Dr. Oliak’s Gastric Sleeve Surgery Patient Outcomes – Update 2018

gastric sleeve patient outcomes

Dr. Oliak provides weight loss surgery in Orange County, CA. His #1 goal since starting his weight loss surgery career in 2002 has been to achieve not just good patient outcomes, but excellent, industry-leading patient outcomes.

The fact is, gastric sleeve surgery patient outcomes vary between different surgeons and programs. The reason why is because different surgeons and programs do the gastric sleeve operation in different ways, and do patient care (education, follow-up, support) in different ways. Quality of surgery/patient care has a major impact on patient outcomes.

The way we know if we are meeting our goal of achieving excellent outcomes is by very closely tracking our patient outcomes statistics. Let’s see how we are doing…

Gastric Sleeve Surgery Weight Loss

Our gastric sleeve surgery weight loss statistics, updated through early 2018, are shown in the table below:

 Percent of Excess Weight Loss (% EWL)*
6 months59% EWL
1 year75% EWL
2 years77% EWL
3 years74% EWL
* The weight loss results above are averages. Individual patients can lose more or less weight than the average. Our %EWL (percent excess weight loss) statistics are for all gastric sleeve operations completed through early 2018 (n=423).

The industry average gastric sleeve weight loss, according to a large study by Gagner et al, who analyzed data from a large number of surgeons/operations (130 surgeons, 46,133 gastric sleeve operations), is 55-59% EWL at 1-3 years after surgery (59.3% EWL at 1 year, 59.0% EWL at 2 years, 54.7% at 3 years).*

Our gastric sleeve surgery weight loss results compare favorably to the industry average weight loss statistics quoted in the Gagner study above.

The published literature on gastric sleeve weight loss does show a wide variation in weight loss results between different surgeons and programs. Some surgeons and programs achieve better weight loss results than others.

Gastric Sleeve Leak

This section is easy. Dr. Oliak’s gastric sleeve leak rate is 0%.**

To review, a leak is a hole in the stomach that can develop during healing after gastric sleeve surgery. It is a serious complication that can be life-threatening. Surgeons in general are very focused on trying to prevent leaks.

The industry average leak rate, according to a study by Aurora et al, who compiled data from 29 different published leak studies involving 4,888 gastric sleeve operations, is 2.4%, with a range between surgeons from 0% to 7%.**

Leaks are generally related to surgical technique. The fact that some surgeons have leak rates of 0% suggests that leaks can be largely prevented with good surgical technique.*

Gastric Sleeve Heartburn/Acid Reflux

Heartburn/acid reflux is the main potential long-term issue after gastric sleeve surgery. Published studies suggest that one of the most important determinants of heartburn risk after gastric sleeve surgery is the surgeon (Oor et al).*

The variation in reported heartburn/acid reflux rates after gastric sleeve surgery is likely due to variability in surgeon technique regarding the diagnosis and repair of hiatal hernias, and regarding the surgical details of how the gastric sleeve is constructed.

The incidence of worsened heartburn/acid reflux in our gastric sleeve patients is approximately 15%.*

* Patient results vary after weight loss surgery. The gastric sleeve outcomes quoted on this page are averages – individual patients can do better or worse than the average.

** Leaks can occur after gastric sleeve surgery. Past leak rates may not be indicative of future leak rates.
