ABSTRACT Background: Bariatric surgery is still controversial in elderly patients with severe obesity. Most publications focus on safety and early clinical outcomes. Food tolerance and nutritional postoperative risk is unknown for this population. Methods: Thirty-six elderly patients with severe obesity were recruited for an open-label randomized trial from September 2017 to May 2019 comparing laparoscopic sleeve gastrectomy (LSG) to Roux-en-Y Gastric Bypass (LRYGB). Food tolerance was accessed by Quality of Alimentation (QoA) questionnaire and data on weight loss, body composition, and nutritional risk were collected between 6 and 24 months after surgery. Results: Comparing LSG to LRYGB patients, the latter had higher total weight loss (22% vs 31%, P=0.01) and excess weight loss (53% vs 68%, P=0.01). Food tolerance to eight food groups was similar between groups (14 vs 15 points, P=0.270), as Suter score (23 vs 25, P=0.238). Daily protein intake was below recommendation in both groups (40 vs 51 g/d, P=0.105). Nutritional risk, evaluated through Standardized Phase Angle (-1.48 vs -1.99, P=0.027), was worse for LRYGB group. Conclusion: Food tolerance and adequacy of food consumption were similar in both groups. LRYGB patients had higher nutritional risk.
