Duodenal switch is a weight-loss procedure combining intestinal bypass and gastrectomy. The surgery is primarily suitable for individuals with severe obesity.
Duodenal switch is a complex weight-loss procedure primarily reserved for individuals with severe obesity. It combines two techniques:
Gastrectomy: removing part of your stomach.
Intestinal bypass: rerouting your intestines.
The surgery limits how much your stomach can hold and reduces the nutrients your intestines can take from food. The surgery also cuts down on hunger hormones from your stomach and intestines.
Duodenal switch treatment is generally performed for those who have obesity. If you cannot lose weight through traditional methods and treatments, you may get an appointment with your doctor to check your surgical options. You may be a good candidate for duodenal switch operation if you fulfill the criteria below:
Duodenal switch treatment combines two different types of surgery for weight loss.
The restrictive part of the duodenal switch surgery focuses on reducing the size of your stomach. This is done by removing a large portion of it, like a sleeve gastrectomy. After the surgery, your stomach can hold much less food than before. This limitation means you will feel full quicker and eat less, aiding in weight loss.
The malabsorptive aspect of this surgery changes how your body absorbs food. By rerouting and bypassing a significant part of your small intestine, the surgery ensures that your body absorbs fewer calories and nutrients from the food you eat. This is a key factor in weight loss, as the reduced absorption contributes significantly to the overall effect of the surgery.
Duodenal switch, or DS in short, is a surgery containing several steps for the whole procedure. You can check below to get brief information about the process:
Laparoscopic Surgery
This modern technique involves making small incisions and using specialized instruments. It is favored for its minimal invasiveness, reduced pain, and quicker recovery.
Open Surgery
In some cases, traditional open surgery might be necessary. It involves a larger incision and is typically used when laparoscopic surgery isn't suitable.
Step 1: Sleeve Gastrectomy
The first phase of the DS procedure is reducing the size of the stomach. About 65% of the stomach is removed, leaving a smaller, tube-like stomach. This limits the amount of food you can eat and helps you feel full faster.
Step 2: Intestinal Bypass
The next phase of losing weight surgery involves rerouting a portion of the small intestine. This process creates two pathways and a common channel. The shorter path for food limits calorie and nutrient absorption, aiding in weight loss.
Original Duodenal Switch (Biliopancreatic Diversion)
This method involves bypassing a larger portion of the small intestine (about 80–90%). It's more effective for weight loss but has a higher risk of nutritional deficiencies.
Modified Duodenal Switch (Loop DS)
A less extensive version bypasses about 50–60% of the small intestine. This method is simpler and has a lower risk of nutritional deficiencies.
Duodenal switch requires comprehensive follow-up and post-surgery care. Because, after the surgery, you will need to ensure long-term results, which are possible with an aftercare procedure.
Duodenal switch helps you lose more weight and reduces your ability to gain weight by preventing you from absorbing calories, minerals, or vitamins. The procedure of the gastric switch, of course, offers both risks and benefits.
The recovery time for duodenal switch surgery typically ranges from 2 to 4 weeks for initial healing. However, full recovery and adaptation to lifestyle changes can take several months. The recovery time varies based on your overall health, the specific surgical approach used, and your discipline after the procedure.
The main disadvantage is the risk of long-term nutritional deficiencies due to reduced nutrient absorption. Therefore, patients are required to consume lifelong vitamins and mineral supplements. It also entails a significant, permanent change to the digestive system.
In addition to health issues, one of the disadvantages of this surgery is its costs. Even though duodenal switch cost may vary according to your doctor’s experience or your overall health, the surgery is generally not covered by insurance. So, before making your mind about this operation, you should be prepared financially as well.
Duodenal switch surgery is one of the best weight loss surgery combining sleeve gastrectomy (reducing stomach size) with a small intestine bypass. The operation leads to reduced food intake and nutrient absorption. It is effective for significant, long-term weight loss and improving obesity-related conditions.
