Sleeve Gastrectomy

Introduction

A surgical weight-loss surgery called a sleeve gastrectomy removes almost 80% of the stomach, leaving behind a tube-shaped stomach that is roughly the size and shape of a banana. Another name for a sleeve gastrectomy is a vertical sleeve gastrectomy. Usually, this operation is carried out laparoscopically, which includes inserting tiny instruments through several tiny incisions in the upper abdomen.

Reducing the size of your stomach limits how much food you can eat. Furthermore, the process triggers hormonal adjustments that aid in weight reduction. These same hormonal shifts also aid in the treatment of heart disease and high blood pressure, two disorders linked to obesity.

In the United States, gastric sleeve surgery, commonly known as sleeve gastrectomy, is the most popular weight loss technique. It is quick and simple for skilled bariatric surgeons to do, and if you have certain high-risk medical conditions, it might be advised. Additionally, your surgeon might suggest it if your BMI is at the low end of the range for candidates for weight loss surgery or extremely high. The gastric sleeve operation can be used alone or in conjunction with a duodenal switch procedure to aid in weight loss.

A minimally invasive treatment called a sleeve gastrectomy involves removing the majority of the stomach. Less food can be stored in the sleeve-shaped pouch, which is a long vertical tube made out of the remaining stomach.

This surgery preserves the duodenum, the portion of the stomach that connects to the start of the small intestine. By doing this, “dumping syndrome,” which happens when your stomach’s undigested contents pass too quickly into your small bowel, is avoided. Dumping syndrome may result in diarrhea, nausea, and cramping.

Like other bariatric surgery procedures, sleeve surgery causes you to eat less and feel fuller after consuming smaller portions of food.

Following a sleeve gastrectomy, patients should eventually shed roughly 60% of their excess body weight. Losing weight after a sleeve gastrectomy may help individuals live longer, healthier lives by reversing and/or lowering their future risk of developing chronic obesity-related illnesses such type 2 diabetes, high blood pressure, and/or sleep apnea.

What is surgery for gastric sleeves?

A surgical treatment called gastric sleeve surgery, sometimes known as sleeve gastrectomy, can assist an obese person in gradually losing extra weight. Fifty to seventy-five percent of the patient’s stomach is surgically removed. Smaller portions of food make patients feel fuller since the residual stomach is much smaller and less prone to expand to accommodate large meals. Over time, this promotes weight loss by influencing the eating patterns of the patients.

Less ghrelin, the “hunger” hormone, is produced by the stomach when a portion of it is eliminated. Additionally, patients have higher levels of the hormones glucagon-like peptide 1 (GLP-1) and peptide YY (PYY), which reduce hunger and promote feelings of fullness. Patients feel less hungry and are more content with their meals when they have higher levels of GLP-1 and PYY and lower levels of ghrelin. As a result, they eat less.

However, it is possible for patients to gain weight following the treatment, so it is crucial that they exercise, eat a nutritious diet, and refrain from specific behaviors including binge-eating, eating all day, and eating only when they are full.

Why Sleeve Gastrectomy Required?

Sleeve gastrectomy is a procedure used to help you shed extra weight and lower your chance of developing potentially fatal weight-related health issues, such as:

• Heart disease.
• High blood pressure.
• High cholesterol.
• Obstructive sleep apnea.
• Type 2 diabetes.
• Stroke.
• Cancer.
• Infertility.

Sleeve gastrectomy is usually reserved for those who have attempted weight loss through better exercise and diet.

Generally speaking, sleeve gastrectomy surgery might be a possibility for you if:

• Extreme obesity is defined as having a body mass index (BMI) of 40 or above.
• Type 2 diabetes, hypertension, or severe sleep apnea are among the major weight-related health issues you have, and your BMI is between 35 and 39.9 (obesity). If your BMI is between 30 and 34 and you have significant weight-related health issues, you might be eligible for some types of weight-loss surgery.

A healthier lifestyle also requires you to be prepared to make long-term adjustments. Participation in long-term follow-up programs that track your medical issues, lifestyle and behavior, and diet may be mandatory.

