Life-Changing Weight Loss Surgery  From One of the Houston Area's Most Experienced Bariatric Surgeons

Welcome to Northwest EndoSurgical. If you are considering weight loss treatment, we invite you to take the first step towards a healthier, more confident, and more active life.

At Northwest Endosurgical in Houston, Texas, bariatric surgeon Matthew St. Laurent provides modern, safe, and effective surgical solutions for patients struggling with obesity. Dr. St. Laurent has performed thousands of bariatric procedures over the course of more than two decades, including gastric bypass surgery, gastric sleeve surgery, duodenal switch surgery, bariatric revision surgery, gastric balloons, and Lap-Band® surgery.

Our patient care goes beyond surgery. Northwest Endosurgical is committed to helping our patients achieve long-term success through our weight loss treatments. Our staff includes bariatric-trained dietitians and certified professional counselors. Our bilingual team members allow us to serve both English and Spanish-speaking Texans. We guide our patients through every step of their weight loss journey before, during, and after surgery. We take great pride in seeing them achieve an improved quality of life.

Laparoscopic Surgery ​Reduced Scarring and Recovery Time

Dr. St. Laurent performs all of his weight loss surgeries laparoscopically as opposed to traditional open surgery.

During laparoscopic surgery, the surgeon makes a few small incisions on the abdomen through which he inserts a laparoscope (a surgical camera) and small, extremely articulate surgical tools. The view provided by the camera allows Dr. St. Laurent to perform the surgery with minimal incisions and alteration of tissue.

Bariatric procedures like gastric bypass, gastric sleeve, bariatric revisions, and Lap-Band placement can all be completed using laparoscopic techniques.

Laparoscopic surgery has many benefits:

  • Reduces the chances of surgical complications
  • Produces less noticeable scarring
  • Decreases the time needed to recover from weight loss surgery

Dr St. Laurent is a true scholar. During my initial appointment I felt as though I was taking a medical class in his office! He thoroughly explained every step of the procedure for me and helped me choose which gastric surgery was best for me. I could not ask for better care. He is truly a gifted surgeon who holds every one of his patients as his top priority. His office staff and nurses exceed expectations and are ready to help in any way. I recommend, without reservation, to anyone in need of gastric surgery to meet with Dr St Laurent.

Our Most Popular Procedures

Gastric Bypass

Gastric bypass surgery is a bariatric procedure in which the stomach is divided into two separate pouches: an upper pouch and a lower pouch. The small intestine is then connected to the upper pouch. Gastric bypass contributes to better appetite control, healthy weight loss over time, and an improvement in various obesity-related health conditions.

Learn More About Gastric Bypass

Gastric Sleeve

Gastric sleeve surgery, also known as sleeve gastrectomy, is a bariatric procedure that involves removing about 75-80 percent of the stomach. This removal results in a new stomach pouch that is about the size and shape of a small banana. Gastric sleeve surgery results in effective appetite suppression and can improve many health conditions associated with obesity.

Learn More About Gastric Sleeve


Also known as gastric banding, Lap-Band is a medical device that restricts the stomach, making it smaller. Treatment with the Lap-Band has the major advantage of being adjustable over time, allowing for steady and healthy weight loss. This bariatric surgery requires a shorter hospital stay and recovery period than other weight loss procedures. Lap-Band is also reversible.

Learn More About Lap-Band

Gastric Balloon

The gastric balloon procedure is a nonsurgical and completely reversible weight loss technique that is simple and effective. A safe silicone balloon is inserted into the stomach and filled with a saline solution. The inflated balloon takes up a significant amount of space in the stomach, making the patient feel full sooner. This restricts the number of calories consumed during the day.

Learn More about Gastric Balloon

Revision Weight Loss Surgery

If you've undergone weight loss surgery but are dissatisfied with the results or have experienced complications, Dr. St. Laurent can perform a revision of your prior bariatric procedure. Revision surgery may also be appropriate for patients who experienced weight loss after an initial bariatric procedure but the rate of weight loss has decreased or they have regained weight over time.

Dr. Laurent seemed genuinely interested in my health and spent a significant amount of time to explain my diagnosis thoroughly, along with providing several remediating options with varying associated costs and benefits (pros/cons). His recommended solutions were focused on mitigating my condition, rather than just treating my symptoms, unlike most GI doctors tend to do. I was very impressed by his wealth of knowledge and the fact that I never felt rushed during my Q&A. In addition, my appointment was on-time and the front office staff were very professional and amiable. I totally recommend Dr. St. Laurent for the most comprehensive, efficient, and positive patient experience!

Patient Wellness Before, During, and After Surgery

Northwest Endosurgical looks after each patient's health during all phases of bariatric treatment. Before, during, and after surgery, our team considers ways of minimizing risks to enhance the long-term benefits of weight loss. This dedication sets us apart from many other bariatric surgery centers serving the greater Houston area.

Post-Bariatric Body Contouring

Reducing excess body weight has a positive impact on wellness and helps address diabetes, hypertension, and other obesity-related health conditions. However, the dramatic loss of weight often results in wrinkles, loose skin, stretch marks, and other cosmetic imperfections. Many patients ask about treatments for these issues after they've lost their excess weight and achieved their health goals.

Thanks to the Icon™ Laser and the Evoke and Evolve systems, we can smooth away fine lines, stretch marks, and other common aesthetic flaws following a bariatric procedure. There is no surgery or downtime involved, and patients won't have to worry about scarring from these state-of-the-art laser and thermal technology treatments.

Post-bariatric body contouring may be just what you need to complete your life-changing transformation. During a consultation, we can discuss this option and determine if it's right for you.
