Case Study N°1 Effectiveness of OPELAIII in Gastroentrological Surgery - 1

Wearable Surgical Lighting System in Open Surgery Professor at Department of Gastroenterological Surgery, Yokohama City University School of Medicine OPELAI is a wearable surgical lighting system launched in Japan in October 201 7 developed to realize high-quality light while minimizing shadows and providing ease of movement and comfort. These are interviews with leading doctors in various fields where they talk about the effectiveness of OPELAHI in open surgery. The first visit was to Dr. Itaru Endo of Yokohama City University. He talks about his experience with OPELAI in surgery for bile duct cancer. I used OPELAEI in the case of hilar cholangiocarcinoma, where we resected the central two segments of inner and anterior segments of the liver and also the caudate lobe located deep in the organ. Open surgery for hepatobiliary and pancreatic areas involves many procedures in areas that are dark and hard to see with ceiling-mounted shadowless light alone, areas such as behind/deep in the organs. We secured approximately 70cm (40cm+30cm) of surgical field through inverted L-shaped incision, but with the ceiling-mounted shadowless light only, the field was not clearly visible because the light was not bright enough to reach the dorsal surface of the liver, and also the surgical field was shadowed with my head.That's when we turned on OPELAEI and then the area between the dorsal surface of the liver and the inferior vena cava were brightly illuminated and became clearly visible. This is the first moment when I realized the effectiveness of OPELAEI. Clear visibility makes it easy to cut small blood vessels with little bleeding One of the advantages of the high-illuminant light from OPELAEI to the dorsal surface of the liver is that you can see the blood vessels being sutured to the intima adequately (Fig. 1). Another advantage is that the light is always focused to the surgical field where your eyes are focused, which assures you that the suturing is being performed at the best point.

Wearable Surgical Lighting System in Open Surgery Effectiveness of OFFI-KIH™ Vol.1 Gastroenterological Surgery Also, when dissecting the lymph node behind the portal vein, with OPELAEI, you can see small blood vessels and lymphatic vessels flowing into the lymph nodes (Fig. 2). When you can see the blood vessels clearly, you can do the dissection while cauterizing them. When bleeding occurs on the back of an organ, it takes a considerable amount of time to stop it. However it was not the case with OPELAEI and we were able to perform safe dissection with little bleeding. Another strong point...