A gastric sleeve: what is it used for?

You can limit how much food you can eat in one sitting and feel fuller more quickly by simply shrinking your stomach. It also lowers the quantity of hunger hormones your stomach can create, which is another benefit. This helps reduce cravings and hunger, and it may help avoid the impulsive behaviors that lead to weight loss.

How frequently does gastric sleeve surgery occur?

The most popular weight loss procedure in the US and around the world is the gastric sleeve. Sleeve gastrectomies account for more than half of all bariatric procedures held in the United States annually. In the United States, approximately 150,000 gastric sleeve procedures are carried out annually, while 380,000 are carried out globally. Only 1% of those who would be eligible for the procedure and who could benefit from it, however, actually get it.

Which medical issues are treated with gastric sleeve surgery?

Surgery for obesity and obesity-related disorders is known as gastric sleeve surgery. It is only available to eligible individuals who are at high risk of acquiring major medical issues linked to their obesity. Diseases that can be improved and occasionally cured with gastric sleeve surgery include:

• both Type 2 diabetes and insulin resistance.
• high blood pressure and hypertensive heart disease.
• High cholesterol, or hyperlipidemia, and artery disease.
• This includes steatohepatitis and nonalcoholic fatty liver disease.
• Obesity hypoventilation syndrome with obstructive sleep apnea symptoms.
• osteoarthritis and joint discomfort.

The gastric sleeve: is it safe?

Obesity and its associated conditions carry significantly more dangers than gastric sleeve surgery. Additionally, it has less complications than other common surgeries like hip replacement and gallbladder surgery. Because minimally invasive surgical techniques are used for the majority of gastric sleeve treatments, patients experience less pain from incisions and recover more quickly.

What advantages does surgery for gastric sleeves offer?

A gastric bypass, another kind of bariatric surgery, is more likely to cause problems than a sleeve gastrectomy. Depending on your medical history and desired weight loss, a different kind of bariatric surgery may be suggested.

Having gastric sleeve surgery and losing weight can help:

• manage type 2 diabetes.
• reduce blood pressure.
• strengthen the heart
• increase your standard of living

The Advantages of Gastric Sleeve Surgery for Losing Weight

The bariatric surgeon will remove up to 80% of your stomach during a vertical sleeve gastrectomy and shape the remaining portion into a sleeve-like tube.

The amount of food and liquids you can consume is initially limited to approximately half a cup at a time due to your much smaller stomach. Additionally, your smaller stomach generates fewer hormones that influence your appetite. Significant weight reduction occurs when one wants to eat less and is able to eat less.

Laparoscopic Sleeve Gastrectomy

The majority of the time, your surgeon will make tiny incisions in your belly where tools, such as a video camera, are passed to view the area and carry out the treatment. Robot-assisted surgery and magnets are two examples of tools that surgeons may utilize to improve their surgical accuracy and flexibility. This method to minimally invasive surgery:

• reduces your hospital stay, which is usually only one night.
• causes minor scarring
• helps you heal more quickly and with less discomfort.

How Much Time Will It Take?

The patient’s condition will determine how long the procedure takes, but a sleeve gastrectomy typically takes one to two hours.

Is surgery for gastric sleeves superior to other options for treatment?

Compared to other bariatric surgery procedures, gastric sleeve surgery is less complicated. It doesn’t introduce a foreign item into the abdominal cavity, unlike gastric banding, which employs an inflatable silicone device placed around the upper part of the stomach, and it alters the patient’s anatomy less than gastric bypass surgery.

Sleeve gastrectomy is almost as good as gastric bypass surgery at helping people control their metabolic syndrome or diabetes and lose weight. With gastric bypass surgery, however, patients typically lose a greater percentage of their extra body weight.

The risk of developing gastroesophageal reflux disease (GERD), also known as chronic acid reflux, is higher for patients who have a sleeve gastrectomy than for those who have other bariatric procedures.

Various Surgical Techniques

• Typically, the gastric sleeve procedure is performed laparoscopically with minimally invasive methods.
• Metabolic and Bariatric Surgery Society of America. Methods of Bariatric Surgery.

