Weight loss surgeries like gastric bypass and gastric sleeve have the potential to produce significant results in less than a year.

"I am thrilled to be a success story."
It's very rare that you find a really, really good doctor. Especially one who is seriously interested in your well being. It's not a gimmick. It's what he does. From his office staff to his team of assistants, they are all the best. I highly recommend Dr. St. Laurent and his team. I had surgery in November and to date I have lost almost 45 pounds. I am thrilled to be a success story in his book. I am a new person!! Thank you, Northwest EndoSurgical Team!!! I will continue with my journey.
View On GoogleThis was my initial consultation. Everyone is very professional, helpful, and caring. Dr. St. Laurent and his staff were amazing . He took the time to explain all the procedures and the risks, as well going over my options for the best possible outcome. His whole approach to obesity is recognizing it as a disease that requires long-term treatment and commitment. I found that encouraging. There is no judgement. I never felt uncomfortable, exactly the opposite. I was able to be honest about myself and why I want to start this journey during any of the consultation. His insurance specialist is a great help providing actual fees and costs covered and not covered. Five stars!!!

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.
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.
Lap-Band
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.
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.
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. St. Laurent is one of the best."
The most beautiful and professional people I have ever met. The team is courteous and organized. Your health concerns are thoroughly addressed. The procedure to improve your health is thoroughly explained, and they don't waste your time.
View On GoogleDr. St. Laurent is one of the best doctors I ever had. During the consultation, he spent almost an hour trying to find the best option based on 2 previous surgeries. He’s patient and kind and really cares about his patients. I was super scared about one of the pre-op tests, and he came to make me feel comfortable. After surgery, he explained everything and there were no complications. I’m 2 days post-op and a little sore but feeling better each day. I am grateful for Dr. St. Laurent and his entire team!!!
View On GoogleLaparoscopic 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

Patient Wellness Before, During, and After Surgery

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.
