Sleeve Gastrectomy – Bariatric Surgery
Sleeve Gastrectomy – Bariatric Surgery
The sleeve gastrectomy (also called a vertical sleeve gastrectomy) is a type of weight-loss surgery that involves separating part of the stomach and removing it. Although about 75% of the stomach is cut out, gastrointestinal function is preserved and there are few restrictions on what the patient can eat. This procedure facilitates weight loss because the stomach is now much smaller and cannot hold as much food. Additionally, the stomach produces less of the body’s appetite regulating hormones, diminishing the desire to eat.
At The Bariatric and Metabolic Surgery Unit at Sheba Medical Center in Israel, we have a highly trained and experienced team of specialists. Gastrointestinal surgeons, dietitians, and other physicians collaborate to custom-design each patient’s treatment and provide supportive guidance throughout all stages of the sleeve gastrectomy procedure.
How does the sleeve gastrectomy work?
Unlike other bariatric surgeries, the sleeve gastrectomy does not implant any foreign body into your abdomen or rearrange the intestines. Typically, this surgical procedure will be performed laparoscopically and under general anesthesia. It takes about one to two hours, and the procedure is irreversible.
Your surgeon will begin by making a few small incisions in your abdomen in order to insert a laparoscope, which is a narrow instrument with a tiny camera that sends images to a monitor. Using these images as a guide, the surgeon will use other surgical instruments to remove a large portion of your stomach. Your remaining stomach will then be shaped into a tube-like structure (about the size of a banana).
On the first day after your surgery, you will only be able to consume clear liquids. Once you leave the hospital, usually two to four days later, you will be able to eat a diet of soft pureed foods and liquids, such as protein shakes. Most of the time, regular food can be eaten after six weeks (in much smaller quantities than before), and you will need to take nutritional supplements for the rest of your life. After a complete recovery, most patients find that they can comfortably eat a wide variety of foods, including fibrous vegetables and meat.
Along with reducing the size of your stomach so you cannot eat as much, the smaller stomach created by the sleeve gastrectomy also produces less ghrelin, a hormone that helps to regulate your appetite. This may work as an appetite suppressant that boosts the success of your weight loss. In general, people lose about 60% of their extra weight within 12-18 months, especially when eating right and exercising, too.
What conditions can be treated with the sleeve gastrectomy?
The sleeve gastrectomy is intended as a treatment for severe obesity, particularly for people who have not been successful with long-term weight loss using other methods.
What are the possible side effects?
Sleeve gastrectomy is a major surgery, and every major surgery poses some potential health risks. The general complication rate of the sleeve gastrectomy is about 10% – 12%, and the rate of serious complications is less than 3%. Some side effects associated with the procedure are:
- Injury to other organs
- Leaking from the staple line used to divide the stomach (rare)
- Pulmonary embolism
- Kidney stones
- Gastrointestinal reflux
- Gastrointestinal obstructions
Immediately after the surgery, you may experience constipation, nausea, or vomiting, but these symptoms are typically short-lived. Also, you may find that certain foods no longer agree with you.
Who is a candidate for this surgery?
Not all overweight people are good candidates for this surgery, and there are some criteria that must be met before Sheba’s doctors approve a patient for the sleeve gastrectomy.
We generally perform this procedure for people who have been diagnosed with morbid obesity with a BMI (body mass index) over 40, or people who have a BMI over 35 and an obesity-related health condition. In addition, patients must be 18 years of age and older, have a history of failed weight loss attempts, and be committed to making significant diet and lifestyle changes.
Anyone who has a health complication that compromises their ability to handle the stress of the surgery is not a good candidate for the sleeve gastrectomy.
