Case Video

At first, it was difficult to identify the bleeding point due to continuous bleeding after the procedure. However, after turning on the RDI™ technology function, the bleeding site could be clearly identified. By distinguishing between the bleeding source and its surroundings and by quickly stopping bleeding, additional time and effort could be saved.

Overall Comment

It was difficult to find the bleeding point particularly in heavy bleeding. However, when observed with RDI technology, the color of blood was observed as light reddish brown, making it easier to find the bleeding point than it was before. With this point of view, RDI technology enhances the efficiency of the procedure and patient safety at the same time it increases the rate of hemostasis of possible bleeding during and after resection.
