工作背景：混合现实技术是一种新的数字全息图像技术，使用可穿戴混合现实设备在手术空间中呈现三维（3D）图像。本研究旨在评估使用全息导航系统作为术中支持图像进行腹腔镜胆囊切除术的安全性和有效性。在这项前瞻性观察性研究中，2020年4月至2020年11月，27例胆石症或轻度胆囊炎患者接受了腹腔镜胆囊切除术。9名患者使用可穿戴混合现实设备生成的3D模型进行腹腔镜胆囊切除术（3D模型腹腔镜胆囊切除术），18名患者使用传统二维图像（2D图像腹腔镜胆囊切除术）作为手术支持图像进行腹腔镜胆囊切除术。测量手术结果，如手术时间、失血量和围手术期并发症发生率，并使用四项问卷进行主观评估。所有手术均由职业生涯中期和经验丰富的surgeon.Results：腹腔镜胆囊切除术与三维模型和二维图像的中位手术时间分别为74.0和58.0分钟，分别。无术中出血和围手术期并发症发生。虽然中年外科医生表示，腹腔镜胆囊切除术的三维模型是“正常”或“容易”的二维图像相比，在所有情况下，有经验的外科医生评价三维模型更困难的9 cases.Conclusion：这项研究提供了证据，腹腔镜胆囊切除术的三维模型是可行的。然而，三维模型腹腔镜胆囊切除术的疗效可能取决于外科医生的经验，如外科医生提供的不同评级所示。(C)2021年，任作家。爱思唯尔公司出版
Background: Mixed-reality technology, a new digital holographic image technology, is used to present 3-dimensional (3D) images in the surgical space using a wearable mixed-reality device. This study aimed to assess the safety and efficacy of laparoscopic cholecystectomy using a holography-guided navigation system as an intraoperative support image. In this prospective observational study, 27 patients with cholelithiasis or mild cholecystitis underwent laparoscopic cholecystectomy between April 2020 and November 2020. Nine patients underwent laparoscopic cholecystectomy with 3D models generated by a wearable mixed-reality device (laparoscopic cholecystectomy with 3D models) and 18 underwent laparoscopic cholecystectomy with conventional two-dimensional images (laparoscopic cholecystectomy with 2D images) as surgical support images. Surgical outcomes such as operative time, blood loss, and perioperative complication rate were measured, and a four-item questionnaire was used for subjective assessment. All surgeries were performed by a mid-career and an experienced surgeon.Results: Median operative times of laparoscopic cholecystectomy with 3-dimensional models and 2-dimensional images were 74.0 and 58.0 minutes, respectively. No intraoperative blood loss or perioperative complications occurred. Although the midcareer surgeon indicated that laparoscopic cholecystectomy with 3-dimensional models was "normal" or "easy" compared with 2-dimensional images in all cases, the experienced surgeon rated 3-dimensional models as more difficult in 3 (33%) of 9 cases.Conclusion: This study provides evidence that laparoscopic cholecystectomy with 3-dimensional models is feasible. However, the efficacy of laparoscopic cholecystectomy with 3-dimensional models may depend on the surgeon's experience, as indicated by the different ratings provided by the surgeons.
