​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 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 revision surgery for a couple of reasons. The primary reason is regaining weight post-operation, and the second is a complication due to the original procedure. Dr. St. Laurent can convert a current procedure that is no longer working or causing issues so that patients can reach their 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. 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 determines 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 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.


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 LAP-BAND®, he then excises a substantial portion of the stomach to form a thin tube or sleeve. Because of the reduced size, patients are satisfied with less food and gradually experience less hunger overall.

Gastric Sleeve to Bypass Revision

Dr. St. Laurent performs a gastric sleeve to bypass revision. The sleeve is first trimmed down to its original size and stapled shut. During the gastric bypass, the intestines are re-routed to reduce how much is absorbed from each meal.

Gastric Bypass Revision

Dr. St. Laurent performs a gastric bypass revision for a previously failed procedure. The stomach is trimmed down to reduce room for food. The re-routing of the intestine is then revised to ensure that the connections are sealed flush.

VBG to Bypass Revision

Dr. St. Laurent demonstrates VBG to bypass revision surgery. Making small incisions in the abdomen, he can remove the portion of the stomach that was originally stapled off and re-route the intestine. As a result, the patient once again can satisfy hunger with less food and absorb fewer calories.

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 look at 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 inpatient procedures 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 longterm success.
