Comparison of laparoscopic sleeve gastrectomy to laparoscopic Roux-en-Y gastric bypass for morbid obesity in a military institution.
Surg Obes Relat Dis. 2014 Mar-Apr; 10(2):269-76.SO

Abstract

BACKGROUND

Laparoscopic sleeve gastrectomy (LSG) is gaining acceptance in the bariatric community as a definitive weight loss procedure; however, longitudinal data remain limited. The objective of this study was to compare weight loss results of LSG with laparoscopic Roux-en-Y gastric bypass (LRYGB) up to 5 years postoperatively using anthropometric measurements.

METHODS

Prospectively collected bariatric database at the Naval Medical Center San Diego was retrospectively reviewed from 2005-2011 . Anthropometric factors, including weight and hip circumference were measured during standard yearly follow-up appointments. Surgical outcomes were tested by the Student t test and demographic variables by Fisher's exact and Wilcoxon rank-sum tests.

RESULTS

Follow-up was achieved in 147/226 LRYGB versus 130/208 LSG at year 1, 92/195 versus 81/151 at year 2, 64/145 versus 50/100 at year 3, 32/81 versus 18/54 at year 4, and 12/42 versus 14/15 at year 5. The excess weight loss (EWL) for LRYGB versus LSG was 72% versus 64.7% at 1 year (P = .002), 71.3% versus 65.5% at 2 years (P = .113), and 68.3% versus 57.4% at 5 years (P = .252), respectively. Similarly, the body mass index (BMI) decrease was statistically significant at 1 year (P = .001) but not on subsequent annual visits. Mean percent body adiposity index (BAI) decrease was 28.4% for LRYGB versus 26.8% for LSG at 1 year (P = .679) and 21.8% versus 29.8% at 2 years (P = .134), respectively. Weight loss measured in terms of %EWL and decrease in BMI and BAI did not show significance between LRYGB and LSG 2 years after surgery.

CONCLUSION

Our study provides similar long-term weight loss between LSG and LRYGB, and therefore, LSG is a viable option as a definitive bariatric procedure.
