My gastric sleeve failed. What are my revision options in Mexico?

Your options depend on why the sleeve failed, not on how much you weigh. Severe reflux usually means converting to a bypass. Weight that came back usually means SADI-S or a bypass. Re-sleeving is the weakest of those options. And nothing gets decided before endoscopy and imaging.

I'm Dr. David Lomelí Reyes, a bariatric and metabolic surgeon in Cancún, Mexico (CMCOEM CB240071 · Cédula CE 14247260 · ASMBS · IFSO (MX102) · ACS). Most of the people who write me about a failed sleeve open with an apology. They tell me what they ate, or didn't eat, or how they fell off the plan. Then somewhere in the third message they mention the heartburn that wakes them up at 3 a.m., or that they never got past a certain number even in the first year. That second part is the medical information. The apology isn't.

01 · Failed, or normal?

Did my gastric sleeve actually fail, or is this normal?

A sleeve is generally considered to have fallen short when you lost less than 50% of your excess weight at appropriate follow-up, or when the weight came back after you got there. That's the threshold in the revision literature, and it's the one I work with (Brethauer et al., ASMBS Revision Task Force, SOARD 2014).

But the number on your scale is only one of the ways a sleeve fails. Severe reflux that showed up after surgery counts. Grade C or D esophagitis counts. Type 2 diabetes that never went into remission counts. A complication from the first operation counts. Any one of those changes the conversation as much as the weight does.

Here's the part almost nobody tells you: the scary regain statistics you've been reading are not one statistic. In a large prospective US cohort of bypass patients, the share of people counted as having "regained" five years past their lowest weight was 43.6%, 50.2%, or 67.3% — same patients, same follow-up, three different thresholds (King et al., JAMA 2018). That study was in gastric bypass patients, not sleeve patients, so don't apply the exact figures to yourself. Apply the lesson: whoever quoted you a regain percentage picked a definition, and they probably didn't tell you which one.

So before I call anything a failure, I want to know when your lowest weight was, how far you've come back from it, and whether anything else broke. Not how disciplined you've been.

02 · Why sleeves fail

Why do gastric sleeves fail?

Four things account for most of what I see.

The sleeve stretched. The gastric tube can dilate over time, and a dilated tube is a recognized reason people come back for a second operation — it's the explicit indication in a good chunk of the re-sleeve literature. On an upper-GI series and on endoscopy it's usually obvious.

The first sleeve wasn't tight enough to begin with. Not every operation called a sleeve gastrectomy removes the same amount of stomach. When I scope someone who never lost well in year one — not regained, never lost — a generous remnant is one of the things I'm looking for.

A hiatal hernia was there and nobody found it. This one bothers me the most, because it's the most fixable and the most missed. In a series of 434 bariatric patients where the operating room was used as the reference standard, preoperative endoscopy picked up hiatal hernias with 75.68% sensitivity — meaning 9 of the 37 hernias that were actually there, close to one in four, only turned up once the surgeon was inside (Chan et al., JGH Open 2020). If yours was one of those, your reflux was never a discipline problem.

The disease didn't stop being a disease. Obesity relapses. The operation changes your anatomy and your hunger signaling; it doesn't repeal the condition. I'll say the same thing to you I say in my office: regain is a clinical finding to work up, not a character flaw to confess.

There's a fifth possibility that isn't really a failure at all, and it's why I ask when your surgery was. Most of the fast loss happens in the first six months and weight tends to settle around month 18. Judging a sleeve at month seven is judging it halfway through.

03 · Re-sleeve

Can a stretched gastric sleeve be tightened?

Yes, and I want to be careful with this answer, because "tightening" is the phrase people search and re-sleeve gastrectomy is the operation they've usually found.

Re-sleeve is real surgery, and by the numbers it's the gentlest of the revisions. A pooled analysis of ten studies and 300 patients put the leak rate at 2.0% and overall complications at 7.6%, with mean excess weight loss around 61% over follow-up of one to three years (SOARD 2020). Compared with the bigger conversions, it's shorter, simpler, and less morbid.

Now the catch, and it's a big one. In a network meta-analysis of revisions after failed restrictive surgery, re-sleeve was the revision most burdened by weight recidivism — patients converted to a single-anastomosis duodeno-ileal bypass instead had dramatically lower odds of regaining (odds ratio 0.07 versus re-sleeve), and both duodenal switch and Roux-en-Y bypass produced more total weight loss at one and three years — with the duodenal-switch margin much larger than the bypass one (International Journal of Surgery 2022). The same analysis found the reverse trade on safety: duodenal switch and RYGB carried roughly two to three times the odds of late major morbidity compared with re-sleeve.

That is the honest shape of the decision. The safer operation is the one most likely to leave you back here in four years. The more effective operation asks more of your body and more of your follow-up. Anyone who presents re-sleeve as the obvious easy fix has left out half the data.

