In surgical procedures, although resection and hemostasis maneuvers have become more efficient through the use of dedicated devices, no dedicated device for the dissecting (detaching) maneuver exists at present. The Cavitron ultrasonic surgical aspirator (CUSA: Integra lifesciences Corporation, NJ, USA) is a device originally used mainly for hepatic parenchyma resection in the gastrointestinal surgical field. Tissue is selectively fragmented by an ultrasonically vibrating chip at the tip of the device. Furthermore, physiologic saline is ejected from the tip and aspirated with the fragmented tissue by the device. By reducing the amplitude of the CUSA to 10-20 %, we have been using the device not only for hepatic parenchyma resection but also for dissection in gastrointestinal surgical procedures in general. Here, we explain the details of the techniques that we routinely use, such as dissection of vessels and lymph nodes in radi...