A less frequent procedure is an open one, in which the stomach is accessed by the surgeon making a big incision in the patient’s belly.

In contrast to gastric bypass surgery, another common weight loss technique, gastric sleeve surgery is technically simpler and carries fewer hazards. Additionally, patients do not view gastric sleeve surgery as excessive because it is merely a restrictive technique that does not limit the small intestine’s ability to absorb nutrients.

What dangers come with having gastric sleeve surgery?

Any operation could result in consequences such as bleeding, infection, heart issues, lung issues, pain, and blood clots in your legs. Breathing issues or other side effects are also possible with general anesthesia. Additionally, there is a chance that the staple line will leak. Additionally, excessive weight reduction may result in sagging skin. Often, both problems require additional surgery.

Some nutrients may also become difficult for you to absorb with time. Or you can experience a constriction or narrowing of the stomach sleeve. Some patients may experience reflux or heartburn following surgery. Additionally, a gastric sleeve may exacerbate moderate to severe reflux. An alternative procedure you might want to think about is a gastric bypass. Surgery of that kind can help prevent or even reverse heartburn and reflux.

Your health may expose you to further hazards. Prior to surgery, discuss any worries you may have with your medical team.

What preparations should I do for gastric sleeve surgery?

It is the responsibility of your healthcare team to determine whether gastric sleeve surgery is a good fit for you. Individuals who abuse drugs or alcohol, or who are unable to make a permanent adjustment in their eating and exercise habits, are not recommended candidates for weight-loss surgery.

You will need to sign up for a bariatric surgery education program prior to surgery. You will be better prepared for surgery and for life after surgery if you do this. You’ll receive dietary advice. You might also be evaluated psychologically. A chest X-ray, blood tests, and an electrocardiogram are among the medical examinations and tests you will also require. To get a better look at your digestive tract, you might have an upper endoscopy or stomach imaging tests.

A few months before to surgery, you will need to quit smoking. Before surgery, you could be asked to lose a few pounds by your surgeon. To lower the chance of problems from surgery, this is crucial. In the days prior to your operation, you will need to cease taking blood thinners such as ibuprofen and aspirin. During your procedure, find out from your healthcare providers which medications, supplements, or herbs should be discontinued (and when) and which should be continued. Before your procedure, abide by any instructions to avoid eating or drinking.

What is the course of gastric sleeve surgery?

Your surgery will be performed under general anesthesia. As a result, you will be extremely sedated during the procedure. Typically, your surgeon will perform the surgery using laparoscopy. Several tiny incisions will be made in your upper abdomen. Small surgical instruments and a tiny tube (laparoscope) will then be inserted into these incisions by the surgeon. An open incision may be required if the laparoscope is not a safe way to perform the procedure.

A little tube will then be passed by the anesthesiologist through your mouth and into your stomach. After dividing the stomach with a laparoscopic stapler, the surgeon will leave a vertical sleeve that is constricted. After that, surgical incision is made to remove the removed stomach portion from the abdomen. A dye study or an upper endoscopy may then be used by your surgeon to check for any sleeve leaks.

After gastric sleeve surgery, what happens?

After surgery, you should be able to return home in one to two days. For the first week or two, you will only be eating liquids. Over the next weeks, you will get a meal plan from your surgical team. After liquids, you’ll go on to pureed foods, soft foods, and finally ordinary meals. Every meal must be really tiny. You should chew each bite thoroughly and consume slowly. Don’t switch to regular food too soon. Pain and vomiting may result from this. Determine what is best for you to eat in collaboration with your healthcare team. Your eating habits will need to change after your stomach heals. You must consume tiny meals for your small stomach.

Patients who undergo weight-loss surgery may experience vitamin and mineral deficiencies. This is because they may absorb less nutrients as a result of eating less. In addition to a calcium-vitamin D supplement, you might need to take a daily multivitamin. Other nutrients, including vitamin B-12 or iron, might be necessary. Instructions will be given to you by your healthcare team.

