+Obesity is a global pandemic!
Age-standardised prevalence of overweight and obesity and obesity alone, ages ≥20 years, by sex, 1980–2013Ng M, Fleming T, Robinson M et al. Lancet 2014;384:766-781
+We are not only the second in World’s GDP, but also…
+Obesity cause 3.4 Millions death in 2010
+Prevalence of type 2 DM and We have near 1,400,000,000 people!
11.9% 9.3%
+The BMI threshold for Bariatric Surgery is now: 27.5
IFSO-APC Consensus Statements 2011
BMI ≥27.5 + DM or metabolic syndrome
1991 NIH Consensus Statement
BMI > 40
BMI > 35-40 + severe comorbids
Bariatric Surgery needs YOU!
+Laparoscopic Sleeve Gastrectomy
Significant weight loss
DM remission rate comparable with gastric bypass
Relative Safer
Shorter learning Curve
+LSG is increasing performed worldwide in just last few years!
+Laparoscopic sleeve gastrectomy as an initial weight-loss procedure for high-risk patients with morbid obesity.

+BMI Is Predictive of Higher In-hospital Mortality in Patients Undergoing Laparoscopic Gastric Bypass but Not Laparoscopic Sleeve Gastrectomy or Gastric Banding
For gastric bypass, there was an increased of in-hospital mortality (0.01 and 0.02 vs 0.34%; P< 0.01) and major complications (0.93 and 0.99 vs 2.6%; P< 0.01) in the BMI 60kg/m2 or greater group.

+LSG as a Revisonal Procedure after Adjustable Gastric Band?
Similar EWL % as compared with revision to LRYGB.
Ranging from 23% to 74%
Higher complications rate as primary procedures
All the included studies are cohort studies.
