gastric pouch
The small stomach remnant created during certain bariatric procedures to restrict food intake.
Full Definition
A gastric pouch is the small functional stomach created during restrictive and malabsorptive bariatric procedures such as Roux-en-Y gastric bypass and sleeve gastrectomy. Typically 15-30 mL in volume, the pouch serves to dramatically limit food intake by creating early satiety. The size and integrity of the gastric pouch are critical factors in long-term surgical success. Pouch dilation can occur over time and may require revision surgery. In bypass procedures, the pouch is completely separated from the remainder of the stomach, while in sleeve gastrectomy, it represents the tubular stomach remnant.
