Abstract

Background: The ulcerative colitis intestinal ultrasound (UC-IUS) index (UII) has been reported as a sonographic scoring system correlating with the Mayo endoscopic subscore (MES). Endoscopic improvement (EI) of UC (MES ≤ 1) is a crucial therapeutic target in clinical practice. However, the cutoff value for estimating EI using the UII has not been established.

Methods: We established test and validation cohorts comprising patients with UC undergoing IUS and endoscopy within a 15-day interval at our institution. IUS findings (bowel wall thickness, bowel blood flow, bowel wall structure, haustrations, and inflammatory fat) and endoscopic activity (MES) of each colon segment (ascending, transverse, descending, and sigmoid colon) were assessed.

Results: In the test cohort (74 segments), UII was correlated with MES (r = 0.645, p < 0.0001). The median UII was 1.0 and 6.0 among participants with MES ≤ 1 and MES ≥ 2, respectively. A UII of 2 was identified as the threshold for estimating MES ≤ 1 with receiver operating characteristic analysis. In the validation cohort (122 segments), UII was correlated with MES (r = 0.675, p < 0.0001) and the estimation ability of UII ≤ 2 for EI had a positive predictive value of 85.4% and negative predictive value of 79.0%. This estimation ability of UII for EI was numerically lower but not statistically different from the previously reported Milan Ultrasound Criteria and Kyorin Ultrasound Criterion for UC.

Conclusion: UII ≤ 2 can be a simple, feasible criterion for estimating EI. Correlation with MES is an advantage of the UII compared with other criteria. Proper use of various sonographic criteria is important.

确定溃疡性结肠炎肠道超声指数的最佳临界值，以估计溃疡性结肠炎的内镜改善情况。

背景：据报道，溃疡性结肠炎肠道超声（UC-IUS）指数（UII）是一种与梅奥内镜评分（MES）相关的超声评分系统。UC 的内镜改善（EI）（MES ≤ 1）是临床实践中的一个重要治疗目标。然而，使用 UII 估算 EI 的临界值尚未确定：方法：我们建立了测试和验证队列，包括在本院接受 IUS 和内镜检查的间隔时间为 15 天的 UC 患者。我们评估了 IUS 检查结果（肠壁厚度、肠道血流、肠壁结构、肿块和炎性脂肪）以及每个结肠段（升结肠、横结肠、降结肠和乙状结肠）的内镜活动度（MES）：结果：在测试组群（74 个结肠节段）中，UII 与 MES 相关（r = 0.645，p 结论：UII ≤ 2.5%；MES ≤ 2.5%；UII ≤ 2.5%；UII ≤ 2.5%）：UII≤2 可以作为估计 EI 的一个简单可行的标准。与其他标准相比，UII 与 MES 的相关性是其优势所在。正确使用各种超声标准非常重要。