Following surgery, routine blood tests will be required every few months for the remainder of the year. This is to check for blood iron deficiency (anemia), hyperglycemia, and low levels of calcium or vitamin D. Your stomach acid may need to be reduced by medication if you have heartburn.

Regaining some of the weight you lost is a possibility after losing weight. Follow a nutritious diet and undertake regular exercise to avoid this. Gradually, the sleeve may dilate. That way you can eat more. Remember, though, that you can gain weight if you overeat. Joining a support group for weight loss surgery could help you maintain your new eating routine. To obtain a list of trustworthy resources, ask your healthcare professional.

Risks of Gastric Sleeve Complications

When carried out by a skilled surgeon, problems and fatalities are uncommon after a gastric sleeve treatment. These issues could arise.

Not Losing Weight and Gaining It Back

The reason for this could be that lifestyle choices don’t change or the stomach pouch is excessively big. You may also be able to eat more food because the pouch might expand over time, which may cause your weight reduction to halt and your weight gain to begin.

Ineffective in Treating Type 2 Diabetes

The duodenal switch or gastric bypass surgery are more effective than gastric sleeves.

It Cannot Be Reversed

You cannot undo the removal of a significant piece of your stomach.

Minimal Leaks in the Stomach

In rare instances, leaks may appear years after surgery, although they can also happen soon after.

Internal Hernias and Ulcers Could Develop

It’s less risky than a gastric bypass.

GERD or Acid Reflux Are Frequent

Often, these problems call for medicine.

Insufficient nourishment

might be the outcome of the sharp decline in food consumption. Dietary changes and nutritional supplements may help with this.

Constipation

can result in stomach discomfort, but it can be managed with a stool softener.

What distinguishes sleeve gastrectomy from gastric bypass surgery?

In theory, the gastric bypass is more complicated than the sleeve. To aid with weight loss, the stomach is shrunk rather than the small intestine and stomach being rearranged as is done with a gastric bypass.

To what extent is sleeve gastrectomy surgery effective?

Patients who have the sleeve operation and adhere to the other program requirements usually see weight loss of up to 65%. Many obesity-related problems are also improved or eliminated by them, including:

• Diabetes
• High blood pressure
• Sleep apnea

Most of them can successfully maintain at least 50% of their excess body weight over time.

After a sleeve gastrectomy, would my diet need to change?

Yes, definitely! The pre-operative education that patients get may be even more significant than the actual procedure. We make an effort to educate our patients about eating well. We want everybody to know what a gram of fat, protein, and carbohydrate is and how we should consume them. We are aware that the patient will lose weight more quickly than a typical person for a limited period of time.

Once the body has adapted to the procedure, the patient will be able to continue this weight loss with the support of sustainable, healthful eating habits.

Long-Term Care

Following gastric sleeve surgery, the great majority of patients experience a noticeable reduction in weight. Retaining the weight is crucial. Thankfully, studies show that the average patient loses over 60% of their excess body weight a year after surgery.

Nevertheless, some individuals may need revision surgery due to inadequate weight reduction or weight increase (typically a revision sleeve gastrectomy or conversion to a Roux-en-Y gastric bypass). Another reason for revision surgery is when severe GERD develops after gastric sleeve surgery.

Ultimately, gastric sleeve surgery is not a weight-loss miracle. Following surgery, patients are required to closely follow a diet and activity plan and undergo routine check-ups with their surgeon and a bariatric registered dietician.

Included in this program are:

• Maintaining an eating regimen high in fruits, vegetables, and protein
• Cutting back on snacks, desserts, and processed foods
• Regular exercise
• Monitoring daily food consumption with a food journal or online diary
• Calcium, vitamin D, iron, vitamin C, vitamin B12, and a complete multivitamin are among the vitamins being taken.

Remember that there might be serious emotional problems associated with any kind of weight loss process.

It might be difficult for those who eat as a coping strategy to discover a new way to adjust and handle stress without food.

