Revision surgery is a second bariatric operation after a first one that caused complications, stopped working, or never worked well enough. At Valentmedica, an all-inclusive package in Istanbul costs £4,200–£5,600, with a bariatric surgeon experienced in revisions, three to four nights in a JCI-accredited hospital and a year of dietitian support.

Revision surgery is any second bariatric operation performed after a first one. It may convert one procedure to another, repair a complication, or remove a device that is causing problems.
Roughly one in five bariatric patients eventually needs some form of revision. That is not a sign the first operation failed in any dramatic sense — anatomy changes, pouches stretch, bands erode, and reflux develops. What matters is identifying why the first operation stopped working, because a revision that does not address the actual cause will not work either.
Revisions are technically harder than first-time surgery. Scar tissue from the original operation obscures the normal planes, the tissue is less forgiving, and the complication rate is roughly double. They should only be done by surgeons who perform them regularly.
| You had | Problem | Usual revision |
|---|---|---|
| Gastric sleeve | Severe acid reflux | Conversion to Roux-en-Y bypass |
| Gastric sleeve | Weight regain, dilated sleeve | Re-sleeve or conversion to bypass |
| Gastric band | Slippage, erosion, poor loss | Band removal, then sleeve or bypass |
| Mini bypass | Bile reflux | Conversion to Roux-en-Y |
| Roux-en-Y bypass | Weight regain, dilated pouch | Pouch revision or limb lengthening |
| Any procedure | Excessive weight loss, malnutrition | Reversal or limb shortening |
A Valentmedica all-inclusive revision package in Istanbul costs £4,200–£5,600 depending on complexity. Revisions cost more than first-time surgery everywhere, because they take longer and carry more risk.
| Revision | Price (GBP) | Hospital nights | Nights in Turkey |
|---|---|---|---|
| Sleeve to Roux-en-Y bypass | £4,200–£5,400 | 3–4 | 8 |
| Band removal only | £2,400–£3,200 | 2 | 5 |
| Band removal plus sleeve | £4,400–£5,600 | 3–4 | 8 |
| Re-sleeve (dilated sleeve) | £3,800–£4,800 | 3 | 7 |
| Mini bypass to Roux-en-Y | £4,200–£5,400 | 3–4 | 8 |
| Pouch revision after bypass | £4,000–£5,200 | 3 | 8 |
A revision cannot be quoted responsibly without knowing exactly what was done the first time. Valentmedica asks for your operation note, discharge summary and any recent endoscopy or imaging before giving a price. If you cannot obtain them, we will still assess you — but expect the plan to be confirmed only after the diagnostic endoscopy in Istanbul.
Elsewhere you usually pay for the operation alone. A Valentmedica package also includes your hospital stay, hotel, transfers and a personal coordinator.

Indicative figures, not a quote. Bars show the usual range in each market; overseas figures are typically surgeon and facility only. Flights are an estimate for a return economy fare. Your price is confirmed in writing after a clinician has reviewed your case.
The best candidates have a clearly identified anatomical or clinical reason for revision, have addressed any behavioural factors, and understand that a second operation carries higher risk than the first.
Our BMI and eligibility calculator is a starting point, but revision assessment is genuinely individual. A bariatric surgeon reviews your records free of charge and will tell you plainly if surgery is not the answer.
Eight nights in Istanbul — one more than a first-time operation, because revisions carry a higher complication rate and deserve a longer watch.
You send your original operation note, discharge summary, recent bloods and any imaging. A bariatric surgeon reviews them, and you receive a written assessment setting out what is likely to be needed and what it will cost.
Your driver meets you at Istanbul airport and takes you to the hotel.
Blood tests, ECG, chest X-ray, endoscopy and usually a contrast swallow study to map your current anatomy. Consultations with your surgeon, the anaesthetist, the dietitian and, where relevant, a psychologist.
Your surgeon confirms the exact revision based on what the investigations showed. If the findings change the plan, the price is confirmed in writing before anything proceeds. You are admitted in the evening.
Two to four hours depending on complexity and how much scar tissue is present. You wake in your room and will be walking the same evening.
A swallow test confirms the new joins are sealed before you begin sips of water.
You move to the hotel with daily coordinator contact and the hospital fifteen minutes away.
Bloods repeated and your surgeon confirms you are fit to fly.
Fly home with your discharge summary, medication, supplements and a written diet plan.
Dietitian appointments at 2 weeks, 1, 3, 6 and 12 months, with your surgeon available throughout.
The hospital and hotel you will be using, and the specifics you can check before you pay a deposit.
