Although laparoscopic surgery has become widespread, effective and efficient education in laparoscopic surgery is difficult. Instructive laparoscopy videos with appropriate annotations are ideal for initial training in laparoscopic surgery; however, the method we use at our institution for creating laparoscopy videos with audio is not generalized, and there have been no detailed explanations of any such method. Our objectives were to demonstrate the feasibility of low-cost simple methods for recording surgical videos with audio and to perform a preliminary safety evaluation when obtaining these recordings during operations.
We devised a method for the synchronous recording of surgical video with real-time audio in which we connected an amplifier and a wireless microphone to an existing endoscopy system and its equipped video-recording device. We tested this system in 209 cases of laparoscopic surgery in operating rooms between August 2010 and July 2011 and prospectively investigated the results of the audiovisual recording method and examined intraoperative problems.

In all cases, the synchronous input of audio and video was possible. The recording system did not cause any inconvenience to the surgeon, assistants, instrument nurse, sterilized equipment, or electrical medical equipment. Statistically significant differences were not observed between the audiovisual group and control group regarding the operating time, which had been divided into 2 slots-performed by the instructors or by trainees (p > 0.05).
This recording method is feasible and considerably safe while posing minimal difficulty in terms of technology, time, and expense. We recommend this method for both surgical trainees who wish to acquire surgical skills effectively and medical instructors who wish to teach surgical skills effectively.
尽管腹腔镜手术已广泛开展，但对其进行有效且高效的教育却颇具难度。带有恰当注释的指导性腹腔镜手术视频是腹腔镜手术初始培训的理想选择；然而，我们机构用于创建带音频的腹腔镜手术视频的方法并未得到推广，也没有对此类方法的详细解释。我们的目标是证明低成本简单方法用于录制带音频的手术视频的可行性，并在手术过程中获取这些录制内容时进行初步安全性评估。
我们设计了一种同步录制手术视频与实时音频的方法，即将一个放大器和一个无线麦克风连接到现有的内镜系统及其配备的视频录制设备上。我们在2010年8月至2011年7月期间，在手术室对209例腹腔镜手术进行了该系统测试，并前瞻性地研究了视听录制方法的结果，同时检查术中问题。

在所有病例中，音频和视频的同步输入均可行。录制系统未给外科医生、助手、器械护士、消毒设备或医用电气设备带来任何不便。在由教员或学员进行操作的两个时间段的手术时间方面，视听组与对照组之间未观察到统计学上的显著差异（p>0.05）。
这种录制方法可行且相当安全，在技术、时间和费用方面难度极小。我们建议希望有效掌握手术技能的外科实习生以及希望有效教授手术技能的医学教员采用这种方法。
