Abstract
Until recently, weight loss in older obese people was feared because of ensuing muscle loss and frailty. Facing overall increasing longevity, high rates of obesity in older individuals (age ≥ 65 years) and a growing recognition of the health and functional cost of the number of obesity years, abetted by evidence that intentional weight loss in older obese people is safe, this approach is gradually, but not unanimously, being replaced by more active principles. Lifestyle interventions that include reduced but sufficient energy intake, age-adequate protein and micronutrient intake, coupled with aerobic and resistance exercise tailored to personal limitations, can induce weight loss with improvement in frailty indices. Sustained weight loss at this age can prevent or ameliorate diabetes. More active steps are controversial. The use of weight loss medications, particularly glucagon-like peptide-1 analogs (liraglutide as the first example), provides an additional treatment tier. Its safety and cardiovascular health benefits have been convincingly shown in older obese patients with type 2 diabetes mellitus. In our opinion, this option should not be denied to obese individuals with prediabetes or other obesity-related comorbidities based on age. Finally, many reports now provide evidence that bariatric surgery can be safely performed in older people as the last treatment tier. Risk-benefit issues should be considered with extreme care and disclosed to candidates. The selection process requires good presurgical functional status, individualized consideration of the sequels of obesity, and reliance on centers that are highly experienced in the surgical procedure as well as short-term and long-term subsequent comprehensive care and support.

Association of metabolic-bariatric surgery with long-term survival in adults with and without diabetes: a one-stage meta-analysis of matched cohort and prospective controlled studies with 174 772 participants. Lancet 2021; 397:1830-1841. [PMID: 33965067 DOI: 10.1016/s0140-6736(21)00591-2] [Citation(s) in RCA: 224] [Impact Index Per Article: 74.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2020] [Revised: 02/08/2021] [Accepted: 03/01/2021] [Indexed: 12/12/2022]
Abstract
BACKGROUND Metabolic-bariatric surgery delivers substantial weight loss and can induce remission or improvement of obesity-related risks and complications. However, more robust estimates of its effect on long-term mortality and life expectancy-especially stratified by pre-existing diabetes status-are needed to guide policy and facilitate patient counselling. We compared long-term survival outcomes of severely obese patients who received metabolic-bariatric surgery versus usual care. METHODS We did a prespecified one-stage meta-analysis using patient-level survival data reconstructed from prospective controlled trials and high-quality matched cohort studies. We searched PubMed, Scopus, and MEDLINE (via Ovid) for randomised trials, prospective controlled studies, and matched cohort studies comparing all-cause mortality after metabolic-bariatric surgery versus non-surgical management of obesity published between inception and Feb 3, 2021. We also searched grey literature by reviewing bibliographies of included studies as well as review articles. Shared-frailty (ie, random-effects) and stratified Cox models were fitted to compare all-cause mortality of adults with obesity who underwent metabolic-bariatric surgery compared with matched controls who received usual care, taking into account clustering of participants at the study level. We also computed numbers needed to treat, and extrapolated life expectancy using Gompertz proportional-hazards modelling. The study protocol is prospectively registered on PROSPERO, number CRD42020218472. FINDINGS Among 1470 articles identified, 16 matched cohort studies and one prospective controlled trial were included in the analysis. 7712 deaths occurred during 1·2 million patient-years. In the overall population consisting 174 772 participants, metabolic-bariatric surgery was associated with a reduction in hazard rate of death of 49·2% (95% CI 46·3-51·9, p<0·0001) and median life expectancy was 6·1 years (95% CI 5·2-6·9) longer than usual care. In subgroup analyses, both individuals with (hazard ratio 0·409, 95% CI 0·370-0·453, p<0·0001) or without (0·704, 0·588-0·843, p<0·0001) baseline diabetes who underwent metabolic-bariatric surgery had lower rates of all-cause mortality, but the treatment effect was considerably greater for those with diabetes (between-subgroup I2 95·7%, p<0·0001). Median life expectancy was 9·3 years (95% CI 7·1-11·8) longer for patients with diabetes in the surgery group than the non-surgical group, whereas the life expectancy gain was 5·1 years (2·0-9·3) for patients without diabetes. The numbers needed to treat to prevent one additional death over a 10-year time frame were 8·4 (95% CI 7·8-9·1) for adults with diabetes and 29·8 (21·2-56·8) for those without diabetes. Treatment effects did not appear to differ between gastric bypass, banding, and sleeve gastrectomy (I2 3·4%, p=0·36). By leveraging the results of this meta-analysis and other published data, we estimated that every 1·0% increase in metabolic-bariatric surgery utilisation rates among the global pool of metabolic-bariatric candidates with and without diabetes could yield 5·1 million and 6·6 million potential life-years, respectively. INTERPRETATION Among adults with obesity, metabolic-bariatric surgery is associated with substantially lower all-cause mortality rates and longer life expectancy than usual obesity management. Survival benefits are much more pronounced for people with pre-existing diabetes than those without. FUNDING None.

