ESD is a complex procedue. High quality instruments are critical for a successful endoscopic treatment. Recently, hybrid knives are actively developed by a various vendors.
Recently, I sometimes use H-type ESD knife from Finemedix company (located in Daegu). It has a I-tip (similar to Dual knife from Olympus) and O-tip (similar to IT-2 knife from Olympus) in a single catheter.
