Weight Loss Clinical Trial
Official title:
Effect of Laparoscopic Sleeve Gastrectomy and Liraglutide on Glucose Homeostasis and Intrapancreatic Fat in Obese Patients
Investigators postulate that the metabolic effects of LSG would be augmented with the use of liraglutide leading to additional excess weight loss, improved glucose homeostasis, decreased intrapancreatic and intrahepatic fat than either of them individually. However there are no studies till date which have evaluated the combined effects of two modalities of weight loss on the above mentioned parameters. This study plans to compare the effects of liraglutide in post- LSG obese patients in a placebo controlled design.
Various studies have shown that bariatric surgery is associated with significant durable
weight loss with associated improvement in obesity related comorbidities and quality of life.
The degree of effect on obesity related comorbidities depends on the bariatric surgery
approach, typically classified as restrictive and/or malabsorptive effect. Data from
International Federation for the Surgery of Obesity and Metabolic Diseases states that most
common surgical procedures being performed are Roux-en-Y gastric bypass (45%), sleeve
gastrectomy(37%), adjustable gastric banding(10%) and biliopancreatic division with or
without duodenal switch(2.5%)5. . LSG is technically a simpler procedure compared to RYGB
with lesser operative and long term nutritional complications. The mechanism for weight loss
in laparoscopic sleeve gastrectomy is gastric restriction and possible changes in gut
hormones resulting from higher level of GLP-1, and lower levels of ghrelin, as a consequence
of resection of gastric fundus.
Therefore,investigators postulate that the metabolic effects of LSG would be augmented with
the use of liraglutide leading to additional excess weight loss, improved glucose
homeostasis, decreased intrapancreatic and intrahepatic fat than either of them individually.
However there are no studies till date which have evaluated the combined effects of two
modalities of weight loss on the above mentioned parameters. This study plans to compare the
effects of liraglutide in post- LSG obese participants in a placebo controlled design.
