What is a mini gastric bypass?
A mini gastric bypass, or OAGB (one-anastomosis gastric bypass), is a weight-loss surgery that makes a long, narrow stomach pouch. The pouch is joined to a loop of your small intestine with one connection. That means you eat less and absorb fewer calories. It's on the American Society for Metabolic and Bariatric Surgery (ASMBS) list of endorsed procedures.
- A note on names: "mini sleeve" isn't a standard procedure name. If you've seen it, ask our coordinators whether you mean a gastric sleeve, a One-Port Sleeve or this mini bypass.
How does a mini gastric bypass work?
Your surgeon creates a long, narrow pouch and joins it to the small intestine farther down, skipping part of it. A traditional gastric bypass uses two connections; a mini bypass uses one.
Who is a mini gastric bypass usually for?
A mini gastric bypass is often discussed for adults living with obesity and related conditions who haven't reached their goals with other approaches. Your surgeon reviews your health history, tests and goals, then decides what's right for you.
- Current ASMBS and IFSO guidelines (2022) look at your weight together with related diseases, for example type 2 diabetes.
What do studies say about a mini bypass?
A mini bypass is newer in the U.S. than a sleeve or traditional bypass. A 2025 IFSO review found it wasn't worse than a traditional bypass for weight loss or for type 2 diabetes. Each figure below names its measure, time point and source.
- Excess weight loss: an average of 75% at 5 years, in a 2026 review of 32 studies with more than 19,000 people (OAGB long-term review).
- Excess BMI loss: an average of 87.9% at 2 years after a mini bypass and 85.8% after a traditional bypass, in one 2-year trial (YOMEGA, Lancet, 2019).
Mini bypass vs traditional bypass, in one 2-year trial
| What was measured | Mini gastric bypass | Traditional gastric bypass |
|---|---|---|
| Connections | One | Two |
| Excess BMI loss at 2 years | 87.9% | 85.8% |
| Reversal | Can be converted or sometimes reversed, as a new operation | Difficult to reverse (NIDDK) |
Source: YOMEGA trial, Lancet, 2019. The mini bypass in this trial skipped a 200 cm length of intestine; your surgeon's plan may differ.
How does a mini gastric bypass compare with other surgeries?
A mini bypass has one connection and a traditional bypass has two. A trial found similar weight loss and metabolic improvement at two years. A sleeve doesn't reroute your intestine. Your surgeon helps you choose.
| Procedure | How it works | Reroutes intestine? | Reversible? |
|---|---|---|---|
| Gastric sleeve | Removes most of the stomach; what's left is a narrow tube | No | No |
| Dr. Serrano's One-Port Sleeve | The same sleeve, through one small incision, usually at the navel | No | No |
| Gastric bypass | Small pouch joined lower in the small intestine; two connections | Yes | Difficult |
| Mini gastric bypass | Long, narrow pouch; one connection | Yes | Can be converted, or sometimes reversed, as a new operation |
| Duodenal switch | Sleeve plus an intestinal bypass; two connections | Yes | Ask your surgeon |
| SADI-S | Sleeve plus an intestinal bypass; one connection | Yes | Ask your surgeon |
| Revision | Changes or converts an earlier surgery | Depends on the plan | Depends on the plan |

How long is the stay and recovery?
Dr. Serrano's published plan is 3 nights and 4 days: 1 hotel night before surgery and 2 nights in the hospital. Many people return to light work in about a month, once their surgeon's team clears them. Plan on about four to six weeks before heavy lifting, and only once your surgeon clears you.
Before surgery, you'll follow a pre-op diet, which can help shrink your liver. Your surgeon's team gives you a plan, including how long it lasts.
Your trip, in order:
- Pickup in San Diego and transportation to Tijuana
- Pre-op tests and labs, then a hotel night
- Your surgery, then 2 nights in the hospital
- A driver from the transportation company we hire picks you up in San Diego and drops you right back.
- Follow-up and nutrition guidance after you return home
Your diet moves in stages over several weeks, from liquids to soft foods and then solid foods, per your surgeon's plan (NIDDK). You'll take lifelong vitamins and minerals as your surgeon's team prescribes.
What happens after you're home?
After surgery, Dr. Edgar Serrano's team gives you nutrition and recovery guidance. Weight-loss surgery needs regular follow-up, vitamins and lab checks, so before you travel, plan which doctor will see you at home, and bring copies of your surgery records to that first visit.
