Weight loss (bariatric) surgery is a life-saving treatment and changed the lives of morbidly obese patients who have not had success with traditional weight loss under medical supervision, such as strategies for change in eating habits, exercise and / or medication. It works by physically limiting the amount of food patients can eat and / or interrupt the process of digestion. Adipose tissue is not removed.
Severe obesity, usually as a weight of at least 100 pounds more than the ideal height for his age defined and is the second leading cause of preventable death in the United States. Around 18 million people in the U.S. suffer. This condition has been increasing in the United States, the number of procedures for weight loss also of 16,000 in 1990 to 180,000 in spring 2005 has increased, according to the American Society for Bariatric Surgery.This module explains that bariatric surgery may be appropriate, what to expect in the process and what is in the immediate postoperative period and long term.
Bariatric surgery induces weight loss by physically restricting the amount of food patients can eat and/or by interrupting the digestive process. It does not work by removing fatty tissue from the body.
Bariatric procedures fall into three categories:
• Restrictive surgeries, such as the Lap-Band® procedure, the vertical banded gastroplasty (“stomach stapling”), and the sleeve gastrectomy, physically limit the amount of food a patient can consume by reducing the size of the stomach or the amount it can expand.
• Combined procedures, including Roux-en-Y gastric bypass, do the same but also surgically reroute the digestive tract so that food actually bypasses most of the stomach. Combined procedures make up 80 to 85 percent of all bariatric surgeries performed in the United States.
• Malabsorptive procedures, such as biliopancreatic diversion bypass, do not affect food intake but instead limit the absorption of calories and nutrients from food by creating a bypass around a significant length of intestine.
For very ill obese patients, for whom the restrictive or combined surgeries might be too risky, the procedures are sometimes broken down into two smaller operations.
Some bariatric procedures are performed with traditional “open surgery,” necessitating a large abdominal incision, while others can be performed laparoscopically, meaning that they are conducted by making small incisions in the abdomen and inserting tiny instruments through those incisions.
During laparoscopic surgery, a telescope and camera project the image of the patient’s organs and the surgical instruments onto a video monitor. Because of the minimally invasive nature of laparoscopic surgery, time in the hospital, postoperative pain, and infection risks are markedly reduced in comparison to open surgery but not entirely eliminated.
In some cases, bariatric surgery that may typically be performed laparoscopically is inadvisable because of a patient’s weight, body shape, or previous surgeries. In those instances, open surgery can usually be performed instead.
To determine which, if any, procedure may be appropriate, bariatric surgeons must weigh the risks versus the benefits for each patient. The patients as well as their doctors should also consider which procedures the surgeons have the most experience performing.
