A failed sleeve, regained weight, severe reflux after a sleeve, an old lap-band that's slipped — there's a path forward, and we've walked it with thousands of patients before you. Revision surgery is a second chance, done by surgeons who specialize in fixing what didn't work the first time.
If you're here, you've probably been told something like "you should have tried harder." You didn't fail. Roughly 1 in 5 bariatric patients needs some form of revision over their lifetime — and it almost never has to do with willpower. It usually means the original tool wasn't matched to your body, or the anatomy stretched, or a complication developed.
The good news: revision surgery, when done by an experienced team, can deliver dramatic and lasting results. Sleeve patients converted to bypass typically lose another 60–70% of their remaining excess weight. Lap-band removals give patients their lives back. Re-sleeves restore the restriction that stretched out over time.
Every revision case is unique. Here are the four most common paths we perform — your coordinator will recommend the right one after Dr. Pasten reviews your medical records and prior operative report.
The most-performed revision. For patients who lost too little, regained too much, or developed severe reflux after a sleeve. The bypass adds malabsorption + metabolic effect to fix what the sleeve alone couldn't.
When the original sleeve has stretched and lost its restriction, a re-sleeve trims the stomach back down to the proper banana shape. Less complex than conversion to bypass — same recovery as a primary sleeve.
Lap-band is largely retired in modern bariatrics. Most patients eventually need it removed — and many opt to convert directly to a sleeve or bypass in the same surgery. We do both stages in one OR session whenever it's safe.
For some bypass patients with mild regain and a slightly stretched pouch, an endoscopic procedure can tighten the pouch outlet without re-doing the surgery. Recovery is faster — but the effect is more modest than full revision.

Revisions are inherently more complex than first-time surgeries. We're careful — and that's a good thing. Here's what we look for.
We're going to be direct, because you deserve to know. Revisions are not the same as primary bariatric surgery, and you should hear that from us before you commit.
Revision surgeries typically take 30–60% longer than the equivalent primary procedure because of scar tissue and altered anatomy. Surgery time isn't a measure of risk on its own — but it's why surgeon experience matters even more.
Revision complication rates are 2–3x higher than primary surgery in any surgeon's hands — that's just surgical reality. In experienced revision-volume hands, it's still a low absolute number (well under 10%). Every revision at Pompeii is backed by complication insurance.
We require your operative report and current imaging before we can approve any revision. This is non-negotiable and it protects you. If you don't have these, we help you get them.
Most revisions stay 3 nights instead of 2 in the hospital, and patients fly home day 5–6 instead of day 4–5. Plan an extra few days off work compared to a primary procedure.
In revision surgery, "who" matters more than the price. Dr. Pasten specializes in bariatric and metabolic surgery at Hospital Bellas Artes, with formal CMCOEM certification and general surgery training that directly covers the complex anatomy of revision cases. Pick a surgeon who is specifically qualified for your revision.
If your records show a revision isn't safe — staple-line scarring, very recent prior surgery, uncontrolled medical conditions — we tell you. We've turned away cases where the right answer was to wait or pursue a different path. That's part of how we keep our outcomes where they are.
U.S. self-pay revision surgeries average $25,000–$35,000 — when surgeons will perform them at all. At Pompeii, what you see is what you pay.
Revisions follow a similar path to primary surgery — with one critical addition at the front: medical record review. Here's exactly how it unfolds.
Apply online and email us your operative report from the prior surgery, plus any recent upper-GI imaging. If you don't have these, we'll help you request them from your previous surgeon. This is the most important step — it's how we know whether revision is safe and which path is best.
Your records are reviewed by our bariatric surgical team. Within a few business days you'll get an honest answer: which revision (if any) is right, what the expected results look like, and any concerns we see. If we don't think revision is safe yet, we'll tell you.
Once approved, your coordinator schedules your surgery date, sets up financing (if needed), and provides your detailed pre-op instructions. Most revision patients fly within 3–5 weeks of approval.
Revision patients typically follow a slightly longer pre-op liquid diet than primary patients (3 weeks vs 2). This is critical for safe revision surgery — a smaller liver gives the surgeon more room to work around scar tissue.
San Diego pickup, drive to Tijuana, final labs, surgery the next morning. Most revisions stay 3 hospital nights (vs 2 for primary). Our 24/7 bariatric nursing team monitors you closely. Your surgeon rounds personally.
Once cleared, you transfer to a luxury hotel near the hospital for one final night of comfort and observation before flying home. (We'll keep you in the hospital longer if there's any reason to.)
Revision patients get more intensive post-op coordination — weekly check-ins for 8 weeks (vs 4–6 for primary), nutritionist support, and access to the 70,000+ private community. We see this through.
Because revisions carry slightly elevated risk, our protection matters more, not less. Complication insurance is included at no extra cost with every revision — surgical costs, extended hospital stays, additional nursing, even flight and hotel rebooking. And a full refund if your records show revision isn't safe to proceed.
Verified stories from Pompeii revision patients — sleeve conversions, lap-band removals, and re-sleeves.
"I thought I'd failed. Turns out, I just had the wrong tool."
My sleeve from another clinic plateaued at 30 lbs lost. Pompeii reviewed my records and recommended bypass. Six months later I'm down another 80 lbs. I should have gone here first.
"Got my band out after 11 years."
My lap-band had slipped twice. Three U.S. surgeons quoted $30k+ to remove and convert. Pompeii did the band removal and sleeve conversion in one operation, all-inclusive. Game changer.
"Reflux gone after sleeve-to-bypass."
Severe GERD started 2 years after my sleeve. PPIs stopped working. Pompeii converted me to bypass — reflux was gone within a month and I lost another 45 lbs as a bonus.
"They told me 'not yet' — and they were right."
I wanted a re-sleeve right away after gaining weight back. My Pompeii surgeon reviewed my records and said wait 6 months, fix my eating habits first. He was honest with me. We did it the right way.
