Efficacy and safety of laparoscopic bariatric surgery in patients of 70 years and older: A systematic review and meta-analysis

IntroductionAging population and growing obesity prevalence are two major public health issues. Bariatric surgery has been shown to be both safe and effective, but its role in the treatment of the elderly remains controversial.ObjectivesTo evaluate the efficacy and safety of laparoscopic bariatric surgery in patients over 70 years of age.MethodsA systematic review and assessment of the literature was performed in November-December 2023. Inclusion criteria gathered studies of elderly (age >= 70 years old) who underwent laparoscopic bariatric surgery. The data extraction focused on weight loss, obesity-related diseases, and complications.ResultsFourteen retrospective studies were included, involving 3923 septuagenarians (female, 69.70%). One year after the surgery, the mean excess weight loss was 54.66%. At last follow-up, the improvement in obesity-related diseases was regarded as 50% diagnosed with diabetes, 36% with hypertension, 50% with reflux, 36% with sleep apnea, and 25% with hyperlipidemia. The overall postoperative major morbidity and mortality were about 2% and 1%, respectively.ConclusionsThis systematic review suggests that laparoscopic bariatric surgery is an effective and safe treatment for patients over 70 years of age.
