Abstract

We could successfully develop a handy 8K ultra-high definition (UHD) camera which was combined with an optically advanced rigid endoscope and an 85-inch 8K UHD display. For the past 3 years, we have clinically performed endoscopic cholecystectomy uneventfully in a total of 6 adult patients having symptomatic gallstone disease. The 8K UHD imaging could give us a visual acuity of 4.27 and a 16-fold higher resolution (33,000,000 pixels) as compared with that of a currently employed 2K high definition (HD) imaging (2,000,000 pixels). In our clinical practice, the 8K UHD endoscope offered surgeons an outstanding quality of vision with a sense of presence as well as a feeling of real solid things with detailed pin-sharp, true-to-life, and 3-D like images. Importantly enough, these imaging qualities are sure to enable us much more sharp accurate procedures including dissection or anastomosis of minute blood vessels or nerve fibers. We should emphasize here that these capabilities are required most to accomplish surgical intervention for susceptible fragile tissues of small pediatric patients. There are still a couple of problems to be overcome, the 8K UHD endoscope is sure to be quite promising technology for general along with pediatric surgery which should be safer, faster, and less expensive.
