Comparing Reduction With ESD- Versus APC-TORe

The E-TORe utilizes ESD in addition to APC prior to endoscopic suturing. In this approach, a standardized solution of normal saline or hetastarch mixed with methylene blue and epinephrine is injected into the gastric rim of the GJA outlet. The mucosa is then carefully incised to expose the underlying muscular layer for a width of approximately 1cm around the GJA circumference. Following ESD, APC is then applied to the inner and outer mucosal margins of the ESD tract. Finally, endoscopic sutures are then placed in purse string fashion and cinched closed around a 6mm TTS balloon.

The c-TORe will be completed utilizing APC prior to endoscopic suturing. In this approach, the gastric rim of the anastomosis is circumferentially ablated using APC (forced APC, flow of 0.8 L/min and power of 30-70 watts) extending an average of 1-2 cm from the outlet. Following ablation, endoscopic sutures are placed in a purse string fashion within the ablated area and the outlet cinched closed over a 6mm through-the scope (TTS) balloon.
