Definition: A weight-loss surgery that creates a long, narrow tube from the stomach and connects it directly to the small intestine further down, bypassing a significant portion of the intestine.
Procedure Steps:
- Anesthesia: General anesthesia.
- Access: Performed laparoscopically.
- Creating the Pouch: The stomach is divided to create a long, tubular gastric pouch.
- Bypass: This new stomach pouch is connected directly to the small intestine about 150-200 cm from the start (a single connection, or anastomosis).
- Closing: The incisions are closed.
Purpose / Benefits:
- Purpose: To achieve weight loss through both restriction (smaller stomach) and malabsorption (bypassing part of the intestine).
- Benefits:
- Effective weight loss and comorbidity resolution.
- Technically simpler and faster to perform than the classic bypass due to a single anastomosis.
- Can be a good option for higher BMI patients.
