Sleeve Gastrectomy: Procedure, Recovery, Cost, Risk & Complication

Sleeve gastrectomy is a modern type of weight-loss surgery that involves removing fairly a large portion of the stomach, eventually restricting the amount of food that can be consumed after the surgery. Like every other metabolic surgery, it promotes weight loss by changing the hormonal signals between your stomach, brain and liver.

In this surgery, most of the stomach is removed, leaving a small sleeve-shaped pouch. The patient will not be able to have as much food as he/she was eating previously, so fewer calories will be absorbed in the body, resulting in changes in the hormonal signal that is sent between the brain and the stomach. Therefore, there will be an improvement in the metabolic syndrome, cause weight loss and also maintain overall health and well-being.

Indication

Sleeve gastrectomy is recommended in the following conditions:

  • If a person is very obese and unable to lose weight through dieting or exercising
  • A person who has a BMI (Body Mass Index) of 40 or more than that, meaning almost 100 pounds over the recommended weight. A normal BMI lies between 18.5 and 25.
  • A high BMI along with a severe health condition like heart disease, type 2 diabetes or obstructive sleep apnea. These conditions may improve if extra weight is lost.
  • In some cases, it is done on patients who are too heavy to undergo any other surgery for weight-loss safely

Pre Procedure

There are certain pre-procedure guidelines that you need to follow before undergoing a sleeve gastrectomy:

  • Have a detailed discussion with your doctor regarding the whole procedure; what can you expect post-surgery and the complications that may arise
  • You will have to undergo a complete physical examination and nutritional counselling
  • You also have to go for a blood test, ultrasound test of the gallbladder, along with other tests so that your doctor can ensure that you are healthy enough for undergoing the surgery
  • Inform your doctor regarding any medical conditions that you have, such as diabetes, heart/lung problems or high blood pressure so that they can be kept under control. Also, inform your doctor if you think you are pregnant.
  • Stop smoking.
  • You have to stop eating or drinking anything a few hours before the surgery. Follow the instructions carefully as provided by your doctor.

During Procedure

This surgery is performed by administering general anaesthesia to the patient. A tiny camera will be placed inside the stomach, through one of the small incisions that the surgeon makes on your belly. The camera and the other instruments that are required for performing the surgery are inserted through these tiny incisions. The camera, being connected to a monitor outside, allows the surgeon to have a view of the stomach while he is performing the surgery.

The surgeon will remove most of the stomach, and join the portions that remain with the help of surgical staples. It will change the shape of the stomach like a long, vertical tube, similar to that of a banana. The procedure does not cut or change the sphincter muscles that are responsible for allowing food to enter/leave the stomach. The camera and the other instruments are then removed and the cuts are stitched and bandaged.

Post Procedure

You may have to stay in the hospital for 2-3 days after the surgery. In the first two days, your diet will consist only of clear liquids. After that, you can go on a pureed diet. You will be given medications that will provide you relief from the pain. This surgery will bring about a great change in your lifestyle. Very small amounts of food will fill your stomach quickly. You have to eat healthy foods, control the portion sizes that you eat regularly and exercise on a daily basis. Follow the diet that your surgeon or dietician has recommended.

You will have to visit your doctor 2-3 weeks after the surgery. The wounds will be assessed and if you have any other issues, they will be discussed in this appointment.

Risk & Complication

The possible risks or complications that may be associated with sleeve gastrectomy are:

  • Bleeding or infection from the incision site
  • Formation of blood clots
  • Problems in breathing
  • Injury in the stomach, intestine or other organs in the course of the surgery
  • Inflammation of the stomach lining, stomach ulcer or heartburn
  • Leakage from the area where the parts of the stomach has been stapled together
  • Scarring in the insides of the belly, that could eventually lead to blockage in bowel in the future
  • Vomiting, if you eat more than your reduced stomach can hold
  • Dumping syndrome, when food moves from the stomach to the small bowel at a very fast speed

More Info

It is very important that you monitor your diet eat carefully after undergoing a sleeve gastrectomy. Make sure that you are eating the right foods at the right time, and also prepared in the right way. Foods that can be chewed and swallowed easily must be included in your diet. There are some foods like popcorn, nuts, seeds or hard meat that are not chewed properly before swallowing; hence it is advisable to avoid them. Also, avoid having carbonated beverages that may produce gas due to the digestive enzymes. There is not much room for the expansion of gas in the reduced size of the stomach. Apart from that, exercising is also an important aspect that has to be included in your daily schedule.

The cost of sleeve gastrectomy could be around Rs. 2,50,000 – Rs. 5,00,000.

