Outcome Measures

Primary Outcomes (2)

  • Effective Apnea Hypopnea Index

    The Effective Apnea Hypopnea Index (AHI) is the actual frequency of apneas and hypopneas per hour that the patient is exposed to. It is calculated as the AHI while on CPAP times the proportion of sleep time that CPAP was used plus the AHI off CPAP times the proportion of sleep time that CPAP is not used.

    9 months

  • Epworth Sleepiness Score

    The Epworth Sleepiness Scale results in scores ranging from 0-24, where scores of 0-10 indicate normal levels of sleepiness while 11-24 indicate excessive daytime sleepiness.

Procedure: Laparoscopic Gastric Banding

Continuous Positive Airway Pressure

ACTIVE COMPARATOR
Procedure: Continuous Positive Airway Pressure

Interventions

Those randomized to surgery would meet with the bariatric surgeon and the dietitian during the 3 month weight management period and based on insurance requirements, would undergo LGB surgery after 3 months of weight management. PAP therapy would be utilized for the 3 week peri-operative period (1 week prior to 2 weeks post-operatively) given evidence that this might reduce peri-operative respiratory complications. Routine surgical follow-up will occur 2 weeks post-operatively and then every 4-6 weeks to assess weight loss trajectory and adjust the band as needed.

Laparoscopic Gastric Banding

Participants randomized to the CPAP arm will undergo a CPAP titration within 2 weeks of enrollment unless a split-night study was already performed as part of their diagnostic polysomnogram (PSG) providing a reliable CPAP therapeutic pressure. As soon as an appropriate pressure is identified, CPAP therapy will begin with routinely scheduled follow-up visits to maximize CPAP adherence. All participants will be offered a 12 month supervised weight loss program in addition to OSA-specific therapy.
