Weight regain after gastric bypass surgery is a frequent occurrence, and statistics show that most patients gain back about 30% of the weight they lost, and almost 25% of them gain back all of it. This occurs for various reasons, such as an enlargement of the gastrojejunal outlet (the area where the gastric pouch is connected to the small intestine), stretching of the stomach pouch, or changes in eating habits or lifestyle.

Historically, patients had only surgical options available to address weight regain when traditional methods of weight management, such as diet and exercise, were not effective; these are invasive and associated with elevated risks and long recoveries.

Today, patients have a safer and more efficient option to address weight gain that does not involve surgery. TORe (Transoral Outlet Reduction) is a minimally invasive endoscopic gastric bypass revision procedure that can get your weight loss journey back on track.

At Reveal Weight Loss, patients have a safer and more efficient option to address weight gain after gastric bypass - the TORe procedure.

How Does TORe Gastric Bypass Revision Work?

A revision of gastric bypass works by reducing the size of the gastrojejunal outlet, which is the connection between the stomach pouch and the small intestine. By narrowing the outlet, TORe promotes better restriction and control of food intake, helping patients feel fuller for longer periods, and reducing the amount of food that can pass through the outlet at one time. This can help patients regain control over their eating habits and promote weight loss.

Who Is a Good Candidate For A Gastric Bypass Revision?

The endoscopic bypass revision procedure may be suitable for patients who have previously undergone gastric bypass surgery and have experienced weight gain or other complications related to the gastric outlet.

If you meet the following criteria you may be a good candidate for endoscopic bypass revision:

  • Previously undergone gastric bypass surgery
  • Experienced significant weight regain after their initial gastric bypass surgery or have not achieved sufficient weight loss despite their best efforts to follow a healthy lifestyle
  • Tried conservative measures, such as diet and exercise, to address weight regain after gastric bypass, without success
  • Good overall health and free from any significant medical conditions that could increase the risks associated with the procedure
  • Committed to making long-term lifestyle changes, including healthy eating habits, regular exercise, and ongoing follow-up with their healthcare provider to optimize the results of the procedure

What Are the Benefits?

  • The procedure is non-surgical and minimally invasive
  • There is no need for incisions
  • TORe is an outpatient procedure, so there is no hospital stay
  • Promotes further weight loss
  • Can improve metabolic conditions such as high blood pressure, type 2 diabetes, etc.
  • Very low-risk profile
  • Brief recovery time

What Can I Expect From The Procedure?

The gastric bypass revision procedure is performed endoscopically, which means that it is done through the mouth without any external incisions.

  1. The patient is typically placed under general anesthesia to ensure comfort and safety during the procedure. Once the patient is asleep, the doctor uses a flexible endoscope with a light and camera to visualize the gastrojejunal outlet, which is the connection between the stomach pouch and the small intestine.
  2. The doctor strategically places stitches to reduce the size of the gastrojejunal outlet and create a smaller opening that promotes better restriction and control.
  3. Once the procedure is completed, which normally takes about 30 to 45  minutes, the endoscope is removed, and the patient awakens from anesthesia.
  4. Patients are normally observed for one hour and then discharged to go home the same day as their procedure.

Recovery time is much shorter compared to traditional revisional surgeries, with most patients able to resume their normal activities within a few days.

What Is The Pre-Procedure Preparation For A Revision Of Gastric Bypass Surgery?

Typically, patients must adhere to a liquid diet for 24 hours before being put under anesthesia, having nothing to eat or drink after midnight the day before the procedure. This is done to ensure patient safety and the doctor will provide specific instructions for your circumstances before your procedure, so you will know exactly how to prepare for your gastric bypass revision.

What Is The Weight Loss Potential After Revision Of Gastric Bypass Surgery?

On average, patients experience a 10-15% reduction in total body weight after undergoing an endoscopic revision of gastric bypass surgery.

While this is not as significant an amount of weight loss as that achieved after the initial surgery, the revision procedure will assist patients by halting weight gain and promoting further weight loss. Each patient’s weight loss potential will vary due to factors such as their starting weight, overall health, and lifestyle changes, which include a healthy diet and daily physical activity.

What Are the Risks & Side Effects?

Typical symptoms after the procedure include abdominal cramping, nausea, bloating, and constipation. More severe risks including stricture of the gastric outlet, perforation, and fistula formation are extremely rare.

What Can I Expect During Recovery?

The endoscopic TORe procedure is performed on an outpatient basis, which means that patients are able to return home on the day of their procedure and do not require a hospital stay.

Because there are no incisions used during this revision to the gastric bypass, there are very few related risks. Some patients may experience mild throat or abdominal discomfort that may last a few days, but these can typically be managed with medications prescribed by the doctor.

Most patients experience a smooth recovery free from any serious complications and are back to their normal schedule in a day or two.

A special diet is required after the endoscopic TORe procedure, which involves a gradual progression from clear liquids to full liquids, pureed foods, soft foods, and eventually solid foods as tolerated. This gradual progression allows the patient’s digestive system to adjust to different textures and consistencies of foods after the surgery.

Frequently Asked Questions

Is The Endoscopic Tore Procedure A Major Surgery?

No, the endoscopic TORe procedure is a minimally invasive procedure that does not involve any external incisions. It is a significantly less invasive option compared to traditional revision surgeries for gastric bypass.

How Does The Endoscopic Gastric Bypass Revision Procedure Help Restart Weight Loss?

The endoscopic TORe procedure helps to restore the restrictive nature of the original gastric bypass surgery by further restricting the flow of food from the stomach pouch into the small intestine. This helps the patient feel full longer and leads to improved weight loss results.

What Will I Need To Do After Undergoing A Revision To Gastric Bypass Surgery To Maintain My Results?

To maintain your weight loss results after undergoing a TORe revision to gastric bypass surgery, it is important to follow a healthy lifestyle. Making lifestyle changes that promote weight loss would include consuming nutrient-dense foods, avoiding unhealthy food choices, getting an adequate amount of exercise, drinking enough water, getting an adequate amount of sleep, and managing stress levels. Our program at Reveal Weight Loss includes a year-long follow-up with a nutritionist/dietician.
