What is gastric sleeve procedure?

To understand how does gastric sleeve work, you should have a clear idea of what the gastric sleeve procedure entails?

In Mexico, this procedure is commonly performed on patients from the US and Canada. Mexico’s top hospitals will use the same surgical protocols, techniques, and quality standards as some of the best hospitals in the US.

In this procedure, the weight loss surgeon will remove a portion of your stomach. They will then suture together the remaining parts to create a new “sleeve” (banana-shaped stomach). Now with a significantly smaller stomach, you will feel fuller much more quickly than you did before.

The reduced capacity to eat will help you lose weight and maintain a slimmer body in the long run. During the surgery, the appetite-boosting hormones also get removed, which further supports your long-term weight loss.

Distinct from Gastric Bypass

While you should know how does gastric sleeve work, it is also important to understand its differences with gastric bypass surgery.

In gastric bypass, the bariatric surgeon in Mexico will create a small pouch that skips (bypasses) most of your stomach. This it will go directly to your intestine.

Compared to gastric bypass, surgeons often give preference to gastric sleeve (or sleeve gastrectomy) because it is both malabsorptive and restrictive. This means the intake of calories is diminished from the source because you feel less hungry.

History of Gastric Sleeve Surgery

To gain better insights into how does gastric sleeve work, you should have an idea about its origins.

Sleeve gastrectomy was first introduced about three decades ago to treat high risk patients who were suffering from morbid and super morbid obesity.

Before subjecting these patients to a more invasive procedure such as duodenal switch surgery or a gastric bypass, it was proposed that they should first undergo gastric sleeve surgery.

In this two-step procedure for high-risk obese patients, gastric sleeve showed highly encouraging weight loss results. That led to sleeve gastrectomy being adopted as a standalone weight loss procedure.

Since 2003, this procedure has been performed on thousands of patients as an independent bariatric surgery with outstanding results.

The American Society for Metabolic and Bariatric Surgery (ASMBS) finally changed its official position gastric sleeve surgery.

In 2012, it recognized sleeve gastrectomy as both a primary bariatric surgery and a first phase in a two-step weight loss surgery.

How does gastric sleeve surgery work?

To address the patient’s concerns, an experienced weight loss surgeon in Mexico will first explain how does gastric sleeve surgery work.

The process begins with some advance preparation as follows:

  • Learn about Mexico gastric sleeve surgery as much as possible, and make a commitment to adopt a healthy diet and lifestyle after the surgery.
  • Follow the pre-operative care instructions of your Mexico bariatric surgeon to avoid smoking before the procedure.
  • Stop taking any blood thinning medications and herbal supplements for a few days prior to surgery.
  • In the weeks or months leading up to your surgery, try to eat a more balanced diet and maintain an active lifestyle as far as possible.
  • Make post-surgical care arrangements in advance. These would include having a ready supply of liquid diet and any essential medications as advised by the surgeon.

During the Surgery

  • After you are wheeled into the operating room, you will be placed under general anesthesia. This will keep you asleep completely comfortable throughout the procedure. You will have no recollection of the surgery when you wake up.
  • The surgeon will begin the procedure by making multiple small incisions in the upper abdominal area. The incisions will be placed in discreet locations to minimize any post-surgical scarring.
  • If your gastric sleeve surgery is performed laparoscopically (most advanced surgery centers will use laparoscopy like the US hospitals), the surgeon will insert a small laparoscope and tiny surgical tools through the incisions.
  • At this point, the anesthesiologist will pass a thin sizing tube down your mouth into the stomach.
  • Now the surgeon will make use of a laparoscopic stapler to bifurcate the stomach (resulting in a narrow vertical sleeve).
  • The portion of the stomach that has been removed will be taken out through an abdominal incision.
  • Your surgeon will now test the sleeve for any leaks using an upper endoscopy or a dye study.
  • The incisions will be carefully closed with dissolvable sutures or tape.

Requirements for gastric sleeve surgery

In addition to obtaining a clear idea about how does gastric sleeve work, you should also be aware of what would qualify you as a suitable candidate.

Should I Choose Gastric Sleeve Surgery?

Gastric sleeve surgery is designed to restrict the amount of food you eat, but without interfering with food absorption. It also does not involve the placement of any foreign body inside your stomach. If these attributes appeal to you, gastric sleeve surgery might be the right option for you.

Compared to gastric bypass, the weight loss in case of gastric sleeve surgery will be more gradual. Like any other bariatric surgery, you will have to commit to a healthy diet and exercise plan for the long-term.

It’s also vital to know that sleeve gastrectomy is a permanent, irreversible procedure.

You should carefully consider the pros and cons of each type of bariatric surgery with your surgeon before making a decision.

Am I a Good Candidate for Gastric Sleeve Surgery?

Individuals with a body mass index (BMI) of 40 or higher are usually sound candidates for gastric sleeve surgery.

In other words, you may be at least 100 pounds above your ideal body weight to qualify for this procedure. If you suffer from a medical condition that could improve with weight loss, you may even qualify with a BMI of 35.

Patients suffering from heart disease, type 2 diabetes, or sleep apnea are usually recommend sleeve gastrectomy if their BMI is at least 35. Individuals with extremely morbid obesity (BMI of 60 or higher) may also be candidates for gastric sleeve surgery.

How long does gastric sleeve surgery take?

Apart from knowing how does gastric sleeve work, you should know how much time will gastric sleeve take inside the operating room? An experienced bariatric surgeon in Mexico would be able to complete the surgery within one to two hours.

The precise duration of surgery can vary from one patient to another, depending on the complexities of a particular case.

In any case, with advanced laparoscopic techniques, the surgery is now performed faster. It involves no bypass or intestine removal, which also reduces the surgical time. Recovery after a gastric sleeve is also relatively faster, and you can leave the hospital the same day or next day.

Following gastric sleeve surgery in Mexico, you can lose about two-third of your excess weight in the first 6 to 12 months. It’s critical to follow the surgeon’s post-op guidelines to achieve the best results.
