Vertical banded gastroplasty is surgery to treat
obesity. It changes the stomach to cause weight loss. A small pouch is made at the top of your stomach. Weight loss occurs because this smaller stomach limits the amount of food you can eat.
This surgery treats morbid obesity (also called clinically-severe obesity). Doctors use a calculation called body mass index, or BMI, to determine overweight or
obesity. A normal BMI is 18.5-25. If your BMI is 40 or more, you are at least 100 pounds over normal weight for your height.
This surgery may be for people with the following factors:
- BMI greater than 40, or 100 pounds overweight
-
BMI 35-39.9 and a life-threatening condition, such as heart disease or
diabetes
- BMI 35-39.9 and severe physical limitations that affect employment, mobility, and family life
Each bariatric surgery program has specific requirements. Your program will likely include the following:
- Thorough physical exam and review of medical history
- Attempts to lose weight (about 10%) through medically approved dietary means
- Ongoing consultations with a registered dietitian
- Mental health evaluation and counseling
In the days leading up to your procedure:
- Review your regular medications, herbs, or dietary supplements with your surgeon. You may need to temporarily discontinue some
of these products.
- Do not start any new medications, herbs, or supplements without talking to your doctor.
- Arrange for a ride to and from the hospital.
- Arrange for help at home as you recover.
- You may be given antibiotics.
- You may be given laxatives and/or an enema to clear your intestines.
- The night before, eat a light meal and do not eat or drink anything after midnight unless told otherwise by your doctor.
- Shower or bathe the morning of your surgery.
- Bring all your medications with you to the hospital.
To prepare you for surgery, a nurse will place an intravenous (IV) line in your arm. You may receive fluids and medications through this line during the procedure. The doctor will place a breathing tube through your mouth and into your throat. This will help you breathe during surgery. You will also have a catheter placed in your bladder to drain urine.
There are two methods for vertical banded gastroplasty:
The open method begins with an 8-10 inch incision to open the abdomen.
The laparoscopic method begins with several small incisions in the abdomen. Gas is pumped in to inflate your abdomen. This makes it easier for the surgeon to see. Your surgeon passes a laparoscope and surgical tools through these incisions. A laparoscope is a thin, lighted instrument with a tiny camera that projects images of your abdominal cavity on a monitor. Your surgeon performs the operation while viewing the surgical area on this monitor.
Both surgical methods proceed as follows: Your surgeon uses surgical staples to divide your stomach into two unequal portions. The upper portion is a small pouch. It empties through a tiny opening into the lower portion. Next, your surgeon wraps a band of polypropylene mesh around the tiny opening to prevent it from stretching. This band can be adjusted after surgery.
The small pouch can hold only ½ to 1 cup of soft, moist, and well-chewed food. A normal stomach can hold 4-6 cups.
Your surgeon will close the incisions with staples or stitches.
The breathing tube will be removed and you will be taken to the recovery area. You’ll be given pain medication.
- Anesthesia prevents pain during surgery.
- Patients may have pain and/or soreness at the incision sites. Your doctor can give you pain medication to relieve the discomfort.
Risks associated with vertical banded gastroplasty:
- Vomiting, due to eating too much or narrowing of the passage between the pouch and the rest of the stomach
- Breakdown of the staples, allowing stomach juices to leak into the abdomen—A pureed diet and eating slowly reduce this risk.
- Slipping or wearing away of the band
- Enlargement of the pouch
- Reflux esophagitis
- Vitamin deficiencies—You will take a multivitamin daily for the rest of your life.
- Wound infection
- Bleeding
- Abdominal hernia, occurs in 10%-20% of patients and requires surgical correction—The risk is lower with laparoscopic surgery.
-
Gallstones, which can occur with rapid weight loss—Your surgeon may remove your gallbladder during surgery, or instruct you to take bile salt supplements after surgery.
- Heart and lung problems
-
Blood clots in the vein (phlebitis) or traveling to the lungs (embolism)—Blood thinners before and after surgery, and elastic surgical stockings during recovery reduce this risk.
- Complications of general anesthesia
- Death, occurs in less than 1% of patients
2-5 days (Patients usually go home earlier after a laparoscopic procedure than an open procedure.)
While you are recovering at the hospital, you may receive the following care:
- Pain medication will be given as needed.
-
If you have
sleep apnea, you’ll be placed on a breathing monitor.
-
Your diet:
- Day of surgery—You won't eat or drink anything.
-
Day after surgery—You’ll likely have an upper GI
x-ray
to check for leaks from the stomach pouch. You’ll drink a special liquid while x-rays are taken.
- If this x-ray is normal, you’ll be given 30 milliliters (mL) of liquids every 20 minutes.
- If leaks are found, you’ll receive nutrition through an IV until the leaks are fixed.
- Second day after surgery—You’ll have1-2 tablespoons of pureed food or 1-2 ounces of liquids every 20 minutes.
-
You may be asked to do the following:
- Use a spirometer to take deep breaths every hour to prevent breathing problems.
- Wear elastic surgical stockings to promote blood flow in your legs.
- Get up and walk in the hall daily.
You may be out of work for 2-6 weeks after surgery (less time with laparoscopic, but more time following an open procedure). Do not drive or lift anything heavy for at least two weeks. You’ll need to practice lifelong healthful eating and exercising habits. You should walk as soon as possible, with a goal of exercising daily. You may have emotional ups and downs after this surgery. You will meet regularly with your healthcare team for monitoring and support.
Your new stomach is the size of a small egg. It is slow to empty, causing you to feel full quickly. You need to eat very small amounts and eat very slowly. You’ll begin with 4-6 small meals per day. A meal is two ounces of food. For the first 4-6 weeks after surgery, all food must be pureed. Once you move to solid foods, food must be well-chewed.
When making food choices, ensure that you are getting adequate protein. Eating too much or too quickly can cause vomiting or intense pain under your breastbone. Most people quickly learn how much food they can eat. Unlike gastric bypass, vertical banded gastroplasty does not cause symptoms—such as nausea and
diarrhea—if sweet or fatty foods are eaten. In fact, some people gain back weight because they continue to consume soda, ice cream, or other high-calorie foods. To promote ongoing weight loss, avoid high-calorie foods.
The success of vertical banded gastroplasty depends on your commitment. If lifestyle changes are made and maintained, the benefits of bariatric surgery include:
- Weight reduction—In the first year, most people lose 50%-60% of their excess weight; however, some people regain weight in the next 3-5 years. The long-term results with vertical banded gastroplasty may be poorer than with other procedures.
-
Improvement in many obesity-related conditions, such as glucose intolerance, diabetes,
sleep apnea,
high blood pressure, and
high cholesterol
- Improved mobility and stamina
- Enhanced mood, self-esteem, and quality of life
After you leave the hospital, call your doctor if any of the following occurs: - Signs of infection, including fever and chills
- Redness, swelling, increasing pain, excessive bleeding, or discharge from the incision site
- Cough, shortness of breath, chest pain, or severe nausea or vomiting
- Worsening abdominal pain
- Blood in the urine or stool
- Pain, burning, urgency, or frequency of urination
- Pain and/or swelling in your feet, calves, or legs
- Any other worrisome symptoms
