  6. The surgeon uses the stapler to divide the upper part of the small intestine into a tube with two ends.
  7. Once done, one of the small intestines is brought up to the stomach pouch. A small connection (called anastomosis) is made between them. The other end of the tube is then connected to another part of the small intestine.
  8. Once done, the surgeon will perform the endoscopy to test for any leak (if present).
