Surgical procedures currently being performed for morbid obesity include:
- Gastric Bypass (open or laparoscopic)
- Gastric Banding
- Laparoscopic Adjustable Banding
- Biliopancreatic Diversion
- Longitudinal Gastric Resection Duodenal Switch (LGRDS) (DS) (GRDS)
- Duodenal Switch
- Sleeve Gastrectomy
- Revisions:
- from Roux- en -Y Gastric Bypass to Duodenal Switch
- from Lap-Band to Duodenal Switch
- and adjustments of failed Duodenal Switch surgery
There are three different types of Bariatric surgery.
- Restrictive - different types of stomach banding or stapling procedures
- Malabsorptive - ileo-jejunal bypass
- Restrictive/Malabsorptive - gastric bypass (open or laparoscopic) - mostly restrictive procedure
- GRDS or LGRDS or DS - primarily a malabsorptive procedure with a restrictive component involving a partial gastric/stomach resection
The restrictive component modifies the stomach into a 3-4oz. (approximately 80cc) pouch reducing food intake. The malabsorptive component bypasses part of the small bowel (approximately 60%) causing a decrease in food absorption.
