Advantage of Using 8K Ultra-High-Definition Television System for Kasai Portoenterostomy for Biliary Atresia

Abstract

Kasai portoenterostomy (KPE) is currently the first-line treatment for biliary atresia. Many pediatric surgeons have reported that the dissection of the fibrous remnant at the porta hepatis is one of the most important components of this procedure. Furthermore, laparoscopic portoenterostomy is being increasingly used to treat biliary atresia.An advantage of laparoscopic surgery is that surgeons can more easily identify microbiliary ducts, owing to the magnification. We report the case of a 61-day-old girl on whom we performed an exploratory laparotomy and diagnosed type III biliary atresia using intraoperative cholangiography. For the first time, we performed an open KPE using an 8K ultra-high-definition television system. This allowed us to clearly view the porta hepatis and to successfully perform the portoenterostomy.

A multicenter survey of effects and challenges of an 8K ultra‐high‐definition endoscopy system compared to existing endoscopy systems for endoscopic surgery

“…In clinical experience, 8K UHD images have been reported to provide a high degree of tissue recognition, making it easy to distinguish fine tissue structures and comprehend their morphology 6,7,11 . Colorectal surgery was the most performed surgery in this study.…”

“…In clinical experience, 8K UHD images have been reported to provide a high degree of tissue recognition, making it easy to distinguish fine tissue structures and comprehend their morphology. 6,7,11 Colorectal surgery was the most performed surgery in this study. It was reported that autonomic nerves, microvascular networks, and membrane structures were identified as anatomical structures that were more accurately visualized by the 8K UHD images, and identifying these structures accurately could be useful for cancer curability and preservation of organ function in colorectal surgery.…”

“…[1][2][3][4][5] 8K UHD images, which have four times as many pixels as 4K UHD due to innovations in video technology, will enable even clearer recognition of anatomical structures and are expected to contribute to the further development of surgical techniques and advanced applications in various fields of endoscopic surgery or microsurgery. [6][7][8][9][10] Laparoscopic cholecystectomy using 8K UHD was performed for the first time in 2014. 11 At that time, a 2.2-kg 8K camera head was used, but an 8K endoscopy system was later developed with camera head that was significantly smaller, lighter, and had improved sensitivity, and pharmaceutical approval was obtained as a medical device in 2017.…”

“…Detailed image information obtained from endoscopy is especially important in endoscopic surgery, and three‐dimensional (3D) full‐high‐definition (FHD) and 4K ultra‐high‐definition (UHD) systems are now becoming widespread, enabling more accurate procedures 1–5 . 8K UHD images, which have four times as many pixels as 4K UHD due to innovations in video technology, will enable even clearer recognition of anatomical structures and are expected to contribute to the further development of surgical techniques and advanced applications in various fields of endoscopic surgery or microsurgery 6–10 …”