I do perform re-sleeve. And I'll say it plainly: of the revision options, it's the one I recommend least — for exactly the reasons above.

And re-sleeve does nothing for reflux. If reflux is your problem, re-sleeving a refluxing stomach is the wrong direction — that's a conversion to bypass conversation, not a tightening conversation.

04 · Endoscopic sleeve

Does an endoscopic sleeve work as a revision?

This is where I have to correct a lot of what's circulating, and I'd rather annoy you than mislead you.

Endoscopic sleeve gastroplasty — ESG, the "endo-sleeve" — is a genuine procedure with genuine evidence. In a randomized trial across nine US centers, ESG produced mean excess weight loss of 49.2% at 52 weeks versus 3.2% for lifestyle modification alone, with serious adverse events in 2% of patients (Abu Dayyeh et al., The Lancet 2022). Solid work.

But look at what that trial tested: ESG as a first procedure, against lifestyle changes alone, in people with class 1 and class 2 obesity — not ESG as a revision of anyone's prior sleeve. ESG is a primary procedure. It is not a study-supported way to revise a surgical sleeve gastrectomy, and if a clinic in Mexico or anywhere else is selling it to you as one, ask them for the trial.

The broader picture on endoscopic revision points the same way. In a systematic review of revisional treatments for weight regain after gastric bypass — the setting where endoscopic revision has the most published experience — the authors concluded that endoscopic procedures had short follow-up and produced weight loss that was "modest and temporary," while surgical revision techniques were the durable ones (Obesity Reviews 2023).

So: an endoscopy is central to your evaluation. I want one before I say anything about an operation. As the treatment itself, for a failed surgical sleeve, it is a relative contraindication due to stenosis risk and other complications — it would never be recommended as a revision procedure.

For the record: we do perform endoscopic sleeve gastroplasty with my endoscopy team — as a first procedure, and only at the patient's request, because it is not superior to the laparoscopic sleeve.

05 · Plication

Is gastric plication an option after a sleeve?

Almost certainly not, and the reason is anatomical rather than philosophical.

Gastric plication — laparoscopic greater curvature plication — works by folding the greater curvature of the stomach inward and stitching it down. Your sleeve gastrectomy already removed the greater curvature. There is no longer a fold to make.

The same anatomy closes another door people ask about: a fundoplication — the classic anti-reflux operation — can no longer be done after a sleeve, because it wraps the fundus around the esophagus and the fundus was removed with your sleeve. It's part of why post-sleeve reflux points toward conversion to bypass instead.

Even as a first operation it's the weaker choice. Across 18 studies and 1,329 patients, sleeve gastrectomy beat plication on excess weight loss at 1, 3, 6, 12 and 18 months (Obesity Surgery 2021), and a separate review of 3,103 plication patients found most studies stopped following people at 12 months (Obesity Surgery 2021). ASMBS has had a policy statement on the procedure since 2011 — you can pull it up yourself.

If you're searching "gastric plication Mexico" because someone quoted you one as a revision, that's a reason to slow down and ask what they think your current anatomy looks like.

06 · Which revision

Which revision would I actually recommend for you?

It depends on which of the two problems you have. I'll give you my actual reasoning.

The map, not the verdict: which branch you're on is confirmed by endoscopy and imaging, not by this diagram.

If the problem is reflux. Conversion to a bypass is the clearest answer I have in all of revision surgery. The sleeve can worsen reflux; the bypass generally improves it, and with severe reflux — grade C/D esophagitis, or Barrett's — the indication is clear. In a long-term randomized comparison, Barrett's esophagus was found in 30.8% of sleeve patients versus 13.6% of bypass patients at roughly 7.5 years, and the authors' recommendation was routine endoscopic surveillance for bariatric patients generally (ANZ Journal of Surgery 2025). That study was small — 48 patients, and the gap didn't reach statistical significance — so treat it as a direction, not a verdict. But it points the same way everything else does.

If the problem is weight that came back. Conversion to SADI-S or a bypass. Six cohort studies comparing duodenal-switch-type conversions against RYGB after a failed sleeve found the duodenal-switch group achieved about 10% more total weight loss, with no significant difference in length of stay, adverse events, or comorbidity improvement — though the duodenal-switch patients started heavier, which flatters the comparison (SOARD 2019). More weight loss, more malabsorption, more supplementation. That trade is the whole conversation, and it's the one I want to have with you before anything is scheduled, not after.

The step-by-step of each operation — what happens in the OR, hospital nights, recovery timeline — is on my revisional bariatric surgery page.

Dr. David Lomelí Reyes operating in a hospital operating room in Cancún — Dr. Lomelí in the operating room. Reoperative surgery runs harder than a first operation — which is why the evaluation comes before anything is scheduled.