Bariatric Weight Loss Surgery - How Laparoscopy Can Help In It?
Obesity is a serious lifestyle disorder that can trigger a myriad of health complications. You may often come across people who fail to lose an inch even after toiling hard. The situation may be further complicated and life-threatening if a person is suffering from diabetes, hypertension, arthritis or a heart problem. Bariatric Surgery comes as a much-needed relief for people who desperately need to lose weight to prevent health problems. People between 18-65 years of age can go for a Bariatric weight loss surgery. The surgery is also helpful for people with morbid obesity (a condition where the BMI is over 40) with associated complications. Some of the effective bariatric surgeries for weight loss include Laparoscopic Gastric Band surgery Roux-en-Y Gastric Bypass Surgery (RGB) Laparoscopic Sleeve Gastrectomy Biliopancreatic Diversion Common types of Bariatric surgeries The Laparoscopic Gastric Banding: The gastric banding surgery is a surgical weight loss procedure that divides the stomach into two compartments so that a person consumes lesser amount of food. The surgery requires the surgeon to make 3-4 small cuts in the belly. An adjustable silicone band is placed into the stomach (through the small incisions) to divide the stomach into two compartments (a smaller upper half and a bigger lower part). Due to the banding, the stomach can hold not more than an ounce of food, thus limiting the amount of food a person can eat. There is an opening in the band which serves as a passage through which the food eaten is passed to the rest of the stomach. There is a plastic tube that connects the band to an injection port (situated under the skin). It is through this port that saline is either added or removed from the silicone band (to adjust the tightness of the band). Roux-en-Y Gastric Bypass Surgery (RGB): The bypass surgery also involves compartmentalizing the stomach into an upper half (small pouch, almost the size of a walnut) and a bigger lower part. Like the gastric banding, the rearrangement reduces the amount of food the stomach can hold to a great extent. In the next step, also termed as the bypass step, the surgeon makes a small hole in the pouch to connect it to the small intestine or the jejunum. As a result of the bypass, the food will now directly enter the small intestine from the pouch. While the bypass surgery can be done using laparoscopy, a person can also undergo an open surgery. Laparoscopic Sleeve Gastrectomy: As the name suggests, the surgery involves excision of a large part of a stomach. The excision leaves behind a small sleeve-like pouch, the arrangement ensuring that a person consumes a lesser amount of food. Biliopancreatic Diversion: The surgery is risky and is advised only when an individual has a BMI of more than 50. In Biliopancreatic Diversion, the surgeon excises a part of the stomach, while connecting the remaining half to the lower part of the small intestine or jejunum. As a result, a person consumes lesser calories than before.

6 Types Of Bariatric Surgery You Can Think of!
Obesity can shorten your lifespan by decades and also limit and reduce the quality of your life. Obesity cannot always be controlled by dieting and exercise and thus more complicated means such as bariatric surgery has to be employed. Types of bariatric surgery Most bariatric surgeries either limit your ability to consume food and thus make you feel fuller quickly or limit the absorption of nutrients from the food you eat. Certain surgeries use a combination of the two in varying degrees. Mentioned below are the most commonly employed forms of bariatric surgery Gastric Balloon This is a form of surgery wherein a specially made balloon is inserted into the stomach. In certain cases even two balloons are inserted into the stomach to reduce the room left for food. This causes you to have less food resulting in weight loss over a period of time. Gastric Sleeve This is a form of surgery wherein a major portion of the stomach is removed through the procedure. Also known as Vertical Sleeve Gastrectomy, the surgeon creates a pouch within the stomach which essentially becomes a connecting tube between the esophagus and the large intestine. The reduced stomach size causes fewer hunger related enzymes and hormones to be secreted, causing less hunger and also reducing your food intake capability. This results in weight loss over a period of time. Gastric Bypass Gastric bypass uses the combination of two techniques, lesser absorption of minerals as well as reduced intake capacity. In this method, a part of the stomach is rearranged akin to the gastric sleeve. However the leftover portion of the stomach is not removed as it can continue to secrete stomach acids. Because of the reduced size of the stomach, you would eat less and if you happen to over eat, it would cause dumping syndrome (quick and repeated bowel evacuation) which would deter you from eating more. Lap band surgery This is one form of surgery where the stomach is not reduced or cut but rather limited by a band that is put around it. This band constricts the stomach and causes the upper part to become smaller. Hence you would feel fuller from eating less, thus resulting in weight loss. V-bloc therapy This is a very modern approach to bariatric procedures which works in a very similar way to a pacemaker. A device is placed just under your skin and two leads or wires are connected to the vagal nerve. This nerve is responsible for sending the hunger signals to the brain from the stomach. This device acts as a block to the nerve signals and thus ensures you eat less. Duodenal switch This surgery is also known as a Biliopancreatic Diversion wherein the surgeons cut out the part of the stomach similar to a gastric sleeve surgery but also make adjustments to the pancreatic chain and the small intestine to reduce the absorption of minerals.

