Premier Orange County Weight Loss Surgery Program

Choosing an Orange County weight loss surgeon is an important decision, because quality of care varies between different surgeons, and quality of care has a strong impact on patient outcomes. Some surgeons provide better patient care (surgery, education, follow-up, support) and achieve better weight loss results, and lower complication rates, than other surgeons (outcomes matter).*

Dr. Oliak’s approach has always been to deliver high-quality surgery and patient care (education, follow-up, support) to achieve excellent, industry-leading patient outcomes. Since starting his career in 2002, Dr. Oliak has established a record (>2500 operations) of patient outcomes statistics (weight loss results, complication rates) that ranks among the best in the weight loss surgery field (our outcomes).*.

Dr. Oliak offers no-obligation educational consultations in Brea and Irvine. A no-obligation consultation is a great way for prospective patients to learn more about weight loss surgery and our Orange County weight loss surgery program.

Sleeve Gastrectomy

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 the 3-4 ounce stomach expands to approximately 6-8 ounces.

Compared to gastric bypass, the gastric sleeve operation is similarly effective for weight loss, but is less invasive and lower risk. These advantages are why more than 70% of all first time weight loss operations in the United States are gastric sleeve operations.

It is important to understand that different gastric sleeve surgeons do the gastric sleeve operation in different ways. What you get (e.g. sleeve size, shape, dimensions, volume, hernia repair, etc.) depends on who the surgeon is, and what you get is an important determinant of outcomes – weight loss results, complication risk. Because of this, choice of surgeon is an important decision.

Dr. Oliak performs what he calls the measured gastric sleeve. By using a specific measuring technique, he is able to achieve highly exact and consistent gastric sleeve anatomy (e.g. sleeve dimensions, size, etc.). Importantly, his specific gastric sleeve technique has been validated by his track record of excellent, industry-leading gastric sleeve patient outcomes.*

Gastric Bypass

The gastric bypass operation involves constructing a very small, 1-2 ounce volume stomach pouch from the existing stomach, and connecting this small stomach pouch to the intestine. When food is consumed, it passes through the pouch into the intestine, bypassing the majority of the stomach.

Compared to sleeve gastrectomy, the gastric bypass operation is more established (40+ years), but it is also more invasive and higher risk. Nonetheless, the gastric bypass operation is often the favored operation for patients with diabetes, significant acid reflux, and higher starting body mass index (BMI>50).

Similar to the gastric sleeve operation, the gastric bypass operation is highly surgeon dependent. How the operation is done (e.g. pouch size/dimensions, intestinal connection size/technique, etc.) depends on who the surgeon is, and how the operation is done is an important determinant of patient outcome. Because of this, choice of gastric bypass surgeon is an important decision.

Dr. Oliak’s gastric bypass surgical technique involves constructing a carefully measured pouch and intestinal connection to achieve very consistent and exact gastric bypass anatomy. Importantly, his specific gastric bypass technique has been validated by his long record of excellent, industry-leading gastric bypass patient outcomes.*

Bariatric Revision Surgery

Bariatric revision operations include repairing/redoing an existing weight loss operation, or revising an existing weight loss operation to a different operation.

Gastric bypass revision operations are most commonly done in an effort to achieve a better weight loss outcome. If the existing gastric bypass anatomy is not ideal (e.g. pouch size, intestinal connection size, etc.), the operation can be revised to achieve more ideal and effective anatomy.

Gastric sleeve revision operations are most commonly done to either achieve a better weight loss result, or to resolve acid reflux. If the gastric sleeve is too large, or shaped poorly, or a hiatal hernia is present, poor weight loss and acid reflux can result. These issues can be addressed by redoing the gastric sleeve to achieve more ideal anatomy. Alternatively, the operation can be revised to a gastric bypass operation.

Gastric banding (LAP-BAND) revision operations are commonly done to achieve a better weight loss result, or to resolve issues such as slip, erosion, vomiting, and esophageal problems (heartburn, reflux). Typically, gastric banding revision involves band removal and conversion to either gastric sleeve or gastric bypass.

Bariatric revision operations are higher risk and more challenging than first time bariatric operations. Choice of bariatric surgeon is particularly important for bariatric revision operations.