It’s critical to find constructive ways to deal with stress, like working out or setting aside time for yourself. In addition to a bariatric support group, open and honest conversation with friends and family can be helpful. Seeing a psychologist or therapist who specializes in bariatric surgery may be necessary in certain situations.

Is it successful?

Weight loss is facilitated by gastric sleeve surgery in two ways:

• Because your stomach is much smaller, you feel satisfied and eat less quickly. This implies that you consume fewer calories.
• Because the area of your stomach that makes the hunger-inducing hormone ghrelin has been eliminated, you don’t feel as hungry.

The American Society of Metabolic and Bariatric Surgery states that within the 18 to 24 months after gastric sleeve surgery, you should lose at least 50% of your extra weight. 60 to 70 percent is lost by certain persons.

You must be dedicated to adhering to the diet and fitness regimen that your surgeon has prescribed if you want this to occur. Making these lifestyle adjustments increases your chances of maintaining your weight loss over time.

Other concerns

Another frequent worry is the significant quantity of extra skin you might have left over when the weight drops, particularly if you lose a lot of weight fast. This is a typical consequence of gastric sleeve surgery.

If you are bothered by this extra skin, it can be surgically removed. However, bear in mind that after gastric sleeve surgery, it may take up to 18 months for your body to stabilize. For this reason, it’s usually better to put off thinking about getting your skin removed. Until then, you might wish to attempt some loose skin tightening procedures.

Before choosing to have gastric sleeve surgery, you should also take into account the fact that it is irreversible, in contrast to certain other bariatric procedures. It is impossible to restore your stomach to its previous state if you are unhappy with the result.

Foods and Avoidances on the Gastric Sleeve Diet

A gastric sleeve operation reduces the stomach’s size surgically. After this procedure, people feel fuller more quickly, which drastically lowers overeating.

The size of a person’s stomach is around 25% of its initial size following surgery. A rigorous diet that enables the body to heal and adapt to a lower stomach capacity must be followed.

The best way to get a customized meal plan after gastric sleeve surgery is to speak with a physician or nutritionist. The procedure will need the patient to eat more frequently and in smaller portions for the remainder of their life.

What are the fundamentals?

A surgeon doing gastric sleeve surgery removes a large portion of the stomach to make it resemble a sleeve.

The procedure, which is irreversible, can assist patients in losing a significant amount of body weight.

After a gastric sleeve treatment, people typically lose 90 pounds, according to study from the National Institute of Diabetes and Digestive and Kidney Diseases.

Additionally, the process lessens the body’s production of ghrelin, a hormone that stimulates hunger.

Following surgery, patients typically experience less hunger pangs due to the hormone’s decreased level.

The multiphase gastric sleeve diet was created by specialists to help patients get ready for surgery, rehabilitate, and make the shift to a lifetime of healthy eating easier.

Nutrient deficits may result with gastric sleeve surgery, according to a 2017 study.

Individuals who are worried about gastric sleeve surgery may choose to try natural weight loss by eating only healthy foods and reducing portion sizes.

Phases

Following bariatric surgery, patients must gradually resume eating solid foods. The body can adjust to the new stomach size by doing this.

Typically, after surgery, a physician or nutritionist will monitor a patient’s food consumption. Numerous variables, such as the degree of the surgery and the patient’s level of tolerance, will affect how the food plan is structured.

For a healthy recovery, a certain diet is necessary both before and after surgery.

Presurgery

Frequently, doctors advise a weight-loss plan prior to gastric sleeve surgery.

In a large-scale study published in 2015, individuals who dropped 9.5% of their body weight before to bariatric surgery had a considerably lower risk of all postoperative problems among those whose body mass index (BMI) was in the highest range in the study.

Regarding the duration of a food plan before to surgery, experts cannot agree. But according to a number of studies, a presurgical diet plan that is low in carbohydrates is more beneficial than one that is low in fat for short-term weight loss, particularly for those who have metabolic syndrome or nonalcoholic fatty liver disease.

Physicians advise patients to follow a preoperative diet for two to six weeks in order to decrease the liver’s volume and the quantity of fat surrounding the organs.

