摘要

目的:评估在广泛的患者人群中,包括有和没有Roux-en - Y吻合术的患者,已建立的CT征象的诊断性能和普遍性。方法:我们的机构审查委员会批准了这项回顾性研究。本文回顾了21例经手术证实为腹内疝的患者(11名女性,10名男性)和52例经CT怀疑为腹内疝但经手术排除的对照患者(23名女性,29名男性)的CT扫描结果。评估6种CT征象:肠系膜上动脉(SMA)后非十二指肠小肠(ND-SB)、适用患者右侧空肠空肠吻合、“漩涡”征、肠系膜上静脉受压、“蘑菇”征、聚集性小肠(SB)袢。使用逻辑回归计算每个症状的敏感性、特异性和95%置信区间的比值比。结果:Logistic回归发现SMA后的“蘑菇”标志、聚集性SB和ND-SB是腹内疝的显著独立预测因子,其接受者工作特征曲线下面积为0.746。SMA后的“蘑菇”征、聚集性SB和ND-SB的敏感性、特异性和比值比分别为38.1%、86.5%、3.96 (95% CI, 1.21-12.97)、47.6%、75.0%、2.73 (95% CI, 0.94-7.89)和33.3%、88.2%、3.75 (95% CI, 1.08-13.02)。结论:无论是否采用Roux-en-Y吻合,SMA后方的“蘑菇”征、聚集性SB和ND-SB都是诊断腹内疝的重要CT表现。特别是,SMA和“蘑菇”标志后面的ND-SB具有高度的特异性。

Surgery-confirmed internal hernia with or without Roux-en-Y anastomosis: diagnostic performance of six CT signs

Surgery-confirmed internal hernia with or without Roux-en-Y anastomosis: diagnostic performance of six CT signs

Surgery-confirmed internal hernia with or without Roux-en-Y anastomosis: diagnostic performance of six CT signs

Purpose

To assess the diagnostic performance and generalizability of established CT signs of internal hernias across a broad patient population including those with and without Roux-en Y anastomosis.

Methods

Our institutional review board approved this retrospective study. CT scans of 21 patients (11 women, 10 men) with surgically confirmed internal hernia and 52 control patients (23 women, 29 men) in whom internal hernia was suspected on CT but subsequently excluded surgically were reviewed. Six CT signs were evaluated: non-duodenal small bowel (ND-SB) behind the superior mesenteric artery (SMA), right-sided jejunojejunal anastomosis in applicable patients, “swirl” sign, superior mesenteric vein compression, “mushroom” sign, and clustered small bowel (SB) loops. Sensitivity, specificity, and odds ratios with 95% confidence intervals were calculated for each sign using logistic regression.

Results

Logistic regression identified the “mushroom” sign, clustered SB, and ND-SB behind the SMA as significant independent predictors of internal hernia with an area under the receiver operating characteristic curve of 0.746. The sensitivity, specificity, and odds ratio of the “mushroom” sign, clustered SB, and ND-SB behind the SMA were 38.1%, 86.5%, 3.96 (95% CI, 1.21–12.97), 47.6%, 75.0%, 2.73 (95% CI, 0.94–7.89), and 33.3%, 88.2%, 3.75 (95% CI, 1.08–13.02), respectively.

Conclusion

The “mushroom” sign, clustered SB, and ND-SB behind the SMA are valuable CT findings in diagnosing internal hernias irrespective of Roux-en-Y anastomosis. In particular, ND-SB behind the SMA and the “mushroom” sign are highly specific.

期刊介绍: Abdominal Radiology seeks to meet the professional needs of the abdominal radiologist by publishing clinically pertinent original, review and practice related articles on the gastrointestinal and genitourinary tracts and abdominal interventional and radiologic procedures. Case reports are generally not accepted unless they are the first report of a new disease or condition, or part of a special solicited section. Reasons to Publish Your Article in Abdominal Radiology: · Official journal of the Society of Abdominal Radiology (SAR) · Published in Cooperation with: European Society of Gastrointestinal and Abdominal Radiology (ESGAR) European Society of Urogenital Radiology (ESUR) Asian Society of Abdominal Radiology (ASAR) · Efficient handling and Expeditious review · Author feedback is provided in a mentoring style · Global readership · Readers can earn CME credits
