Olympus Advancing Treatment with a large selection of ESD Knives on the Market
Treatment with gastrointestinal endoscopy has evolved rapidly, and Olympus has been there with innovative solutions every step of the way. From polypectomy to endoscopic mucosal resection (EMR) to today’s endoscopic submucosal dissection (ESD), treatment has become both more effective and less invasive.
With the remarkable ability to enable en bloc resection of lesions throughout the gastrointestinal tract, ESD represents a major milestone in this evolution. It offers a potential alternative for open surgery when treating larger lesions. It also has revolutionized the treatment for early gastric cancers, becoming the preferred modality worldwide.1
ESD allows for the removal of the entire tumor or lesion in one piece, leaving the native organ esophagus and stomach intact. It often enables a return to normal function, and in the case of achalasia, patients regain their ability to swallow. Patients typically experience shorter hospital stays, faster recoveries, reduced pain and less expense after ESD compared to open or laparoscopic surgical procedures.2,3,4,5
By eliminating the need for multiple resections, ESD is less likely to leave diseased tissue behind that would necessitate additional surgery, and en-bloc resections enable more accurate histopathologic evaluation and staging. Esophageal and gastric cancers and lesions have a significantly lower recurrence rate after ESD compared to other surgical options.
Japan has one of the highest incidence rates of gastric cancers, and in the late 1900s, its physicians began working diligently to find more effective treatments.i To aid in that effort, Olympus partnered with the National Cancer Center Hospital in Japan in the 1990s to collaborate with the country’s physicians in developing knives that helped resolve issues observed during EMR. The result was the introduction in 2002 of the world’s first knife capable of ESD, and a new treatment approach was born.
Following the introduction of the ITknife™ electosurgical knife, Olympus was instrumental in driving ESD adoption by collaborating with key physicians to analyze evidence-based data on the efficacy and safety of ESD.
After identifying areas for expansion, Olympus engineered a broader portfolio of options along with education and training for clinicians. The result is an expansive portfolio of ESD knives and peripherals and a procedure that has significantly advanced the possibilities for today’s minimally invasive surgeries.

Olympus has more than 100 years of experience and expertise in the manufacture of gastrointestinal endoscopy products, and we are known for our industry leadership in innovative technologies.
Starting with our work with physicians in Japan more than 20 years ago to develop knives that allowed the introduction of ESD, our teams continue to work with physicians around the world to offer best-in-class devices to meet every procedural application.
Olympus has a comprehensive portfolio of ESD knives on the market today, and we stay committed to advancing procedural possibilities. With the more recent additions of the
DualKnife J, TriangleTipKnife J and HookKnife J electrosurgical knives, Olympus now offers knives that enable dissection and lifting of the mucosa by injecting saline solution into the submucosal layer. This eliminates the need to change devices, potentially leading to shorter procedure times.
