Antrectomy, Partial, or Subtotal Gastrectomy

An antrectomy, partial, or subtotal gastrectomy is the surgical removal of part of the stomach. It is performed to treat cancer of the stomach, ulcer disease, obstruction, or injury (trauma).


  • Allergies to food or medicine.

  • Medicines taken, including vitamins, herbs, eyedrops, over-the-counter medicines, and creams.

  • Use of steroids (by mouth or creams).

  • History of bleeding problems or blood clots.

  • Previous surgery.

  • Other health problems, including diabetes and kidney problems.

You will be monitored closely for complications during surgery and recovery. Many complications can be treated. Complications may include:

  • Bleeding.

  • Infection.

  • Reaction to anesthesia.

  • Damage to other organs or tissue.

  • Hernia.

  • Blood clot.


Before your procedure, you may have:

  • A physical exam, blood tests, stool test, X-rays, and other procedures.

  • Chemotherapy or radiation therapy.

  • Your caregiver review with you the procedure, the anesthesia being used, and what to expect after the procedure.

You may be asked to:

  • Stop taking certain medicines for several days prior to your procedure, such as blood thinners (including aspirin).

  • Take certain medicines, such as antibiotics or stool softeners.

  • Follow a special diet for several days prior to the procedure.

  • Avoid eating and drinking after midnight the night before the procedure. This will help you to avoid complications from the anesthesia.

  • Take an antibacterial shower the night before or the morning of the procedure.

Arrange for a ride home after surgery and to ask someone to help you with activities during recovery.


  • You will be given a medicine to make you sleep (general anesthesia) during the procedure.

  • The procedure takes a few to several hours to complete. You will not feel any pain.

  • Antrectomy, partial, or subtotal gastrectomy can be performed as an open procedure or a laparoscopic procedure.

  • During an open procedure, the surgeon will make a cut (incision) in the abdominal wall to access the stomach.

  • During a laparoscopic procedure, small incisions are made in the abdominal wall. Small, lighted tubes (laparoscopes) with instruments are inserted into the surgical site.

  • Sometimes, a combination procedure is performed using both of these techniques.

  • The surgeon will remove a part of the stomach and connect the remaining stomach to the small intestine. Depending on your condition, other parts (spleen, pancreas, lymph nodes) may be removed during surgery as well.


  • You will be monitored closely in a recovery room.

  • You will need to stay in the hospital for up to a week or longer, depending on your condition.

  • You will be given medicine for pain and nutrition through an intravenous (IV) access.

  • If you have a tube in the nose (nasogastric, NG tube) to remove fluids, it will be removed after 2 to 3 days.


  • Understand these instructions.

  • Will watch your condition.

  • Will get help right away if you are not doing well or get worse.
