Final answer:
The Roux-en-Y technique is commonly used to repair the digestive tract in bariatric surgery for obesity treatment.
Step-by-step explanation:
The Roux-en-Y technique is most commonly used to repair the digestive tract in bariatric surgery, which is the most effective medical treatment for obesity. In this procedure, the main section of the stomach is closed off from the digestive tract, and a small pouch is formed to limit food intake. The jejunum is then directly attached to that pouch, bypassing the stomach and the duodenum to limit nutrient absorption.
This surgical procedure involves the creation of a small stomach pouch, which is then directly attached to the jejunum. As a result, the main section of the stomach along with the duodenum is bypassed, which restricts the intake of food and reduces the absorption of nutrients, thereby helping in weight loss.
