The Dilumen platform is very useful in ESD where access to the lesion is very difficult (for example in patients with loops (generally in sigma -alpha loop-), in lesions located behind folds and in those where there is fibrosis. It incorporates a movable distal balloon and a proximal balloon located in the device’s overtube, as well as an accessory channel through which a rotary clamp can be inserted in the three dimensions of the space to make traction from the created mucosa flap.
