Abstract
Introduction: The presence of (OSAS) is an independent risk factor for postoperative complications in bariatric surgery
Objetive: To evaluate which factors might influence the postoperative complications of patients undergoing bariatric surgery, and its possible relationship with the diagnosis of OSAS.
Methods: A prospective study that included patients with OSA diagnostic who underwent Bariatric Surgery in the period between October 2006 to December 2015. Demographic data, body mass index (BMI), presence of OSAS, use of CPAP and postoperative complications were analysed.
Results: A total of 361 patients have been studied, with an average age of 40 ± 10.66 years old. 69% were women. The average BMI was 45.47±8.34. Postsurgical complications occurred in 54 patients (15%). Among them, 21 required reoperation (5.8%), and only one patient died because of respiratory failure. 211 (58%) were diagnosed with OSAS, indicating CPAP (continuous positive airway pressure) therapy in 57%. 29 (13.7%) had complications, of which 14 (48%) had a severe polygraphy, 13.8% moderate and 38.2% mild. 18 (62%) CPAP patients suffered complications. The average BMI was 46.54±6, with the 70.4% of complications in patients with BMI≥45, with p = 0.055 (OR= 1 39; CI 0.98-1.81).
Conclusions: BMI seems to have a direct relationship with the occurrence of complications in patients undergoing surgery, hence the importance of dietary treatments for weight loss before surgery. Patients with CPAP had more complications, perhaps since their degree of OSA is more severe and have higher obesity and more co-morbidities, as well as influence their withdrawal in the postoperative period.
