Figure 4 Endoscopic incision and cutting procedure. A: Food residues retained in the duodenal bulb through the pylorus are observed; B: Retained food residues were expelled into the gastric cavity; C: The web is projected distally, so that the end appears like a blind pouch, and the aperture is observed at 12 o'clock; D: After attaching a transparent cap to the tip of the endoscope, a small radial incision was carefully made into the web using a IT2-knife; E: In the center, toward the duodenal wall, a long radial incision was made; F: The web was cut circumferentially along the duodenal wall.
