0999 A dramatic response to sleeve gastrectomy in a patient with severe obstructive sleep apnea

Abstract Introduction Obesity is a well-established major, yet modifiable risk factor for the development of obstructive sleep apnea (OSA). Weight loss has consistently been associated with improvement in OSA severity. Here, we present case patient morbid obesity and severe who underwent bariatric surgery, which resulted complete resolution apnea. Report case(s) A 31-year-old woman history (body mass index (BMI) 54kg/m²) diabetes mellitus was seen disorders clinic symptoms loud snoring, gasp awakenings, fragmented sleep, excessive daytime sleepiness an Epworth score (ESS) 18. Polysomnography (PSG) demonstrated apnea-hypopnea (AHI) 129/hr, mean arterial oxygen saturation (SaO2) 85%, nadir SaO2 52%. Continuous positive airway pressure (CPAP) prescribed but never started. One year later, she returned requesting treatment as part evaluation surgery. split-night PSG re-demonstrated AHI 60/hr 51% 54% total time spent less than 88%, good response to CPAP 14cmH2O residual 4/hr. started excellent adherence on follow up. Three years lapsed before clinic. During this time, had undergone sleeve gastrectomy successful at losing 156lbs (achieving BMI 31kg/m²). She reported snoring ESS 1. stopped using six months after surgery wished be re-evaluated OSA. Repeat showed no evidence 1/hr 91%. Conclusion Bariatric considered most effective indicated patients 35kg/m² or greater comorbid Although observational randomized studies weight reduction have shown severity post-operatively even cure some cases, few exhibit extreme here, This serves important reminder that should priority when managing excess body weight.
