BMI ≥ 70: A Multi-Center Institutional Experience of the Safety and Efficacy of Metabolic and Bariatric Surgery Intervention.

PURPOSE

With the escalating prevalence of obesity, healthcare providers are increasingly managing patients with a body mass index (BMI) exceeding 70. The aim of this study was to describe the perioperative experiences of this demographic group at two institutions.

METHODS

An analysis encompassing 84 patients presenting with BMI ≥ 70 kg/m from two institutions was conducted. Data included patient demographics, 30-day postoperative outcomes, and weight-loss at different intervals (30 days, 6 months, 1 year). Additionally, rates of emergency department (ED) utilization, readmission, and reoperation in the first postoperative year were examined.

RESULTS

Most patients were black (66.7%) and female (86.9%) with a mean age of 41.7 years. The majority underwent laparoscopic sleeve gastrectomy (SG, 88.1%). Patients exhibited a marked decrease in BMI (7.84% at 30 days, 20.13% at 6 months, and 26.83% at 1 year). Average length of stay was comparable across procedure (F(3,80) = 0.016, p = .997). While 30-day complications were minimal (0.7%), 14.4% of patients experienced ED visits within 30 days, escalating to 19.6% by six months and 25% at 1 year. Readmission and reoperation rates at 1 year were 6.45% and 4.83%, respectively.

CONCLUSION

With global obesity rates rising, clinicians are being challenged to care for patients with BMI ≥ 70 kg/m. Analysis of two institutions demonstrated low rates of 30-days complications but increased readmission rates and ED utilization in this patient population. Despite increased resource utilization, the study suggests that BMI ≥ 70 kg/m alone should not be a deterrent for surgery, emphasizing the need for nuanced care in this expanding demographic.
