Mini Gastric Bypass (MGB), also known as Single-Anastomosis Gastric Bypass, is a powerful weight loss procedure that utilizes both restriction, similar to gastric sleeve, and malabsorption, similar to gastric bypass, to help stimulate fast and effective weight loss.

The surgery works by creating a sleeve-shaped upper portion of the stomach and then reconnects the smaller stomach to a bypassed portion of the small intestines – ultimately restricting food intake and reducing caloric intake. Patients can expect to lose 60-80% of excess weight in the first year.

Mini Gastric Bypass Surgery Details - Mexico Bariatric Center

Is Mini Gastric Bypass in Mexico 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. This makes it safer and even is more successful at reducing obesity than the 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.

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.

Major Benefits of Undergoing 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.

Details and Duration of Mini Gastric Bypass

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.

Is Mini RNY Surgery Dangerous?

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.

The process also offers a single anti-colic anastomosis that is in 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.

Mini Gastric Bypass Side Effects

  • Severe Side Effects: GERD/Gastritis, Pneumonia, Blood Clots, and Gallstones

Mini Gastric Bypass Complications

  • Short-Term: Bleeding and Leak (rate of 1.06%[4])
  • Near-Term: Stomach Obstruction, Stricture, or Abdominal Abscess
  • Long-Term: Delayed Leak

Steps During Mini Gastric Bypass Procedure

These are the official steps bariatric surgeons follow to ensure the most effective, safe, and successful results for mini gastric bypass surgery.

Step 1: Patient is lying face up.
Step 2: General anesthesia is administered by the anesthesiologist and a breathing tube (endotracheal tube) is inserted into the esophagus.
Step 3: Surgeon makes 3 to 5 very small incisions on the abdomen.
Step 4: The abdominal cavity is filled with CO2 in order to have room to comfortably perform the procedure.
Step 5: Place five trocars (hollow tubes) in your abdomen through small incisions.
Step 6: Insert an endoscopic cutter/stapler as well as other instruments through the trocars.
Step 7: Split the stomach into two sections laterally toward the gastroesophageal junction. The smaller section becomes your “new stomach.“
Step 8: Measure small intestines to become a bypass point (200 cm or longer).
Step 9: The bypassed section of the small intestines connects to the new stomach. This connection point is called an “anastomosis.”
Step 10: The anastomosis is reinforced with sutures.

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 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.
