Abstract | BACKGROUND: OBJECTIVES: To evaluate the prevalence and phenotypes of patients with persistent moderate to severe OSA after bariatric surgery. SETTING:
Obesity Center Amsterdam, Amsterdam, the Netherlands. METHODS: Patients who underwent a laparoscopic Roux-en-Y gastric bypass, had a preoperative apnea-hypopnea index (AHI)≥15/hr, and of whom a follow-up AHI/hr was available were included. RESULTS: Out of 437 patients, 205 underwent pre- and postoperative polysomnography; 232 (53.1%) were lost to follow-up. Median AHI was 32.3/hr (range, 15-138) and mean body mass index was 46 (standard deviation 7.2) kg/m2. A postoperative AHI<15/hr was achieved in 152 patients (74.1%), whereas 53 (25.9%) still had moderate or severe disease 8.6 (standard deviation 4.8) months postoperatively. Predictive factors for persistent moderate to severe disease were age≥50 years, preoperative AHI≥30/hr, excess weight loss (EWL)<60%, and hypertension (area under the curve: .772). CONCLUSION: After bariatric surgery, around three quarters of the moderate to severe OSA patients had no or mild OSA, whereas one quarter (25.9%) still had moderate to severe OSA. Age≥50 years, preoperative AHI≥30/hr, EWL<60%, and hypertension were predictive factors for this persistent postoperative AHI≥15/hr.
