The Duodenal Switch is for people who are extremely obese (BMI of 50 or higher) or who have poorly controlled diabetes. The Switch involves both restrictive and malabsorptive components to produce long-term weight loss and improved control of blood sugar. In the restrictive portion of this procedure, the surgeon removes a large portion of your stomach. The new, smaller stomach is about the size of a banana, which limits the amount of food you can eat at once and helps you feel fuller after smaller meals.With the malabsorption portion, the path of your intestines is changed, which allows food to bypass part of the small intestine so you absorb fewer calories, carbohydrates and fat from the foods you eat, helping you lose weight. You will still need to commit to a healthy diet and active lifestyle if you want to maintain weight loss with this procedure.Since you cannot absorb vitamins and nutrients the same way you do before surgery, it is important to take supplements for the rest of your life

THE PROCEDURE

There are two components to the biliopancreatic diversion with duodenal switch procedure. First, a large portion of your stomach is removed. The new, smaller stomach is about the size and shape of a banana, which limits the amount of food you can eat at once and helps you feel fuller after smaller meals. Next, the first part of your small intestine is divided just after it leaves the stomach.Then, a loop of small intestine further down is attached to the cut end by the stomach, allowing food to bypass a significant portion of the small intestine. This allows the body to reduce the amount of calories and nutrients the body absorbs.

The duodenal switch works because the newly created stomach pouch is smaller and can only hold a few ounces of food at a time, which translates into fewer calories consumed. There is less digestion of food by the smaller stomach pouch, and the segment of small intestine that would normally absorb calories as well as nutrients no longer has food going through it, so there is less absorption of calories and nutrients. Most importantly, the rerouting of the digestive process produces changes in gut hormones that promote satiety, suppress hunger, and reverse one of the primary mechanisms by which obesity induces type 2 diabetes.

Duodenal Switch surgery can be performed as a laparoscopic or robotic (minimally invasive) procedure which involves the use of a small telescope-like camera inserted through a small incision made in the abdomen, or as an open procedure where a large midline incision is made in the abdomen. The robotic method is the most commonly used by Dr Swift in Baltimore, Maryland.

ADVANTAGES

  • Low mortality rate (0.2%)
  • Weight loss of 80-90% of pre-operative excess weight within one year
  • Overall improved health
  • Highest rates of resolution or elimination of co-morbidities such as type II diabetes, sleep apnea, hypertension and many others

DISADVANTAGES

  • Disruption of the staple line can lead to leakage or serious infection
  • Possible malnutrition or anemia
  • Possible obstruction of the GI tract
  • Possible frequent diarrhea and malodorous gas
  • Risk of dumping syndrome
  • Requires adherence to dietary recommendations, life-long vitamin/mineral supplementation, and follow-up compliance

PREVENTION OF REFLUX/GERD AFTER GASTRIC BYPASS (GASTRIC SLEEVE)

Morbidly obese patients prior to bariatric surgery suffer from a higher frequency of reflux symptoms compared to the general population. To minimize risk of significant GERD after bariatric surgery in Baltimore, Maryland we actively screen patients for symptoms of reflux and hiatal hernia.

If detected, we repair it at the time of bariatric procedure. This approach minimizes risk of possible delayed surgery for this condition which might be needed in about 10% of patients and greatly improve their quality of life after bariatric surgery

PREVENTION OF GALL BLADDER DISEASE AFTER BARIATRIC SURGERY

Morbidly obese patients are known to have a higher frequency of Gall Bladder disease both prior to and after bariatric surgery compared to the general population. Asymptomatic gall stones can cause acute inflammation with significant weight loss after bariatric surgery in 30-40% of patients. It is our policy to actively screen patients for gall bladder problems prior to surgery and if anything is detected (gall stones, chronic cholecystitis due to dyskinesia, cholesterol polyps), removal of the gall bladder would be recommended at the time of main bariatric procedure. Consequently, risk of repeat surgery for gall bladder surgery later on is avoided. If no problems with the gall bladder are detected, after bariatric surgery patients are treated with Ursodiol or Actigall for first six months after bariatric surgery in Baltimore, Maryland, to prevent problems with the gall bladder With that preventive treatment chances of developing that problem are reduced from 30-40% down to 2-5%.
