RNY Gastric Bypass Surgery

Bariatric Surgery Techniques are classified in two different groups according with their mechanism of action as follows:

1. Restrictive Procedures
2. Malabsortion Procedures

Restrictive Procedures (Lap-band, Vertical Banded Gastroplasty)

Restrictive procedures decrease food intake by creating a small gastric pouch (with no more than 1 ounce capacity) that generates an early fullness sensation and stops the patient from further eating.

With a restrictive procedure you may lose 35% – 40% of your excess weight after gastric bypass surgery.
Malabsortive Procedures (Biliopancreatic Diversion)

This kind of surgery procedure alters the digestive flow, causing the food to be poorly digested and incompletely absorbed, especially carbohydrates and fat.
RNY Gastric Bypass COMBINES THESE TWO DIFFERENT MECHANISMS:

1. It creates a small gastric pouch (as in the Restrictive Procedures)
2. Diverts the digestive flow (as in the Malabsortion Procedures)

These two different mechanisms of surgery ACT SYNERGICLY producing the best results in sustained weight loss (75% – 80% of your excess weight).

“Sugarman, Capella and others have also reported that Gastric Bypass procedures resulted in significantly greater sustained weight loss when compared to patients undergoing gastric restrictive procedures ”

Gastric Bypass Surgery has also the lowest reintervention rates and the best patient compliance with the new life style and diet.
