Improved Mini Bypass in Tijuana, Mexico

The Mini Gastric Bypass (MGB), known medically as the one-anastomosis bypass, is a modification of the RNY gastric bypass surgery. 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 over ten years ago, they were approved at Mexico Bariatric Center®.

As a metabolic surgery, up to 90-95% of bypass patients who take medication to control their obesity-related health issue, like insulin, find they no longer need these medications long-term after the operation.

Mini-gastric bypass surgery is proven highly effective in limiting food intake, reducing caloric intake, and altering fat and sugar absorption. 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.

How Mini Bypass Surgery Works

Mini gastric bypass is a restrictive as well as malabsorptive bariatric procedure. The stomach is made smaller to limit and restrict food and calorie intake. Food that enters the new stomach is rerouted to bypass the duodenum and most of the jejunum. Because of this, fewer calories and nutrients are absorbed while still creating digestive juices to break down the food.

There are two components created by this laparoscopic operation with minimal scarring.

The larger section of the stomach split from the “new stomach” remains intact and alive within your body. Although it will not hold food again, it will produce digestive fluid to help the digestion process.

Mini gastric bypass resets your metabolic system for rapid and sustainable weight loss. MGB operation leads to hormonal changes such as Ghrelin (hunger hormone), GLP-1, PYY, and GIP.

Mini Gastric Bypass Weight Loss Timeline

The mini gastric bypass procedure has become popular among bariatric surgeons and patients. It has substantial results in the first few months, equal to RNY gastric bypass, and has proven positive, long-lasting results.

After two years, many MBC’s MGB patients have achieved 85% excess weight loss (EWL). Between the 3rd and 5th year, it is typical for the EWL to level out around 70%-78%. In 14% of patients, there was a failure to lose less than 50% of excess weight within five years.

  • 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*

The numbers expressed here are only average, and it does not indicate that 100% EWL is not achievable.

Is Mini Gastric Bypass Safe?

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 Roux-en-Y, the second connection is made to bring stomach enzymes, bile, and pancreatic juice to the Y.

Instead of having two potential leak areas or bleeding; the mini bypass just has one. This makes it safer, reduces operating time, and lowers complication rates compared to standard bypass surgery.

One of the significant concerns of medical patients traveling to Mexico for weight loss surgery is the surgeon’s qualifications. Mexico Bariatric Center works with exclusive surgeons who have performed hundreds of MGB and are capped to a maximum of 3-4 surgeries per day for the safety of patients.

Pros and Cons of Mini Gastric Bypass Surgery

A study by the Department of Surgery at the Heart of Florida Regional Medical Center followed a group of mini gastric bypass patients starting with an average BMI of 46. In 91 percent of patients, diabetes had resolved itself within one year. Experts concluded that MGB improves GERD, and fewer ulcers occurred compared to those after RYGB.

Surgical Steps of the Premium Mini Gastric Bypass

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 a vertical sleeve gastrectomy. The new mini bypass stomach will hold between four to six ounces of food, compared to the old stomach which holds 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. This digestive fluid travels through the small intestine, connecting to the point at which food is digested through the “new stomach,” 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 where 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 bypass length based on lifestyle, habits, health, and physical condition. Finally, the surgeon begins the connection between the “new mini stomach” and the bypassed small intestine, 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, completing 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?

Andi-Mini-Gastric-Bypass-Surgery-Before-and-After-720x720

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 the medical community, which had been performing more prolonged procedures with incredible difficulty. The surgeons find this procedure to be technically straightforward, rapid, efficient, and safe. There has been a 0.2% 30-day mortality rate.

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 results in less leakage in the prevailing view. The absence of any leaking issues and a bypassed length can be modified based on the patient’s BMI. This procedure results in durable weight loss that can be reversed or revised as needed.

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.

Technique Modification

MGB is a modification of the original Billroth II procedure. The surgeon will determine the bypass length 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.

The MGB operation can be modified if there is inadequate or excess weight loss. This involves moving the anastomosis either proximally or distally.
