摘要

机器人远端胃切除术(RDG)的复杂性使我们有理由对医生的手术技能进行评估。不同水平的手术技能会影响患者的预后。我们旨在研究如何利用新型人工智能(AI)模型,通过识别手术器械来评估 RDG 的手术技能。我们使用了多级时空卷积网络 Deeplab,并在 1234 张人工标注的图像上进行了训练。然后在 149 张注释图像上测试了模型的准确性。我们标注了 540 把卡迪尔镊子、898 把瘘管双刀、359 把吸管、307 把马里兰双刀、688 把谐波手术刀、400 把订书机和 59 把大夹子。平均 IoU 和准确率分别为 0.82 ± 0.12 和 87.2 ± 11.9%。此外,还比较了每种器械的使用时间占人工智能预测的幽门下淋巴腺切除术总时间的百分比。与无经验组相比,有经验组使用订书机和大夹子的时间明显更短。这项研究首次报道了人工智能模型可以成功、准确地确定 RDG 的手术技巧。我们的人工智能让我们有办法识别并自动生成该手术中手术器械的实例分割。利用这项技术,可以无偏见地、更容易地掌握 RDG 手术技能。

Evaluating surgical expertise with AI-based automated instrument recognition for robotic distal gastrectomy

Evaluating surgical expertise with AI-based automated instrument recognition for robotic distal gastrectomy

Introduction

Complexities of robotic distal gastrectomy (RDG) give reason to assess physician's surgical skill. Varying levels in surgical skill affect patient outcomes. We aim to investigate how a novel artificial intelligence (AI) model can be used to evaluate surgical skill in RDG by recognizing surgical instruments.

Methods

Fifty-five consecutive robotic surgical videos of RDG for gastric cancer were analyzed. We used Deeplab, a multi-stage temporal convolutional network, and it trained on 1234 manually annotated images. The model was then tested on 149 annotated images for accuracy. Deep learning metrics such as Intersection over Union (IoU) and accuracy were assessed, and the comparison between experienced and non-experienced surgeons based on usage of instruments during infrapyloric lymph node dissection was performed.

Results

We annotated 540 Cadiere forceps, 898 Fenestrated bipolars, 359 Suction tubes, 307 Maryland bipolars, 688 Harmonic scalpels, 400 Staplers, and 59 Large clips. The average IoU and accuracy were 0.82 ± 0.12 and 87.2 ± 11.9% respectively. Moreover, the percentage of each instrument's usage to overall infrapyloric lymphadenectomy duration predicted by AI were compared. The use of Stapler and Large clip were significantly shorter in the experienced group compared to the non-experienced group.

Conclusions

This study is the first to report that surgical skill can be successfully and accurately determined by an AI model for RDG. Our AI gives us a way to recognize and automatically generate instance segmentation of the surgical instruments present in this procedure. Use of this technology allows unbiased, more accessible RDG surgical skill.
