简要总结
This study aims to evaluate the efficacy of an endoluminal gastric plication using an endoluminal-suturing device to improve severe OSAS in patients with a BMI above or equal to 28 kg/m² until 34.9kg/m².
详细描述
Obesity is one of the most critical public health burdens worldwide. Its prevalence is increasing, as well as its comorbidities. The main comorbidity of obesity on the respiratory system is the obstructive sleep apnea syndrome (OSAS). The prevalence of OSAS in the obese population is around 45%. OSAS increased cardiovascular risk and decreased quality of life. The most alterable risk factor of OSAS is obesity. Therefore, weight loss is the cornerstone of the treatment. There is some evidence of the efficacy of weight loss surgery (lap band, sleeve gastrectomy, biliary pancreatic deviation, duodenal switch, and Roux-and-Y-gastric bypass) to improve OSAS. Current recommendations suggest bariatric surgery management for patients with a BMI > 35kg/m2 and OSAS. However, most studies have limited scientific value (retrospective observational trials), and the follow-up of patients is limited, mainly due to patients' inadequate compliance. Moreover, until now, there is no reliable predictor for the percentage of reduction of AHI caused by weight loss. On the other hand, there is no approved treatment in patients presenting a BMI between 28 kg/m² to 34.9kg/m² and OSAS.
Endoscopic endoluminal approaches to address obesity have become an important topic of interest over the past decade. Endomina® (Endo Tools Therapeutics, Gosselies, Belgium) is a novel restrictive endoluminal approach. This new procedure permitted a weight loss of 29 % on average sustained at one year. This technique was not yet evaluated in patients with 28 kg/m2 ≤ BMI ≤ 34.9/m2 to improve OSAS.
The current feasibility study aims to evaluate the efficacy of an endoluminal gastric plication using an endoluminal-suturing device to improve severe OSAS in patients with above or equal to 28 kg/m², BMI until 34.9kg/m².