A preoperative diet before bariatric surgery has obvious short-term benefits, but further study is required to demonstrate the long-term consequences.

Suggested diets

Not only should a patient alter their diet after gastric sleeve surgery, but they need also alter their eating habits.

It will be necessary for patients to change their dietary habits in order to lower the risk of problems following surgery. Adjustments that are suggested include:

• eating four to six smaller meals daily as opposed to three large ones.
• eating slowly and completely
• finishing a meal when you’re satisfied
• deciding on well-balanced, high-protein meals
• Avoiding food because you’re stressed or bored could helpReliable Source: The procedure’s long-term, beneficial effects
• consuming dietary supplements, maybe permanently, as a result of consuming less protein and other nutrients
• consuming at least 1.5 liters of liquid each day
• avoiding liquids for 15 to 30 minutes after eating because this can cause vomiting

Avoidable foods

A person’s risk of complications following bariatric operations, such as gastric sleeve surgery, is increased by certain diets. People should therefore cut out specific foods and beverages from their diet in order to lower the likelihood of an unfavorable outcome.

These foods and beverages consist of:

• Dry and hard foods that can be challenging for a patient to swallow after surgery
• items high in calories, such cakes, ice cream, milkshakes, and chocolate
• soda and other carbonated and sugar-sweetened beverages
• Items like bread, rice, and potatoes that have a high glycemic index can raise blood sugar levels quickly.
• Gum chewing and meals like beans that cause flatulence are

Recovery and Outlook

After gastric sleeve surgery, how long does it take to recover?

A good month should pass before you expect to feel completely normal or be able to resume your full workload. As their systems adjust to consuming less calories and recuperating, many people experience lethargy or exhaustion during this time. Only a liquid diet will be acceptable to you during the first few weeks. A soft diet will be gradually introduced over time, followed by solid foods.

How much weight would the gastric sleeve help you lose?

It is typical to lose between 25% and 30% of your body weight in the first year or two. In other words, you would drop 100 pounds if you weighed 300 pounds before surgery. Depending on the lifestyle choices you make following surgery, you may lose more or less. Over the course of five years, the average weight loss of 25% to 30% of body weight remains constant, while some people do gain some weight back.

What if it fails?

Although it is uncommon, some people do end up gaining the weight they lost. Over time, they can revert to their previous behaviors or have stomach distension. You may want to think about gastric sleeve revision surgery if this occurs to you. The initial gastric sleeve may be repaired by your surgeon, or it may be replaced with a more effective weight-loss procedure like a duodenal switch or gastric bypass.

Summary

Up to 80% of the stomach may be removed with gastric sleeve surgery, a significant weight loss procedure. In the US, it is among the most popular types of bariatric surgery. Participants will have to sign up for a program that may involve dietary instruction, weight loss, and counseling. People will need to take specific medications and nutrients for the rest of their lives, and recovery could take up to six weeks.

There are various kinds of bariatric surgery alternatives, including gastric sleeve surgery. It reduces the size of your stomach, which allows you to consume less. You’ll notice a decrease in hunger as a result of your stomach getting smaller.

You need to fulfill specific requirements in order to be eligible for gastric sleeve surgery. You must provide evidence that you have tried and failed at other weight-loss strategies, such as diet, exercise, and weight-loss drugs. Your BMI and the presence of any obesity-related medical disorders are additional qualifying factors. After gastric sleeve surgery, you might be able to shed over half of your excess weight in just 24 months if you maintain a regular exercise and nutrition schedule.

However, there is a chance of difficulties and adverse effects, just like with most surgical operations. If you are considering gastric sleeve surgery, discuss with your physician if you are a good candidate for the treatment and whether it is a safe choice for you.

The best time to start exercising again after gastric sleeve surgery should be discussed with a physician. Frequent exercise helps reduce the negative health impacts of obesity and aid in weight loss. A moderate weight can be reached in a year or two following gastric sleeve surgery, while weight loss may be gradual at first. For the best results and the lowest risk of complications, people should gently reintroduce solid foods and modify their eating patterns.
