The Benefits of Sleeve Gastrectomy with Duodenal Switch
Sleeve gastrectomy is commonly referred to as the vertical sleeve gastrectomy or Duodenal Switch, and usually not performed as often as some of the other highly popular weight loss surgeries. There are normally about 20,000 duodenal switch procedures performed each year in the United States. The procedure combines two common bariatric surgeries together to bring about a comfortable and effective outcome.
The duodenal switch procedure combines the vertical sleeve gastrectomy procedure with the duodenal switch and provides obese patients with the best and most highly effective chance for weight loss. This procedure if highly effective for patients who have a BMI (body mass index) of 55 or higher. While the procedure may work on patients with a slightly lower BMI, it is commonly offered to patients with a much higher BMI. Not only does the surgery reduce the stomach size but also reduces the amount of calories and nutrients that the body can absorb.
How the Surgery Works
The duodenum is a portion of the small intestine that lies at the front (or the first portion) and attaches to the last six feet of the small intestine. This region is where food is digested and rejoined to approximately 12 feet of the intestine. Surgery on this area causes a restriction of the volume of food that can be eaten at once. The surgery can cause a slight malabsorption of fat which leads to diarrhea and feelings of being bloated.
What to Expect with Surgery
Most patients can expect to lose a significant amount of weight when undergoing sleeve gastrectomy with duodenal switch. Patients commonly lose 75% of excess weight. There are patients who can lose too much weight with this procedure which is why after-care is so important. Highly skilled and experienced surgeons will require an extensive follow-up care plan that involves routine examinations post-surgery to monitor results and weight loss.
Following surgery patients must eat three meals per day and strictly consume the allotted amount of protein and vitamins provided by the doctor. This will ensure that no nutrient deficiency occurs. Multivitamins, calcium and iron are commonly taken after surgery. Iron is highly recommended to menstruating women to avoid iron deficiency. The overall procedure is highly effective if the patient follows the strict guidelines and after-care plan provided by the bariatric surgeon.
Possible Side Effects
While the results and benefits of sleeve gastrectomy are immense there are possible side effects and complications that can arise. A qualified surgeon will explain the possibility of these side effects to you before undergoing surgery so that you can prepare yourself and know what to expect. A solid after-care plan and adherence to the post-op treatment will greatly reduce the risk for complications and side effects.
