Laparoscopic (Roux- Y) classic gastric bypass:

The classic gastric bypass procedure is one of the earliest bariatric surgeries and has been done for over 50 years with a strong safety and efficacy profile. The surgery does not remove any part of the stomach and is therefore reversible. It involves creating a small stomach (gastric) pouch that is separated from the upper part of the stomach. After creating the pouch, the early part of the small intestine is disconnected from the duodenum. Then two connections are made, one connection is between the early part of the small intestines and gastric pouch while another connection is between the duodenum and later part of the small intestine. The larger separated stomach naturally leads to the duodenum, hence both of these structures are bypassed by the food that enters the small stomach pouch and routed to the small intestines. It is believed that both these structures are responsible for the hormones that lead to obesity and bypassing them helps to dramatically reduce those hormone levels. Hence the procedure is called a gastric bypass. The small gastric pouch will initially only take 3 bites a meal but later will loosen up and allow up to 6-8 bites as well. The surgery takes about 2 hours and the hospital stay is also 2 nights. The surgery will help lose about 70% of excess weight and can help treat 80% of diabetes. The effects of this surgery are better longer lasting than the sleeve gastrectomy. Most acid reflux symptoms disappear after this surgery and the chances of having acid reflux after this surgery is quite low. It is necessary to take vitamin supplements after this surgery as well.
