About Gastric Sleeve Surgery

Gastric sleeve surgery (also known as sleeve gastrectomy, vertical sleeve gastrectomy, VSG) involves surgically removing a large portion of the stomach, to reduce stomach volume from approximately 30-40 ounces to approximately 3-4 ounces. Over time, the gastric sleeve will expand to approximately 6-8 ounces.

Why Choose Gastric Sleeve Surgery?

Reasons to choose sleeve gastrectomy include the following:

  • Highly effective for weight loss – similar to gastric bypass
  • Established – proven safe/effective over >15 years
  • Minimally invasive – laparoscopic or robotic approach
  • Low risk – less risk than gastric bypass
  • High patient satisfaction – patients love it!

Patients and surgeons commonly choose gastric sleeve surgery over alternative weight loss surgeries such as gastric bypass, gastric banding, and duodenal switch. Currently, 70-75% of all first time weight loss surgeries in the United States are gastric sleeve operations.

Patient Testimonials

Surgeon & Program Outcomes Matter – A Lot!

Gastric sleeve patient outcomes are not uniform between individual surgeons and programs. Some surgeons and programs achieve better weight loss results and lower complication rates than others.

Because outcomes are not uniform, knowing a surgeon’s/program’s record of actual patient outcomes is important to be able to judge surgeon/program quality and performance.

Most surgeons and programs, however, don’t make their outcomes statistics known. This is nice for surgeons and programs (less accountability), but not ideal for patients.

Dr. Oliak has been publishing his outcomes statistics since he started his practice in 2002. For the outcomes that matter most – weight loss, early major complications (e.g. leak), and late complications (e.g. acid reflux) – Dr. Oliak’s statistics beat the industry benchmarks, often by a wide margin.*

Sleeve Gastrectomy Surgery and Recovery

Gastric sleeve surgery involves removing a large portion of the stomach to reduce stomach volume from about 30-40 ounces to approximately 4 ounces. Over time, the small sleeve stomach will expand to approximately 6-8 ounces.

The gastric sleeve operation is done laparoscopically or robotically, generally using 5 small incisions. The operation typically takes 1-2 hours. Patients generally stay in the hospital for 1 day, and return to work in 1-2 weeks.

Gastric sleeve Orange County patients remain on a liquid diet for 2-3 weeks after surgery, and then slowly transition onto solid foods.

Gastric Sleeve Weight Loss

Weight loss after gastric sleeve surgery is generally fast, and occurs over 1-1.5 years.

Gastric sleeve patients lose, according to the better published studies, an average of 60-80% of their excess weight after surgery, and maintain, on average, most of their initial weight loss long-term.*

Sleeve Gastrectomy Surgery Orange County – What Are the Risks?

Sleeve gastrectomy is considered a safe operation, but complications can occur, as they can for any operation.

Early Complications
The two most feared potential early complications after gastric sleeve surgery are bloods clots and leaks. The risk for blood clots and leaks can be minimized with quality surgery and good patient care, but not completely eliminated.*

Late Complications
The primary potential long-term complication after gastric sleeve surgery is heartburn/gerd. When heartburn/gerd does occur after surgery, symptoms generally can be easily controlled with medication. The risk for heartburn/gerd can be minimized with quality surgery, but not completely eliminated.*

Gastric Sleeve Risks

How Does Sleeve Gastrectomy Work?

Sleeve gastrectomy surgery causes weight loss by restricting food intake, and by changing the biology that regulates bodyweight, resulting in a lower bodyweight “set-point.”

This biology change is what makes long-term weight loss possible after surgery.* The reason nonsurgical weight loss methods don’t work long-term is because nonsurgical weight loss methods don’t change the bodyweight set-point.

Surgery Changes Set-Point

The long-term challenge of gastric sleeve surgery is the fact that it does not change the biology of weight gain. Excess calorie intake after surgery can cause weight gain and an increased set-point like it did before surgery.

The key to long-term success after sleeve gastrectomy is establishing good eating and exercise habits to prevent excess calorie intake.
