bariatric surgery:some alternatives of stomach-reduction surgery against obesity

Vertical banded gastroplasty (VBG)

 

 

 

Surgical clamps are used to divide the stomach into two parts. In the top is smaller, which limits the room for food. The food comes out of the top to the bottom through a small opening. A bandage is placed around the opening so that it does not expand. The risks of vertical banded gastroplasty include the resurfacing of the bandage and failure in the line of staples. In small number of cases, stomach juices may leak to the abdomen or may happen infections or death resulting from complications. 


Laparoscopic adjustable gastric banding (LAGB, Lag-Band)  

 

 

 

An inflatable gastric band is placed around the upper stomach to create a smaller pouch and a narrow passage for the rest of the stomach. This limits the consumption of food and creates feeling of early satiety. When the band is put in place it is inflated with saline. The band is adjustable to increase or decrease the amount of saline solution to change the size of passage. This use of band is only for people with severe obesity - those with at least 45 kg of weight or above with more than twice the ideal weight - that failed to lose weight using other methods such as supervised diets and exercise. This operation aims to stay in place permanently, but can be removed if necessary. People who have the band need to diet and exercise to maintain weight loss. Complications can include nausea and vomiting, burning in the stomach, abdominal pain and sliding of band.

 

Derivation of Roux-en-Y gastric bypass (RGB).

 

The surgeon makes a reduction of the stomach using surgical staples to create a smaller stomach pouch. The stomach pouch is attached to the intestine. The food strayed from the top of the stomach and intestine and for the middle part of the small intestine through a small opening. The gap in the stomach limits the amount of food that a person can eat. By diverting a portion of the intestine, the amount of calories and nutrients absorbed is reduced. The small opening reduces the rate at which the food leaves the stomach pouch. One risk to the patient is when the stomach contents too fast to the intestine. Symptoms may include nausea, weakness, sweating and diarrhea after eating. Side effects include infection, leaking, pulmonary embolism, bile and calculation of nutrient deficiency. 


 

Biliopancreatic diversion (BPD)

 

 
A large part of the stomach is removed. The quantity of food is restricted, as well as the production of stomach acid. The stomach pouch that remains is connected directly to the final segment of the small intestine, completely skewing the other parties. A channel remains common in which the digestive juices pancreatic and bile mixed up before entering the colon. The loss of weight is because the majority of calories and nutrients are targeted to the colon where there are absorbed. A variation of Biliopancreatic diversion (BPD) preserves a large portion of the stomach intact and part of the duodenum.
