Conversion of Gastric Bypass to Duodenal Switch Revision Weight Loss Surgery - My Bariatric Life
The subject matter of Gastric Bypass Revision Surgery has been given much attention in previous posts, but I will touch again on why revisions are sought by many patients who have had Gastric Bypass Surgery.
Three General Reasons for Revision Weight Loss Surgery:
1. Complications present following bariatric surgery and revisions are needed as corrective measures
2. Anticipated weight loss was not achieved following bariatric surgery
3. Weight is regained following bariatric surgery
Duodenal Switch Surgery Explained
A detailed explanation of the Duodenal Switch Procedure was given in a prior post titled "Is Duodenal Switch the Right Weight-Loss Surgery for You." Basically, Duodenal Switch Surgery is a method that limits the amount of food that can be absorbed by the stomach as well as the number of calories absorbed and used by the body. Duodenal Switch also is referred to as vertical gastrectomy with duodenal switch, biliopancreatic diversion with duodenal switch, and gastric reduction duodenal switch.
Duodenal Switch Surgery is one of the more complex weight loss surgeries and can cost from twenty to thirty thousand dollars. An additional $1,500 dollars will be spent annually on bariatric vitamins and supplements.
Duodenal Switch Risks vs. Benefits
The complexity of Duodenal Switch Surgery creates potential for greater complications following the procedure, as compared to the nature of complications that follow other types of weight loss surgeries. Why then, would a person opt for this particular type of surgery? The basic answer is that Duodenal Switch Surgery has some advantages over other types of weight loss surgery.
To begin, the amount of weight that can be lost with Duodenal Switch is impressive, amounting to a 50% loss of excess weight in 85% of patients in a three year period. In particular, Duodenal Switch may be quite effective for those who have BMIs higher than fifty-five.
It has been found that Duodenal Switch produces a greater weight loss than does Roux-en Y Gastric Bypass Surgery for people with a BMI of at least fifty. In addition, Roux-en Y Gastric Bypass has minimal malabsorption compared to Duodenal Switch. Malabsorption is important because it helps to increase and maintain long-term weight loss.
Duodenal Switch Surgery is perhaps the best procedure for addressing health issues that usually accompany obesity such as diabetes, hyper-cholesterolemia, hypertension, and sleep apnea.
Outcomes of Duodenal Switch vs. Gastric Bypass
A tracking study that compared the results of Duodenal Switch Surgery to Gastric Bypass Surgery in 350 patients discovered that Duodenal Switch had significantly better postoperative results than Gastric Bypass:
- All of the Duodenal Switch patients stopped taking their medications for Type 2 diabetes as opposed to sixty percent who had Gastric Bypass Surgery.
- Sixty-eight percent of Duodenal Switch patients stopped taking medication for hypertension as compared to 38.6% of Gastric Bypass patients.
- Seventy-two percent of Duodenal Switch patients stopped taking medication for high cholesterol compared to twenty-six percent of Gastric Bypass patients.
Duodenal Switch Risk Analysis
While Duodenal Switch Surgery has impressive results, it is a procedure best suited for high-risk patients or the "super-obese." It is contested by many who believe that the complications of the surgery outweigh the benefits and was even noted as "an operation that should probably go away" by a professor and surgeon at the University of Texas Southwestern Medical Center.
Duodenal Switch Revision Weight Loss Surgery Risk Analysis
Duodenal Switch weight loss surgery is performed by a minimal number of bariatric surgeons worldwide. Even fewer bariatric surgeons perform Conversion of Gastric Bypass to Duodenal Switch Revision weight loss surgery.
Conversion of Gastric Bypass to Duodenal Switch Revision weight loss surgery has its benefits. However, the high complexity of this revision surgery increases the potential for complications beyond the standard Duodenal Switch risk profile. Duodenal Switch Revision presents as a weight loss surgery that is best suited for a very select portion of the population.
A well-considered risk analysis is warranted. In depth consultation with medical professionals to evaluate surgeries is usually the best approach, but I imagine you were already aware of this. I wish good judgment and good luck to you.
