3 Classifications of Bariatric Surgery:

• Predominantly Malabsorptive Procedures - these operations reduce the stomach size but their main purpose is to create malabsorption inside the body.

Biliopancreatic Diversion (BPD)

This complex operation is also known as Scopinaro procedure. This kind of Bariatric surgery is now rare because of the problems in malnourishment observed in some the patients who have undergone this procedure. A part of the stomach is resected, creating a smaller stomach pouch. The distal part of the small intestine is then connected to the pouch, bypassing the duodenum and jejunum. This is the main reason for the severe malabsorption of nutrients resulting in nutritional deficiency. Patients who have undergone this procedure must have the need for additional vitamin and mineral supplements intake, even exceeding the normal dosage to keep up with the malnourishment they experience.

Jejuno-ileal Bypass (JI)

This operation is performed by dividing the proximal jejunum and then connecting the top end of the jejunum into the ileum which is located further down the small intestine. The food taken in by the patient does not pass through all the absorptive areas of the jejunum making them very susceptible to malnourishment and even liver failure because of lack of proper nourishment. This is just a few of the reasons why this procedure is no longer performed.

• Predominantly Restrictive Procedures - these procedures mainly concerns reducing the size of the stomach.

Vertical Banded Gastroplasty

This procedure is also known as the Mason procedure or stomach stapling. The procedure involves permanently stapling a part of the stomach to create a smaller pre-stomach pouch. This will serve as the new stomach.