Bariatric Surgery - Aftercare Tips You Must Follow!
If you have taken the big decision to go ahead with bariatric surgery, one thing you need to prepare for well in advance is the additional effort that is required after the surgery to ensure it is a success. The results will be evident only after a few months post the surgery. This period requires your constant attention. Listed below are some after-care measures that are essential for the success of a bariatric surgery. Hospital stay: Most patients are advised hospital stay for four days, during which the hospital staff will ensure the sleeve is working fine. No food is allowed for 48 hours. Diet is gradually advanced from water to clear liquids, about 50 ml to 100 ml and then to 150 ml. Wound care: Depending on whether a laparoscopic or open surgery was done, the number and location of incisions will vary. However, the wound should be maintained clean and it should be ensured that there is no infection of the site. Wound care should be done by the nursing staff if required. Suture removal, if required, should be done as per doctor s advice. Pain management: Finish the course of antibiotics and pain killers to ensure infection is completely gone. Pain would continue, if the infection is not completely controlled. Diet: The first two weeks would be a completely liquid diet. The next two weeks will consist of a pureed diet. After these four weeks, solid foods will be introduced. Foods to avoid after a bariatric surgery include anything with a higher protein content and anything that has too much oil as the stomach s ability to digest these is reduced. Refrain from: Carbonated beverages Hard meat Nuts and seeds Fried foods Food items to include post bariatric surgery include those which are easy on the stomach, including: Liquids such as soups, broth, juice, and milk Pureed cooked vegetables and eggs Soft mashed food including meat and vegetables Adherence to this will reduce complications. While eating, the patient should also remember to chew nicely, eat and drink slowly, increase water intake throughout the day, and avoid fats and sugar. It is advisable to eat three proper meals a day and avoid snacking during the day. Remember that the need for bariatric surgery arose in the first place due to uncontrolled eating of oily food. After undergoing a bariatric surgery, diet pattern is definitely going to move to a healthier side with reduced fat and sugars. It is not an easy shift, but definitely required, if the surgery is to be a success. Imagine the new you and you will be able to do it!

Weight Loss Surgery - 4 Types That Can Help You Shed Fast!
Obesity is unarguably one of the most regularly discussed topics around the world. A major section of the world's population is suffering from a variety of obesity related problems. There are a number of natural methods to check obesity; however, several medical surgeries are gaining popularity among the masses with instant results to reduce weight. Here is a list of the most common types of weight loss surgeries: 1. Gastric sleeve surgery: This surgery is performed where removal of a large part of the stomach takes place. A long pouch is created, which connects the small intestine with the oesophagus. The pouch gets stapled and after that the other parts of the stomach are reduced. In some cases, an additional step is taken for reinforcement of the staple line. Gastric sleeve reduces the size of the stomach and a patient will feel full after eating lesser amount of food. Because a portion of the stomach is reduced, lesser amount of hunger causing hormones are produced. The patient will therefore feel less hungry. 2. Gastric bypass surgery: This is another effective weight loss surgery, which reduces the patient's stomach size, resulting in reduced appetite. The intestines are rearranged, which makes the body absorb fewer minerals. While performing this surgery, the stomach is cut and stapled to create a pouch. The remaining stomach is attached to the small intestine's top portion, and the small intestine is cut and attached to the pouch as well. After this, the end portion of the small intestine is connected with the non-pouch part of the stomach and is attached to the roux limb bottom. This makes the stomach's digestive juices to meet the food present in the intestines. 3. Duodenal switch: This surgery reduces the stomach size in patients, which leads to decreased appetite or craving for food. Fewer hormones, which cause hunger, are secreted and the rearrangement of the intestine causes the body to absorb minimal minerals or calories. A part of the stomach is removed and a pouch is created. The small intestine's top portion is cut off, but the duodenum is kept attached to the stomach. The small intestines are cut, and the part attached to the large intestine called colon is connected with the duodenum. Finally, the loose end of the small intestine gets attached to the small intestine to enable digestive juices to mix with food. 4. Lap band surgery: By this surgery, a band is wrapped around the upper middle section of the stomach which squeezes the stomach. Thus a smaller section of the stomach is created above the band which fills up very quickly while having food. The patient feels full by eating less. A laparoscopic adjustable gastric band is used. There are many different weight loss surgeries. Most of them aim at reducing the capacity of the stomach, so that the person eats less food.
