There are three general reasons for revision weight loss surgery:
1. There were complications after bariatric surgery and revisions were needed
2. Anticipated weight loss was not achieved following bariatric surgery
3. Weight was regained following bariatric surgery
A conversion to duodenal switch is one of the options for revision bariatric surgery.
Conversion to Duodenal Switch Explained
A conversion to duodenal switch limits the amount of food that can be absorbed by the stomach as well as the number of calories that are absorbed. Duodenal Switch is also referred to as vertical gastrectomy with duodenal switch, biliopancreatic diversion with duodenal switch, and gastric reduction duodenal switch.

A conversion to duodenal switch is one of the more complicated 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.
Conversion to Duodenal Switch Risks vs. Benefits
Duodenal Switch Surgery has greater potential for complications than other weight loss surgeries. People opt for this particular bariatric surgery because a Duodenal Switch revision surgery has some advantages over other types of weight loss surgery. Read: Duodenal Switch Risks and Complications.
The amount of weight that can be lost with Duodenal Switch is impressive. A 50% loss of excess weight in 85% of patients occurs within three years. In particular, Duodenal Switch is effective for those who have BMIs higher than fifty-five.
Duodenal Switch produces a greater weight loss for the super obese than Roux-en Y Gastric Bypass Surgery (for people with a BMI of at least fifty) according to research published in the Annals of Surgery. 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 the health issues that accompany obesity such as diabetes, hypercholesterolemia, hypertension, and sleep apnea.
Outcomes of Duodenal Switch vs. Gastric Bypass
A tracking study of 350 patients compared the results of Duodenal Switch Surgery to Gastric Bypass Surgery and found 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. Only sixty percent who had Gastric Bypass Surgery stopped taking their medications.
Sixty-eight percent of Duodenal Switch patients stopped taking medication for hypertension 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.
On the other hand, Dr. Mitchell Roslin, the chief of obesity surgery at Lenox Hill Hospital in New York City, believes in both the duodenal switch and the duodenal switch conversion. Read one patient’s story with the duodenal switch revision from the LapBand, “Jassira’s Story: Obesity Infertility to Motherhood.”
Duodenal Switch Revision Weight Loss Surgery Risk Analysis
Duodenal Switch weight loss surgery is only performed by a minimal number of bariatric surgeons. Even fewer bariatric surgeons perform Duodenal Switch Revision weight loss surgery.
Gastric Bypass conversion to Duodenal Switch owing to failed weight loss can provide beneficial outcomes. However, the complexity of this surgery increases the potential for complications even beyond the Duodenal Switch risk profile. Duodenal Switch Revision is best suited for a very select portion of the population.
Risk analysis is warranted. Consultations with medical professionals to evaluate surgeries is the best approach.
