Laparoscopic Gastric Bypass Surgery

Gastric_BypassGastric Bypass Surgery separates the stomach into two unequal compartments with less than 5% of the stomach remaining usable for food consumption. During digestion, the food empties from this tiny stomach pouch into the upper intestine. Watch a Gastric Bypass Procedure Video Now>

The procedure is performed with a state-of-the-art imaging and tiny keyhole incisions. The operation is usually completed in about two hours. Our average hospital length of stay is slightly less than 48 hours.

Roux-en-Y Gastric Bypass Surgery closes off the upper stomach and separates it from the remaining lower stomach below the staples. This creates a small stomach pouch about as big as a shot glass (one ounce/30 cc). The upper intestine is cut with the distal end connected to the stomach pouch creating a stoma (or exit) from the pouch into the rest of the digestive tract. The end of the cut intestine is reconnected to the upper intestine at a measured distance below the stoma in a “Y” configuration.

Gastric Bypass Surgery vs. LAP-BAND®
Weight loss has been shown to occur more rapidly and over a longer period of time with gastric bypass as opposed to laparoscopic banding. The reasons for superior weight loss stem from the small degree of malabsorption caused by bypassing nearly all of the stomach and the first two feet of the small intestine. To date, weight loss with gastric bypass has been much more consistent than with other gastric restrictive procedures.

Is gastric bypass surgery reversible?
Yes, gastric bypass is a reversible procedure. However its reversal would require an operation of the same or greater magnitude and risk as the original procedure.

How well does gastric bypass surgery work?
Gastric bypass surgery enables you to feel full while eating much less. Food travels from the mouth to the esophagus to the stomach pouch through the stoma. It then moves into the rerouted intestine, bypassing a portion of the original intestine. This results in reduced calorie and nutrition absorption (malabsorption). Gastric bypass often allows patients to lose 65%-70% of their excess weight within one year, with very few early failures.
