Abstract

Purpose: Gastrointestinal (GI) dilatations are frequently observed in radiographs of pediatric patients who visit emergency departments with acute symptoms such as vomiting, pain, constipation, or diarrhea. Timely and accurate differentiation of whether there is an obstruction requiring surgery in these patients is crucial to prevent complications such as necrosis and perforation, which can lead to death. In this study, we aimed to use convolutional neural network (CNN) models to differentiate healthy children with normal intestinal gas distribution in abdominal radiographs from those with GI dilatation or obstruction. We also aimed to distinguish patients with obstruction requiring surgery and those with other GI dilatation or ileus.

Methods: Abdominal radiographs of patients with a surgical, clinical, and/or laboratory diagnosis of GI diseases with GI dilatation were retrieved from our institution's Picture Archiving and Communication System archive. Additionally, abdominal radiographs performed to detect abnormalities other than GI disorders were collected to form a control group. The images were labeled with three tags according to their groups: surgically-corrected dilatation (SD), inflammatory/infectious dilatation (ID), and normal. To determine the impact of standardizing the imaging area on the model's performance, an additional dataset was created by applying an automated cropping process. Five CNN models with proven success in image analysis (ResNet50, InceptionResNetV2, Xception, EfficientNetV2L, and ConvNeXtXLarge) were trained, validated, and tested using transfer learning.

Results: A total of 540 normal, 298 SD, and 314 ID were used in this study. In the differentiation between normal and abnormal images, the highest accuracy rates were achieved with ResNet50 (93.3%) and InceptionResNetV2 (90.6%) CNN models. Then, after using automated cropping preprocessing, the highest accuracy rates were achieved with ConvNeXtXLarge (96.9%), ResNet50 (95.5%), and InceptionResNetV2 (95.5%). The highest accuracy in the differentiation between SD and ID was achieved with EfficientNetV2L (94.6%).

Conclusion: Deep learning models can be integrated into radiographs located in the emergency departments as a decision support system with high accuracy rates in pediatric GI obstructions by immediately alerting the physicians about abnormal radiographs and possible etiologies.

Clinical significance: This paper describes a novel area of utilization of well-known deep learning algorithm models. Although some studies in the literature have shown the efficiency of CNN models in identifying small bowel obstruction with high accuracy for the adult population or some specific diseases, our study is unique for the pediatric population and for evaluating the requirement of surgical versus medical treatment.

卷积神经网络算法在儿童常规x线片上区分胃肠道梗阻的诊断准确性。
目的:胃肠(GI)扩张经常在急诊儿科患者的x线片上观察到,这些患者有急性症状,如呕吐、疼痛、便秘或腹泻。及时准确地鉴别这些患者是否存在需要手术治疗的梗阻,对于预防可导致死亡的坏死和穿孔等并发症至关重要。在这项研究中,我们旨在使用卷积神经网络(CNN)模型来区分腹部x线片上肠道气体分布正常的健康儿童与胃肠道扩张或梗阻的健康儿童。我们还旨在区分需要手术的梗阻患者和其他胃肠道扩张或肠梗阻患者。方法:从我院的图片存档和通信系统档案中检索经手术、临床和/或实验室诊断为消化道疾病并伴有消化道扩张的患者的腹部x线片。此外,收集腹部x线片以检测除胃肠道疾病外的异常,形成对照组。图像按组标记三种标签:手术矫正扩张(SD),炎症/感染性扩张(ID)和正常。为了确定标准化成像区域对模型性能的影响,通过应用自动裁剪过程创建了一个额外的数据集。使用迁移学习训练、验证和测试了在图像分析方面取得成功的五个CNN模型(ResNet50、InceptionResNetV2、Xception、EfficientNetV2L和ConvNeXtXLarge)。结果:正常540例,SD 298例,ID 314例。在正常和异常图像的区分中,ResNet50(93.3%)和InceptionResNetV2 (90.6%) CNN模型的准确率最高。采用自动裁剪预处理后,ConvNeXtXLarge(96.9%)、ResNet50(95.5%)和InceptionResNetV2(95.5%)的准确率最高。在区分SD和ID方面,效率netv2l的准确率最高(94.6%)。结论:将深度学习模型集成到急诊科的x线片中,可以立即提醒医生异常x线片和可能的病因,作为儿科消化道梗阻的决策支持系统,准确率很高。临床意义:本文描述了一个利用知名深度学习算法模型的新领域。尽管已有文献表明CNN模型在成人或某些特定疾病中识别小肠梗阻的准确性较高,但我们的研究对于儿科人群以及评估手术与药物治疗的需求是独一无二的。
