摘要

背景术后胰瘘(POPF)是胃癌根治性胃切除术的一种严重并发症,主要原因是外科医生在淋巴腺切除术中偶尔会误识胰腺和脂肪。因此,本研究旨在开发一种人工智能(AI)系统,该系统能够在机器人辅助胃切除术过程中识别并突出显示胰腺。方法使用 HRNet 开发了一种胰腺识别算法,从机器人辅助胃切除术视频的 62 个场景中提取了 926 幅训练图像和 232 幅验证图像。在定量评估中,根据外科医生的基本事实和人工智能从80张测试图像中推断出的图像,计算了精确度、召回率、交集大于联合(IoU)和骰子系数。在定性评估中,10 名外科医生回答了与灵敏度和相似度有关的两个问题,以评估临床实用性。结果精确度、召回率、IoU 和 Dice 系数分别为 0.70、0.59、0.46 和 0.61。在灵敏度方面,人工智能识别胰腺的平均得分为 4.18 分(满分 5 分,1 分=识别率最低[低于 50%];5 分=识别率最高[高于 90%])。结论我们的手术人工智能系统在机器人辅助胃切除术中精确地突出了胰腺,令外科医生信服。这项技术可以防止外科医生错误识别胰腺,从而减少 POPF。

Precise highlighting of the pancreas by semantic segmentation during robot-assisted gastrectomy: visual assistance with artificial intelligence for surgeons

Background

A postoperative pancreatic fistula (POPF) is a critical complication of radical gastrectomy for gastric cancer, mainly because surgeons occasionally misrecognize the pancreas and fat during lymphadenectomy. Therefore, this study aimed to develop an artificial intelligence (AI) system capable of identifying and highlighting the pancreas during robot-assisted gastrectomy.

Methods

A pancreas recognition algorithm was developed using HRNet, with 926 training images and 232 validation images extracted from 62 scenes of robot-assisted gastrectomy videos. During quantitative evaluation, the precision, recall, intersection over union (IoU), and Dice coefficients were calculated based on the surgeons’ ground truth and the AI-inferred image from 80 test images. During the qualitative evaluation, 10 surgeons answered two questions related to sensitivity and similarity for assessing clinical usefulness.

Results

The precision, recall, IoU, and Dice coefficients were 0.70, 0.59, 0.46, and 0.61, respectively. Regarding sensitivity, the average score for pancreas recognition by AI was 4.18 out of 5 points (1 = lowest recognition [less than 50%]; 5 = highest recognition [more than 90%]). Regarding similarity, only 54% of the AI-inferred images were correctly differentiated from the ground truth.

Conclusions

Our surgical AI system precisely highlighted the pancreas during robot-assisted gastrectomy at a level that was convincing to surgeons. This technology may prevent misrecognition of the pancreas by surgeons, thus leading to fewer POPFs.
