About Gastric Sleeve Surgery

The gastric sleeve operation (also known as sleeve gastrectomy) involves removing a large portion of the stomach, to reduce stomach volume from approximately 30-40 ounces to approximately 3-4 ounces. Over time, sleeve volume increases to approximately 6-8 ounces.
Watch a gastric sleeve operation

The gastric sleeve operation is done laparoscopically, generally using 5 small incisions. The operation typically takes 1-2 hours to complete. Patients are generally discharged from the hospital the next day, and return to work in 1-2 weeks. Recovery is usually rapid because of the minimally invasive, laparoscopic approach.

Patients remain on a liquid diet for 2-3 weeks after surgery, and then slowly transition onto solid foods. Meal portion sizes are typically 2-4 ounces when patients start solid food, and slowly increase in size to approximately 6-8 ounces over the first 1 year.

Why Choose Gastric Sleeve Surgery?

Because the gastric sleeve operation has been proven over 15+ years to be highly effective for weight loss (similar to gastric bypass), because the gastric sleeve operation is less invasive and lower risk than the alternative weight loss operations (gastric bypass, duodenal switch), and because patients love it!*

Gastric sleeve risks

The most compelling reason to choose gastric sleeve surgery, in Dr. Oliak’s view, is its effectiveness for weight loss. The better published studies report that patients lose an average of 60-80% of their excess weight after gastric sleeve surgery.* Long-term studies (>5 years) show that patients, on average, maintain the majority of their initial weight loss.*
Gastric sleeve weight loss

The reason the gastric sleeve operation (and gastric bypass) works so well is because it changes the biology that normally works to block weight loss. The gastric sleeve operation, in effect, “resets” the body weight “set-point” to a lower, healthier weight. This enables not just initial weight loss, but long-term weight maintenance.*
Surgery changes body weight set-point

These characteristics – effective weight loss, lower risk than alternative weight loss operations (e.g. gastric bypass, duodenal switch) – are why the gastric sleeve operation is the most commonly performed operation for weight loss in the United States. Currently, more than 70% of all first time weight loss operations performed in the United States are gastric sleeve operations.

Why Choose Our Orange County Gastric Sleeve Program?

Because we provide a high quality of service, and we have an established record of excellent patient outcomes.*

It is important to understand that gastric sleeve surgery is not a set, standardized thing. Gastric sleeve surgery is a service that includes the performance and details of the operation, and the associated patient care (education, follow-up, support). Quality of service varies over a very wide range, from excellent to poor, between different surgeons and programs.

Quality of service is important because it has a strong impact on patient outcomes – weight loss results, complication rates.* Because surgeon/program outcomes statistics are generally not known by patients, there is often not much surgeon incentive to provide high quality of service.

Dr. Oliak and his Orange County gastric sleeve program are committed to providing a high quality of service, and achieving not just good, but excellent, industry-leading gastric sleeve patient outcomes.

Dr. Oliak’s Gastric Sleeve Surgical Technique

Achieving great outcomes starts with performing great surgery. The challenge of performing a great sleeve gastrectomy operation is the fact that the operation is not standardized, and it is inherently inexact and subjective. If you have 10 different gastric sleeve surgeons, you will get 10 different gastric sleeve operations (learn more).

Dr. Oliak performs what he calls the measured gastric sleeve. He uses a specific measuring technique to construct very exact and consistent gastric sleeves. To watch Dr. Oliak perform and narrate a measured gastric sleeve operation, click here.

The best quality indicator for a surgeon is the surgeon’s record of actual patient outcomes. Orange County gastric sleeve surgeon Dr. Oliak has a record of weight loss statistics and complication statistics, using the measured gastric sleeve technique, that ranks among the best in the weight loss surgery field (learn more).*

Gastric Sleeve Orange County Weight Loss

The sleeve gastrectomy operation has been proven to be an effective operation for weight loss both short-term (1-3 years) and long term (5+ years) after surgery.

