Microscopic vs. endoscopic assisted harvesting and transplantation of free groin flaps: a comparative experimental...

Advances in video technology can now permit the surgeon to view a microsurgical field on a video monitor without the necessity of physically looking through the microscope eyepieces. In this project, we investigated the possibility of the performance of rat groin free-flap harvesting and transplantation with the visual assistance of the endoscope, and compared it with the conventional operating microscope, not for its replacement but as an alternative operating tool that may be preferred by a younger generation of microsurgeons or in certain operative and financial situations. Although there were not many technical differences between the microscope and the endoscope, we recorded significantly shorter operative, harvesting, and transplantation times by using the endoscope. The endoscope seems to be a promising new tool in performing microsurgery, with better handling and greater physical comfort for the surgeon. It is reliable, time-efficient, and cost-effective.
