Introduction: Aging 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.
Objectives: To evaluate the efficacy and safety of laparoscopic bariatric surgery in patients over 70 years of age.
Methods: A 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.
Results: Fourteen 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.
Conclusions: This systematic review suggests that laparoscopic bariatric surgery is an effective and safe treatment for patients over 70 years of age.
