When weight loss efforts through lifestyle changes or medications have been proven unsuccessful, then bariatric surgery becomes a possible option.
For morbidly obese patients, bariatric surgery has fantastic results, prolonging the life of the patient, curing diabetes as well as aiding the loss of weight.
Quite often, this will be the only surgery needed to get the wanted result.
Types of Bariatric Surgery
- Restrictive Procedures – These work by reducing the size of the stomach (typically to the size of a cup).
- Malabsorptive Procedures – These work by decreasing the absorption of calories in small intestine.
Since bariatric surgery is a surgical procedure, it is performed under general anaesthesia. An intravenous line is placed for easy administration of medication and fluids. A breathing tube is inserted to help the patient breathe easily during the surgical procedure.
Your surgeon will perform Bariatric Surgery in one of two ways
- Open Method – Requires a single larger incision in the abdomen
- Laparoscopy – Requires several small keyhole incisions in the abdomen
Let’s look at the types of bariatric surgeries.
Gastric bypass surgery is a combination of both restriction and malabsorption. This is because is decreases the size of the patient’s stomach and reduces the absorption of calories in small intestine.
This is achieved by the use of surgical staples to create a smaller compartment of the stomach that now serves as the new stomach. The restricted portion of the stomach continues to secrete digestive juices but does not receive food.
The surgeon will then cut a section of the small intestine and attach one of the free ends to the smaller compartment of your stomach or the pouch and the other free end lower down the small intestine. This creates the trademark, Y shape. This is why the procedure may also often be called Roux-en-Y stomach surgery.
In essence, the surgeon has now created a bypass for food which avoids the lower stomach and initial part of small intestine thereby ensuring decreased calorie absorption.
Banding is a restrictive procedure which works by placing a band around the upper part of the stomach to create a small pouch that holds food. A tiny opening connects the pouch to the rest of the stomach.
The size of the pouch and the tiny opening connecting the pouch to the rest of the stomach ensured slow movement of food making one feel fuller quickly.
Adjustable Gastric Banding or Lap Band
Adjustable Gastric Banding is also a restrictive procedure which works exactly like gastric banding with just one exception. The band placed around the upper stomach is adjustable (and inflatable) so the size of the pouch could be adjusted based on requirement at any time.
Bilopancreatic Diversion is a malabsorptive procedure, that restricts the food intake and the amount of calories absorption in the small intestine. This works by removing a part of the stomach and leaving only a small pouch behind and then creating a direct route from the pouch to the end of the small intestine.
