Cost-effectiveness and safety of continuous pulse oximetry for management of undiagnosed obstructive sleep apnea in bariatric surgery: a nationwide cohort study.

Background: Undetected obstructive sleep apnea (OSA) is highly prevalent in patients undergoing bariatric surgery and increases perioperative risks. Screening for OSA using preoperative polygraphy (PG) with subsequent continuous positive airway pressure (CPAP) is costly and time-consuming. Postoperative continuous pulse oximetry (CPOX) is less invasive, and is hypothesized to be a safe and cost-effective alternative.

Cross-sectional E-survey on the Incidence of Pre- and Postoperative Chronic Pain in Bariatric Surgery.

Background: To assess the prevalence, incidence, location, and behavior of chronic pre- and postoperative pain in bariatric surgery, and the use of analgesics.

Methods: A cross-sectional e-survey was conducted on 3928 post-bariatric patients and four-time points for pain assessment were evaluated: preoperative, on the ward, day 1 at home postoperatively, and present time (at the time of the e-survey). A numerical rating scale (NRS) was used to assess the level of pain (0 to 10).

Evaluation of CPAP adherence in bariatric patients diagnosed with obstructive sleep apnea: outcomes of a multicenter cohort study.

Purpose: Obstructive sleep apnea (OSA) is highly prevalent but mostly undiagnosed in obese patients scheduled for bariatric surgery. To prevent cardiopulmonary complications, many clinics perform preoperative OSA screening. Consequently, adequate adherence to continuous positive airway pressure (CPAP) therapy is essential but challenging.

The Benefits of Banded over Non-banded Roux-en-Y Gastric Bypass in Patients with Morbid Obesity: a Multi-center Study.

Background: Roux-en-Y gastric bypass (RYGB) has proven to be an effective treatment for obesity with excellent long-term results, even though weight regain can occur. A method to improve the results of RYGB and minimize chance of weight regain is banded RYGB. Better sustained weight loss is also related to higher remission of comorbidities.
