摘要

目的：蠕变脂肪（CF）与克罗恩病（CD）狭窄的形成有关。本研究评估了肠道超声（IUS）对 CF 进行半定量分析的可行性，并比较了 IUS 和计算机断层扫描肠造影（CTE）之间的一致性：在这项回顾性研究中，我们招募了连续接受 IUS 和 CTE 检查的 CD 患者。对最受累肠段的 CF 包裹角进行分析，并由 IUS 和 CTE 独立评估。我们评估了病变肠道横切面和纵切面的 CF 包裹角。结果我们共招募了 96 名患者。CTE 显示 CF 包裹角为结论：IUS 对评估 CF（尤其是受影响的回肠末端和结肠患者）具有重要价值，是 CTE 的补充。IUS 是监测 CD 患者的一种无创技术：在我们的研究中，肠道 US 观察员之间以及 US 和 CT 肠道造影（CTE）之间在评估蠕变脂肪（CF）方面显示出极好的一致性，这表明超声波可以作为 CTE 的价值和补充：爬行脂肪（CF）是克罗恩病的潜在治疗靶点。超声波和 CT Enterography（CTE）在评估爬行脂肪方面显示出很好的一致性。超声波可作为 CTE 评估 CF 的补充。

Detecting and characterizing creeping fat in Crohn's disease: agreement between intestinal ultrasound and computed tomography enterography.

Objectives: Creeping fat (CF) is associated with stricture formation in Crohn's disease (CD). This study evaluated the feasibility of intestinal ultrasound (IUS) for semiquantitative analysis of CF and compared the agreement between IUS and computed tomography enterography (CTE).

Methods: In this retrospective study, we recruited consecutive CD patients who underwent IUS and CTE. CF wrapping angle was analyzed on the most affected bowel segment and was independently evaluated by IUS and CTE. We evaluated the wrapping angle of CF in the cross- and vertical sections of the diseased bowel. CF wrapping angle was divided into < 180° and ≥ 180°. IUS performance was assessed using CTE as a reference standard, and IUS interobserver consistency was evaluated.

Results: We enrolled 96 patients. CTE showed that CF wrapping angle was < 180° in 35 patients and ≥ 180° in 61 patients. We excluded three cases in which the observation positions were inconsistent between the IUS and CTE. Excellent agreement was shown between US and CTE (82/93, 88.2%). The eleven remaining cases showed inconsistencies mostly in the terminal ileum (n = 5) and small intestine (n = 4). Total agreement between IUS observers was 89.6% (86/96, κ = 0.839, p = 0.000), with perfect agreement for the ileocecal and colonic segments (35/37, 94.6% and 20/21, 95.2%, respectively) and moderate agreement for small intestinal segments (16/21, 76.2%).

Conclusions: IUS could be of value and complementary to CTE for assessing CF, particularly in patients with affected terminal ileum and colon. IUS is a non-invasive technique for monitoring CD patients.

Critical relevance statement: In our study, excellent agreement was shown between intestinal US observers as well as between US and CT enterography (CTE) for assessing creeping fat (CF), which showed that ultrasound could be of value and complementary to CTE.

Key points: Creeping fat (CF) is a potential therapeutic target in Crohn's disease. Excellent agreement was shown between US and CT Enterography (CTE) for assessing CF. Ultrasound could be complementary to CTE for assessing CF.

I³ continuously updates scientific knowledge and progress in best-practice standards in radiology through the publication of original articles and state-of-the-art reviews and opinions, along with recommendations and statements from the leading radiological societies in Europe. Founded by the European Society of Radiology (ESR), I³ creates a platform for educational material, guidelines and recommendations, and a forum for topics of controversy. A balanced combination of review articles, original papers, short communications from European radiological congresses and information on society matters makes I³ an indispensable source for current information in this field.
