Obesity is a global health problem that also affects older adults. In Chile, as in most of the developing countries, more than half of older adults are overweight or obese, and bariatric surgery may be riskier for this group. The aim of this study is to compare our experience in patients over 60 years of age with a control group to determine associated surgical morbidity and mortality.
Case-control study of bariatric surgeries performed between 2006 and 2017 in our institution. Patients aged ≥ 60 years for the case group versus control group for patients ≤ 50 years selected randomly, matched by body mass index, type 2 diabetes, hypertension, dyslipidemia, surgical technique, and gender (ratio 1:2). Primary endpoint was surgical morbidity, 30-day readmission, and mortality.
Seventy-two patients in case group were matched with 144 patients in control group. Surgical complications rate was the same for both groups. No differences were observed in the conversion to open surgery rate or 30-day readmission rate. There was no mortality in this series.
In this case-control study, being elderly does not increase the risk of morbidity and mortality associated with bariatric surgery.
肥胖是一个全球性的健康问题，也影响到老年人。在智利，与大多数发展中国家一样，超过一半的老年人超重或肥胖，而对于这一人群，减重手术的风险可能更大。本研究旨在比较我们在 60 岁以上患者中的经验与对照组，以确定相关的手术发病率和死亡率。
本研究为回顾性病例对照研究，纳入了 2006 年至 2017 年期间在我院进行的减重手术患者。以≥60 岁为病例组，以≤50 岁为对照组，随机选择，通过体重指数、2 型糖尿病、高血压、血脂异常、手术技术和性别（1:2）进行匹配。主要终点是手术发病率、30 天再入院率和死亡率。
病例组有 72 例患者与对照组的 144 例患者相匹配。两组的手术并发症发生率相同。两组之间的中转开腹率或 30 天再入院率没有差异。本研究系列中没有死亡病例。
在这项病例对照研究中，年龄较大并不会增加减重手术相关发病率和死亡率的风险。
