Gastric Sleeve Surgery

If you are living with obesity and can't seem to lose weight through diet and exercise alone, it may be time to consider bariatric surgery.

The gastric sleeve procedure is one of the most popular and most effective weight loss surgeries in modern bariatrics.

At Northwest EndoSurgical in Houston, Texas, we help patients lose weight with the gastric sleeve. Could it be right for you?

​The Benefits of Gastric Sleeve Surgery

Appetite Suppression

Gastric sleeve surgery involves reducing the stomach to less than half of its original size. A smaller stomach will result in you feeling full after eating less food, gradually producing healthy weight loss.

Minimal Scarring

Because our surgeon, Dr. Matthew St. Laurent, prefers to operate laparoscopically, the scarring from the surgery is minimal. The procedure only requires four or five small incisions in the abdomen that are less than half an inch long.

Improved Health

As you lose weight after your gastric sleeve surgery, obesity-related health conditions like Type 2 diabetes, obstructive sleep apnea, high cholesterol, high blood pressure, and more can improve.

Life-Changing Weight Loss

Within a year, many patients lose around 60-70 percent of their excess body weight, if not more. A healthier body and slimmer figure can help you take on the world with improved energy and confidence.

​How Does Gastric Sleeve Surgery Work? The Basics of Sleeve Gastrectomy

gastric sleeve

Gastric sleeve surgery or sleeve gastrectomy involves removing a significant amount of stomach tissue so the stomach is reduced in size to a small tube or sleeve. When the size of the stomach is reduced, patients require less food to feel full. Also, the reduction can trigger hormonal changes in the body which contribute to additional weight loss and improvement of weight-related health conditions.

Sleeve Gastrectomy Overview

This animation demonstrates how a sleeve gastrectomy is performed. Through small incisions in the abdomen, Dr. St. Laurent can remove a large portion of the stomach to form a much thinner vertical sleeve. This change in size reduces hunger and allows patients to feel fuller with less food.

Gastric Sleeve Surgery

Dr. St. Laurent performs a laparoscopic gastric sleeve surgery. Operating through small incisions in the abdomen, he removes a substantial portion of the stomach and staples the remainder together to form a long, thin tube or sleeve. Once confirming that the sleeve is sealed flush, the surgical instruments are removed and the incisions are sutured shut.

A New You Thanks to Gastric Sleeve Surgery

Dr. St. Laurent is now offering gastric sleeve surgery to help patients achieve their weight loss goals. Gastric sleeve surgery offers a number of benefits including relative simplicity and a quick recovery time when compared to other weight loss surgery options. The low-risk profile of the procedure also makes it an attractive option for many who are considering surgical weight loss options.

Gastric Sleeve Timeline What to Expect


During a consultation with Dr. St. Laurent, he will conduct an examination and recommend if he thinks bariatric surgery is right for you. He will cover all possible risks, costs, and necessary lifestyle changes. If you and the doctor decide to go through with a gastric sleeve, your procedure can be scheduled.


In the two-week period leading up to your surgery, Dr. St. Laurent's dietitians will recommend a dietary program for you, which will include low carb foods and protein shake supplements. He may also advise you to stop taking certain medications or forego smoking and alcohol.


When you come in for your weight loss surgery, you will be put under general anesthesia, so you will be totally unconscious during the procedure.


Dr. St. Laurent will make several small incisions around one-fourth to one-half of an inch in length in the abdomen. The surgeon will insert a laparoscope, or tiny camera, through one of these small incisions to broadcast images to a nearby video monitor. These images will guide Dr. St. Laurent in performing the operation.

Sleeve Gastrectomy

The surgeon will remove a sizable section of stomach tissue, reducing it to less than half of its normal size. The remaining stomach tissue will be a thin, vertical “sleeve,” which is then stapled shut. Dr. St. Laurent will then remove all of his surgical tools and sew the incisions closed.


To reduce the chances of serious complications after bariatric surgery, it is important to follow our recovery instructions very carefully. A patient manual will be provided. Your diet will be restricted for around one month after surgery. In the beginning, you may consume only liquids and will gradually add solid foods back into your diet over time. You will also need to minimize the amount of food you eat at one time. It’s important to drink plenty of fluids during the recovery period to avoid dehydration and help eliminate constipation.

Weight Loss

As you recover from bariatric surgery and eventually resume normal activity, you will find that you become full after eating less food. As your body absorbs fewer calories, you should experience dramatic weight loss in the first year. For the healthiest possible results, it is important to eat a nutritious diet and exercise regularly.

Real Patient Reviews "Gastric sleeve surgery... the best decision of my life!"

Posted 3.8.2017. Dr. St. Laurent gave me the tools I needed to change my life. He and his staff educated me about nutrition, my lifestyle change, and the procedure. He is very direct, honest, and  so supportive. He wants to make sure all questions and concerns  are addressed every time we meet and takes the time to do so.  I did a lot of research before choosing Dr. St. Laurent. After consulting with him I immediately knew he would be my surgeon. The few times I contacted his answering service after hours his response time was excellent. I had the Gastric Sleeve procedure on 9.8.2016. I have lost 92 pounds to date and still losing. For the first time in a long, long time I feel like I have control over my food consumption and addiction instead of it controlling me.  I can't begin to tell you how much this procedure and this journey has changed me as a person both mentally and physically. This was a major decision in my life and I'm so thankful I had Dr. St. Laurent as my doctor. I wish I could give him more than 5 stars!

I finally decided to have the gastric sleeve surgery done, and picking a doctor to do it was a big decision for me. I spent about 3 years researching gastric sleeve doctors and gastric sleeve patients stories.  I finally decided to book my appointment with Dr. St Laurent.... as soon as I met him, I knew I had to look no further.  He was a very nice guy, he explained everything about the procedure in detail and answered any questions / doubts that I had..... I knew I was in good hands!! I got my surgery on 2/2/17 and it was the best decision of my life!! I have had no complications with my surgery, everything has been great!!  I am excited for my new life/journey and I am so grateful to Dr. St. Laurent for giving that to me!! Not only is Dr. St. Laurent the best doctor, his staff is the best!! You guys are awesome!!!

Gastric Sleeve  or Gastric Bypass?

There are many different forms of weight loss surgery, but the most well-known are gastric sleeve surgery and gastric bypass surgery. Both are effective in helping patients lose weight, and both have similar recovery times and potential complications. The best surgical option for you is based on a variety of factors, including your weight and what underlying health conditions you have (for example, patients who suffer from acid reflux are better served by gastric bypass).

When you come in to our Houston, TX, area office for your bariatric consultation, Dr. St. Laurent will help you determine which weight loss procedure is right for you.
