Fruitful first experience with an 8K ultra‐high‐definition endoscope for laparoscopic colorectal surgery

Abstract

We performed laparoscopic surgery for three cases of colorectal cancer using an 8K ultra‐high‐definition endoscopic system, which offers 16‐fold higher resolution than the current 2K high‐definition endoscope. The weight of the camera has been successfully reduced to 370 g. To maximize the advantages of the 8K ultra‐high‐definition endoscope, surgery was performed by darkening the room and placing a large 85‐in. display as close to the surgeon as possible. As a result, the autonomic nerve was preserved, and the membrane structure could be clearly observed. Moreover, we were able to feel the stereoscopic effect near the 3‐D image. This suggests the possibility of improved curability and function preservation with the 8K endoscope. Although there are some disadvantages that need to be overcome, the 8K ultra‐high‐definition endoscope will surely contribute to further progress in laparoscopic surgery.
