N2 - Objective 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. Design 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. Setting Numazu City Hospital in Numazu city, Japan. Participants Surgeons, instrument nurses, and medical engineers. Results 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). Conclusions 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.
