Robotic “Re-Sleeve” Gastrectomy Houston

Robotic “re-sleeve” gastrectomy is a revision surgery that describes the concept of re-calibrating or re-sleeving the stomach to achieve improved portion control. This surgery is facilitated by the precision of a robotic surgical platform to increase the procedure’s safety and enhance quality outcomes. Sleeve gastrectomy has recently become a very popular procedure for surgical mediated weight loss for patients who are battling obesity. Sleeve gastrectomy tends to have fewer long-term complications as compared to gastric bypass or duodenal switch procedures.

What is Robotically Assisted Gastric Sleeve Revision Surgery?

Currently, many bariatric patients are opting for gastric sleeve surgery to treat their morbid obesity. The procedure has recently emerged as an appealing alternative to gastric bypass surgery because a sleeve gastrectomy is a simpler operation with far less likelihood for long term complications. Despite long-term efficacy, gastric sleeve patients may encounter issues that may need surgical correction. In these instances, Dr. Bonnor may recommend gastric sleeve revision to get your weight loss back on track or correct anatomic issues that may contribute to acid reflux or regurgitation.

At Texas Endosurgery, Dr. R.M. Bonnor specializes in robotic surgery, a platform to enhance techniques in surgery and patient outcomes. In robotic re-sleeve gastrectomy surgery, Dr. Bonnor employs a robotic device to revise a previous sleeve gastrectomy.    

Can You Gain Your Weight Back After Gastric Sleeve?

Patients may stop losing weight or even regain some of their lost weight after a gastric sleeve surgery. Without careful monitoring of their post-operative recovery, some patients may find themselves in need of a gastric sleeve revision.  Patients usually present one year to 18 months after the initial gastric sleeve surgery for consideration or revision.[1] It is during this time when some patients notice changes in portion control or acid reflux not responsive to medical therapy. In such situations, robotic re-sleeve gastrectomy is more than an opportunity to revise the procedure.   

Robotic Assistance for a Safer Surgery with Improved Results

The robotic platform improves the patient’s experience by boosting Dr. Bonnor’s manual endurance and fine motor skills and these parameters are highlighted with revision cases.[2] Usually, bariatric surgery is conducted laparoscopically. Laparoscopic surgery is a minimally invasive means of gaining access to the inside of the abdomen using only a keyhole incision and a laparoscope. A laparoscope is a tiny, fiber-optic camera mounted at the end of a thin cable. But robotically-assisted surgery offers all of laparoscopic surgery’s advantages and more.

Advantages of Robotically Assisted Surgery 

  • The operation only requires several small incisions
  • A camera provides a high-definition, 3D magnified view of the surgical site
  • The robot responds to your surgeon’s hand movements in real-time
  • Patients experience fewer complications than with laparoscopic surgery


Robotic “Re-Sleeve” Gastrectomy Houston

Candidates for robotic re-sleeve gastrectomy are patients who have previously undergone sleeve gastrectomy but have seen a stop to (or a complete reversal of) their post-op weight loss. Such stumbling blocks can be a common obstacle for bariatric patients. Despite surgical assistance and changes in nutrition,  weight loss is a challenging endeavor. Some patients may relapse because of some unexpected change in their lifestyle or financial circumstances.[3] If regaining weight or other complications arise, gastric sleeve revision surgery could be a consideration to reset your weight loss agenda and recommit to a healthy lifestyle.

In a robotic re-sleeve gastrectomy, Dr. Bonnor will reshape and resize the stomach pouch (or gastric “sleeve”) so that it will once again function to suppress your appetite. A properly functioning sleeve gastrectomy is intended to prevent you from gaining weight by consuming excess calories.[4] 

Often, patients who are in need of gastric sleeve revision have overstretched their truncated stomach pouch. The revision procedure will once again shrink the stomach down to a vertical “sleeve” about the length and diameter of a banana. 

The gastric sleeve surgery is considered to be more effective and less complicated than other, more involved bariatric surgeries, like gastric bypass. The sleeve technique does not require any rerouting of the intestinal tract. Nor does it diminish the rate at which your body will absorb nutrients from food. For these reasons, sleeve gastrectomy is the preferred weight-loss method. 

In more extreme cases of post-surgical weight gain, Dr. Bonnor may decide to perform a duodenal switch surgery. During duodenal switch surgery, the patient’s gastric sleeve is revised to a gastric bypass. The duodenal switch represents a more profound revision of the original gastric sleeve, but it may be necessary, depending on the severity of the patient’s situation. 

Frequently Asked Questions (FAQ)

How Much Does Robotic Re-Sleeve Gastrectomy Cost in Houston?

At your personal consultation, you will have the opportunity to have an evaluation and recommendations. Financing options are available for those who qualify. We also encourage you to enquire with your insurance provider. Because obesity affects so many aspects of one’s health,  medical plans will cover a portion of your expenses. 

Is Revision Surgery for primary weight loss surgery reimbursed by Insurance?

The exact amount your insurance provider may or may not cover your bariatric revision surgery depends upon a number of factors. These factors include the type of coverage you have and your deductible and coinsurance. In general, plans will cover part of your surgery if you have bariatric coverage and a BMI is greater than 40, or if you have a BMI of 35 along with a medical problem related to obesity. Many plans exclude bariatric surgery denying your coverage of this procedure regardless of your weight.

What is gastric sleeve revision surgery or re-calibration of a sleeve gastrectomy?

Gastric sleeve revision surgery is a procedure to recalibrate or reshape a previous gastric sleeve surgery. The purpose of this recalibration is to enhance portion control by reducing the size of the stomach either focused on the existing anatomic concern. In gastric sleeve surgery, the size of the stomach is reduced by 70 to 80%. Sometimes,  patients overstretch their stomach pouch, leading to poor portion control and other complications. Gastric re-sleeve will reduce the stomach pouch down to a more appropriate size.
