Background The perceived benefits of Roux‐en‐Y laparoscopic gastric bypass ( LRYGB ) surgery in the ≥60s are regarded as being significantly less than in the younger population. This study examined a New Zealand population who underwent LRYGB and analysed the mortality rate, complications and postoperative weight loss. Methods This was a retrospective cohort study of patients who underwent LRYGB over a 12‐year period and had attended up to 1 year of follow‐up clinic. The study population was from a single centre in New Zealand. Results A total of 1362 patients were eligible. Demographic analysis showed the <60 to have 83% female majority, mean age of 43 years and a mean body mass index of 46. The ≥60 group had a 76% female majority, mean age of 63 years and a mean body mass index of 45. The % excess weight loss, % weight loss and weight loss at 1 year all showed a significant difference. Analysis of the % excess weight loss at 1 year in the ≥60s showed a mean of 79% and a median of 78% (95% confidence interval: 69%, 85%). In the <60s the mean was 84% and the median 84% (95% confidence interval: 83%, 85%). Comparison between the groups showed a significant difference (Kruskal‐Wallis test, P = 0.0064). The complication frequency of the groups was not significantly different (chi‐square test, P = 0.7605). Conclusion LRYGB is an effective weight loss operation in the <60s and ≥60s. LRYGB is safe, with a low complication rate and 30‐day postoperative mortality rate. LRYGB should not be restricted on the basis of age alone.
