A gastric reduction duodenal switch surgery is also known as a 'duodenal switch' (DS) procedure and biliopancreatic diversion with duodenal switch (BPD-DS).
This is a weight loss procedure that involves removing a major portion (around 70%) of the stomach to attain malabsorptive and restrictive aspects, this results in lesser absorption of food by the small intestine and hence, fewer calories. This surgery is considered as an ideal weight loss surgical procedure for people who are super-obese (with a BMI of 50 and higher).
This is a last-resort for losing weight by extremely obese people who have failed to achieve the desired results through all other weight loss non-surgical and surgical procedures.
You are considered as an ideal candidate for a gastric reduction duodenal switch surgery if you are super obese with a BMI of 50 or higher.
This is an effective weight loss procedure and is normally considered as a last resort for extremely obese people who have had other various non-surgical and surgical weight loss procedures but have had unsatisfactory results by them.
It is important to note that this is not a direct weight loss procedure rather it is an assistive weight loss method that helps you lose weight over a short period of time if you take all precautions and follow the doctor's instructions diligently.
The food you eat passes down the food pipe (esophagus) into the stomach and through it to the small intestine. The small intestine releases digestive juices to help break down the food and retrieve the nutrients from it. After the food gets digested the remaining waste is passed on to the larger intestine (colon) and excreted eventually from your body.
The gastric reduction duodenal switch surgery aims to basically decrease the size of the small intestine so that less amount of food gets converted into calories which eventually results in weight loss.
The procedure can be performed as a conventional open surgery or as a minimally invasive surgical procedure with the help of a laparoscope (thin, flexible surgical tube).
The main steps of this surgery involve:
This results in lesser portion of the smaller intestine being active in absorbing nutrients from the food before passing it along to the large intestines (colon) this acts as a restrictive and mal-absorptive procedure.
As with any other major surgery this surgery also carries certain risks, such as:
Gastric reduction duodenal switch surgery is highly effective and results in you losing around 75%-80% of excess weight and maintain this lower weight as well. The long-term success of this procedure also depends on the diligence you show in following the post-surgical instructions of the doctor regarding changes in diet, life style and other precautions that are advised.
