Improved Mini Bypass in Tijuana, Mexico
The mini gastric bypass, known medically as the one-anastomosis surgery, is a modification of the RNY gastric bypass. It is also called the omega loop because it makes a loop when bypassing the intestines. In 1997, a doctor named Dr. Rutledge from the United States began performing this operation, and just ten years ago, they were approved at Mexico Bariatric Center®.
Results typically include rapid weight loss as well as noticeable relief from obesity-related health problems like sleep apnea, type II diabetes, hypertension, asthma, and high blood pressure. Mini-gastric bypass surgery is proven highly effective in limiting food intake, reducing caloric intake, and altering fat and sugar absorption. As a metabolic surgery, up to 90-95% of patients that take medication to control an obesity-related health issue do not need to take more pills long-term post-operatively.

Is Mini Bypass Right for Me?
The Mini Gastric Bypass (MGB) is a powerful weight loss procedure that is similar to the gastric bypass. This weight loss surgery is quickly growing in popularity, as being one of the safest and most effective forms of bariatric surgery. To qualify for mini bypass in Mexico, you must have a body mass index (BMI) of 30+.
- Safe, highly recommended surgery
- Faster recovery time compared to gastric bypass and duodenal switch
- High success rate and significant weight loss
- Strongly requested by past patients
- One of the most effective surgeries to revise and rescue previous bariatric procedures
Is Mini Gastric Bypass Safe?
As a perfect combination of two popular surgeries, the mini gastric bypass only reroutes a single anastomosis (connection) of the small intestine instead of the standard double anastomosis found in gastric bypass and duodenal switch.
In the RNY we need to make another connection between the same small bowel but it is for the bile duct. Instead of having two potential areas of a leak or bleeding, the mini bypass just has one. This makes it safer, reduces operating time, and lowers complication rates than standard bypass surgery.
One of the major concerns of medical patients traveling to Mexico for weight loss surgery is the surgeon’s qualifications. Mexico Bariatric Center works with exclusive surgeons who perform a maximum of 3-4 surgeries per day for the safety of patients. The surgeon’s experience and skills contribute to high patient outcomes.
Mexico Bariatric Center uses full-service hospital facilities with ICU specialized in bariatrics. That is why the MBC complication rate is way below the United States and Canada.

Major Benefits of Mini Gastric Bypass
A questionnaire provided by SurveyMonkey yielded the following information. The average BMI before the operation was 46, and the average hospital stay was only 3 days. In 91 percent of patients, diabetes had resolved itself within one year. Experts came to the conclusion that GERD is improved by MGB and fewer ulcers occurred compared to those after RYGB.
- Useful in resolving Gastro-Esophageal Reflux Disease or GERD.
- High success rate and significant weight loss
- One of the most effective surgeries to revise sleeve gastrectomy and Lap-Band

Surgical Steps of the Premium Mini Gastric Bypass
There are two components created by this laparoscopic operation. The first is that the gastric pouch has less curvature and is thereby more restrictive. The second is a jejunal bypass that is 200 cm or longer and features a single anti-colic gastrojejunostomy anastomosis, leading to a significant reduction in fat absorption. The surgeon inserts an endoscopic cutter/stapler through the trocars to split the stomach into two sections. The smaller section becomes your “new stomach.” It stays connected to your esophagus and the surgeon reshapes it into a narrow tube, similar to the shape of vertical sleeve gastrectomy. The new mini bypass stomach will hold between four to six ounces of food, compared to the old stomach holding 40 ounces of food.
The lesser curvature is defined where the body and the antrum meet and the stapler division is created at a right angle from this lesser curvature, and then upwards parallel to it. The surgeon divides the stomach laterally toward the gastroesophageal junction. Unlike when it comes to the sleeve gastrectomy operation, cardio is avoided explicitly. The larger section of the stomach that was split from your “new stomach” remains intact and alive within your body. It becomes important to produce digestive fluid which will help the digestion process, although will not hold food again.
This digestive fluid travels through the small intestine, connecting to the point at which food is digested through the “new stomach”, therefore breaking down the food as it continues through the intestine. Then, the bariatric surgeon will examine the length of your small intestine, to measure the amount that will be bypassed. This section of the small intestine will include both the duodenum and a section of the jejunum. It generally is bypassed 5-6 feet from the point at which the larger stomach, or “old stomach”, connects to the small intestine.
When creating the 200 cm long malabsorptive jejunal bypass, the surgeon turns their attention to the left gutter, retracting the omentum medially so that they may identify the Treitz ligament. They run the bowel 200 cm distal to this ligament, at which point the gastric sleeve’s distal tip is anastomosed anti-colic to the jejunum end side. Your surgeon will determine the length that is bypassed based on lifestyle, habits, health, and physical condition. Finally, the surgeon begins the connection between the “new mini stomach” to the small intestine that is bypassed, using a stapler. This connection point is called an anastomosis. Once finished, the mini gastric bypass surgeon will reinforce and stabilize the anastomosis with sutures, finishing the procedure with sutures on the trocar insertion parts of your abdomen.