The facility is named to you in writing, with its licence and accreditation numbers, so you can verify it rather than take our word for it. If you would like to see the building, ask: we can usually arrange a visit before you decide.
Keyhole surgery under general anaesthetic wherever possible, taking two to four hours. The defining difference from first-time surgery is scar tissue.
Where a band has eroded or there is significant inflammation, surgeons often stage the revision: remove the band first, allow three to six months of healing, then perform the sleeve or bypass as a second operation. It means two trips, and it is considerably safer.
Recovery is slower than after a first operation — expect three to five weeks before a desk job and six to eight weeks before heavy activity. The diet stages are the same but often more cautious.
Revisions carry roughly double the complication rate of first-time bariatric surgery. In experienced hands they are safe operations, but the margin is narrower and surgeon experience matters more than anywhere else in this field.
Valentmedica refers revisions only to surgeons who perform them regularly, in JCI-accredited private hospitals with intensive care on site. You are given your surgeon's name, registration number and an indication of their revision volume before you pay anything.
Hiatus hernia repair is very often part of a revision, particularly where reflux is the reason for it. Body contouring remains a separate trip.
Because revisions are longer and higher-risk than first-time operations, surgeons are more conservative about adding anything. A procedure is combined only where leaving it undone would undermine the revision itself.
Gather your original operation records, follow the liver-shrinking diet, address the behavioural side honestly, and plan for a longer recovery than last time.
Where the revision addresses a clear anatomical problem, results are good: reflux resolves, bands stop causing trouble, and further weight loss of 40–60% of remaining excess weight is typical.
The outcome depends almost entirely on why the revision was done. Converting a sleeve to a bypass for severe reflux is highly effective at fixing reflux, and that is usually the patient's main complaint. Revising for weight regain is less predictable: where imaging shows a genuinely dilated pouch the result can be excellent, but where the anatomy is intact and the problem is eating behaviour, a second operation rarely delivers what the patient hoped.
The patients who do best after revision are the ones who treated it as a reset rather than a rescue — who used the pre-operative assessment to address eating patterns honestly, and who stayed engaged with follow-up afterwards. Valentmedica includes twelve months of structured dietitian support and a psychological assessment as standard for revisions, and you can see outcomes at 12 and 24 months in our weight-loss before and after gallery.
At Valentmedica, £4,200–£5,600 all-inclusive for most conversions, and £2,400–£3,200 for a band removal alone. Revisions cost more than first-time surgery everywhere, because they take longer and carry more risk. Flights are not included.
Revisions have roughly double the leak rate of first-time surgery, and previously operated tissue heals less predictably. The extra night keeps you in Istanbul through more of the window in which a problem would appear.
Possibly, but not necessarily. If endoscopy and imaging show a genuinely dilated sleeve, a re-sleeve or conversion to a bypass can help considerably. If your anatomy is intact and regain came from grazing or liquid calories, a second operation is unlikely to fix it — and dietitian and psychological support should come first.
Conversion to a Roux-en-Y gastric bypass is the standard and highly effective answer, because bile and acid no longer reach the oesophagus. A hiatus hernia repair is often done at the same time, since an untreated hernia is frequently the underlying cause.
Sometimes, if the band is in good position with no erosion or significant inflammation. Where there is erosion or inflammation, surgeons prefer to remove the band first and perform the sleeve three to six months later. It means two trips and it is considerably safer.
Typically 40–60% of your remaining excess weight — meaningfully less than a first operation achieves. Expect improvement rather than a repeat of your original result.
They make a real difference. The operation you need depends on what your anatomy looks like now, and knowing exactly what was done first is the best starting point. If you cannot obtain them, we will still assess you, but the final plan will be confirmed only after the diagnostic endoscopy in Istanbul.
Yes. The leak rate is roughly double, bleeding is more likely, and there is a small chance of needing to convert to open surgery because of scar tissue. This is why revision volume matters when choosing a surgeon.
At least 12 to 18 months unless there is a complication. Weight loss continues for well over a year after a first operation, and revising too early means operating before you know what the first procedure actually achieved.
Yes. A Roux-en-Y can be reversed or the limb lengths adjusted, and a mini bypass can be taken down relatively readily. Malnutrition after a malabsorptive procedure is a legitimate reason for revision and should not be left untreated.
For revisions, Valentmedica includes one as standard. This is not a hurdle — it is because the behavioural picture is a major determinant of whether a second operation will help, and skipping it is how patients end up having a third.
Then they will tell you, and we would rather that happened at the assessment stage than afterwards. Where surgery is not indicated, Valentmedica can still offer dietitian and behavioural support, and you are not charged for an operation that does not take place.
