Abstract:

Objective

To evaluate the effectiveness of laparoscopic sleeve gastrectomy (LSG) in obese patients obstructive sleep apnea and hypopnea syndrome (OSAHS). To provide an evidence-based basis for LSG treatment of obesity OSAHS.

Methods

Computer search databases from January 1980 to June 2022: PubMed, Embase, Cochrane Library, Web of Science, CNKI, Wanfang Database, VIP Database, Chinese BioMedical Literature Database. We searched for high-quality clinical studies on obesity OSAHS patients, LSG as an intervention, and postoperative polysomnography monitoring as an outcome indicator, strictly according to the inclusion and exclusion criteria. Data extraction and assessment of publication bias were performed for the included literature. The postoperative apnea-hypopnea index (AHI), minimum SpO2 during sleep, sleep efficiency, and Epworth Sleepiness Scale (ESS) was used to objectively evaluate the severity of sleep apnea and hypoventilation. Body Mass Index (BMI) and neck circumference were used as indicators to objectively evaluate weight loss. They were compared with their preoperative baseline data. Forest plots showed a large heterogeneity among studies, which was mainly attributed to the small number of included literature and the fact that they were all owned before and after controlled studies.

Results

A total of 7 studies were included in 316 patients with obesity OSAHS and with a high risk of migration. The results of this meta-analysis showed that LSG has significant and statistically significant improvements in all of the following indicators, BMI (MD=13.36, 95%CI: [11.55, 15.18], P<0.05), apnea hypoventilation index (AHI)(MD=24.54, 95%CI: [15.44, 33.73], P<0.05) , minimum oxygen saturation (MinSaO2) (MD=–13.95, 95%CI: [–22.61, –5.29], P<0.05) , rapid eye movement (REM) sleep as a percentage of total sleep time (MD=–2.70, 95% CI: [–4.37, –1.02], P<0.05), Epworth Sleepiness Scale score (ESS) (MD=5.17, 95%CI: [1.99, 8.35], P<0.05) and neck circumference (MD=5.65, 95%CI: [4.52, 6.78], P<0.05).There was no significant effect on sleep efficiency (MD=–6.30, 95%CI:[–12.88, 0.28], P=0.06).

Conclusions

LSG has significant therapeutic effects on obesity and OSAHS in obese OSAHS patients, but further observation is needed for the long-term efficacy of this operation.
