Duodenal switch, also known as biliopancreatic diversion with duodenal switch, or vertical gastrectomy, is an effective weight loss procedure. This procedure provides long-term weight loss for those people who are severely obese. The duodenal surgery basically limits the amount of food that a stomach can hold and number of calories that can be easily absorbed by the body.
Malabsorptive and restrictive procedure components are combined by the duodenal switch procedure. The purpose is to provide maximum and quick weight loss results that can be maintained for a long period of time.
Malabsorptive: The portions of the small intestine are re-routed in the malabsorptive component of the duodenal switch method. This re-routing is done for creating 2 separate pathways through the duodenum into the lower part of the small intestine. The aim of this method is to decrease the quantity of calories that a body can absorb. This is done by restricting the food and seeing how long it can mix with digestive juices before moving into the large intestine.
Restrictive: During the initial part of the duodenal surgery, there is a removal of the outer curvature of the stomach. The rest remaining part of the stomach is shaped into a slim and long sleeve called as vertical sleeve gastrectomy. The vertical sleeve gastrectomy maintains the pyloric valve in its place that is not possible in other gastrectomies. This is done for controlling the movement of the food into the small intestine that removes the risk of dumping syndrome in a patient. This procedure also keeps away other complications of stoma closure and blockages.
Some of its benefits include –
This procedure is also termed as biliopancreatic diversion with duodenal switch that helps in weight reduction of about 45-55% of excess body weight. This range is much higher as compared to laparoscopic adjustable gastric banding procedures. One of the advantages of sleeve gastrectomy is that it preserves Pyloric Valve which regulates the emptying of the stomach while preserving certain centimeters of the duodenum. This procedure is performed laparoscopically where a small stomach pouch of 120cc size is created with the help of stapling devices. The remaining stomach part is also removed. In this procedure the stomach is simply reduced and the gastrointestinal tract is not changed.
This procedure effectively limits the food intake that provides for maximum weight loss. A sleeve gastrectomy patient will now be able to eat a cup of food in three times a day and will feel more full and satisfied after eating small amount of food. A patient will now be able to control his/her cravings and hunger.
India is considered as a healthcare hub for many international patients that offer cost-effective duodenal switch surgery. Low-cost surgeries along with latest medical facilities have attracted many national as well as international patients to India.
A patient who undergoes duodenal switch surgery can expect to lose about 29-37% of excess weight in the first three months.
