Influence of continuous positive airway pressure on postoperative leakage in bariatric surgery.
Obstructive sleep apnea (OSA) affects two third of morbidly obese individuals undergoing bariatric surgery. Perioperative usage of continuous positive airway pressure (CPAP) is advised for moderately and severe OSA to avoid respiratory failure and cardiac events. CPAP increases the air pressure in the upper airway, but also may elevate the air pressure in the esophagus and stomach. Concern exists that this predisposes to mechanical stress resulting in suture or staple line disruption (further referred to as suture line disruption). ⋯ Postoperative CPAP does not appear to increase the risk of suture line disruption in bariatric surgery. CPAP is recommended in all patients with moderate or severe OSA who undergo bariatric surgery.