How Does Mini Gastric Bypass Compare?
Comparison to Gastric Sleeve – The one-anastomosis gastric bypass (OAGB) reduces the stomach size significantly while bypassing a large part of the small intestines. The gastric sleeve procedure, however, completely removes 80% of the stomach, instead of keeping it in-place like the mini gastric bypass.
Comparison to Gastric Bypass – Gastric Mini Bypass is a modified version of Gastric Bypass working in similar ways. The Roux-en-Y Gastric Bypass (RYGB) has two anastomoses, while the mini gastric bypass only has one. The “new stomach” in mini-bypass is created along the lesser curvature of the patient’s stomach. The mini-gastric bypass is also less likely to stretch. The mini-gastric bypass has higher rates of marginal ulceration (MU) as ulcers may occur after this operation.
A surgeon from Taiwan, Wei-Jei Lee, made a comparison between RYGB and the MGB after performing over ten years of the surgeries. He believed that MGB was safer and simpler and that it produced better results when it came to diabetes reduction, GLP-1 elevation, and long-term weight loss.
Is Mini RNY Surgery Dangerous?
There are two components created by this laparoscopic operation with minimal scarring.
- The gastric pouch in the shape of a tube is created to cause restriction. The new mini bypass stomach will hold between four to six ounces of food, compared to the old stomach holding 40 ounces of food. The larger section of the stomach that was split from your “new stomach” remains intact to produce digestive fluid.
- A jejunal bypass that features a single gastrojejunostomy anastomosis is performed. The rerouting leads to a significant reduction in nutrition and fat absorption.
The number of OAGB procedures performed has increased dramatically worldwide since it was conceived in the United States 18 years ago by a well-known doctor named Robert Rutledge. In the early stages of the mini gastric bypass surgery, there was a lot of resistance from surgeons who had been performing longer procedures with greater difficulty. The surgeons are finding that this procedure is technically straightforward, rapid, efficient, and safe.
Even though MGB has been recognized as a simple procedure, the operation can lead to severe complications in the hands of doctors with insufficient understanding of the underlying anatomy and physiology.
The process also offers a single anti-colic anastomosis that, in the prevailing view, results in less leakage. The absence of any leaking issues and a bypassed length that can be modified based on the BMI of the patient. This procedure results in durable weight loss that can be reversed or revised as needed.
Expected Weight Loss
The %EWL was: one year at 76%, two years at 85%, three years at 78%, four years at 75%0, five years at 70%, and beyond 5 years at 70%. In 14% of patients, there was a failure to lose less than 50% of excess weight in 5 years. There has been a 0.2% 30-day mortality rate.
- 3 months post-op: 35%-37% excess weight loss*
- 6 months post-op: 55%-60% excess weight loss*
- 12 months post-op: 73% excess weight loss*
- 18 months post-op: 78% excess weight loss*
Mini Gastric Bypass Side Effects
- Minor Side Effects: Gas Pain, Bruising, Nausea, and Inflammation, short-term hair loss
- Severe Side Effects: GERD/Gastritis, Bile Reflux, Pneumonia, Blood Clots, and Gallstones
Mini Gastric Bypass Complications
- Short-Term: Bleeding and Leak (rate of 1.06%)
- Near-Term: Stomach Obstruction, Stricture, or Abdominal Abscess
- Long-Term: Delayed Leak
Digestion Process Changes in MGB
The Normal Digestion Process – In the typical process of digestion, food begins in your mouth, goes down through the esophagus, then reaches your stomach. As the food gathers in your stomach, it combines with acids and enzymes that aid in digestion. The gallbladder (holds bile produced by the liver) and the pancreas also create and release digestive juices to help aid in digestion, which connects to the small intestines through the pylorus.
As food breaks down, the particles get released into the first part of the small intestine (duodenum) and continue to the second part of the small intestine (jejunum). Almost all the calories, nutrients, and important enzymes are absorbed within the duodenum and jejunum while most of the leftover particles go through the digestive tract and get wasted.
The New Digestion Process – After the mini gastric bypass surgery, the new stomach will hold significantly less food which creates the feeling of being full. Next, as the food exits the new stomach, it reroutes so it does not go through the duodenum and avoids most of the jejunum. Because of this, fewer calories and nutrients are absorbed, while also having most of the same digestive fluid break down the food particles.
MGB is a modification of the original Billroth II procedure. The surgeon will determine the length that is bypassed based on lifestyle, habits, health, and physical condition. In people who are very tall or especially obese, the surgeon may opt for 250 cm or more rather than the traditional 200 cm distal to the Treitz ligament.
Different modifications of this surgery have had different results, and it was found that placing the anastomosis between 200 cm and 300 cm proximal to the body’s ileocecal valve would be ideal for maintaining an adequate level of nutrition.
It is possible for the MGB operation to be modified if there is inadequate weight loss or an excess amount of weight loss. This involves moving the anastomosis either proximally or distally.
