Mini Gastric Bypass

The mIni gastric bypass is a type of bariatric surgery which is less invasive and reversible and helps in weight loss based on restrictive and malabsorptive elements.

The surgeon makes few tiny incisions in the abdomen and enters the abdominal cavity through access ports. The stomach is divided into two parts and the long narrow tube serves as the new ‘mini’ stomach and the remaining large part if the stomach does not receive food. A part of the small intestine is cut and attached to this mini stomach using staplers. The length if the small intestine bypassed varies from patient to patient between 3 to 7 feet. Creating a small stomach helps in restricting the amount of food intake and by passing a major portion of the small intestine helps in less malabsorption of calories thus aiding in weight loss. Mini gastric by pass also results in the fall of the hunger hormone ‘Gherlin’ resulting in a reduced appetite.


Benefits of Mini gastric by pass:

  • It is a reversible procedure
  • The procedure is of shorter duration as compared to Roux-en-Y Gastric by pass
  • Short hospital stay and quick recovery


Risks associated:

  • Leak of staple line
  • Person can re-gain some weight if dietary changes are not followed in long term
