Endoscopic submucosal dissection of a large cecal polyp using a scissor-type knife: implications for training in ESD

Determining the Safety and Effectiveness of Electrocautery Enhanced Scissors for Peroral Endoscopic Myotomy (with Video)

“…Notably, gastroenterology fellows participated in the myotomy in each procedure. As mentioned previously, given the stability and ease of use of the device, it allows for safe handling by both expert level clinicians and fellowship trainees, 28,29 and similar outcomes were observed in our POEM cohort. While using the EES device, fellows can grasp the inner circular muscle prior to the incision.…”

“…28 Thus, given the stability and ease of use of the device, it allows for safe handling by both expert level clinicians and fellowship trainees. 28,29 Although previous studies have investigated the role of EES device in ESD, no original studies have evaluated the efficacy and safety of the device in POEM. In addition to the improved accuracy and precision for dissection, as well as the improved safety in training fellows, the EES device also provides hemostasis without the need for device exchanges.…”

“…Furthermore, Yamashina et al demonstrated in a single-center phase II trial that the use of the scissor-type knife significantly improved the trainees’ self-completion rates for colorectal ESD, without an increase in procedure time or adverse events [ 28 ]. Thus, given the stability and ease of use of the device, it allows for safe handling by both expert level clinicians and fellowship trainees [ 28 , 29 ]. Although previous studies have investigated the role of EES device in ESD, no original studies have evaluated the efficacy and safety of the device in POEM.…”

Polypectomy of a giant sessile polyp in the hepatic flexure using scissor-type forceps and a gravity traction method to create a pseudo-peduncle

“…However, we now have fast, easy, and safe endoscopic submucosal dissection (ESD) devices [3], that can help in performing en bloc resection. This case report, similarly to previous ones [4], demonstrates that the scissorstyle knife can safely speed en bloc re-section in a western setting. Further studies are needed to assess the efficacy and safety of this device when used in the resection of protruding polyps by nonexpert ESD endoscopists.…”

A novel approach for endoscopic submucosal dissection: scissors versus electricity

“…SB Knives (Olympus America, Center Valley, Pa, USA) and the Clutch Cutter (Fujifilm, Tokyo, Japan) have recently become available in the United States 7, 8, 9, 10, 11. Although these devices have 2 branches and resemble scissors in appearance, their branches are not sharp and cannot mechanically cut tissues.…”
