Reasons for Procedure
Gastrectomy is most often done to treat stomach cancer. It is currently the only way to cure stomach cancer. The use of chemotherapy and radiation may help improve survival. Even if the cancer is too advanced to be cured, gastrectomy can help to prevent bleeding, obstruction, and pain.

General anesthesia will be used. It will block any pain and keep you asleep through the surgery.
Description of the Procedure
An incision will be made in the abdomen. Surgical instruments will be used to remove all or part of the stomach. If only part of the stomach is removed, it is called partial gastrectomy. With this type of surgery, the remaining part of the stomach will be connected to the esophagus and small intestine. If this is done for ulcer disease, the nerves that control acid production may also be cut. If all of the stomach is removed, it is called total gastrectomy. A new stomach will be made using the intestinal tissue. The end of the esophagus will be attached to the small intestine.
If you have stomach cancer, the lymph nodes will be removed and examined as well. This is because cancer can spread through the lymphatic system.
After the surgery is complete, the muscles and skin of the abdomen will be closed with stitches or staples. A dressing will be applied.
