摘要

背景:外科纱布常用于腹腔镜手术。然而,由于纱布的体积小,肉眼可见性有限,触觉不明显,在手术中很容易被忽视。目的:为了支持外科医生检测纱布,降低遗漏风险,提高手术安全性和效率,我们开发了一个旨在识别腹腔镜肝脏手术纱布的深度学习框架。方法:收集2家医院的腹腔镜肝脏手术视频共33段,作为内外部数据集。深度学习模型在单个视频帧上进行训练,以检测和分割纱布,每帧包含一个或多个纱布对象。为了更好地评估模型的性能,我们引入了一种定量方法,将纱布检测难度分为容易、中等和困难三类。使用两个中心的数据评估不同类别的模型性能。结果:在被测模型中,YOLOv8n对纱布的检测准确率最高。在内部测试集中,召回率和精确率分别达到0.8443和0.9034,而在外部测试集中,召回率和精确率分别达到0.8289和0.9103。对于纱布分割,FCN-ResNet101模型表现出更优异的性能,在内部测试集的Dice得分为0.9389,在外部测试集的Dice得分为0.9081。结论:研究结果强调了所提出的框架在腹腔镜肝脏手术视频中检测和分割不同背景复杂性的纱布的强大能力。这种方法有可能显著改善手术期间纱布的管理。

Gauze detection and segmentation in laparoscopic liver surgery: a multi-center study.

Background: Surgical gauze is commonly used in laparoscopic procedures. However, due to its small size, limited visibility to the naked eye, and subtle tactile presence, gauze can easily be overlooked during surgery.

Purpose: To support surgeons in detecting gauze, reduce the risk of omission, and enhance surgical safety and efficiency, we developed a deep learning framework designed to identify gauze in laparoscopic liver surgeries.

Methods: In total, 33 laparoscopic liver surgery videos were collected from 2 hospitals and used as internal and external datasets. Deep learning models were trained on individual video frames to detect and segment gauze, with each frame containing one or more gauze objects. To better evaluate model performance, we introduced a quantitative approach that classified gauze detection difficulty into three categories: easy, moderate, and difficult. Model performance across categories was assessed using data from both centers.

Results: Among the tested models, YOLOv8n achieved the highest accuracy in gauze detection. In the internal test set, recall and precision reached 0.8443 and 0.9034, while in the external test set, they were 0.8289 and 0.9103. For gauze segmentation, the FCN-ResNet101 model demonstrated superior performance, achieving Dice scores of 0.9389 in the internal test set and 0.9081 in the external test set.

Conclusion: The findings highlight the strong capability of the proposed framework to detect and segment gauze across varying levels of background complexity in laparoscopic liver surgery videos. This approach has the potential to significantly improve gauze management during surgery.
