In-laboratory polysomnography (PSG) is considered the gold standard for diagnosing obstructive sleep apnea (OSA). Our study aimed to compare whether home polygraphy (PG) could provide comparable diagnostic accuracy to PSG before bariatric surgery in a real-life cohort and to determine whether home PG is associated with a higher incidence of complications.
In a retrospective study, we compared 400 patients who performed home PG or laboratory PSG between January 2017 and March 2020. All patients included had to be incident cases and had to have undergone bariatric surgery after the sleep test.
Among the participants, 215 underwent PSG, while 185 underwent PG. Demographic characteristics such as age, sex, BMI, and Epworth sleepiness score were similar between groups. The apnea-hypopnea index was significantly lower in the PG group (21 ± 20 events/h) compared to the PSG group (29 ± 28 events/h) (p < 0.001). The proportion of patients treated with positive airway pressure was comparable between the two groups. Following bariatric surgery, the duration of hospitalization and the incidence of postoperative complications did not differ significantly between the two groups.
Our findings suggest that before bariatric surgery, home PG could identify patients requiring positive airway pressure as equivalent to in-laboratory PSG, without increasing postoperative complications.
实验室多导睡眠图（PSG）被认为是诊断阻塞性睡眠呼吸暂停（OSA）的金标准。我们的研究旨在比较在现实生活队列中，减肥手术前家庭多导睡眠监测（PG）能否提供与PSG相当的诊断准确性，并确定家庭PG是否与更高的并发症发生率相关。
在一项回顾性研究中，我们比较了2017年1月至2020年3月期间进行家庭PG或实验室PSG的400例患者。纳入的所有患者均为新发病例，且在睡眠测试后接受了减肥手术。
参与者中，215例接受了PSG，185例接受了PG。两组间年龄、性别、BMI和爱泼华嗜睡量表评分等人口统计学特征相似。PG组的呼吸暂停低通气指数（21±20次/小时）显著低于PSG组（29±28次/小时）（p<0.001）。两组间接受气道正压治疗的患者比例相当。减肥手术后，两组间住院时间和术后并发症发生率无显著差异。
我们的研究结果表明，在减肥手术前，家庭PG能够识别出需要气道正压治疗的患者，与实验室PSG效果相当，且不会增加术后并发症。