Two things I want to be blunt about. Your sleeve is not reversible. Part of your stomach was permanently removed; "fixing" a sleeve means converting it or adjusting it, never returning to the starting point. And revision is riskier than your first operation — the ASMBS Revision Task Force review found complication rates generally higher after reoperative surgery than after primary surgery (SOARD 2014). Adhesions from the first operation, altered anatomy, a harder dissection. That's not a reason to refuse revision. It's a reason to want an evaluation instead of a package, and to be pickier about the second surgeon than you were about the first.

07 · Cost drivers

What does gastric sleeve revision cost in Mexico?

I don't publish prices, and for revision I'd refuse to even more firmly than for a primary operation. Here's what actually drives yours.

Which operation you end up needing. A re-sleeve and a conversion to SADI-S are not the same event in the operating room. They differ in duration, in complexity, in what the hospital bills.
How difficult your abdomen is. Adhesions from your first surgery are the single biggest unknown, and nobody — me included — can price them from a photo and a message. The revision literature is unanimous that reoperative cases run harder than primary ones.
Whether a hiatal hernia repair comes along for the ride. Given that close to one in four of those only appear intraoperatively, this is a real branch, not a hypothetical.
Which hospital, and how many nights. Revision patients stay longer and get watched more closely than primary patients. That's a medical decision that has a cost consequence, not the other way around.
What workup you still need. If you already have a recent endoscopy and imaging, that's work you don't repeat.
The follow-up program. After a malabsorptive conversion this is not optional and it is not a courtesy — see the section below.

Notice that four of those six are unknown until someone has looked at your anatomy. Which is exactly why a number handed to you before an evaluation isn't a price — it's a guess with a deposit attached. Send me your case and I'll tell you what I think you need first; the cost of your case gets discussed once there's a case to cost. If you want to see how I approach quoting in general, I wrote that out for primary sleeve patients.

08 · Candidacy

Am I a candidate for revision — or not?

You're likely a candidate if you lost less than 50% of your excess weight or the weight came back, if severe reflux or grade C/D esophagitis showed up after your sleeve, if you're carrying a complication from the first operation, or if diabetes never remitted. And — this is a requirement, not a footnote — if you understand that a second operation carries more risk than the first and you still want to go forward (SOARD 2014).

You may not be a candidate, or not yet, if:

You're seven or eight months out and still on the descending part of the curve.
Your regain is real but the workup finds no anatomic explanation and you haven't yet had a serious run at nutrition and medical management. Reoperating on a normal-looking anatomy rarely produces what people hope for.
You can't commit to lifelong supplementation and lab work. After a malabsorptive conversion that's not a lifestyle preference, it's the safety condition of the operation.
You want a price before an evaluation. I'm not going to give you one, and I'd be wary of whoever will.

09 · US follow-up

What happens with follow-up once you fly home to the US?

This is the question I'd want answered first if I were you, because the first time around it's usually the part that quietly wasn't there.

The logistics of my own follow-up — direct WhatsApp, the check-in schedule, how long you stay in Cancún before I clear you to fly — are covered on my US-patient page and in the piece on how long to stay. What's different about revision is the clinical load you're taking home.

Hospital Galenia, private surgical hospital in Cancún where Dr. Lomelí operates — Hospital Galenia in Cancún — one of the private surgical hospitals where Dr. Lomelí operates. Revision patients stay longer and get watched more closely before being cleared to fly.

Your labs stop being routine. A 2025 meta-analysis of 14 studies and 1,049 patients revised after sleeve gastrectomy found deficiencies in vitamin D, B12, iron, calcium, zinc and albumin across revision types — despite routine supplementation regimens — with anemia common throughout (Obesity Surgery 2025). Supplements are not a guarantee. Monitoring is what catches the gap, and monitoring means someone in the United States drawing your blood on schedule and someone reading it who understands the anatomy you now have.

You may need endoscopic surveillance, not just a scale. If your revision was driven by severe esophagitis or Barrett's, follow-up includes looking, not just weighing. ASMBS's position statement on upper GI endoscopy around bariatric surgery covers the rationale for postoperative surveillance of exactly these findings (SOARD 2021). That surveillance happens where you live.

Now the honest limits, which is what you should be shopping for. I can't order labs in the United States. I can't admit you to a US hospital. If something acute happens to you at month eight, you are going to your local emergency department, and the physician meeting you there needs to know what anatomy is inside you before they open anything or scope anything. So before you fly home you should leave with your operative report, and you should have a primary-care physician or bariatric program at home who has agreed to receive it. I'll answer your messages at any hour and I'll talk to your doctor if they want to call. What I can't do is be in the room. Any surgeon who implies otherwise across a border is overselling.

