Background: Banded Roux-en-Y gastric bypass is a further modified standard RYGB which was designed in a view to achieve greater weight loss and avoid or diminish weight regain in the long term. There is conflicting evidence as whether the banded RYGB is better than standard non-banded type and lack of literature in this part of south India made us to conduct this study. Objectives: To compare the outcomes in terms of mean weight loss, % excess weight loss, significant weight loss and resolution of comorbidities among banded and non-banded Roux-En-Y Gastric Bypass groups at 1 year of post-operative period. Methodology: A longitudinal observational study was carried out at two tertiary care hospitals in the Department of Laparoscopic and Bariatric Surgery, Bangalore in 109 morbidly obese patients who underwent standard non-banded RYGB and banded RYGB during January 2012 to December 2015 and were followed up till 2016 for a period of 1 year. The 1-year total weight loss, excess weight loss (%) and significant excess weight loss were comparatively analyzed using independent t test, Mann Whitney, Fisher’s exact test and Chi-square test wherever, required. A P value of <0.05 was taken as statistically significant Results: Among 109 patients who underwent RYGB, 67.9% underwent non-banded RYGB and 32.1% banded RYGB. The mean age of study subjects was 43.91yrs with a standard deviation of 11.71yrs and females predominated the study and both the groups were comparable in all the socio-demographic characteristics except for age and presence of hypertension. Mean Total Weight loss, Median Excess Weight loss, >50.0% BMI loss, resolution of comorbidities were nearly similar and not significantly different in both the study groups. (P>0.05) Conclusion: Both banded and non-banded RYGB were equally effective in reducing excess weight loss and resolution of comorbidities at the end of 1 year of post-operative period. On comparing with other literatures, highlights the requirement of long term follow up.
