Mini Gastric Bypass Surgery is bairiatric procedure that has gained popularity in recent years. The procedure is used as a great tool to get rid of almost all excess weight in patients with morbid obesity. The procedure itself was developed in 1997 by Dr. Robert Rutledge and was identified as a good alternative to the traditional gastric bypass surgery. The purpose of both the mini gastric bypass surgery and the traditional gastric surgery is to significantly reduce the size of the stomach in order to limit the amount of food an individual can consume. During the procedure the digestive system is generally altered which thus helps in reducing the amount of calories and nutrients the body can absorb.

Generally the procedure can be termed as restrictive and malabsorptive. The restrictive part is what entails the reduction of the stomach thus restricting the amount of food an individual can eat. The malabsorptive is alteration of the digestive tract whereby the surgeon bypasses the up to 6 feet of the intestines thus reducing the amount of food that can be absorbed.

Reasons for the Creation of the Mini Gastric Bypass Surgery 

The development of the mini gastric bypass surgery was inspired by the need to reduce the operating time, improve the procedure as well as reduce the complications that are associated with bariatric procedures. Although the traditional gastric bypass procedure yields the same results as the mini gastric bypass procedure, it takes longer times to perform the operation and is often very complex while it is also associated with various complications. The mini gastric bypass surgery has reduced the complication rates significantly compared to the traditional gastric bypass procedure.

The procedure  

Mini gastric is a minimally invasive procedure which means that it is conducted laparoscopically where the surgeon makes a few small incisions through which he passes the essential instruments that are required to conduct the operation inside the internal organs. The surgeon is able to perform the surgery by viewing the internal organs on monitor to which images are sent by the laparoscope which is a tiny camera passed through one of the incisions.

This procedure is conducted after the patient is fully prepared after having been given all the information about the entire procedure, the likely complications which are few as well after conducting some very important tests to ensure that the patient qualifies for the procedure.

The procedure starts by the surgeon making narrow tube which is different from the pouch that is create when conducting the standard or traditional gastric bypass surgery. The stomach is then separated with a stapler and the large part of the stomach is thus separated from the oesophagus meaning that it will no longer receive food. Basically, your stomach now becomes smaller and with a tube like shape.

Next the small intestine are then bypasses between 2 to 7 feet of length. The remainder of the small intestines is then connected with the new tube-shaped stomach. The bypassed part of the intestines is where most of the absorption of food takes place. Thus once it has been bypassed, one consumes food, it will be going directly to the tube shaped stomach and the directly to the remaining part of the small intestines. This ensures that the patient does not eat too much food due to the reduced stomach size and also a lot of calories and nutrients are not absorbed into the body since the small intestines especially the duodenum has been bypassed.

Mini gastric bypass surgery can lead to effective loss of excess weight especially when it is combined with other lifelong lifestyle changes. This can work very well form people with extreme obesity which is known as morbid obesity. Such people should healthy lifestyle changes in order to ensure that the procedure is very effective and that they remain with healthy weight for the rest of their lives.
