What does the "Roux-en-Y" refer to in surgery?

The term "Roux-en-Y" specifically refers to a surgical technique commonly used in gastric bypass procedures. In this approach, a small pouch is created from the stomach and connected directly to the jejunum, bypassing a significant portion of the stomach and initial part of the small intestine (the duodenum). This configuration has the effect of not only reducing the amount of food that can be consumed but also altering the body's hormonal response to food intake, leading to weight loss and improvements in obesity-related comorbidities.

The name "Roux" comes from the French surgeon, Dr. César Roux, who developed this method, and the “Y” shape describes how two portions of the intestines are connected. This surgical strategy is widely used for obesity treatment, particularly in patients with severe obesity or those who have not had success with other weight loss methods.

Other choices refer to different surgical procedures or classifications not related to the Roux-en-Y technique. For example, the laparoscopic cholecystectomy is a minimally invasive procedure to remove the gallbladder and does not involve the Roux-en-Y method. Hernia repairs utilize various techniques, but they do not include the Roux-en-Y approach. Classifications of colorectal lesions
