Background: Obesity is a worldwide epidemic and exercise supplemented with pharmacotherapy has poor long-term results; thus, bariatric
surgery is the mainstay therapy for morbid obesity. But reduction in weight and BMI after bariatric surgery is not the same and mainly depends
on the type of surgery performed.
Aim and objective: To study the comparative efficacy among three bariatric surgeries viz. Laparoscopic gastric imbrication (LGI), laparoscopic sleeve
gastrectomy (LSG), and laparoscopic Roux-en-Y gastric bypass (LRYGB) in morbid obese patients in relation to weight loss and reduction in BMI.
Study design: Prospective study.
Materials and methods: Total of 40 morbid obese patients underwent different types of laparoscopic bariatric surgery and were followed for
1 year. Reduction in weight and BMI after 1 year was correlated with the type of bariatric surgery performed.
Statistical analysis: Paired t-test, analysis of variance (ANOVA), Bonferroni.

Results: Patients undergone LGI, LSG, and LRYGB had a preoperative mean weight/BMI of 105.33 kg/41.07 kg m , 104.07 kg/42.76 kg m , and

105.8 kg/43.27 kg m , respectively; and postoperative mean weight/BMI after 1 year was 87.4 kg/34.08 kg m , 81.07 kg/33.32 kg m , and

81.2 kg/33.18 kg m , respectively. On applying ANOVA and Bonferroni, LSG and LRYGB group had greater weight loss and reduction in BMI
as compared to LGI group.
Conclusion: LSG and LRYGB are statistically better in weight and BMI reduction in obese as compared to LGI. Although weight and BMI reduction
was more in LRYGB as compared to LSG, it was not statistically significant.
Keywords: BMI reduction, LGI, LRYGB, LSG, Weight loss.
