Robotic Sleeve Gastrectomy

Weight Loss Surgery in Denver

The robotic sleeve gastrectomy is a fast and effective weight loss surgery. This single procedure involves reducing the stomach to about 15% of its original size with minimal risks, making it more suitable for severely obese patients (BMI > 50).

At Colorado Bariatric Surgery Institute in Denver, we offer a reliable stomach sleeve procedure that produces weight loss results similar to the Roux-en-Y gastric bypass. Moreover, it is superior to the laparoscopic adjustable band or lap band to help decrease food consumption. 

So if you’re interested in bariatric surgery, our weight loss experts can meet with you and determine whether this procedure is right for you!

What Is Robotic Sleeve Gastrectomy Surgery?

In a robotic sleeve gastrectomy surgery (also known as gastric sleeve, vertical gastrectomy, restrictive vertical gastroplasty, or vertical sleeve gastrectomy), Dr. Brown divides the stomach vertically using a line of staples. He will then permanently remove a large portion of the stomach and form the remaining portion into a thin banana-like or sleeve-shaped tube. 

Usually done with a minimally invasive (laparoscopic) surgery, this procedure encourages weight loss by restricting the amount of food the body can take in. Moreover, the ghrelin hormone, which is produced by the part of the stomach that’s removed during a sleeve gastrectomy surgery, plays an important role in appetite and hunger. The decreased quantity of ghrelin allows patients to reduce their food intake and lose weight faster than traditional methods like dieting or exercising alone.

A robotic sleeve gastrectomy is usually completed within one to two hours, and patients typically leave the hospital within one or two days. Here’s an example of a narrated procedure by Dr. Brown that shows how this surgery can be done with minimal bleeding and trauma to surrounding tissues.

Expectations Following Robotic Sleeve Gastrectomy

A gastric sleeve patient can expect to lose about 70% of excess weight within one year of the surgery. Weight loss may be dramatic in the first few weeks, then continuing at a steady but slower rate in the following months. 

In addition, about 70% of patients suffering from type 2 diabetes will experience remission, making them no longer dependent on insulin or medication. For those with sleep apnea or hypertension, 60% can expect these comorbidities to go into remission, allowing medications to be eliminated.

Ideal Candidates for Robotic Sleeve Gastrectomy

Robotic gastric sleeve surgery is not ideal for all people who struggle with obesity. Our team is always here to guide you throughout the process. Before a patient is approved for surgery, we have certain criteria that must be fulfilled.


Ideal candidates are people who are:

  • Between the ages of 18 and 65
  • Morbidly obese with a BMI of 40 or higher
  • Obese with a BMI of 35 or higher and have another weight-related condition like diabetes, high cholesterol, sleep apnea, hypertension, or joint pain
  • Unsuccessful after trying multiple diet and exercise programs
  • Non-smokers
  • Dedicated to maintaining the lifestyle and dietary changes that accompany the surgery

Robotic Sleeve Gastrectomy Diet

If you’re excited about your new body after gastric sleeve surgery, then learning how to eat in a whole new way can be challenging. Preparing for post-surgery life may include following strict dieting rules that are geared toward avoiding complications and acquiring new healthy eating habits. This is so it would be possible to lose weight long term without gaining the weight back.


Pre-gastric sleeve diet


In order to prepare for your procedure, you’ll be given a strict diet that reduces both calories and carbohydrates two weeks prior to your scheduled surgery. You will primarily eat lean protein along with vegetables and low- or no-calorie fluids throughout the day. 

Two days before the procedure, your food will switch to a clear, liquid diet. In addition to water, broth, and decaf coffee and tea, you may also intake one protein shake daily without sugar. Caffeinated and carbonated drinks should be avoided as well.

The main goal of this diet is to shrink your liver, which lies next to the stomach. This makes the procedure easier and safer for you.


Post-gastric sleeve diet


Following the sleeve gastrectomy procedure, you will have to stay on a clear liquid diet for two weeks to avoid bowel postoperative complications such as dehydration, obstruction, gastric leakage, diarrhea, and constipation.

You may start adding soft, low-fat, and sugar-free pureed foods to your diet in the third week. It’s essential to increase your protein intake during this week while making sure to eat slowly.

A month after the surgery, you may start eating solid foods again. Sugar, high-fat, and hard-to-digest food should still be avoided while caffeinated drinks may be taken in moderation. Introduce one food at a time and monitor how your body will react to it. Keep including lean protein and vegetables in your diet as well as being hydrated at all times.
