Objective Evidence

Background: Lifestyle modification is the mainstay therapy for obese patients with obstructive sleep apnea (OSA). However, most of these patients are unable to lose the necessary weight, and bariatric surgery (BS) has been proven to be an effective modality in selected cases. Objective: To provide objective evidence that BS can improve OSA severity. Materials and Methods: A prospective study was conducted in super morbidly obese patients (body mass index [BMI] greater than 40 kg/m² or BMI greater than 35 kg/m² with uncontrolled comorbidities) scheduled for BS. Polysomnography (PSG) was performed for preoperative assessment and OSA was treated accordingly. After successful surgery, patients were invited to perform follow-up PSG at 3, 6, and 12 months. Results: Twenty-four patients with a mean age of 35.0±14.0 years were enrolled. After a mean follow-up period of 7.8±3.4 months, the mean BMI, Epworth sleepiness scale (ESS), and apnea-hypopnea index (AHI) significantly decreased from 51.6±8.7 to 38.2±6.8 kg/m² (p<0.001), from 8.7±5.9 to 4.7±3.5 (p=0.003), and from 87.6±38.9 to 28.5±21.5 events/hour (p<0.001), respectively. Conclusion: BS was shown to dramatically improve clinical and sleep parameters in super morbidly obese patients. Keywords: Morbid obesity, Bariatric surgery, Obstructive sleep apnea (OSA)

Obstructive Sleep

Obstructive sleep apnea (OSA) is highly prevalent in morbidly obese patients, although it is surprisingly underdiagnosed and undertreated. OSA can increase the risk of serious and life-threating complications in the perioperative period of bariatric surgery. Nevertheless, this potential risk can be minimized with adequate preoperative screening and perioperative management. The perioperative management of patients with OSA will affect the preparation for surgery, airway management, anesthetic selection, and monitoring. This chapter discusses and presents the best evidences available for the management of patients with OSA in order to decrease both the prevalence of undiagnosed patients and the morbidity associated with bariatric surgery.
