Abdominal Bypass Surgery
A View Of Abdominal Bypass Surgery
Abdominal bypass surgery or Gastric bypass surgery as it is usually called, is a group of surgical procedures where the stomach is divided into two pouches: a smaller upper pouch and a larger lower pouch. In most instances a large part of the intestines will also be bypassed. In this type of operation, there is a remarkable decrease in the capacity or volume of content that the stomach can contain and the amount of nutrients that are aborbed by the body.
Abdominal bypass surgery is done primarily to deal morbid obesity. Morbid obesity is having a BMI or body mass index greater than 40. Other conditions where abdominal bypass surgery is indicated are type 2 diabetes, sleep apnea, and hypertension. Bariatric surgery is the umbrella term for all surgeries dealing with morbid obesity and abdominal bypass surgery is under this umbrella. The main goal for this operation is of course, weight loss.
There are several surgical techniques and forms of abdominal bypass surgery. One of these is laparascopic gastric bypass. Laparascopy is performed by making small incisions which allow a minute camera and any surgical devices needed to perform the surgery. The camera will provide a visual imaging of the internals allowing the surgeon to see the body parts that he/she needs to operate on.
The first laparascopic bypass surgery was done in 1993, making this kind of operation famous. The limited access technique of laparascopy lessened problems such as a long hospital confinement, scarring, recovery period, discomfort and the risk for incisional hernia. Other variations of abdominal bypass surgery are gastric bypass Roux en-Y (proximal) gastric bypass Roux en-Y (distal) and loop gastric bypass (mini-gastric bypass).
So how does abdominal bypass surgery works to lose weight? The stomach is a muscular, hollow organ that has a large stretching ability. When you consume food or drink it goes straight to the stomach. The stomach will then stretch to contain your intake, and will send a message to the brain when you are full. The brain will then send a message in return that yes, you are full and you need to stop eating.
In abdominal bypass surgery the space of the stomach is greatly decreased, thus limiting its stretching capacity and its volume content. When you eat a small amount of food, you will quickly feel that you are already full. Of course decreasing food intake means decreasing calorie intake, leading to weight loss.
There are a lot of abdominal bypass surgeries done in the United States and even around the world. Most of them are successful provided positive results. However, there are also possible complications for abdominal bypass surgery just like any other surgical procedure. These include infection, hemorrhage, hernia, venous thromboembolism and obstruction of bowel. Other complications are also possible such as nutritional deficiency, anastomotic leakage, stricture and ulcers.
