Comparative study of outcomes following laparoscopic Roux-en-Y gastric bypass and sleeve gastrectomy in morbidly obese patients: A case control study

Figure 1 Impact of bariatric surgery on body mass index over two years follow-up: There was no significant difference in body mass index preoperatively (P = 0. 11) and at 1 year post-op (P = 0.175). At 2 years follow-up however, patients who had undergone LSG had significantly higher BMI (P = 0.038) compared with those who had undergone LRYGB. Mean BMI were compared using Student’s t test. LSG: Laparoscopic sleeve gastrectomy; LRYGB: Laparoscopic Roux-en-Y gastric bypass; BMI: Body mass index.

Figure 2 Impact of bariatric surgery on percentage excess weight loss over two years follow-up: There was no significant difference in percentage excess weight loss at 1 year post-op (P = 0. 36). At 2 years follow-up however, patients who had undergone LRYGB had significantly greater excess weight loss (P = 0.044) compared with those who had undergone LSG. %EWL were compared using Student’s t test. LSG: Laparoscopic sleeve gastrectomy; LRYGB: Laparoscopic Roux-en-Y gastric bypass; %EWL: Percentage excess weight loss.
