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.

Obstructive Sleep

Over the past few decades, the incidence of obesity has been steadily rising in the United States. The Centers for Disease Control and Prevention estimates greater than 40% of the US adult population is obese. Rising obesity rates are also increasing among children and adolescents as well, with nearly one in five children and adolescents considered obese. As a result, surgeons today face the challenge of caring for an increasing number of morbidly obese patients, and this trend is expected to worsen over time. This review covers preoperative evaluation, obesity-related comorbidities, respiratory insufficiency, anesthesia in patients with respiratory insufficiency, intraoperative management, postoperative management, complications of gastric surgery for obesity, diabetes mellitus, wound care, and other obesity-related diseases. Figures show impaired pulmonary function in the morbidly obese improved significantly after weight loss induced by bariatric surgery, significant improvement in mean pulmonary arterial pressure in 18 patients, 3 to 9 months after gastric surgery-induced weight loss of 42% ± 19% of excess weight, and a chronic venous stasis ulcer present for several years in a morbidly obese patient. The tables list evaluation and treatment of obstructive sleep apnea, and indications for extended postoperative chemoprophylaxis for venous thromboembolism in morbidly obese patients. This review contains 3 highly rendered figures, 2 tables, and 46 references Keywords: morbid obesity, obesity, metabolic surgery, venous thromboembolism chemoprophylaxis, Obstructive Sleep Apnea
