Duodenal Switch Surgery
Of all of the different forms of weight loss surgery which are nowadays the sleeve gastrectomy with duodenal switch is perhaps the most .
What is Duodenal Switch Surgery?
The Duodenal Switch procedure, also known as the Bilio-Pancreatic Diversion with Duodenal Switch procedure or the Vertical Gastrectomy with the Duodenal Switch. This procedure generates weight loss by restricting the amount of food that can be eaten with the removal of stomach or vertical Gastrectomy (the greater curvature so that the volume is approximately one third its original) and by limiting the amount of food, specifically fat, that is absorbed into the body Duodenal Switch. This has a significant component of malabsorption, which seems to augment and help maintain long-term weight loss..
Who is an ideal candidate Duodenal Switch Surgery ?
If a person meets the following guidelines, weight loss surgery may be an appropriate measure for permanent weight loss : -
* Be age 40 or more
* BMI of 35 or over with serious obesity-related illnesses such as : -
1. Diagnosed with Diabetes Mellitus Type 2, Coronary Heart Disease or Sleep Apnea
2. Have a complete understanding of the procedure and the lifestyle changes necessary afterwards.
Effectiveness Percentages of weight loss of the excess weight
3 months 29 - 37%
6 months 51 - 55%
24 months 80-91%
Duodenal Switch Surgery how it works?
The initial part of this procedure is a sleeve gastrectomy in which the stomach is divided vertically and approximately eighty-five percent is removed. The small sleeve shaped stomach which remains retains the original outlet to the intestines and functions just like a normal stomach. This initial part of the surgery is aimed purely at restricting the quantity of food that can be consumed and this restrictive surgery cannot be reversed.
The second phase of the operation is to make the duodenal switch adding in an element of malabsorption surgery that is largely reversible. Unlike restrictive surgery that causes a loss in weight by physically preventing the patient from eating too great a quantity of food, malabsorption surgery contols the body's power to absorb calories from a meal as it passes through the digestive tract.
During surgery the intestine is divided and a relatively small section (generally approximately 150 cm in length) is used to make a bypass from the duodenum, which is situated near to the outlet of the stomach, to a point near the end of the intestinal tract thereby bypassing the major part of the digestive tract. The consequence of this duodenal switch is that food that passes through the intestinal tract only mixes with the body's digestive juices in the short final section of the intestine below the switch thus allowing the digestive juices very little time to digest the food and absorb calories from it.
Advantages of Duodenal Switch Surgery : -
The main advantage of the Duodenal Switch surgery is that by using two approaches, weight loss tends to be achieved more quickly and more permanently.
The more normal stomach allows for better eating quality
The patient experiences no Dumping Syndrome because the pylorus is preserved as the pyloric valve between the stomach and small intestine is preserved. People who have undergone the DS do not experience the Dumping Syndrome common with people who have undergone the Roux-en-Y Gastric Bypass Surgery. Those who undergo the Duodenal Switch often find that comorbidities such as Dumping Syndrome, Diabetes mellitus Type 2, Arthritis, and high blood pressure are significantly relieved in a short time after the surgery..
Risks and Complications : -
Despite the fact that duodenal switch weight loss surgery enjoys the advantage of providing weight loss using both restriction and malabsorption, it is the extent to which the malabsorption element dominates in the duodenal switch that gives rise to a lot of the argument which surrounds this type of surgery. By way of comparison, the traditional Roux-en-Y operation has a much shorter bypass and the length of intestine over which food is digested is about five times greater
The argument that many surgeons use against the duodenal switch is simply that insufficient absorption takes place so that there is too great a danger of anemia, protein deficiency and metabolic bone disease. The sleeve gastrectomy with duodenal switch is also debatably the most complicated type of weight loss surgery and a lot of surgeons think that it carries an unacceptable level of risk..
