The Global Operative Assessment of Laparoscopic Skill (GOALS) is one validated metric utilized to grade laparoscopic skills and has been utilized to score recorded operative videos. To facilitate easier viewing of these recorded videos, we are developing novel techniques to enable surgeons to view these videos. The objective of this study is to determine the feasibility of utilizing widespread current consumer-based technology to assist in distributing appropriate videos for objective evaluation.
Videos from residents were recorded via a direct connection from the camera processor via an S-video output via a cable into a hub to connect to a standard laptop computer via a universal serial bus (USB) port. A standard consumer-based video editing program was utilized to capture the video and record in appropriate format. We utilized mp4 format, and depending on the size of the file, the videos were scaled down (compressed), their format changed (using a standard video editing program), or sliced into multiple videos. Standard available consumer-based programs were utilized to convert the video into a more appropriate format for handheld personal digital assistants. In addition, the videos were uploaded to a social networking website and video sharing websites.
Recorded cases of laparoscopic cholecystectomy in a porcine model were utilized. Compression was required for all formats. All formats were accessed from home computers, work computers, and iPhones without difficulty. Qualitative analyses by four surgeons demonstrated appropriate quality to grade for these formats.
Our preliminary results show promise that, utilizing consumer-based technology, videos can be easily distributed to surgeons to grade via GOALS via various methods. Easy accessibility may help make evaluation of resident videos less complicated and cumbersome.
全球腹腔镜手术技能评估（GOALS）是一种经过验证的用于分级腹腔镜技能的指标，已被用于对记录的手术视频进行评分。为了更方便地观看这些记录的视频，我们正在开发新的技术，使外科医生能够观看这些视频。本研究的目的是确定利用广泛的现有消费者技术来协助分发用于客观评估的适当视频的可行性。
通过摄像头处理器的直接连接，通过 S 视频输出，通过电缆连接到集线器，再通过通用串行总线（USB）端口连接到标准笔记本电脑，记录住院医师的视频。使用标准的消费者视频编辑程序捕获视频并以适当的格式进行记录。我们使用 mp4 格式，根据文件的大小，对视频进行缩放（压缩）、更改格式（使用标准视频编辑程序）或分割成多个视频。使用标准的可用消费者程序将视频转换为更适合手持个人数字助理的格式。此外，还将视频上传到社交网络网站和视频共享网站。
使用腹腔镜胆囊切除术猪模型记录了手术案例。所有格式都需要压缩。来自家庭电脑、工作电脑和 iPhone 的所有格式都可以轻松访问。四位外科医生的定性分析表明，这些格式的分级质量适当。
我们的初步结果表明，利用消费者技术，可以通过各种方法，通过 GOALS 轻松地将视频分发给外科医生进行评分。易于访问可能有助于使住院医师视频的评估变得不那么复杂和繁琐。
