Abstract

Background: The impact of age on complications following bariatric surgery remains unclear. Research is therefore warranted among previously unstudied populations of bariatric surgery patients. The aim of the current study was to assess the impact of age on postoperative complications following bariatric surgery in Saudi Arabia. Methods: This retrospective study included 301 patients who underwent bariatric surgery between January 2011 and July 2016. Patients were classified into three groups according to age:,25 years; 25–36 years; and .36 years. Primary outcomes were determined by identifying the number of complications reported during a period of 180 days. The negative binomial model was used to assess the relationship between age and the high rate of postoperative complications following adjustment for confounding variables. Results: The incidence of overall complications was 10.1% in the,25-year age group, 15% in the 25–36-year age group, and 24.2% in the .36-year age group. After adjusting for confounding variables, it was discovered that the risk of postoperative complications increases with age. The risk was higher in the .36-year age group than in the .25-year age group [adjusted relative rate (aRR) ¼ 2.35; 95% confidence interval (CI) ¼ 1.046–5.290; p ¼ 0.039]. Diabetes (aRR ¼ 3.27), adjustable gastric bands (aRR ¼ 3.40), and a more lengthy hospital stay (aRR ¼ 1.23) were associated with increased rates of postoperative complications. Conclusion: Age is independently associated with a high rate of postoperative complications following bariatric surgery. The results showed that patients with diabetes, those using adjustable gastric bands, and those with longer length of hospital stay had significantly higher incidence of postoperative complications. These findings indicate the need for risk stratification tools to evaluate patients as candidates for bariatric surgery and to use as a guide for identifying optimal preoperative factors.
