Gastrointestinal Endoscopy

Business outline

An endoscope is a long, thin, flexible tube that has a camera at one end. Since it enables physicians to conduct tests and treatments with limited burdens on patients, it has been used widely in recent years. Gastrointestinal stents used with endoscopes can relieve a blockage or stricture caused by cancers, etc. and open up the passage to ease symptoms.

Endoscopic Submucosal Dissection (ESD)

Endoscopic Submucosal Dissection(ESD)is an advanced endoscopic procedure that removes early cancer from the gastrointestinal tract of a patient without removing the organ involved.
SB Knife™ is used to remove the lesions and for hemostasis.

SB-KAWASUMI will expand the product portfolio in the gastrointestinal endoscopy field to support patients in maintaining and improving their QOL.
