Experiencing weight regain or complications after your gastric sleeve? A revision surgery might be the solution.

Gastric sleeve revision is a secondary surgical procedure designed to correct or improve the results of an initial sleeve gastrectomy.

There are several revision options available, and the best choice depends on your specific condition and the issues you're experiencing.

If you're facing challenges after sleeve surgery, this guide will walk you through the available solutions—and our expert team is ready to help you take the next step.

What is a Gastric Sleeve Revision?

Gastric sleeve revision surgery is a follow-up procedure performed on patients who have previously undergone sleeve gastrectomy and either develop complications or fail to achieve enough weight loss.

The revision surgery for gastric sleeve aims to correct complications—such as acid reflux, gastric dilation, or insufficient weight loss—or enhance the long-term results of the initial surgery.

Depending on the patient’s condition, the revision may involve converting the sleeve to a different type of bariatric surgery or tightening the existing sleeve. Revision surgeries are typically more complex and carry higher risks than the initial bariatric procedure.

Why Would Someone Need a Gastric Sleeve Revision?

The most common reasons for revision of gastric sleeve are unsatisfactory weight loss, weight regain, or complications like acid reflux or stomach leakage.

A gastric sleeve is generally considered a failure if weight loss stops too early or the patient regains weight despite following a proper diet and exercise routine. This can happen if the stomach stretches or the original procedure wasn’t restrictive enough.

The sleeve revision helps restore the effectiveness of the surgery or improve the patient’s overall health and quality of life.

How Common is a Gastric Sleeve Revision?

Gastric sleeve revision isn’t extremely common, but it’s not rare either.

According to a 2020 study published in Obesity Surgery, around 5% to 10% of gastric sleeve patients may need a revision procedure within 5 to 7 years—mainly due to weight regain, sleeve stretching, or complications like acid reflux.

With techniques improving, sleeve revision is suspected to become more common in the coming years.

Gastric Sleeve Revision Requirements

To qualify for gastric sleeve revision, patients generally need to meet a few important criteria:

1. At least one year must have passed since the initial sleeve surgery.
2. The patient’s overall health and ability to withstand another surgery
3. Evidence of insufficient weight loss or significant weight regain.
4. Patients usually have a BMI of 35 or higher, or BMI above 30 with obesity-related conditions (for certain non-surgical revisions).
5. Complications such as severe acid reflux or GERD may justify a revision—often through conversion to a gastric bypass.

How is a Gastric Sleeve Revised in Turkey 2025?

A gastric sleeve is typically revised by converting the original procedure into another type of bariatric surgery

The most common gastric sleeve revision techniques include:

1.Gastric Sleeve Revision to Gastric Bypass:

Also called sleeve-to-bypass conversion, it is one of the most common techniques used when a gastric sleeve fails. According to gastric sleeve revision to bypass reviews it is the most effective revision technique for patients regain weight or need a significant change in their weights

Two main types of gastric bypass revisions are used in these cases:

1.Roux-en-Y Gastric Bypass (RYGB): The classic bypass technique with two anastomoses (connections).

2.One-Anastomosis Gastric Bypass (OAGB): A newer, simpler version with a single connection, offering similar weight loss outcomes and sometimes better results in certain

How Does Sleeve-to-Bypass Conversion Work?

Sleeve-to-bypass conversion involves creating a small pouch from the existing sleeve and rerouting the small intestine. This limits food intake (restriction) and reduces calorie absorption (malabsorption), making it highly effective for weight loss after a failed gastric sleeve.

2.Gastric Sleeve Revision to Duodenal Switch

The sleeve-to-duodenal switch (DS) conversion is a gastric sleeve revision technique that enhances weight loss by increasing the level of malabsorption.

How does sleeve-to-duodenal switch work?

Sleeve-to-duodenal switch works by rerouting the small intestine to bypass a large portion of it while keeping the original sleeve intact. This reduces calorie and nutrient absorption and is often used after a failed gastric sleeve due to weight regain, poor weight loss, or acid reflux. It’s especially effective for patients with a high BMI needing stronger metabolic support.