Get that arrangement in writing before your second operation, not after. That's the thing the first one taught you.

10 · Straight answers

Ask me anything. Straight answers.

Can a stretched gastric sleeve be tightened?

Yes — that operation is called a re-sleeve gastrectomy, and it's the least invasive of the revision options. Pooled data across ten studies and 300 patients put the leak rate around 2.0%, overall complications around 7.6%, and mean excess weight loss around 61% over one to three years of follow-up (SOARD 2020). The trade-off is durability: in a network meta-analysis of revisions after failed restrictive surgery, re-sleeve was the option most burdened by weight regain, while conversion to SADI-S carried far lower odds of regaining (International Journal of Surgery 2022). Re-sleeve also does nothing for reflux. Dr. Lomelí performs re-sleeve, and it is the revision he recommends least. Which one fits you depends on what your endoscopy and imaging show.

Is endoscopic sleeve gastroplasty an option after I've already had a gastric sleeve?

Not as a study-supported revision. Endoscopic sleeve gastroplasty was tested in a randomized trial as a first procedure — against lifestyle changes alone, in people with class 1 and class 2 obesity — where it produced mean excess weight loss of 49.2% at 52 weeks (The Lancet 2022). It's a primary procedure. In the setting where endoscopic revision has the most published experience — weight regain after gastric bypass — a 2023 systematic review found endoscopic techniques gave weight loss that was modest and temporary compared with surgical revision (Obesity Reviews 2023). Endoscopy matters enormously in your workup. As the treatment for a failed surgical sleeve, it is a relative contraindication due to stenosis risk and other complications — it would never be recommended as a revision procedure. We do perform ESG with Dr. Lomelí's endoscopy team as a first procedure, only at the patient's request, since it is not superior to the laparoscopic sleeve.

Can I get a gastric plication after a failed sleeve?

In practical terms, no. Gastric plication folds the greater curvature of the stomach inward and sutures it in place — and your sleeve gastrectomy permanently removed that part of the stomach, so there's nothing left to fold. Even as a first operation, sleeve gastrectomy outperformed plication on excess weight loss at 1, 3, 6, 12 and 18 months across 18 studies and 1,329 patients (Obesity Surgery 2021). If someone has quoted you a plication as a revision after a sleeve, ask them to explain what they believe your current anatomy is.

How soon after my sleeve can I be evaluated for revision?

You can be evaluated at any point — evaluation is not surgery. But most rapid weight loss happens in the first six months and weight typically settles around month 18, so if you're seven or eight months out I'm generally not calling anything a failure yet. The exception is reflux. New or worsening reflux after a sleeve gets worked up on its own timeline, because severe esophagitis and Barrett's are findings you don't wait out.

What drives the cost of gastric sleeve revision surgery in Mexico?

Which revision you actually need, how difficult your abdomen is after the first operation, whether a hiatal hernia repair is added, which hospital and how many nights you stay, what workup you still need, and the follow-up program. Most of those are unknown until someone has looked at your anatomy with endoscopy and imaging — which is why I don't publish a number and why a figure quoted before an evaluation isn't really a price. Send me your details and I'll tell you what your case needs; cost is discussed once there's a case to discuss.

Do I need a new endoscopy if I already had one before my first surgery?

Yes. That endoscopy described a stomach that no longer exists. Revision planning depends on what your anatomy looks like now — a dilated sleeve, a hiatal hernia, esophagitis, Barrett's, an ulcer — and those findings can change which operation I'd recommend (ASMBS position statement on upper GI endoscopy before and after metabolic and bariatric surgery, SOARD 2021). It's also worth knowing the endoscopy has limits: with the operating room as the reference standard, preoperative endoscopy detected hiatal hernias with 75.68% sensitivity, meaning close to one in four were only found intraoperatively (Chan et al., JGH Open 2020). The plan is built from the studies; part of it is finalized inside.

What if I had my sleeve in another country and don't have my records?

It's not a dealbreaker. If you have the operative report, send it — it tells me what was actually done rather than what you were told was done, and it can spare you repeated studies. If you don't have it, the endoscopy and imaging will map your current anatomy anyway. What I do need from you is honest history: what procedure you were told you had, roughly when, your lowest weight afterward, and anything that went wrong in recovery.

Who manages my labs and supplements once I'm back in the US?

You do, with a physician where you live — and you should line that up before your operation, not after. A 2025 meta-analysis of 14 studies and 1,049 patients revised after sleeve gastrectomy found deficiencies in vitamin D, B12, iron, calcium, zinc and albumin persisting across revision types despite routine supplementation, with anemia common (Obesity Surgery 2025). I stay reachable directly and I'll speak with your doctor, but I can't order labs or admit you in the United States. Fly home with your operative report and a named local physician who has agreed to receive it.
