Success Rate of Duodenal Switch Surgery
According to the Archives of Surgery, a study compared patients who had duodenal switch surgery with those who had gastric bypass surgery. This study looked at 1,545 DS patients and 77,406 gastric bypass patients from 2007 to 2010. They observed that sustained weight loss was more successful in duodenal switch surgery patients.
Two years following their weight loss surgery, the average amount of weight loss that was both sustained and maintained by DS patients was 79% versus just 67% in gastric bypass patients.
The same research found that as many as 20% of gastric bypass patients failed to lose half of their excess body mass index or BMI at the one-year follow-up mark as well as at their two-year appointment. While duodenal switch surgery patients only had a 9% and 6% failure rate respectively.

A study showed that an overall total cholesterol decrease of .24 mmol/L occurred in gastric bypass surgery patients. While a reduction of 1.07 mmol/L occurred in duodenal switch surgery patients.
Low-density lipoprotein, anthropometric measures, fat-free mass reductions, and fat masses, in general, were more common in patients who had duodenal switch surgery versus gastric bypass surgery. Both groups experience glucose concentration reductions, C-reactive protein reductions, as well as blood pressure reading reductions. There was no large difference between the groups.
