The AttachBend: a novel, lightweight, single-use bending attachment that adds a second bending function to a thin therapeutic endoscope (EG-840TP). a The AttachBend is attached to the endoscope. b Endoscopic bending at maximum upward angle of endoscope alone. c Endoscopic bending at maximum upward angle of endoscope and AttachBend. d The angle of the second bending can be adjusted by the operator’s hand.

Endoscopic submucosal dissection was performed for a 15-mm early gastric cancer located in the lesser curvature of the upper body.

a The muscle layer faced the endoscope, which made it difficult to continue efficient and safe dissection. b The AttachBend facilitated the approach to the submucosa parallel to the muscle layer and allowed effective countertraction by insertion of the endoscopic hood between the mucosa and muscle layer.

With the addition of the second bend, the knife could be applied to the edge of the submucosa, enabling efficient submucosal dissection.

En bloc resection was successfully achieved without adverse events.
