Sleeve gastrectomy or vertical sleeve gastrectomy, is a surgical weight-loss procedure, typically performed laparoscopically, in which approximately 75 - 85% of the stomach is removed, [1] [2] along the greater curvature, [3] which leaves a cylindrical, or "sleeve"-shaped stomach the size of a banana.
[23] [25] [27] [28] Weight loss reported from high volume community practices that have both expertise in ESG and robust longitudinal aftercare programs with dietitians have shown even greater outcomes, with total body weight loss approaching 30% and excess weight loss of 66% at one year.
After five years, Roux-en-Y resulted in greater weight loss (26% compared to 19% for sleeve gastrectomy) and a 25% lower rate of diabetes relapse. However, Roux-en-Y patients had a higher likelihood of hospitalization and additional abdominal surgeries compared to sleeve gastrectomy. [65]
The duodenal switch (DS) procedure, also known as a gastric reduction duodenal switch (GRDS), is a weight loss surgery procedure that is composed of a restrictive and a malabsorptive aspect. The restrictive portion of the surgery involves removing approximately 70% of the stomach (along the greater curvature) and most of the duodenum .
The SADI-S is a single anastomosis bariatric surgery. It is different from the classic duodenal switch, the gastric bypass (RNY) or sleeve gastrectomy.It is a type of bariatric surgery carried out to lose weight and to mitigate various metabolic issues including type 2 diabetes, dislipidemia, metabolic syndrome, and polycystic ovary syndrome.
Often the prior procedure still lends itself to a revision to become a Roux-en-Y gastric bypass. It may be performed laparoscopically, and the average recovery time is approximately two weeks. [8] The weight loss success rate after Roux-en-Y gastric bypass revision surgery is generally excellent. [9]
The MGB has been suggested as an alternative to the Roux-en-Y procedure due to the simplicity of its construction and is becoming more and more popular because of low risk of complications and good sustained weight loss. It has been estimated that 15.4% of weight loss surgery in Asia is now performed via the MGB technique. [journal 6]
About 30% of those who undergo VBG achieve normal weight, and about 80% achieve some degree of weight loss. Most studies have suggested that 10 years after surgery, only 10% of patients maintain a minimum weight loss of at least 50% of their total excess weight at the time of their initial surgery. Some patients regain weight.
