For decades, Dr. Michel Gagner has performed life-saving bariatric surgeries all over the world with long-term results. Using innovative weight-loss procedures, some of which he himself has pioneered or perfected, Dr. Gagner has managed to give patients hope for better health when diet and exercise alone has not been enough to lose significant weight. He is known for performing minimally invasive procedures, and his renowned techniques are taught and studied in universities and other academic settings.

Obesity in the United States

In the United States, almost 38% of adults are obese. Almost 8% are morbidly obese. Preventable chronic diseases associated with obesity are the biggest cost to healthcare in this country. Up to $210 billion dollars are spent on healthcare costs for diseases such as diabetes, heart disease, stroke, hypertension, and cancers. In 2017, 14.8% of high-school students were obese. While a healthy diet and exercise are essential to maintaining a healthy body mass index, our country needs more permanent obesity solutions. Despite an obese person’s best efforts to lose weight, their goals may not be achievable without bariatric surgery.

The truth of obesity in the USA is that it isn’t always a result of a series of poor lifestyle choices. Studies show that eating high-sodium, high-sugar diets and inactivity don’t always lead to obesity. Excessive weight is often a result of genetics and are beyond the individual’s control. Dr. Gagner and his team have helped thousands of patients in the US and all over the world reach their weight-loss goals by first making them feel comfortable and open to discuss their hopes and expectations for a better, healthier future.

Weight Loss Procedures

Gastric Balloon

The gastric balloon is an inflatable balloon that is placed into the stomach temporarily. By reducing the available space in the stomach, patients feel full after having eaten less food. In addition, the balloon results in delayed emptying of the stomach, allowing for longer periods between meals. Weight loss is achieved by restricting daily caloric intake because of patient fullness. This is a great option to compliment a weight loss program or lifestyle changes to result in long term weight loss. Many patients who are not good candidates for surgery may choose this option. The procedure is an out-patient procedure, with patients leaving the clinic the same day of the procedure. The balloon is inserted by gastroscopy through the mouth under general anaesthesia, with no need to operate the stomach in any way. Patients may return to work within a few days after the procedure.

Aspire Assist

The AspireAssist is a new form of treatment for obesity. The treatment works by giving the patient the ability to empty about 30% of his or her stomach safely and easily after meals. A tube (PEG) is installed by gastroscopy and under sedation from the patient’s stomach to her abdomen with a port attached on the outside of the abdomen. A pump can be used after every meal to remove a large portion of the meal before the calories are absorbed, leading to significant weight loss. Patients will require a new kit every year in order to be able to continue to use the AspireAssist.

Laparoscopic Sleeve Gastrectomy

Laparoscopic Sleeve Gastrectomy

Dr. Gagner was the first surgeon to pioneer the use of laparoscopic Sleeve Gastrectomy (LSG), also known as gastric sleeve surgery, as a first-step in weight-loss interventions in high-risk patients. Since Dr. Gagner began performing this procedure in 2000, LSG has become a popular option for both patients with high risk due to co-morbidities and weight, and patients with low BMI as an alternative to gastric banding.

Mini Gastric Bypass

The Mini Gastric Bypass (MGB) combines gastric reduction and intestinal malabsorption to achieve weight loss. The procedure involves creating a small gastric pouch near the esophageal sphincter. The first part of the intestine is attached to the newly formed gastric pouch about two meters down the intestine.

Laparoscopic Roux en Y Gastric Bypass

Laparoscopic Roux-en-Y Gastric Bypass

Dr. Michel Gagner has been an instrumental agent in the evolution of the Gastric Bypass (GB) procedure into what it has become today. His team performed the second GB while he was working at the Cleveland Clinic in "95, and was the first to perform a hand-assisted GB in "96. He brought forth multiple modifications that were adopted worldwide and have become standard: the use of an antecolic and antegastric limb in "96, the use of a split omentum in "96, and the use of trans-oral techniques. Dr. Gagner is also an experienced revisionist of the GB, being the first surgeon to convert both a gastric band and a VBG into a GB by laparoscopy in "96.

Single Anastomosis Duodenal Switch

Single-Anastomosis Duodenal Switch

Single anastomosis duodenal switch (SIPS) primarily depends on intestinal malabsorption, but also utilizes gastric reduction to achieve weight loss. Firstly, a sleeve gastrectomy is performed to reduce the size of the stomach. The lowest part of the intestines, the ileum, is left undivided, but the duodenum is separated, leaving a small segment attached to the stomach and a longer free-hanging segment to which the liver and pancreas are attached. The ileum is brought up and re-connected to the duodenum segment. Digestion of protein and fat only occurs in the lower portion, about 7 feet long, of the lower intestines.

Duodenal Switch

Duodenal Switch

Dr. Gagner was the first surgeon to perform the Duodenal Switch (DS) laparoscopically during the summer of "99. Since then, he has continued to innovate with this surgery. He was the first surgeon to perform a DS in two stages in "00. He was also the first surgeon to convert a gastric Lap Band and a gastric bypass into a DS.



With all the years of experience Dr. Gagner has accumulated, it is no wonder he is one of the world’s foremost experts in highly complex bariatric surgery revision procedures. Dr. Gagner can accommodate for most patient cases. Once he has a chance to learn the peculiarities of a case, he can advise for the best course of action. While no two revisions are the same, there are some types of revisions performed more often than others...

General Surgery

Diagnostic Surgery

Diagnostic surgery is performed only for diagnostic purposes, without the intention of treating any disease at the time of surgery. Diagnostic surgery is often necessary when imaging techniques have been unsuccessful in identifying the issue or the cause of pain, and direct vision is required. All diagnostic surgeries are done by laparoscopy and are out-patient procedures, with patients able to leave the clinic the same day as the surgery.

Hernia Repair

A hernia is a weakness of the abdominal wall causing a protrusion of an organ where it does not belong. There are many types of hernias, but the most common ones involve a weakening of the abdominal wall leading to organs bulging through, and causing immense pain. Dr. Gagner repairs multiple types of hernias including hiatal, inguinal, femoral, umbilical, Spigelian, incisional and lumbar hernias. All repairs are done by laparoscopy and often include permanent sutures and/or a mesh. Hernia repairs are out-patient procedures, with patients leaving the clinic the same day of the procedure. Patients need a minimum of 1 week of convalescence to recover from the surgery.


The gallbladder is responsible for storing bile, the fat-digesting liquid produced by the liver. Over time, gallstones can form from the crystallization of bile components. Most people never have symptoms caused by the stones, until the onset of excruciating pain caused by a gallstone attack (biliary colic). Once symptoms develop, the only viable treatment is to completely remove the gallbladder. This surgery is called a cholecystectomy...

Nissen Fundoplication

The first symptom of gastric reflux is often heartburn and acid indigestion. Over time, issues with the lower esophageal sphincter can lead to Gastroesophageal reflux disease, or GERD. GERD can be treated with medication, such as antacids. proton pump inhibitors, and H2 blockers, but patients may be interested in more permanent solutions...



Endoscopies involve introducing a camera into the patient for diagnostic or exploratory purposes. Gastroscopies are endoscopies done by way of the patient’s mouth, and into the esophagus, stomach, and upper portion of the intestines. The procedure can be done under local anesthesia or general sedation...
