Gastric Sleeve Surgery


What is gastric sleeve surgery?

Nowadays the rate of obesity and its related problems and illnesses are increasing, so the issue of weight loss has become more and more important. Although the best way to lose weight is to have a proper diet and exercise, sometimes the obesity problem is very serious, which is not easily resolvable, and other methods, such as surgery can be considered. Sleeve gastrectomy has become a popular therapeutic approach among patients with obesity who are seeking weight loss. This method reduces the stomach volume so the appetite is reduced and the patient loses weight. This method is usually done based on laparoscopy. But it is generally not recommended to perform gastrectomy as a treatment for obesity unless all other procedures have failed. Sleeve gastrectomy is usually done for many purposes other than obesity. The most important of which is the treatment of some stomach problems that cannot be treated in any other way, as in the following cases:

• The presence of stomach tumors (malignant or benign).

• Bleeding.

• Certain infections.

• There are holes in the stomach wall.

• The presence of strange lumps and appendages inside the stomach.

• Stomach cancer.

• Ulcer acute stomach.

Gastric sleeve surgery pre-operative surgery

The bariatric surgeon may recommend a pre-operative diet before the surgery which has protein but carbohydrates and fat limitations. This diet makes the body ready for the surgery. Patients should tell the surgeon their complete medical history and medicines and supplements intake. The surgeon will also ask for laboratory tests like blood tests and some medical images to check body health completely and to ensure the patient’s readiness for the process and its ability to bear it. It is important to know that patients should try to stop smoking for better outcomes and they should stop smoking at least 30 days before surgery. Smoking increases the hypothetical period that the body needs to recover after the operation, and increases the chances of infection. If the patient is a woman, she must inform the doctor if she is pregnant, intends to become pregnant, or has any diseases such as diabetes.

 Gastric sleeve procedure

There are two different ways to perform gastric sleeve procedure, but both take place with the patient under general anesthesia, and the two methods are: • Regular surgery: This includes making a large incision to reach the stomach. • Laparoscopic surgery: This type of procedure does not require a major incision in the affected person’s body to reach the targeted internal area. This type of surgery is usually preferred over regular surgery to reduce the chances of complications. After reaching the stomach, the surgeon will remove a part of your stomach and usually, a banana-shaped stomach remained. Then the incision is closed with sutures.

Gastric sleeve surgery post-operative surgery

Patients feel pain after the anesthesia is gone, so they need pain killers. After the operation, the doctor puts the patient under the supervision and medical care in the hospital for at least 1-2 weeks. The patient gets food during the recovery period intravenously. On the day after the surgery, the patient can drink liquids and after some days pureed foods can be added to the regimen. This method can be continued for about a month and then they can gradually add solid foods. Often, during a hospital stay, the doctor will connect a special tube between the patient’s nose and stomach, to help the stomach get rid of any fluid that might get stuck in it, and relieve the patient’s feeling of nausea. After the gastric sleeve surgery, it is necessary to change the patient’s life and nutritional habits, and these changes include: • Eat less food at every meal during the day. • Avoid eating foods rich in fiber. • Focus on eating foods rich in calcium, iron, vitamin C, D, B12. • Take a vitamin supplement. • Chew food carefully. • Drink liquids half an hour before meals. The patient may need a relatively long time to recover after performing the gastrectomy, but in the end, the rest of the stomach will expand and the small intestine will expand slightly, at which time the patient will be able to eat more fiber and generally larger meals. Patients can go back to work in 1 to 3 weeks and they should avoid strenuous activity for the first 30 days.
