There is a strong relationship between obesity and the development of obstructive sleep apnea (OSA). Respectively, bariatric surgery is often touted as the most effective option for treating obesity and its comorbidities, including OSA. Nevertheless, there remains paucity of data in the literature of the comparison of all the specific types of bariatric surgery themselves. In an effort to answer this question, a systematic review was performed, to determine, of the available bariatric procedures [Roux-en-Y gastric bypass, laparoscopic sleeve gastrectomy, or biliopancreatic diversion (BPD)], which procedures were the most efficacious in the treatment of OSA. A total of 69 studies with 13,900 patients were included. All the procedures achieved profound effects on OSA, as over 75 % of patients saw at least an improvement in their sleep apnea. BPD was the most successful procedure in improving or resolving OSA, with laparoscopic adjustable gastric banding being the least. In conclusion, bariatric surgery is a definitive treatment for obstructive sleep apnea, regardless of the specific type.
