Certain open surgical procedures are difficult to observe, and poor visualization of the surgical field results in a compromised teaching environment for residents and medical students. In an attempt to improve the visualization of the open surgical field, we performed an open surgical procedure while viewing it via a laparoscope mounted to the side of the operating room table with an alpha port. These images were then compared in a blinded fashion with images from a boom-mounted camera positioned above the surgical field and a head-mounted camera positioned on the operating surgeon.
Participants viewed all 3 images from a remote location in a blinded, random fashion. All participants then completed a Likert questionnaire evaluating each image.
Fourteen participants were in the study. The alpha port/laparoscope image was superior to the head-cam image in all 8 categories. The alpha port/laparoscope image was superior to the sky-cam image in 4 of 8 categories. All 14 participants felt the alpha port/laparoscope image would benefit surgical education
Use of a laparoscope mounted via an alpha port to an operating room table provides superior images during open surgery. This provides a unique and affordable way to teach residents and medical students operative procedures that are otherwise difficult to view.
某些开放式外科手术难以观察，手术视野的可视性差会导致住院医师和医学生的教学环境不佳。为了改善开放式手术视野的可视性，我们在通过安装在手术台一侧带有α端口的腹腔镜观察的同时进行了开放式外科手术。然后将这些图像与位于手术视野上方的悬臂式摄像头和位于主刀医生头部的头戴式摄像头拍摄的图像进行盲法比较。
参与者以盲法、随机方式从远程位置查看所有3张图像。然后，所有参与者完成一份李克特问卷，对每张图像进行评估。
14名参与者参与了该研究。在所有8个类别中，α端口/腹腔镜图像均优于头戴式摄像头图像。在8个类别中的4个类别中，α端口/腹腔镜图像优于悬臂式摄像头图像。所有14名参与者都认为α端口/腹腔镜图像将有益于外科教育。
通过α端口将腹腔镜安装在手术台上，在开放式手术中可提供更好的图像。这为教授住院医师和医学生那些原本难以观察的手术操作提供了一种独特且经济实惠的方法。
