Fundoplication Revision to Gastric Bypass
Had a Nissen fundoplication, then regained weight and lost your reflux control? Dr. Alejandro López undoes the prior fundoplication and converts the anatomy to a Roux-en-Y gastric bypass — in a single laparoscopic operation.

A Nissen or Toupet fundoplication wraps the upper stomach around the lower esophagus to recreate the antireflux barrier. It works well for years in most patients — but when weight gain, abdominal pressure, or a recurrent hiatal hernia disrupt the wrap, reflux returns. Combine this with obesity-related metabolic problems and patients often find themselves needing both antireflux relief AND weight loss surgery.
Performing two separate operations — a fundoplication revision and then a bariatric procedure later — is risky, expensive, and recovery-heavy. Dr. Alejandro López combines both into a single laparoscopic operation.
How the Single-Stage Conversion Works
The procedure has three coordinated phases performed laparoscopically in one operation:
- Fundoplication takedown — Dr. Alejandro López carefully releases the prior wrap from the lower esophagus, preserving the diaphragmatic attachments.
- Hiatal hernia repair (when needed) — Any recurrent hiatal hernia is repaired before reconstruction.
- Roux-en-Y gastric bypass — A small gastric pouch is created and connected to a limb of the small intestine, completing the bypass.
Because the bypass anatomy diverts acid downstream and the small pouch produces very little acid, reflux is controlled by the new anatomy itself — no wrap or fundoplication required.
Who Is a Candidate?
- Patients with a prior Nissen or Toupet fundoplication who experience reflux relapse
- Patients with significant weight regain following fundoplication
- Patients with BMI ≥ 35 (or ≥ 30 with comorbidities) and persistent GERD symptoms
- Patients fit for laparoscopic surgery (cleared by preoperative evaluation)
PRICING · ALL-INCLUSIVE PACKAGE
How Much Does Nissen Reversal to Gastric Bypass Cost?
Nissen takedown + Roux-en-Y gastric bypass in a single laparoscopic operation. All-inclusive surgical package — pricing varies by ALO Bariatrics location.
| Location | Price (USD) |
|---|---|
| Tijuana | from $6,700 |

How the price is built: The fee is the Roux-en-Y gastric bypass package price + $800 USD for the fundoplication takedown step.
- Tijuana: $5,900 (bypass) + $800 (takedown) = $6,700
- Puerto Vallarta: $6,600 (bypass) + $800 (takedown) = $7,400
- Guadalajara: $6,600 (bypass) + $800 (takedown) = $7,400