Abstract
To evaluate, mid-term outcomes between elderly patients (EP, i.e., age > 60 years old) and young patients (YP, i.e., age < = 60 years old) who underwent laparoscopic bariatric surgery. Studies comparing EP versus YP for bariatric surgery published until April 2020 were selected and submitted to a systematic review and meta-analysis. After LSG, overall morbidity and specific post-operative complication rates (i.e., leak, abscess, hemorrhage, and reoperation) were significantly more frequent in EP compared with those in YP. Surgical outcomes were similar between EP and YP after LRYGB. Both procedures achieved weight loss, but it was statistically greater in YP compared with that in EP. In summary, this meta-analysis suggests that laparoscopic bariatric surgery is a safe and effective treatment in EP compared with that in YP.

Abstract
BACKGROUND Obesity is a common disease in the elderly population, and bariatric surgery is the most effective intervention to achieve significant and sustainable weight loss. Many bariatric programs have established an arbitrary cutoff at the age of 60 to 65 years. The aim of this study was to evaluate the safety and short-term outcomes of Roux-en-Y gastric bypass (RYGB) in patients older than 60 years. PATIENTS AND METHODS We conducted a retrospective cohort study of patients who underwent RYGB from 2004 to 2019 in a single center. Logistic and linear multivariate regressions were made to compare complications and short-term outcomes between patients aged > 60 years and < 60 years. The statistical significance was set at p ≤ 0.05. RESULTS From 849 patients who underwent a primary RYGB, 57 were > 60 years of age. Overall, early and late complications were similar in both groups, except for unexpected intensive care unit (ICU) admission which was more frequent in the > 60 years group. Excess body weight loss (%EWL) and percentage total weight loss (%TWL) at 1 year in patients > 60 years old were 76.6 ± 21.8% and 30.73 ± 6.8%, respectively. Figures for the same parameters in the control group were 81.7 ± 19.9% (p = 0.09) and 34.3 ± 7.2 (p = 0.001), respectively. CONCLUSIONS In our experience, an age > 60 is not related to higher rates of overall early and late complications after RYGB. Comorbidity remission rates are similar to those in younger patients. Elderly patients had lower total weight loss at 1 year, but the %EWL was similar in both groups.

Abstract
BACKGROUND To provide greater insight into bariatric surgery outcomes in aging patients, we compared changes in body weight, body composition, obesity-related comorbidities, and nutritional status between older and younger subjects. METHODS We analyzed data collected between January 2004 and December 2014 from our prospective bariatric cohort. Older patients (OP, ≥ 60 years at the time of surgery, n = 93; 66% Roux-en-Y gastric bypass, 34% sleeve gastrectomy) were compared with younger patients (YP, < 60 years, n = 186), matched 1:2 on sex, body mass index, diabetes, and surgical procedure. Body composition was assessed by dual-energy X-ray absorptiometry. RESULTS Weight loss and excess weight loss at 12 months were lower in OP vs. YP (mean ± SD, 30.1 ± 10.1 vs. 34.1 ± 11.9 kg, 60.6 ± 21.2 vs. 66.8 ± 23.4%, respectively, p < 0.05 for both). Both lean body mass and fat mass loss were lower in OP vs. YP (8.4 ± 3.4 vs. 9.2 ± 9.0 kg, 19.4 ± 8.7 vs. 21.9 ± 9.1 kg, respectively, p < 0.05). The remission rate for type 2 diabetes was significantly lower in OP vs. YP (24 vs. 45%), as well as improvement in hypertension (14 vs. 46%), dyslipidemia (27 vs. 47%), and knee pain. There was no difference in micronutrient deficiencies between groups. CONCLUSIONS These data indicate that although bariatric surgery is not as effective for weight loss in older as in younger subjects, it is a safe option regarding a comprehensive set of nutritional variables which enables significant improvement in obesity-related outcomes.

Abstract
BACKGROUND People are living longer than they were expected to 2 decades ago. Increased life expectancy and reduced mortality encompasses a simultaneous increase in the number of older adults with obesity that entails an increase of co-morbidities, such as diabetes, hypertension, cancer, and many other diseases. The aim of our study was to compare the outcomes of bariatric surgery in patients age ≥65 in comparison with younger patients. METHODS This retrospective study compares bariatric surgeries performed in a private institution between the years 2013 and 2015. The study included 9044 patients divided into an older group (451 patients) and the younger group (8593 patients). RESULTS In the younger group, bariatric surgery is distributed as follows: 77.68% sleeve gastrectomy, 12.72% gastric banding, 9.27% gastric bypass, and .33% duodenal switch or biliopancreatic diversion; in the older group: 70.51% sleeve gastrectomy, 15.08% gastric bypass, 13.97% gastric band, and .44% biliopancreatic diversion. In the control group 550 cases (6.4%) underwent revisional surgery; 64 cases (14.10%) underwent revision in the older group. Older patients lost less excess weight than younger patients (72.44% versus 86.11%, respectively). Older patients presented higher rates of complications (8.42% versus 5.59%), co-morbidities (77.60% versus 55.45%), and revisions (1.33% versus .77%). There was no statistical difference in hospital stay between older group and control group (2.27 versus 2.23, respectively). When performing a Clavien-Dindo classification, we demonstrated significant differences in class 3B and 4A and no differences in other classes. Two deaths occurred in the control group. Diabetes, fatty liver, and sleep apnea have been improved or remitted in >90% of patients in both groups, hypertension and hyperlipidemia by >80%, and hyperuricemia and ischemic heart disease were improved or resolved in >70% of the patients CONCLUSIONS: Bariatric surgery in the elderly has more complications, but it can still be considered safe.
