Bariatric Surgery

What is laparoscopic bariatric surgery?

Bariatric surgery is an approach to weight loss for people who are having severe problems with their weight. It typically involves removing or closing off a portion of your stomach to reduce its capacity and interfere with your digestion.

By being unable to overeat and following a healthy diet and exercise program, even morbidly obese patients for whom nothing else has worked can achieve their ideal weight.

Laparoscopic bariatric surgery is a minimally invasive approach that avoids the need for Dr. Nazarian to make large incisions in your body. Instead, he makes several small incisions, into which he passes a flexible instrument called a laparoscope.

The laparoscope has a camera that sends back clear images of the surgery site. Dr. Nazarian uses these images to guide other laparoscopic instruments and complete your surgery with minimal blood loss, pain, or scarring.

Do I qualify for laparoscopic bariatric surgery?

As a general guide, you need to have a BMI (body mass index) of 40 or over to qualify for bariatric surgery, or a BMI of 35-40 and serious underlying health issues.

BMI is a way of assessing how healthy your weight correlates to your height and current weight. It's not a precise method of determining healthy weight, but it does give an accurate indication for most people.

You also need to show your commitment to the process and have a good understanding of what laparoscopic bariatric surgery involves.

What types of laparoscopic bariatric surgery might I need?

There are several types of laparoscopic bariatric surgery that Dr. Nazarian could perform, including:

Sleeve gastrectomy

Sleeve gastrectomy is similar to gastric bypass in some respects, in that Dr. Nazarian removes a large part of your stomach. However, rather than rerouting the small intestine, he creates a banana sized pouch (the sleeve) that restricts food intake.

The Gastric Sleeve is done by using surgical stapler to remove
the large reservoir component of the stomach. This operation
helps patients achieve a very satisfactory level of weight
loss, while being simpler than the Gastric Bypass and easier to
maintain weight loss than the Gastric Band. The Gastric Sleeve has
been in use in US since about 2004 and surgeons are very encouraged with the result achieved. This procedure is very protective in prevention and treatment of metabolic disease such as diabetes, and quite effective weight
loss sustained over many years.

Roux-en-Y gastric bypass

Gastric bypass surgery involves removing most of your stomach and reattaching your small intestine, so food bypasses part of the digestive process.

Gastric Bypass is still the most effective weight loss
procedure that exist. Gastric Bypass is not for everyone
however for this procedure it is safe and done
laparoscopically, surgery done by separating small portion of the stomach out of the large stomach. Then the intestine brought up and connected to this new stomach. In this case not only the stomach is reduced to a very small portion which controls the food intake, also food bypassed main stomach and part of the intestine which causes less absorption . This procedure offers dual effect of restriction and melabsorption, stay in hospital is minimal 2-4 days most.

What is gastric bypass surgery?

Gastric bypass surgery is a weight-loss surgical technique that “bypasses” a portion of your stomach and small intestine so you eat less and fewer calories are absorbed. The surgery is considered a combination of restrictive and malabsorptive surgeries since it involves elements of both.

How is the gastric bypass surgical procedure performed?

Gastric bypass is performed using a laparoscopic technique, a minimally-invasive approach that uses small incisions so recovery is faster and risks are decreased. During the surgery, your stomach will be divided into two sections – an upper pouch, which will be about the size of a large walnut and able to contain only about an ounce of food, and a larger lower portion which will be “bypassed.” The smaller pouch will be disconnected from the upper part of the small intestine and reconnected at a lower area. 

By bypassing the upper portion of the small intestine where much of the digestive activity occurs, your body will not absorb as many calories. Once the procedure is completed, you will need to remain in the hospital for about two to four days during the initial stages of healing and recovery.

Am I a good candidate for gastric bypass?

Generally, the gastric bypass surgical procedure can be a good option for patients who:

  • Are in good general health
  • Have a body-mass index of 40 or greater
  • Have a body-mass index between 35 and 40 in addition to a medical condition related to obesity, like type II diabetes or hypertension (high blood pressure)

Before gastric bypass surgery or any type of weight-loss surgery, you will have a thorough medical exam and consultation with Dr. Nazarian to determine if weight-loss surgery is right for your health, your lifestyle, and your goals.


The Lap-Band is a device that closes off part of your stomach with a band rather than removing it permanently. It's reversible, so when you reach your target weight, Dr. Nazarian can remove it.

Gastric balloon

The gastric balloon is also reversible. With this procedure, Dr. Nazarian inserts a medical balloon into your stomach and inflates it to take up most of the space, leaving a small area for food.

Dr. Nazarian can also perform revisional weight loss surgery for patients who have undergone bariatric surgery elsewhere but have experienced difficulties or complications.

If you're obese and unable to find an effective weight loss solution, laparoscopic bariatric surgery may be a good choice for you. Learn more by calling the office of Jamshid Nazarian, MD, FACS, today or request an appointment online.

Revision for Previous Bariatric Surgeries

Many procedures for weight loss has been done in the past which were not perfected. Those procedures done because the new procedures of today were not available at that time.

Many times patient has insisted upon one procedure over another which has not been the right decision and many times the surgeon has not offered the right procedure to his or her patient.

Many patients has taken the surgical procedure as the main player in their weight loss and has not done their share of staying on the right path of diet and exercise or they have lost follow up altogether.

Combination of all these factors can make one procedure unsuccessful for the patient necessitating changing of that procedure to another surgery or correction of existing condition. This is the meaning of revisional surgery.

Revisional Surgery is more challenging than initial surgery and requires more expertise on part of the surgeon. During this procedure the area that has been manipulated in the past will be dissected off from surrounding tissue, cleared and prepared for correction or taking down of existing condition and then placing a new procedure.

We require to have the old operating note, evaluating your anatomy, assuring that you comply with post weight loss protocol and provide support of nutritionist and advise you prior offering you another surgery. Most of the time this correcting procedure improves your obesity and co-morbidities providing you be a team player and helping us to help you.

We must have the following information before an appointment is made:

• Copy of prior operative note and discharge summary. We are also interested
in other medical data from the time around surgery.

• Upper GI X-ray -- we need to see if the anatomy is surgically correctable.

• Established contact of the patient with a primary physician - because of the increased complexity of a revision procedure a patient should have a professional medical advocate.