The published gastric sleeve literature reports short-term gastric sleeve weight loss to average anywhere from 40-80% excess weight loss, depending on surgeon/program.* Overall industry average gastric sleeve weight loss is reported to be approximately 55-60% excess weight loss.* The long-term (5+ years) gastric sleeve weight loss studies report that patients, on average, maintain the majority of their initial weight loss over time.*
Surgeon outcomes vary

Dr. Oliak’s Orange County gastric sleeve weight loss results are significantly better than the industry average 55-60% excess weight loss.* Dr. Oliak’s patients average approximately 75% excess weight loss at 1-3 years after surgery.* For the average patient (BMI 42), this amounts to about 20 pounds more weight loss than the industry average.*

Sleeve Gastrectomy Orange County Complications

A major advantage of the sleeve gastrectomy operation, compared to the gastric bypass operation, is that it is less invasive and therefore lower risk. This is the #1 reason for why the gastric sleeve operation has become the most commonly performed operation for weight loss in the United States.

Although the gastric sleeve operation is considered low risk, complications can occur. The most feared early complication after gastric sleeve surgery is generally considered to be leak, and the main long-term complication after gastric sleeve surgery is generally considered to be acid reflux.

Like with weight loss results, leak rates and acid reflux rates vary over a wide range between individual surgeons.* Why? Because quality of service varies!

Leak rates for experienced surgeons (rates for less experienced surgeons can be higher) vary from 0% (0 in 500+ operations) to 4% (1 in 25 operations).* Acid reflux rates for surgeons vary from low (<20%) to high (>50%).* Dr. Oliak’s statistics for leak (0%) and for acid reflux (15%) rank among the best in the field.* Quality of service matters!

More About How Sleeve Gastrectomy Works

Sleeve gastrectomy causes weight loss by restricting food intake and by changing the body weight ”set-point” to a lower weight.

Everybody has a “set-point” weight. This is the weight that the body tries to maintain. When a person loses weight to below the set-point, the body responds by increasing hunger, appetite, and cravings, and by decreasing metabolism in an effort to cause weight regain back up to the set-point weight. This biology is what makes losing weight so difficult, and what makes maintaining long-term weight loss virtually impossible.
Body weight set-point blocks weight loss

Unfortunately, these body weight control mechanisms often don’t work with weight gain to above the set-point. Weight gain, instead of leading to less appetite and a higher metabolism, often leads instead to a resetting of the set-point to the higher weight!

Weight loss surgery (gastric sleeve surgery, gastric bypass surgery), we are learning, changes this biology. Weight loss surgery, in effect, resets the body weight set-point to a lower weight. To date, weight loss surgery is the only thing we know of that does this. This is the key reason for why weight loss surgery works so much better than other weight loss methods.*
Weight loss surgery changes set-point

The long-term challenge of weight loss surgery is the fact that surgery does not change the biology of weight gain. Excess calorie intake after surgery can cause weight gain and an increased set-point like it could before surgery. The key to long-term success is establishing good eating and exercise habits to maintain the new, lower set-point weight.
Achieving gastric sleeve success

Gastric Sleeve Orange County – Am I a Candidate?

Gastric sleeve Orange County candidates must be at least 50-100 pounds overweight (BMI 30 or greater), and have tried and failed to lose weight and keep it off.
Calculate body mass index (BMI)
Gastric sleeve for low BMI (30-35) patients

Insurance companies are more restrictive. Candidates generally must have either a BMI of >40, or a BMI of 35-40 with other medical problems such as diabetes, high blood pressure, or sleep apnea. Insurance companies often also have other requirements, such as the completion of a 6-month medically supervised weight loss program prior to surgery.
Payment options

Importantpatients with more severe/chronic heartburn/gerd/hiatal hernia may be better candidates for gastric bypass surgery. Heartburn/gerd is the primary potential long-term issue after gastric sleeve surgery. The chance for hearburn/gerd becoming a problem after surgery is higher in patients with more severe/chronic preoperative heartburn/gerd/hiatal hernia.

* Patient outcomes vary after weight loss surgery. Individual patient results can be better or worse than the average.
