Laparoscopic Gastric Bypass

Laparoscopic Gastric Bypass is the most frequently performed bariatric procedure in the United States.  It works via both restriction and modest malabsorption.  In this procedure, stapling creates a small (15 to 20 ml) stomach pouch.  The remainder of the stomach is not removed, but is divided from the stomach pouch.  The outlet from this newly formed pouch empties directly into the lower portion of the jejunum, thus bypassing the duodenum and lower stomach.

Laparoscopic Gastric Bypass

Pros:

  • Proven method of weight loss and resulting resolution of many obesity- related conditions
  • No saline fills or adjustments
  • Highest rate of diabetes remission
  • Highest rate of heartburn resolution
  • Usually lose about 75-80% of your excess weight
  • Can be reversed
  • Dumping Syndrome mechanism helps patients avoid eating sugary foods

Cons:

  • As the result of the intestinal rerouting, the patient will react differently to sugar and will experience “dumping syndrome” (causing cramps, sweating, nausea, and vomiting) if they ingest more than 5 grams of sugar per serving of anything.  (This is good in a way as it decreases the likelihood the patient will ingest empty calories from sugary foods).
  • Must avoid Ibuprofen products such as Motrin, Alleve, Advil, etc. as these drugs could cause ulcers
