Abstract

Aim: To investigate the effect of weight loss and metabolic improvement after laparoscopic sleeve gastrectomy (LSG) in older adults aged 65 years or over compared with younger adults in a retrospective analysis.

Methods: The J-SMART study database of 322 Japanese individuals with body mass index (BMI) ≥32 kg/m² who underwent LSG between 2011 and 2014 at 10 centers accredited by the Japanese Society for Treatment of Obesity were analyzed. The subjects were classified into two groups: ≥65 age group (range, 65-76 years; n = 25) and <65 age group (range, 22-64 years; n = 297). Clinical parameters were compared between the groups.

Results: Baseline data for the ≥65 vs. <65 age groups were: median age 67 years vs. 45 years; weight 92.7 kg vs. 114.4 kg; BMI 40.0 kg/m² vs. 41.9 kg/m²; and HbA1c 6.8% vs. 6.5%. The ≥65 age group had significantly lower preoperative weight, BMI, estimated glomerular filtration rate, and ABCD score, but higher visceral fat area and prevalence of diabetes, hypertension, and obstructive sleep apnea (OSAS). Weight was significantly reduced in both groups throughout 5 years post-LSG, though total weight loss at 2 years was lower in the ≥65 age group (28.0%) than in the <65 group (30.0%). Remission rates of diabetes, hypertension, OSAS, and joint disorders 2 years after LSG showed no significant differences, except for dyslipidemia.

Conclusion: LSG may be an efficacious option for improving obesity-related health problems in older adults. However, postoperative safety and complications were not evaluated in this study and further research is needed.

期刊介绍： Diabetology International, the official journal of the Japan Diabetes Society, publishes original research articles about experimental research and clinical studies in diabetes and related areas. The journal also presents editorials, reviews, commentaries, reports of expert committees, and case reports on any aspect of diabetes. Diabetology International welcomes submissions from researchers, clinicians, and health professionals throughout the world who are interested in research, treatment, and care of patients with diabetes. All manuscripts are peer-reviewed to assure that high-quality information in the field of diabetes is made available to readers. Manuscripts are reviewed with due respect for the author''s confidentiality. At the same time, reviewers also have rights to confidentiality, which are respected by the editors. The journal follows a single-blind review procedure, where the reviewers are aware of the names and affiliations of the authors, but the reviewer reports provided to authors are anonymous. Single-blind peer review is the traditional model of peer review that many reviewers are comfortable with, and it facilitates a dispassionate critique of a manuscript.
