Here is your sleeve weight loss surgery article.

With obesity continuing to increase in many Western countries bariatric surgery is becoming an everyday type of surgery in a large number of medical facilities.

The sleeve gastrectomy is a restrictive type of surgery in which about 85% of the stomach is surgically removed leaving a cylindrical or sleeve shaped stomach with a vastly reduced capacity ranging from about 60 to 150 cc. Unlike many other forms of obesity surgery, the outlet valve and the nerves to the stomach are left intact and, although the stomach is severely reduced in size, its function is preserved. Again, unlike other forms of surgery like the time honored Roux-en-Y gastric bypass the sleeve gastrectomy cannot be reversed.

As the new stomach continues to function as normal there are far fewer restrictions when it comes to the foods which patients can eat following surgery, thought the amount of food consumed will be very noticeably reduced. This is seen by many patients as one of the main advantages of the vertical sleeve gastrectomy, as is the fact that removing most of the stomach also results in the virtual elimination of the hormones that are produced in the stomach and which stimulate hunger.

Perhaps the biggest advantage of the vertical gastrectomy is to be found in the fact that it does not bypass the intestines so that patients do not therefore suffer the complications of bypass including vitamin deficiency, intestinal obstruction, anemia and protein deficiency. It also means that it is a suitable type of surgery for people who are already suffering from Crohn's disease, anemia and various other conditions that would place them at risk for surgery involving intestinal bypass.

Lastly, it is one of the few forms of surgery which can be done laparoscopically in patients who are extremely overweight.

Possibly the principal disadvantage of the vertical gastrectomy is to be found in the fact that it does not always produce the which people want and can produce weight regain in the long term. This is of course true of any type of solely restrictive surgery though it is possibly particularly true in the case of the vertical gastrectomy.

As the operation requires stapling of the stomach patients do run the risk from leakage and other complications which are specifically related to stapling. Furthermore, as with any surgery, patients are at risk from additional complications including small bowel obstruction, post-surgical bleeding, pneumonia and even death. The risk of encountering these complications is nonetheless very small and varies from about 0.5 and 1%. Having said this, the risk of death as a result of this type of surgery at around 0 .25% is very small indeed.

Generally speaking the vertical sleeve gastrectomy is most suited to patients who are either extremely overweight or whose medical condition rules out other forms of surgery. In the case of the former the vertical sleeve gastrectomy would normally form the first of a two-part plan, with follow-up surgery being done once the patient's weight has fallen enough to allow other forms of surgery to be performed.
