Abstract

The increasing rate of obesity and life expectancy will lead to increasing numbers of bariatric procedures in the elderly. We aim to report the early (≤ 30 days) adverse events of One-Anastomosis Gastric Bypass (OAGB) in this patient population. Assuta Bariatric Centers in Israel. Retrospective review of perioperative OAGB outcomes between elderly group (≥ 65 years) and non-elderly group (18–64 years) at high-volume bariatric centers between January 2017–December 2021. Operative time, length of stay (LOS), and overall ≤ 30 days complication rates, as ranked by the Clavien–Dindo Classification (CDC) were compared. There were 6618 patients (non-elderly group) and 104 (elderly group) who underwent OAGB. Gender and preoperative BMI were comparable between the two age groups. The elderly group had significantly higher rate of ischemic heart disease and chronic renal failure. The number of patients with LOS ≥ 3 days was significantly higher in the elderly group [19.4% (n = 20) vs. 6.6% (n = 331), respectively; p < 0.001]. The total early adverse events were higher in the elderly group with no statistical significance [7.7% (n = 8) vs. 3.8% (n = 250), respectively; p = 0.062]. The rate of minor and major adverse events and reoperation rate was comparable between the two groups. The rate of readmissions was significantly higher in the elderly group 5.8% (n = 6) vs. 1.9% (n = 124), respectively p = 0.015. There was 0.06% mortality (n = 2) in the non-elderly group. OAGB is a relatively safe metabolic and bariatric surgery for elderly obese patients with early (≤ 30 days) morbidity rates similar to the non-elderly population.
