Benefits of Biliopancreatic Duodenal Switch Bypass
Duodenal switch stomach surgery has greater weight loss benefits than more moderate bypass procedures (like roux-en-y) but poses greater nutritional problems. However, duodenal switch is less food restrictive than the roux-en-y bypass. The new stomach pouch can accommodate about 6 ounces of food compared with the roux stomach content of about 1 ounce. Given the greater malabsorption element in duodenal switch bypass compared to roux-en-y, it means that patients can eat more and still lose weight.
Weight Reduction Benefits
Duodenal switch stomach bypass is a highly effective treatment for clinical or morbid obesity. Patients typically lose 66 percent of their pre-operative excess weight within two years. In one patient study (125 subjects), excess weight loss of 74 percent at one year, 78 percent at two years, 81 percent at three years, 84 percent at four years, and 91 percent at five years was achieved. If duodenal switch bypass patients adhere strictly to their post-operative dietary and other lifestyle guidelines, they can expect to lose up to 80 percent of their excess weight and maintain this weight reduction, without weight regain, indefinitely. This weight loss alone can produce significant health benefits, like lower blood cholesterol, lower blood pressure, reduced risk of heart disease, diabetes and some cancers.
Health Benefits of Duodenal Switch Bypass
According to a recent study of 500 bariatric bypass patients, 96 percent of weight-related health conditions (eg. hypertension, back pain, sleep apnea, diabetes and depression) were improved or resolved.
Importance of Bariatric Patient Compliance
Despite the effectiveness of duodenal switch gastric bypass surgery, it is no easy answer to clinical obesity. The same pressures on patients to over-eat and take insufficient exercise that existed before the stomach bypass operation will exist in the post-operative period. Duodenal switch surgery offers patients an opportunity to change, rather than a quick solution to obesity.
