Gastric Sleeve Outcomes Update 2016

gastric sleeve patient outcomes

It’s a new year which means it is time to evaluate our performance for the previous year, and update our outcomes statistics. This is am important and ongoing part of our practice.

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

The way we know if we are meeting this goal is by very closely tracking our patient outcomes. This is another important and ongoing part of our practice. Dr. Oliak estimates that he has spent over 1000 hours on data entry and data analysis over the past 14 years in his effort to be accountable for his patient outcomes.

In this post we will discuss our 2016 gastric sleeve patient outcomes, and our updated overall gastric sleeve patient outcomes statistics.

Gastric Sleeve Patient Outcomes 2016 – Weight Loss

Through the end of December 2016 Dr. Oliak has completed 375 gastric sleeve operations. Updated weight loss outcomes including the data from 2016 are shown in the table below:

 Percent of Excess Weight Loss (% EWL)
6 months59% EWL
1 year76% EWL
2 years80% EWL
3 years75% EWL

The industry average gastric sleeve weight loss, according to a 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).*

Dr. Oliak attributes his excellent weight loss statistics to quality surgery and quality patient care (education, follow-up, support).

Gastric Sleeve Patient Outcomes 2016 – Leak

This section is easy. Dr. Oliak’s gastric sleeve leak rate was 0% entering 2016, and it remains 0% exiting 2016.**

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. Dr. Oliak attributes his 0% leak rate to good surgical technique.

Gastric Sleeve Patient Outcomes 2016 – 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 who the surgeon is (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 11-15%, depending on how heartburn/acid reflux is defined and how the calculation is done.*

* 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.
