Gastric Bypass Revision

What’s Gastric Bypass Revision?

A gastric bypass revision, also known as bariatric revision, or Transoral Outlet Reduction (TORe), is a non-surgical outpatient procedure performed by a gastroenterologist or a bariatric surgeon to suture a previous gastric bypass. Gastric Bypass is an extremely effective bariatric surgery that results in significant weight loss as evidenced by the overwhelming number of gastric bypass success stories. However, many patients experience weight regain years after their initial weight loss. The purpose of performing a gastric bypass revision is to address weight regain due to stretching of the gastric pouch and the gastric outlet following the initial surgery. 

Who is Gastric Bypass Revision for?

Revision is an option for most patients who have previously undergone gastric bypass surgery but are now experiencing weight gain. The procedure is non-surgical and minimally invasive, so as long as patients are in good overall health, there are very few risks to a gastric bypass revision. Success after the revision is largely dependent on keeping up with healthy changes. The best candidates are usually those who are willing to commit to lifestyle changes that support their weight loss goals, such as healthier eating habits and regular exercise.  

How Does Gastric Bypass Revision Work?

Most patients are relieved to hear that hospitalization is not on the list of gastric bypass revision requirements. Rather, it’s an outpatient endoscopic procedure that is performed under sedation. Because it’s not a surgery, there are no incisions or scars. Instead, the endoscopist introduces an endoscope, a narrow tube with a camera and light on its tip, through the mouth, and advances it to the gastric pouch. The endoscope is equipped with a suturing device, allowing the doctor to place sutures at the gastro-jejunal anastomosis and in the pouch, to restore both the outlet and the pouch to their original sizes.

Meet Kim

One of our favorite gastric bypass revision success stories. Kim had laparoscopic open gastric bypass surgery in 1999 and lost 220 pounds. But, after twenty-one years of life’s ups and downs—including giving birth to twins—she had regained a little under half of her weight. Two months after her gastric bypass revision, Kim had already lost 20 pounds.

“I never thought a revision would be possible for me. Then, I read about a new procedure. Dr. Charbel would be able to go down my throat and revise from inside my stomach. The support is phenomenal, and no question is insignificant! The whole team, from Dr. Charbel, his staff, and a nutritionist, are incredibly responsive. I am so excited, knowing that I am getting healthier!”
— Kim Cole

Gastric Bypass Revision: FAQs

At The Silhouette Clinic, we understand that taking control of your weight and overall health can be a daunting experience. We also understand that you’ll probably have several questions, from understanding the gastric bypass revision cost to anticipating the results you can expect. We’re committed to supporting you every step of the way to ensure you have all the information you need to make the best decision. 

Here is a comprehensive list of our most frequently asked questions to help with your research. 

How common is a gastric bypass revision?

The need for gastric bypass revision depends on several factors, including the original surgeon’s experience and the individual patient’s needs and goals. However, many patients eventually experience a dilation of their gastric pouch which results in a dilation of the outlet and therefore a loss of the restriction.

Is gastric bypass revision safe?

Gastric bypass revision is very safe because it’s an endoscopy and not a surgical procedure, Like any medical procedure, gastric bypass revision carries some risks. However, most can be minimized by ensuring you’re in the best possible physical health in the lead-up to your procedure.

Choosing the best endoscopist is also essential. Dr. Charbel is a career specialist in gastroenterology, hepatology, and nutrition. He is a highly skilled advanced endoscopist and he is board-certified in gastroenterology and obesity medicine.  Dr. Charbel is an active member of the American College of Gastroenterology, the American Gastroenterological Association, the American Society of Gastrointestinal Endoscopy, and the Obesity Medicine Association.

What are the benefits of gastric bypass revision?

In addition to weight loss patients, patients who are motivated to adopt and maintain healthier lifestyles are rewarded with additional health benefits like improvement in blood sugar levels, blood pressure, and mood.

Do I have to be under a specific BMI to have the procedure?

There are no strict BMI gastric bypass revision requirements. Ideal candidates are patients who are experiencing weight gain years after having undergone a gastric bypass surgery, who were found to have a dilated gastric outlet on endoscopy, who are committed to making significant lifestyle changes, and who do not wish to undergo high-risk revisional surgery.

How do I prepare for gastric bypass revision?

Your weight loss package with The Silhouette Clinic includes pre-procedure support to help you prepare. You may need to stop taking certain medications, adjust your diet, or undergo preoperative testing to ensure that you are ready. To achieve optimum results and the best possible outcome, we ask patients to follow our instructions closely in the lead-up to the procedure.

How long do gastric bypass revisions take?

The process from beginning to end takes just a few hours. You’ll need to arrive an hour before your scheduled procedure time, and the actual endoscopy process takes around 30 minutes. You’ll be monitored for a couple of hours afterward to ensure we can provide you with the necessary IV fluids and pain or nausea medications before you are discharged.

What is the recovery time?

You’ll need 2–3 days after your gastric bypass revision to rest, after which you can resume your regular routine and return to work.

Are there any side effects to be aware of?

Most patients experience some mild nausea and abdominal pain or discomfort immediately after the procedure and in the following few days. These symptoms can usually be controlled by medication and typically last less than a week.

Do I need a follow-up procedure to remove the sutures?

No. The sutures are very small and remain within the wall of the stomach without you being able to feel them. Initially, the sutures hold the outlet at its new size. However, once healed, the outlet holds its new size without the support of the sutures, and there’s no need to undergo an additional procedure to remove them.

What is the gastric bypass revision success rate

Like most procedures, the gastric bypass revision success rate depends on patient selection. If the gastric outlet is found to be significantly dilated on endoscopy, the gastric bypass revision is expected to have a very high success rate and the weight loss results are excellent. However, if the gastric outlet dilation is noted to be mild, then the weight loss results may be suboptimal, and other options such as weight loss medications need to be considered either as an alternative to, or an adjunct to gastric bypass revision. 

How much weight will I lose?

As with any weight loss program, results can take time — and will vary depending on each individual patient’s commitment to maintaining a healthy lifestyle and following dietary recommendations. It is essential to note that all of the weight loss services we offer at The Silhouette Clinic are part of a more comprehensive weight loss program that includes ongoing support and lifestyle changes. However, most people lose 10-15% of their total body weight within around 12 months of the procedure.

Does insurance cover gastric bypass revision?

While there are several significant health benefits to our weight loss procedures beyond weight loss, endoscopic gastric bypass revision is not covered by insurance. However, we do offer a range of financing options through Care Credit.

What is the average weight loss after gastric bypass revision?

Weight loss after gastric bypass revision varies depending on several factors such as the amount of weight gained back after the initial surgery, the size of the pouch, and most importantly the size of the gastric outlet. The average weight loss after gastric bypass revision is between 10% and 15% of total body weight. 

Do you perform gastric bypass pouch tightening?

An endoscopy is performed and the sizes of the gastric pouch and the gastric outlet are assessed. In the gastric bypass revision, the outlet is sutured and tightened then, if the pouch itself is large enough, gastric bypass pouch tightening is performed. 


While the weight loss procedures we offer provide major health benefits beyond weight loss, they are not covered by insurance. However, we do offer financing:
