How a gastric sleeve is performed?

What is a gastric sleeve?

A gastric sleeve or gastrectomy is performed to remove approximately 75 per cent of your stomach. Your newer, smaller stomach will be about the size of a banana. With this vastly reduced stomach you’ll feel full for longer after smaller portions. Your weight loss is normally fairly rapid,due to a reduced intake of food. The gastric sleeve does not alter your digestive pathway so food follows its normal route.

Who can have a gastric sleeve?

A gastric sleeve procedure may be recommended if you have:

·a body mass index (BMI) of 40 or more.

·a BMI of 35 or more and a serious medical condition that might improve with weight loss, such as obstructive sleep apnoea,type 2 diabetes, and heart disease.

·a gastric sleeve may be appropriate for those with a lower BMI depending on clinical services.

Before the operation

Prior to having a gastric sleeve operation your bariatric surgeon will give you advice on a pre-op diet to prepare your body for surgery.

They will request that you stop smoking, as smoking increases the risk of infections, pneumonia, blood clots, slow healing and other life-threatening complications after surgery.

You may want to talk to family members, friends, or healthcare professionals such as your GP to ensure you’re emotionally ready for gastric sleeve surgery. Life after gastric sleeve surgery can be an emotional roller coaster so you need to be prepared for these ups and downs.

In order for the operation to be successful and for you to reach your weight loss goals you must be able to make major changes to your lifestyle after surgery including keeping to a healthy diet and partaking in regular physical activity.

On the day of surgery, you will be given a general anaesthetic that puts you to sleep so you won’t feel any pain during the operation.

During surgery

Gastric sleeve surgery is normally carried out using keyhole or minimally invasive surgery. This has advantages over open surgery including:a shorter hospital stay, a faster recovery time, reduced pain and bleeding following the procedure and less scarring.

Your bariatric surgeon will make two to five incisions in your stomach. They will insert a laparoscope through these cuts and any tiny instruments they require to perform the surgery.

A laparoscope is a small tube that has a light source and a camera and is connected to a video monitor in the operating room. It relays images of the inside of your stomach to the television monitor so that your surgeon can see what they’re doing during the operation.

Your surgeon will then carefully remove a large part of your stomach. They will then join together the remaining portions of your stomach using surgical staples to create a long sleeve shaped tube that will form your new stomach.

Your bariatric surgeon will then remove the laparoscope and operating tools and stitch the incisions closed.

Typically, gastric sleeve surgery takes between sixty minutes.

After the operation

Following your operation, you will probably stay in hospital for a day or two. Your stomach might be swollen and sore for several days and your surgeon may prescribe pain medication.

You should be able to drink clear liquids on the day after surgery.

Your surgeon will advise you on a post-surgery diet and it’s important that you follow it. Initially you’ll need to become re-accustomed to eating solid foods. Normally this starts with two weeks on a liquid-only diet, followed by two weeks of semi-solid, pureed foods and then solid foods.

Gastric sleeve surgery patients on average lose between 50 to 70 percent of excess body weight in two years. Initially weight loss might be rapid. To ensure the weight continues to come off and you reach your weight loss goals you’ll need to start regular exercise. Weighing less should make it much easier for you to move around, do your everyday activities and take up new past-times. You might choose walking, jogging, cycling, tennis, gym work or swimming. You’re more likely to stick to an activity if you enjoy it. Don’t overdo things to start with, gradually increase the amount of exercise you do.

Losing substantial weight after surgery can improve many medical conditions you might suffer from including: asthma, type 2 diabetes,arthritis, high blood pressure, obstructive sleep apnoea, high cholesterol, and gastroesophageal disease (GERD).

How does a gastric sleeve work?

A gastric sleeve works by the following mechanisms:

1.your new stomach pouch will hold a considerably smaller amount of food than a normal stomach. This helps to significantly reduce the amount of food that you can eat. As you are taking in far less calories, you will lose substantial weight. also removes the portion of the stomach that produces the gut hormone called Ghrelin, also known as the hunger hormone. This greatly reduces your feelings of hunger and causes a reduction in appetite.

Gastric sleeve surgery doesn’t re-route your digestive system (as in a gastric bypass procedure) and doesn’t affect what you can eat or the way your food is absorbed.
