​The Benefits of Revision Surgery

Continued Weight Loss

If you have started to regain weight after your initial surgery, or you have reached a plateau in your weight loss, revision surgery can enable you to continue to lose weight at a healthy rate.

Address Complications

Previous surgeries can lead to mild complications, like acid reflux, or serious complications, like stomach obstruction. Also, the stomach pouch can expand over time after a gastric bypass or gastric sleeve. Revision surgery can address these issues to increase your long-term health and comfort.

A Fresh Start

Sometimes, patients see great weight loss results for a couple years after bariatric surgery, but then they start to regain weight. Maybe they've let their healthy habits slide, or maybe life changes have increased their stress levels. Whatever the reason, a revision surgery can provide a refreshed approach that supports patients in renewing their commitment to healthy living.

THERE IS HOPE  after failed results

A patient who has already undergone weight loss surgery may be interested in a conversion or revision surgery for a couple of reasons. The primary reasons include regaining weight after surgery and experiencing complications due to the original procedure. Dr. St. Laurent can convert a current bariatric procedure that is no longer working, helping patients throughout the greater Houston area reach their wellness goals.

What to Expect  During the Consultation Process

Dr. St. Laurent will find out as much as possible about your previous bariatric operation, as well as your weight loss experience, to determine what might have gone wrong. To choose the optimal method of revision, and to prepare you for surgery, you can expect...
Dr. St. Laurent has revised virtually every kind of bariatric surgery, using his experience to determine the best approach for each patient's unique case.

Physical Exam

Patients will undergo a medical examination to determine whether they are healthy enough to undergo bariatric revision surgery. We will ask about any medications you are taking and lifestyle factors such as your exercise and smoking habits. 

Anatomy Evaluation

Dr. St. Laurent will next evaluate the anatomy with an upper endoscopy or barium swallow. The goal is to assess your stomach lining and identify any potential issues or shortcomings of your previous procedure. 

Food Diary 

You may be required to keep a food diary for around two weeks and then bring it back for review. This will help Dr. St. Laurent determine whether changes in your diet might address your concerns.

Treatment Plan

Should Dr. St. Laurent decide that a second gastric procedure is the best recommendation, he will then give you pre-operative instructions to follow. These may include quitting smoking, modifying your diet, or eliminating certain medications. 

What kinds of revision bariatric surgeries are available?

What Can Be Revised?

If you are experiencing complications or unsatisfactory results from any kind of bariatric surgery, Dr. St. Laurent can evaluate your situation and determine if a second surgical procedure could address the problem. The most common types of revisions performed at our practice in Houston, TX, are...

​Gastric Sleeve Revisions

Over time, patients who undergo gastric sleeve surgery may experience two common issues: regular acid reflux and expansion of the stomach. Both of these issues can be addressed by converting the gastric sleeve to a gastric bypass or duodenal switch. 

Diagram of Gastric Bypass Revision Surgery

Gastric Bypass Revision

A common reason for revising a gastric bypass surgery is the expansion of the gastric pouch. Dr. St. Laurent can address this issue with a variety of laparoscopic methods, including a pouch reduction or bypassing more of the intestine to reduce the number of calories absorbed. A bypass procedure can also sometimes be revised to a duodenal switch.

Diagram of ​LAP-BAND Surgery

​LAP-BAND Revision

LAP-BANDs can tend to slip or loosen over time, leading to reduced weight loss. For qualifying patients, Dr. St. Laurent is able to either revise the band or remove it entirely and convert the weight loss surgery to a gastric bypass or gastric sleeve.


The Rate of Revision Comparing Surgeries


According to a study of nearly 41,000 weight loss surgery procedures in Surgery for Obesity and Related Diseases (SOARD), LAP-BAND accounted for 26% of revision or conversion surgeries. This was the most common revision or conversion surgery compared to gastric sleeve and gastric bypass. Gastric sleeve accounted for just under 10% of revisions or conversions. Gastric bypass accounted for just under 5% of revisions and conversions.

This 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!!!

Dr. 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!!!

Take a closer look at the different revision procedures...

LAP-BAND to Sleeve Revision

Dr. St. Laurent demonstrates how to perform a LAP-BAND to sleeve revision. After removing the gastric band, he then removes a substantial portion of the patient's stomach. This turns the stomach into a thin tube or sleeve. Because of the reduced stomach size, patients feel satisfied eating less food, and gradually experience less hunger overall.

Gastric Sleeve to Bypass Revision

In this revision, Dr. St. Laurent demonstrates the conversion of a gastric sleeve into a gastric bypass. The sleeve is first trimmed down to its original size and then stapled shut. To complete the gastric bypass conversion, the patient's small intestine is re-routed to reduce how many calories are absorbed during each meal.

Gastric Bypass Revision

In this revision, Dr. St. Laurent demonstrates the conversion of a gastric sleeve into a gastric bypass surgery. The sleeve is first trimmed down to its original size and then stapled shut. To complete the gastric bypass conversion, the patient's small intestine is re-routed to reduce how many calories are absorbed during the digestion of each meal.

VBG to Bypass Revision

Dr. St. Laurent demonstrates the conversion of a vertical banded gastroplasty (VBG) into gastric bypass surgery. The VBG procedure combined staples and a gastric band to create a pouch. By making small incisions in the abdomen, he can remove the portion of the stomach that was originally stapled off and reroute the small intestine. As a result, the patient can once again satisfy their hunger while consuming less food, and also absorb fewer calories during the digestion process.

Understanding the Risks 

While Northwest EndoSurgical takes advantage of innovative techniques and rigorous precautionary screening, all forms of surgery come with potential risks. The risks are slightly increased with revision procedures compared to initial bariatric surgery, and include:

  • Anesthesia-related risks
  • Nausea and vomiting
  • Acid reflux
  • Dilation of esophagus
  • Infection
  • Failure to lose weight

Dr. St. Laurent will go over all potential complications associated with the procedure, allowing you to weigh the benefits and risks. In some cases, Dr. St. Laurent may identify a non-surgical approach to your weight loss issues. Northwest EndoSurgical in Houston, TX, offers non-surgical weight loss programs, and we can work with patients who are looking for less invasive options. Our goal is to give you a comprehensive understanding of all of the factors involved in bariatric revision so you can make an informed decision about undergoing surgery

What can I expect after my operation?

Recovering from Bariatric Revision Surgery 

Inpatient Stay

Bariatric surgery revisions are inpatient procedures that are performed at our Houston area surgical center. Most patients will be admitted for one to three days for careful observation. In some cases, you may need to recover at the hospital for slightly longer than your initial weight loss surgery due to the difficult nature of these procedures.

Activity Levels

Most people can return home in only a few days, provided they can tolerate their postoperative diet and walk short distances. After revision surgery, you may need to have help getting around your home or performing household chores. You can gradually increase your activity to normal levels, which typically takes around six to eight weeks.

Full Recovery 

You can expect to return to most of your normal activities in four to five weeks after the operation, however, do not resume strenuous exercise until Dr. St. Laurent gives express approval. While all patients will recover on a slightly different timeline, make sure to attend all of your follow-up appointments so we can monitor your progress and identify any potential complications.


While many patients find success in weight loss after revision surgery, results will vary from patient to patient. Take advantage of the help offered by our staff dietitians and certified professional counselors to achieve maximum long-term success.
