Duodenal switch surgery is also known as vertical gastrectomy. It is considered as one of most difficult weight loss surgeries. There are two surgical techniques in duodenal switch surgery. One is known as restrictive and other one is malabsorptive. Reducing the size of stomach is included in the restrictive component. Surgeon will remove some portion of the stomach through the surgery.
Malabsorptive surgery aims to reduce the nutrients and calorie absorption of the body. Through this surgery, the flow of food from the flow of pancreatic juices and bile are separated. The small intestine is rearranged and thus digestive juices and food interact only in the lower 20 to 24 inches of intestine. Thus only a few amounts of calories are absorbed by the body. This operation helps individuals to maintain long-term weight loss.
In gastric surgery, weight loss is attained by reducing the hunger of individuals. Due to this, gastric surgery may cause dumping syndrome in individuals. The quick entry of food often cause dumping syndrome. All these drawbacks are eliminated in duodenal switch surgery. But duodenal surgery also possesses some potential complications. Duodenal surgery is quite similar to a surgical procedure called biliopancreatic diversion.
Biliopancreatic diversion involves many adverse effects like complicated protein-calorie malnutrition and ulcers. Duodenal procedure leaves a vast portion of stomach intact. This portion include pyloric valve too. The pyloric valve is the main part that controls the discharge of stomach content into the small intestine. After this surgery, a small portion of the duodenum is also kept in the digestive system.
A pre-surgery consultation is essential for duodenal switch surgery. Physician will analyze the health condition of heart and lungs of the patients. The mental health of the patient is also evaluated. Physician will conduct endoscopy on some patients to verify whether there are any polyps, ulcers or tumors in their stomach. Doctors will make a clear analysis about the medication, herbal treatments, vitamins and minerals that the patient is taking.
Weight loss surgery is the most effective solution for individual suffering from morbid obesity. But you have to undergo weight loss surgeries only after trying all other natural and simple forms of weight loss. A good fitness plan and healthy life style will reduce the body weight to a great extent.
