Laparoscopic Gastric Bypass as the name suggests is the Gastric Bypass surgery done by laparoscopic technology. Gastric Bypass, also known as Roux-en-Y Gastric Bypass is a bariatic surgery in which most of the part of the stomach is surgically stapled across the top to form a small stomach pouch as small as a walnut. This pouch is then connected to the small intestine, bypassing a large portion of small intestine. This causes the bypass of a major portion of the stomach and the duodenum. The food directly enters the jejunum. Thus, this process involves both the restrictive as well as malabsorption processes. Although food is not lower part of the stomach, it secretes digestive juices into small intestines and remains healthy.
Nowadays most of the surgeons perform this operation by using the laparoscope. It is a small tubular instrument with a camera attached through short incisions (4-5) in the abdomen. The tiny camera on the top of the scope allows the surgeon to see inside the abdomen. This is known as Laparoscopic Gastric Bypass.
But it should be remembered that everyone is not a candidate for laparoscopic gastric bypass surgery. If one is in the age group of 18-60 years, the BMI of the person should be 40 or more, and have diabetes or hypertension then you may be a candidate for this type of surgery provided all the weight loss treatments have been tried and lost. If one is over 60 years of age and already have had a surgical procedure for weight loss take nicotine in any form then you are not an ideal candidate for Laparoscopic Gastric bypass surgery. In any case a proper pre-operative evaluation is required by the surgeon before he declares one as a candidate for this procedure.
There are many benefits attached with Laparoscopic Gastric Bypass but the most important one is that it drastically reduces the complications which might occur during an ‘open’ surgery. One experiences less pain and faster healing after the surgery. There is a huge weight loss in the first year after surgery, which makes other medical problems such as diabetes, hypertension, and coronary artery disease easier to treat or they may be eliminated all together. Laparoscopy reduces the changes of development of hernias.
Since the stomach pouch is reduced to the size of a walnut, during the first six months of the surgery, it is important to not to eat very fast or too much as it may cause vomiting or intense pain. During the first three to six months of the surgery one may experience body aches, tiredness, felling cold, dry skin, hair thinning and hair loss and mood changes due to rapid weight loss. One may experience It may take some time to get into a new diet and exercise regime. After about two years of this surgery one may expect to lose around 50-60 % of the excess weight.
