Snare-assisted flexible endoscope in trans-gastric endoscopic gallbladder-preserving surgery: A pilot animal study

Figure 1 Snare-assisted flexible endoscope in transgastric endoscopic gallbladder-preserving surgery. A: The anterior wall of the gastric antrum was incised; B: The snare was placed on the transparent cap (red arrow); C: The endoscope was inserted into the abdominal cavity. The gallbladder was located; D: The transparent cap clung to the gallbladder wall, and the gallbladder wall was sucked in it. The snare was released, and the gallbladder wall was ligated; E: This ligation state was maintained; F: The gallbladder wall was incised with the assistance of the snare; G: With the navigation of the snare, the endoscopist quickly found the gallbladder and gallbladder incision again (blue arrow); H: With the help of the snare, clips were used to close the gallbladder wall incision; I: The snare was loosened (yellow array); J: The gallbladder wall returned to normal.
