Abstract
BACKGROUND: Even though risks are higher and long-term results may be less favorable, the elderly obese can still benefit from bariatric surgery. Whether the higher surgical risk is worth the benefits is yet to be determined. MATERIALS AND METHODS: We reviewed our database and identified all patients aged 65 or older who underwent sleeve gastrectomy between May 2010 and November 2015. We documented patient demographics, obesity-related comorbidities, body mass index (BMI) before and after the procedure, percent excess weight loss, comorbidity improvement or resolution, length of follow-up, postoperative complications, re-operations, and length of hospital stay. We compared our study group to a control group of sleeve gastrectomy patients under the age of 65. RESULTS: Sixty-six patients (mean age 67.6 ± 2.6 years) underwent laparoscopic sleeve gastrectomy. Patients achieved an average of 53.5% excess BMI loss (EBMIL) after 21 months of follow-up. EBMIL was inferior to that achieved by the control group (EBMIL 77.3%, p < 0.0001). Elderly patients showed significant improvement or resolution in all obesity-related comorbidities. Complication and re-operation rates were similar between the 2 groups. CONCLUSION: In an elderly population, laparoscopic sleeve gastrectomy is safe and effective, yet weight loss outcomes are more modest when compared to a younger surgical population. Carefully selected elderly patients can benefit from bariatric surgery.
