Abstract

Purpose: With the global increase in life expectancy and the subsequent impaired quality of life in older obese adults, modalities such as bariatric surgery become crucial to help lose excess weight. This study was conducted to evaluate the effectiveness and safety of one anastomosis gastric bypass (OAGB) in patients 65 years old and above.

Materials and methods: This retrospective cohort study was conducted on 61 patients with severe obesity aged ≥ 65 years through Iran National Obesity Surgery Database. The patients had undergone OAGB and were followed up for 12 to 60 months. The required data was extracted through national database.

Results: Mean age and BMI of the patients were 67.62 ± 2.03 years and 46.42 ± 5.46 kg/m2, respectively. Regarding gender, 90.1% of the participants were female. Mean operative time and length of hospital stay were 41.37 ± 13.91 min and 1.16 ± 0.61 days, respectively. Five patients (8.19%) required ICU admission. The changes in %TWL after 3, 6, 12, 24, 36, 48, and 60 month follow-up was 18.62%, 25.51%, 32.84%, 35.86%, 38.49%, 31.41%, and 29.52%, respectively. The resolution of gastroesophageal reflux disease, diabetes mellitus, dyslipidemia, obstructive sleep apnea, and hypertension after 24 month was about 100%, 65%, 73.33%, 100%, and 76%, respectively. The postoperative early and late complications were 6.53% and 11.46%, respectively. We did not find significant difference in above results between two age groups of 65-70 and > 70 years.

Conclusions: OAGB can be a good choice in older obese adults because of its shorter operative time, higher potency, and low complication rate.
