Feasibility of Endoscopic Pylorotomy in the Treatment of Refractory Gastroparesis, Pilot Study.

The procedure is endoscopic pylorotomy. The standard procedure consists in the realization of a longitudinal incision of 2 cm at the anterior surface of the gastric antrum at 5 cm from the pylorus after a submucosal injection of a solution containing 85% saline 10% glycerol and 5% fructose. This longitudinal incision serve as an input for producing a submucosal tunnel dissected fibers gastric submucosa step. The internal circular of the pyloric muscle is then severed fiber after fiber over its entire length and its entire thickness. Once the pyloric section completed, the tunnel inlet will be closed by means of hemostatic clips.
