Bariatric surgery has seen a sharp rise in India in the last decade. India is one of the 10 most obese nations of the world, ranking second in number of type 2 diabetics.
To evaluate clinical outcomes of bariatric surgery after 3 years of follow-up in terms of weight loss, co-morbidity resolution, complaints of gastroesophageal reflux disease and weight regain.
All patients who underwent bariatric surgery from January to December 2013 with a minimum follow-up of 3 years were included in the study. Their demographic, preoperative, and postoperative data were prospectively maintained on Microsoft Office Excel and analyzed statistically.
One hundred seventy-eight patients (157 lap. sleeve gastrectomy and 21 patients lap. RYGB) completed 3 years of follow-up. In the LSG group, patients had a pre-operative BMI 44.8 ± 8.33 kg/sq. m (mean ± S.D.) and excess body weight 52.3 ± 23.0 kg. In the RYGB group, pre-operative BMI was 42.7 ± 8.82 kg/sq. m and excess body weight 45 ± 18.7 kg. In the LSG group, % excess weight loss (EWL) at 1 year was 87.6 ± 24.4% and 3 years was 71.8 ± 26.7%. In the RYGB group, % EWL at 1 year was 97.2 ± 27.3% and at 3 years was 85.8 ± 25.3%. Diabetes resolution was seen in 32 (80%) in LSG group and 11 (91.7%) in RYGB group (Figs. 1, 2, 3, and 4).
Our study reflects that there is no statistically significant difference between outcomes of sleeve gastrectomy and Roux-en-Y gastric bypass surgery in terms of weight loss and diabetes resolution at 3 years.
