  6. Follow steps 1– 3 in Subheading 3.2 to expose the distal
    esophagus.

  7. Carefully lift the stomach to expose its dorsal side.

  8. Ligate the distal esophagus with a 5-0 silk ligature and cut at
    the esophagogastric junction.

  9. Ligate the duodenum at the pyloric ring and remove the whole
    stomach.

  10. After confirmation of hemostasis, close the abdominal wall and
    the skin separately with 6-0 Vicryl.


4 Notes



  1. Use an operating microscope (25×).

  2. Maintain the body temperature intraoperatively by using a
    heating pad.

  3. Before closing abdomen, fill the peritoneum with saline solu-
    tion to replace intraoperative volume loss [ 10 ].

  4. Administer analgesic to alleviate pain on postoperative day 1
    (buprenorphine 0.05 mg/kg, SC).

  5. Deprive mice of food for 24–48 h postoperatively, but allow
    free access to drinking water.

  6. Assess the general health condition of the mouse on a daily
    basis after surgery. If the mouse becomes hyposthenic, eutha-
    nize the mouse.
