Bariatric Surgery

Obesity Surgery is the surgical alteration of stomach or intestines or both, to bring about weight loss.

Obesity Surgery is the surgical alteration of stomach or intestines or both, to bring about weight loss. In the US, approximately 160,000 bariatric operations are performed each year. The development of safe laparoscopic approach has made this operation more popular. Indications Suitable for bariatric surgery are patients if they have a body mass index (BMI)> 40 kg / m2 or> 35 kg / m2 plus a serious complication (eg. As diabetes, hypertension, obstructive sleep apnea, high-risk lipid profile) have, they have an acceptable operative risk, they are well informed and motivated with them all reasonable non-surgical methods for weight loss and to address the obesity-associated complications have been exhausted. Clinical Calculator: Body Mass Index (Quetelet’s index) Although studies have shown that surgery in patients with a BMI of 30-35 leads to diabetes remission, there are hardly any long-term data. In patients with a lower BMI, the use of bariatric surgery is controversial. Contraindications include: uncontrolled psychiatric illness such as depression, current drug or alcohol abuse, a cancer that is not understood in remission, another life-threatening disease, the inability to compliance in terms of nutritional requirements, including lifelong vitamin substitution (if indicated ). Procedures in the US the most common methods are: Roux-en-Y gastric bypass (Roux-en-Y gastric bypass, RYGB) gastric tube (gastrectomy Sleeve, SG) Adjustable gastric banding (adjustable gastric banding, GTC) Most procedures laparoscopically what less pain and a shorter recovery time is compared to open surgery. Traditionally, the bariatric surgery is considered restrictive and / or malabsorptive regarding the alleged weight loss mechanism. However, other factors appear to contribute to weight loss. Thus, the Roux-en-Y gastric bypass lead (traditionally known as malabsorptive classified) and sleeve gastrectomy (traditionally classified as restrictive) to metabolic both or promote hormonal changes, saturation and weight loss, as well as (for further hormonal changes such. B. increase insulin secretion [incretin]) that contribute to a rapid remission of diabetes. After a Roux-en-Y gastric bypass surgery (in particular) or a gastric tube formation to increase the levels of gastrointestinal hormones such as glucagon-like peptide-1 (GLP-1) and peptide YY (PYY) and thus may contribute to satiety, weight loss and diabetes remission. Increased insulin sensitivity is shown immediately after surgery, before significant weight loss occurs, suggesting that neurohormonal factors play an important role in the remission of diabetes. Roux-en-Y gastric bypass surgery, the Roux-en-Y gastric bypass surgery (RYGB) accounts for about 80% of bariatric procedures in the United States and is performed laparoscopically in general. A small portion of the proximal stomach is separated from the residue, whereby a stomach pouch of <30 ml arises. In this way, the food bypass part of the stomach and small intestine, where they are normally absorbed, which in turn leads to a reduction of the quantities of food and calories. The bag is connected to the proximal jejunum, and the opening between the two is so narrow that the rate of gastric emptying is inhibited. The segment of the small intestine, which is connected to the bypass stomach, is attached to the distal small intestine. This leads to the fact that bile acids and pancreatic enzymes mix with the gastrointestinal contents so limited and malabsorption and malnutrition. The Roux-en-Y gastric bypass surgery is particularly effective in the treatment of diabetes; remission rates reach up to 62% after six years. In patients with instead gehabter gastric bypass surgery operation, the consumption of fatty and sugary foods greatly dumping syndrome, the so-called trigger. the symptoms include dizziness, sweating, nausea, abdominal pain and diarrhea. The dumping syndrome can inhibit the consumption of such foods by negative conditioning.
