Doctor St. Laurent and his team take time listening to and explaining options to patients while encouraging pro-active and timely decision-making. His office and staff treat people with human dignity, not like numbers. I have consulted with many doctors before over the years and this was by far the nicest office with the best group you are going to find. A luxurious experience that truly helps people reach their goals, it does not get better than this.

Your Surgery Options

Many patients contact our Houston-area surgeon with questions about gastric bypass in particular, without realizing it is just one of many bariatric options available to treat obesity. When you meet with Dr. St. Laurent, he will help you determine the most appropriate way to address your condition. The options available to our patients include:

Gastric Bypass Surgery

Gastric bypass surgery involves dividing the stomach into two sections: a smaller upper section and a larger lower section. The small intestine is then connected to the upper portion of the stomach. After gastric bypass surgery, food will bypass the lower part of the stomach, allowing patients to feel full after consuming much less food. Although gastric bypass requires significant modifications to the stomach, it can help patients achieve a substantial amount of weight loss. Our surgeon will carefully assess your individual case to determine if gastric bypass or another type of bariatric surgery is right for you.

Read More about Gastric Bypass

Gastric Sleeve Surgery

During gastric sleeve surgery, also known as sleeve gastrectomy, Dr. St. Laurent removes a significant portion of stomach tissue, leaving a small section that resembles a thin, vertical “sleeve," which is then stapled shut. Having a smaller stomach limits the amount of food a patient can consume during a single meal. Over time, patients experience weight loss as their caloric intake becomes reduced. During a consultation, our surgeon can explain the full benefits of sleeve gastrectomy and discuss your needs and goals to determine if this bariatric treatment is right for you.

Loop Duodenal Switch

To perform a procedure known as duodenal switch, Dr. St. Laurent removes a large portion of the stomach and shortens the small intestine. Then, he will attach the intestine to the new, smaller stomach pouch. In order to reduce post-operative nutritional deficiencies, Dr. St. Laurent performs the SIPS (stomach intestinal pylorus-sparing surgery) technique. After a duodenal switch procedure, consumed food will bypass the upper portion of the small intestine, decreasing the amount of calories absorbed. This procedure can be revised or used to revise a previous type of surgery.

With the LAP-BAND system, Dr. St. Laurent places a LAP-BAND adjustable gastric band around the stomach, creating a smaller area for food. This decrease in size allows patients to feel as though they are full after eating only a small amount of food. After surgery, your caloric intake should drastically decrease, helping you to gradually lose weight. The LAP-BAND system offers several unique benefits. Most notably, it does not require significant modifications to your stomach or intestines. In addition, it can be easily reversed, should you decide in the future that the LAP-BAND system is not right for your lifestyle.

Revision Bariatric Surgery

In some cases, a patient will regain a significant amount of weight or experience complications following a bariatric procedure, necessitating a second surgery. Revision bariatric surgery may involve addressing an issue that arose from the initial procedure, or Dr. St. Laurent may convert one type of procedure into another. For example, we can use revision surgery to convert a gastric sleeve into a gastric bypass or duodenal switch, or convert LAP-BAND into a gastric bypass. Dr. St. Laurent will review your unique situation to determine the types of revision surgery that are right for you.

Bariatric Surgery Candidacy

Bariatric surgery is not recommended for all patients who are overweight. Instead, these procedures are designed for patients who have a body mass index (BMI) above 40, a BMI of 35 and an obesity-related condition, or those who are more than 100 pounds above their ideal body weight. Dr. St. Laurent will evaluate your candidacy for bariatric surgery during a personal consultation. In addition to meeting physical criteria, candidates must be ready to make significant lifestyle changes to help maintain a healthy weight and avoid future complications.

Read More about Candidacy

Bariatric Procedure Guide

Before surgery, we provide patients with a bariatric surgery guide to help ensure a safe and successful procedure. Since proper planning is vital to the ultimate success of your weight loss surgery, the guide will include instructions for both before and after your treatment. You can refer to the guide for pre- and post-operative meal plans, as well as recovery and eating guidelines for the coming years. It is imperative that patients follow all behavior modification instructions and exercise recommendations after surgery for continued success.

Read the Surgical Guide

Compare Surgery Options

We offer several weight loss surgeries, and each has its own set of benefits and important considerations. In order to help our patients make fully informed decisions about their care, we educate them about the differences between bariatric treatments. Each procedure involves a unique surgical technique and affects the body in different ways. In addition, the necessary lifestyle adjustments following surgery will be different depending on the procedure. During your consultation, Dr. St. Laurent will help you better understand the benefits and potential complications of each procedure.

Dr. Alain Elbaz's Story

A colleague of Dr. St. Laurent, Dr. Alain Elbaz had trouble losing weight through traditional means. Thanks to surgical treatment with Dr. St. Laurent, Dr. Elbaz reached his target weight, which allowed him to return to many of his favorite sports and athletic activities.

Nonsurgical Options Bariatric and Cosmetic Procedures

Weight loss can leave you with extra skin and stretch marks that won't go away even with a great diet and exercise routine. Our Houston office offers a few non-surgical procedures to help tone your figure after weight loss surgery. We also offer a bariatric surgery option that's nonsurgical for patients wary about surgery.

Gastric Balloon

You may not be ready to commit to the permanent effects of a surgical weight loss procedure like gastric bypass or sleeve gastrectomy. In that case, you can consider the gastric balloon. During a gastric balloon procedure, Dr. St. Laurent inserts a deflated balloon through your esophagus and into your stomach. Then, he inflates the balloon so it takes up a significant amount of space in your stomach. The treatment is safe, involves no incisions, and leads to healthy weight loss.

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!
