Introduction: Only a few studies have studied bariatric surgery in the elderly population.
Methods: Data from the Ontario Bariatric Registry between 2010-2015 was used for this retrospective study to determine outcomes of bariatric surgery in the elderly population, compared with the population under 65 years old, with 3-year follow-up.
Results: 6420 patients underwent RYGB or SG, and completed at least 1-year follow-up. Of these, 140 patients (2%) were in the elderly cohort (BMI 48.4, age 66 yo, 70% female), with 101 patients undergoing RYGB (72.1%) and 39 undergoing SG (27.9%). At baseline, the elderly group had more hypertension (80.0 % vs 44.9%), diabetes (86.0% vs 31.1%) and hyperlipidemia (86.6% vs 32.7%) than the younger group (BMI 49.5, age 45 yo, 84% female). Outcomes at 3-year follow-up are as follows:
| Under 65 | 65 and over | p-value | |

16.4 (5.6) 16.1 (5.8) |

Conclusions: Gastric bypass and sleeve gastrectomy have similar overall mortality and morbidity rates for elderly patients, when compared to the younger patients. The elderly group may have an increased thromboembolic risk. Further study is needed to evaluate this finding.