3.Endoscopic Sleeve Revision

Endoscopic sleeve revision is a minimally invasive, non-surgical procedure that restores the restrictive effect of a previous gastric sleeve.

How does endoscopic sleeve revision work?

The surgeon uses an endoscope inserted through the patient’s mouth under mild sedation to place internal sutures that tighten and reshape the stretched sleeve—without any external incisions. This method allows for faster recovery compared to traditional revision surgeries.

Can You Get a Gastric Sleeve as a Revision Surgery?

Yes, gastric sleeve isn’t only a primary weight loss procedure—it can also be performed as a revision surgery when other weight loss methods, such as the lap band, fail.

Lap band revision to gastric sleeve involves removing the gastric band and replacing it with a sleeve gastrectomy to enhance weight loss results and resolve complications related to the band.

In addition, sleeve-to-sleeve revision is another form of revision surgery, where a previously performed gastric sleeve is corrected through a second sleeve procedure, commonly referred to as a re-sleeve. This technique involves re-tightening or reshaping the existing sleeve to restore its original restrictive effect.

How Much Does a Gastric Sleeve Revision Cost?

The gastric sleeve revision cost in Turkey generally ranges from $5,000 to $15,000, depending on the type of revision procedure, the clinic, and the surgeon’s experience. Compared to other countries in Europe, Turkey offers much more affordable options for bariatric revision.

For example, the average cost of gastric sleeve revision is around $18,000 to $24,000 in Germany, $17,000 to $22,000 in France, and can go as high as $28,000 in the UK.

The price in Turkey varies based on the specific revision type, with the second sleeve costing between $5,500 and $8,000, which is similar to the cost of original gastric sleeve

If the revision involves converting the sleeve to a gastric bypass, the cost typically ranges from $7,500 to $11,000, while a conversion to a duodenal switch (DS) can reach $9,500 to $14,000.

For patients who qualify for endoscopic sleeve revision, the cost is generally lower, falling between $4,000 and $6,000.

Gastric Sleeve Revision Recovery Time

Patients expect a recovery time after a revised gastric sleeve that is generally comparable to the recovery of the primary sleeve, though it may take slightly longer in some cases

Most patients spend a few days in the hospital, followed by one to two weeks of limited physical activity.

Patients return to their normal activity within a few weeks, and the full recovery, including the ability to resume strenuous exercise, usually takes around six weeks or more.

However, the exact timeline depends on the patient’s overall health, how their body heals, and the specific type of revision performed.

Diet after gastric sleeve revision

The diet after gastric sleeve revision closely resembles the one followed after a primary sleeve surgery. Patients are advised to avoid carbonated beverages, straws, and chewing gum, as these can lead to increased air intake, causing bloating, discomfort, and potentially stretching the newly revised stomach.

What is the Gastric Sleeve Revision Success Rate?

Generally, Gastric sleeve revision has a success rate of 60% to 80%, depending on the reason for revision and the procedure type. Most patients experience significant weight loss and symptom relief.

Evidence also supports that re-operative bariatric procedures improve weight loss and help resolve comorbidities, with acceptable safety profiles compared to primary surgeries

Gastric sleeve revision studies support this evidence and compare the different revision techniques:

"In a 2023 study by Bonaldi et al., revisional sleeve gastrectomy showed an average excess weight loss (EWL) of 51 ± 38.6% at 5 years, with a low overall complication rate of 3.9%. The procedure proved effective in restoring weight loss and managing gastroesophageal reflux.” Bonaldi et al., Updates in Surgery, 2023

"A 2022 meta-analysis published in Obesity Surgery reviewed outcomes from different revisional procedures after failed sleeve gastrectomy, including Re-SG, RYGB, OAGB, DS, and endoscopic methods. It concluded that all procedures resulted in significant weight loss, with OAGB showing slightly superior outcomes in certain parameters.” Obesity Surgery Journal, 2022
