Sleeve Gastrectomy
A sleeve gastrectomy is a type of weight-loss surgery where approximately 75-80% of the stomach is removed, leaving a narrow, sleeve-shaped stomach. This significantly reduces the stomach's capacity, which helps patients feel full more quickly and eat less food.
Procedure Name: Vertical Sleeve Gastrectomy (VSG)
Common Name: Gastric Sleeve Surgery
A gastrectomy is a surgical procedure that involves the permanent removal of a portion or the entirety of the stomach. It is commonly performed on patients with stomach cancer or severe obesity. During the procedure, the surgeon will cut and seal any blood vessels supplying the section of the stomach that will be removed. The remaining part of the stomach is then surgically stapled and sealed, using a calibration guide tube to determine the size of the remaining stomach. Typically, about 80% of the stomach is removed. This operation is classified as restrictive because it limits the amount of food and drink the smaller stomach can hold after the surgery. While a normal stomach can hold up to 2,000 ml, the reduced stomach capacity is less than 150 ml.
DURATION
1-2 hours
ANAESTHETIC
General anaesthesia – discussed with your surgeon
PRE-OPERATIVE CARE
Before your surgery, it is essential to inform the surgeon about any allergies, all medical conditions, and any medications you are taking, including both prescription and non-prescription drugs. If you have hypertension, it is particularly important to notify the surgeon before the procedure to reduce the risk of postoperative bleeding. Additionally, you should avoid any medications containing Aspirin or Brufen for two weeks prior to the surgery.Smoking is also prohibited for two weeks before the surgery. Smoking can affect your reaction to the anaesthetic and slow down the healing process.
POST OPERATIVE CARE
On the first or second day after surgery, you will be encouraged to start drinking water. Once you can drink water without any issues, you will gradually begin your prescribed diet plan. Until you pass this test, you will receive intravenous (IV) fluids to keep you hydrated and prevent dehydration. You will also have a follow-up appointment after you are discharged.
You won't be allowed to eat or drink until you can successfully drink water. During this period, you will receive fluids through an IV drip to stay hydrated. Your mouth may feel very dry, and nurses will provide mouth washes for you to use, allowing you to gargle without swallowing.
Once you can drink water, you will start with small sips, aiming for about 1,200 ml. Initially, you will consume a soft diet during meals. Over the next few weeks, your diet will progress from pureed foods to solid foods. Your meal portions will be much smaller, and you may need to stop drinking liquids with your meals due to your reduced stomach size.
To achieve and maintain weight loss after surgery, significant lifestyle changes are necessary. You will likely need to take vitamins or other supplements for life. Additionally, you will need to increase your physical activity levels. You will not be discharged until you are able to eat and drink adequately.
EXPECTED WEIGHT LOSS &
BENEFITS
Sleeve gastrectomy surgery can help you lose 30-50% of your original weight. This weight loss can alleviate symptoms like fatigue and shortness of breath, enhance your energy levels, and improve your ability to walk and exercise, potentially reducing pain in weight-bearing joints and the back. Several medical conditions may also improve, leading to a reduced need for medication, including:
Type 2 diabetes
High blood pressure
Sleep apnea
High cholesterol
Polycystic ovary syndrome
RISKS AND COMPLICATIONS
The primary surgical risk is leakage along the staple line, which occurs in about 1% of cases. However, Dr. Thakoon, a highly recommended surgeon, has achieved a 0% leakage rate in over 400 patients. Dr. Thakoon typically covers the staple line with omentum to minimise this risk. If leakage does occur, it usually happens within the first week after surgery, potentially extending the hospital stay to 2-4 weeks.
Knowing what complications may arise, as well as what can prevent them, will help patients enjoy a positive experience. As with any surgical procedure, eyelid surgery carries its own set of risks and potential complications.
Wound infection | Bleeding | Stomach ulcers | Strictures | Adhesions | Nutritional deficiencies | Less predictable drug and alcohol absorption Depression and maladaptive eating (uncommon) | Weight gain and recurrence of obesity-related illnesses
It's crucial to follow your surgeon's post-operative instructions carefully to minimise the risk of complications and ensure the best possible outcome.
IMPORTANT
Every surgical or invasive procedure comes with risks. It's advisable to seek a second opinion from a qualified healthcare professional before proceeding.
