Background:
Laparoscopy has familiarized most surgeons with the benefits of a surgical video system, including the ability to magnify fine structures, to display the operative field on a monitor for improved intraoperative communication, and to capture video footage for documentation and education. Use of intraoperative video systems during open surgery is far less common and the potential benefits of this have not been well explored. In this report we describe a simple video system that is applicable to both laparoscopic and open surgery.
Methods:
We employed a standard laparoscopic HD camera (1080p) and telescope for initial laparoscopy. In cases requiring laparotomy, a mechanical arm is attached to the operating table and the camera is mounted without the telescope; this provides video display of the open surgical field. In cases requiring dissection or anastomosis of minute structures, a prototype telescope made for open cases is attached to the same camera; this provides improved magnification and illumination for the surgeon. Microsurgical components can then proceed with the surgeon working off the video monitor at a more convenient posture and with the benefits of video display.
Results:
This multifunctional HD video system for open abdominal surgery has been utilized in 98 complex hepatopancreaticobiliary surgeries. Clear benefits include (1) improved intraoperative communication, (2) improved teaching of bystanders, (3) improved visualization of minute structures, and (4) improved capture and utilization of surgical video and images for education. In an analysis of patients who underwent pancreaticoduodenectomy (PD) with this system, there was a trend toward fewer pancreatic leaks and shorter length of stay but slightly longer operative time compared to PD prior to implementation of this system.
Conclusions:
This system can be employed with little added cost over a standard laparoscopy setup and has the potential to be widely utilized in surgical education programs.
