  • 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.
    In addition to treating stomach cancer, this surgery may also be done to treat:
    • Ulcer disease
    • Bleeding
    • Inflammation
    • Benign tumors in the stomach
  • Possible Complications

    Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:
    • Damage to nearby organs
    • Leaking from the new connection between the stomach, intestine, and/or esophagus
    • Infection
    • Bleeding
    • Hernia formation at the incision site
    • Blood clots
    • Reaction to anesthesia
    Before your procedure, talk to your doctor about ways to manage factors that may increase your risk of complications, such as:
  • What to Expect

    Prior to Procedure
    Your doctor may do the following:
    • Physical exam
    • Blood tests
    • Fecal occult blood test (FOBT)—a test to check for blood in the stool
    • Endoscopy—a procedure that uses a scope with a camera on the end to examine the gastrointestinal system
    • Imaging studies to look at the esophagus, stomach, and intestine, including:
    Leading up to your procedure:
    • Talk to your doctor about your medications. You may be asked to stop taking some medications up to 1 week before the procedure.
    • Your doctor may recommend:
      • Eating a special diet
      • Taking antibiotics
      • Showering the night before your surgery using antibacterial soap
    • Arrange to have someone drive you to and from the hospital. Also, arrange for someone to help you at home.
    • Eat a light meal the night before the surgery. Do not eat or drink anything after midnight.
    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 your abdomen. Next, surgical instruments will be used to remove all or part of your stomach. If only part of your stomach is removed, it is called partial gastrectomy. With this type of surgery, the remaining part of your stomach will be connected to your esophagus and small intestine. If this is done for ulcer disease, the nerves that control acid production may also be cut. If all of your stomach is removed, it is called total gastrectomy. A new stomach will be made using your intestinal tissue. The end of your esophagus will be attached to your small intestine.
    If you have stomach cancer, the lymph nodes will be removed and examined as well. This is because cancer can spread through your 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.
    How Long Will It Take?
    1-3 hours or longer
    How Much Will It Hurt?
    Anesthesia will prevent pain during surgery. Pain and discomfort after the procedure can be managed with medications.
    Average Hospital Stay
    This surgery is done in a hospital setting. The usual length of stay is 6-12 days. Your doctor may choose to keep you longer if complications arise.
    Post-procedure Care
    At the Hospital
    Your doctor will give you guidelines on:
    • When and what you can eat
    • How you need to restrict your activity
    During the first few days after surgery, you may be restricted from eating. As your stomach stretches during recovery, you will be able to eat more at a time. If you had a total gastrectomy, you will need to eat smaller amounts of foods more often.
    After surgery, you may experience:
    • Frequent heartburn
    • Abdominal pain
    • Vitamin deficiencies
    To treat these symptoms, your doctor will:
    • Prescribe medications and vitamin supplements
    • Recommend medications to reduce stomach acid
    • Make changes in your diet
    Your bowels will work more slowly than usual. Chewing gum may help speed the process of your bowel function returning to normal.
    Preventing Infection
    During your stay, the hospital staff will take steps to reduce your chance of infection, such as:
    • Washing their hands
    • Wearing gloves or masks
    • Keeping your incisions covered
    There are also steps you can take to reduce your chance of infection, such as:
    • Washing your hands often and reminding visitors and healthcare providers to do the same
    • Reminding your healthcare providers to wear gloves or masks
    • Not allowing others to touch your incision
  • Call Your Doctor

    Contact your doctor if your recovery is not progressing as expected or you develop complications such as:
    • Signs of infection, including fever and chills
    • Diarrhea
    • Redness, swelling, increasing pain, excessive bleeding, or any discharge from the incision site
    • Persistent nausea and/or vomiting
    • Pain that you cannot control with the medications you have been given
    • Pain and/or swelling in your feet, calves, or legs
    • Pain, burning, urgency or frequency of urination, or persistent bleeding in the urine
    • Cough, shortness of breath, or chest pain
    • Swelling and/or pain in your legs, calves, or feet
    If you think you have an emergency, call for emergency medical services right away.
