OPEN GASTRIC BYPASS SURGERY: (THIS IS ONE SPECIFIC TYPE OF OBESITY SURGERY-ASK YOUR DOCTOR ABOUT ALL OTHER MEDICAL AND SURGICAL OPTIONS)

What is the procedure and how is it performed?
There are several surgical procedures that can assist severely overweight (obese) people with weight loss. Gastric bypass is one of the most extreme surgical procedure but also one of the most successful in terms of the amount of weight loss and the in keeping the weight off. It involves two components that make it so successful: restrictive and malabsorptive components. Restrictive refers to the new gastric pouch that is created. Malabsorptive is the reconnection of your intestine further downstream. This allows fewer calories to be absorbed by your intestines.




Gastric bypass surgery is performed under a general anesthesia (unconscious and pain-free). The beginning of the stomach is then stapled off to the size of golf ball. Part of the small intestine (jejunum) is then divided and the distal (far) portion (or Roux limb) is then brought up to the new gastric pouch and joined or anastomosed. This allows the food to bypass the rest of the stomach and beginning of the intestines. The other end of small intestine is then joined up to the Roux limb further downstream. This allows digestive juices from the stomach and organs to mix with the digested food further down. A tube may be inserted into your excluded portion of stomach and this will be removed in 4-6 weeks as an outpatient if you are doing well. The entire procedure usually takes about 4 hours.
