回肠，位于回肠末端占61.84%；（3）活动期CD肠壁厚度显著大于缓解期CD（P<0.05）；（4）有无木梳征情况下静脉期肠壁CT值、肠壁厚度、肠壁分层样强化、肠壁均匀强化比较，差异均有统计学意义（P均<0.05）。

CT小肠造影对克罗恩病具有较高的诊断准确率，能够清晰显示患者肠壁病变情况，为临床治疗提供参考依据。

To explore the diagnostic and evaluation value of CT enterography for Crohn's disease.

A total of 80 patients with clear diagnosis of small intestinal Crohn's disease admitted to Northern Jiangsu People's Hospital of Jiangsu Province from July 2021 to July 2023 were selected as the study subjects, and CT enterography was used for diagnosis. The diagnostic results of CT enterography, the examination results of the lesion site, the comparison of intestinal wall thickening between active and remission stages, the CT value of intestinal wall in the vein phase with or without wooden comb sign, intestinal wall thickness, stratified enhancement of intestinal wall, homogeneous enhancement of intestinal wall were analyzed.

(1) CT enterography showed that 76 cases were diagnosed accurately, with a diagnostic accuracy rate of 95.00% (76/80). Specific symptoms included: intestinal stenosis, omental inflammation, abdominal abscess, intestinal wall stratification, increased and enhanced intestinal wall thickness, wooden comb sign, lymph node enlargement, fistula, etc; (2) The main lesion sites of CT small intestine imaging included: the distal end of the ileum, simple ileum, colon and ileum, jejunum and ileum, with the main site located at the distal end of the ileum (61.84%); (3) The intestinal wall thickness of Crohn's disease during the active phase was significantly greater than that during the remission phase (P<0.05); (4) There were statistically significant differences in CT values, intestinal wall thickness, stratified enhancement and homogeneous enhancement of intestinal wall in the vein phase with or without the wooden comb sign (all P<0.05).

CT enterography has a high diagnostic accuracy for Crohn's disease and can clearly display the condition of intestinal wall lesions in patients, providing important reference basis for clinical treatment.
