In an era of rising obesity and an aging population, there are conflicting data regarding outcomes of laparoscopic weight loss surgery in older Americans. The aim of this study was to characterize the short-term outcomes of laparoscopic weight loss surgery in the elderly. The ACS NSQIP database was queried for obese patients aged ≥40 years undergoing laparoscopic Roux-en-Y gastric bypass or sleeve gastrectomy. Patients were subdivided into age groups: 40 to 49, 50 to 59, 60 to 64, 65 to 69, and ≥70 years, and compared with univariate and multivariate analyses. Fifty-three thousand five hundred thirty-three patients were identified. Roux-en-Y gastric bypass was performed in 57.5 per cent of cases and was more common than sleeve gastrectomy in all age groups ( < 0.05). Comorbidities increased significantly with increasing age. There was an increase in minor (4.6% 9.1%; < 0.0001) and major complications (2.2% 6.3%; < 0.0001), and 30-day mortality (0.1% 0.5%; = 0.0001) between the 40 to 49 and ≥70 years age groups. Increased age was independently associated with major complications. Mortality also increased with age. Older patients undergoing laparoscopic weight loss surgery have increased morbidity and mortality. When controlling for comorbidities, increases in age continued to impact major and minor complications and mortality.
