Objective

To determine the ability of multidetector computed tomography (MPR-MDCT) to identify and classify the juxtapapillary duodenal diverticulum (JPDD), with ERCP findings as the gold standard.

Methods

We retrospectively reviewed all ERCP examinations (n: 455) performed between January 2010 to December 2018 and selected 105 patients with JPDD as the inclusion criteria. Of those, 28 patients were excluded because of advanced pancreatic carcinoma, incomplete MDCT examinations and biliary catheter insertion. Finally, MDCT examinations of 77 patients with JPDD were assessed for the presence and type of JPDD.

Results

MPR-MDCT was able to identify 71 (92.2%) JPDD in 77 cases with 88.9% accuracy, 83.3% sensitivity, and 91.6% specificity in classifying the type of JPDD. MPR-MDCT performed best in determining type 1 JPDD, with accuracy of 95.4% compared with type 2 (83.3%) and type 3 (87.8%). There was no significant difference between age, gender, incidence of biliary stones and pancreatitis between each type of JPDD. No correlation of sizes with types of JPDD was found.

Conclusions

MPR-MDCT can accurately identify and classify JPDD. This information will be useful in determining the difficulty of ERCP.

在 MDCT 中使用多平面重建评估近乳头状十二指肠憩室：与 ERCP 发现的相关性。

客观的

确定多探测器计算机断层扫描 (MPR-MDCT) 识别和分类近乳头十二指肠憩室 (JPDD) 的能力，以 ERCP 发现作为金标准。

方法

我们回顾性回顾了2010 年 1 月至 2018 年 12 月期间进行的所有 ERCP 检查（n：455），并选择了 105 名 JPDD 患者作为纳入标准。其中，28 名患者因晚期胰腺癌、MDCT 检查不完整和胆管插入而被排除在外。最后，对 77 名 JPDD 患者的 MDCT 检查评估了 JPDD 的存在和类型。

结果

MPR-MDCT 能够在 77 例病例中识别 71（92.2%）个 JPDD，准确度为 88.9%，敏感性为 83.3%，在分类 JPDD 类型时特异性为 91.6%。MPR-MDCT 在确定 1 型 JPDD 方面表现最好，与 2 型（83.3%）和 3 型（87.8%）相比，准确率为 95.4%。各类型 JPDD 的年龄、性别、胆道结石发生率和胰腺炎的发生率无显着差异。没有发现大小与 JPDD 类型之间的相关性。

结论

MPR-MDCT 可以准确识别和分类 JPDD。此信息将有助于确定 ERCP 的难度。
