Do you find yourself gorging on a variety of food items? Do you think that people call you a glutton? Are you chewing your nails to find out a way to reduce your super-human appetite? Well, gastric bypass could be your solution.
What is Gastric Bypass?
Before venturing out to know the ins and outs of gastric surgery, you first need to become familiar with the structure of that muscular pouch in your body which is scientifically called the stomach. The stomach is a sack of muscles which begins with the end of the food pipe or the oesophagus and ends with the beginning of the small intestine. The stomach is where the food you eat goes and gets mixed with the digestive juices and hydrochloric acid secreted thereby beginning the process of digestion.
Gastric bypass aims at dividing the stomach into two parts…one smaller upper part and the other larger lower part. The whole idea rests on the mechanism of working of the stomach. The oesophagus or the food pipe opens into the stomach and contains two muscular flaps which closes once the stomach is full thereby creating a general disinclination towards food till the stomach is empty and all the food is digested.
The larger lower pouch thus created can be considered to be a sort of remnant pouch. The small intestine is accordingly rearranged and connected. It must be noted that any such artificial restructuring of the stomach produces a marked decline in the intake capacity of the stomach and also affects its interaction with the food.
How is Gastric Bypass done?
- The surgery is done using the minimally invasive Laparoscopy.
- The Roux-en-Y Laparoscopic Gastric Bypass performed for the first time in the year 1993 was one of the most complicated and difficult operations done using this minimum access technique.
- The surgery aims at creating a small thumb sized pouch of approximate capacity 15-30ml in the upper region of the stomach and a lower but larger second chamber of capacity around 400ml.
- The procedure is either done using surgical staples or the stomach is permanently divided so as to negate the chances of the two sections getting healed up.
- This division is also accompanied with the rearrangement and bypass of the gastro intestinal tract.
Who should go for Gastric Bypass?
- Care must be given to the fact that Gastric Bypass is no ordinary surgery and is suggested to patients suffering from extreme cases of obesity or type-2 diabetes or hypertension.
- Patients undergoing Gastric Bypass experience a dramatic reduction in weight.
Success rate of the Gastric Bypass
- Although the surgery is gradually becoming popular, however, like any surgical procedure, the Gastric Bypass is also not devoid of complications.
- Complications include anastomotic stricture, anastomotic leakage or ulcer and in some cases severe nutritional deficiencies.
- 15% of people undergoing the surgery face mild to severe complications .
- Survey has proved that around 0.5 % of the people facing complications after the surgery have succumbed to it.
However, with the advancement of medical sciences, the complications are being negated gradually and the Gastric Bypass could certainly be an option for extreme cases of obesity and hypertension.
