CPAP = continuous positive airway pressure; SD = standard deviation; BMI = body mass index; CAOD = coronary artery obstructive disease; OSAS = obstructive sleep apnea syndrome; PFT = pulmonary function test; FVC = forced vital capacity; FEV1 = forced expiratory volume in 1 second; VC = vital capacity; IC = inspiratory capacity; ERV = expiratory reserve volume; ASA = American Society of Anesthesiologists; PCA = patient-controlled analgesics; HS = length of postoperative hospital stay; IQR = interquartile range.

Seventy patients were evaluated for the severity of OSAS by polysomnography.

A total of 69 patients were evaluated for PFT. Four of 54 patients were evaluated for FVC, FEV1 and FEV1/FVC.

Postoperative complications: left gastric artery pseudoaneurysm (n=2, 2.7%), small bowel obstruction (n=2, 2.7%), marginal ulcer bleeding (n=2, 2.7%), fever of unknown origin (n=1, 1.4%), postoperative acute tubular necrosis of kidney (n=1, 1.4%), anastomosis site stricture (n=1, 1.4%) and anastomosis site perforation (n=1, 1.4%).
