Abstract Background Pectus excavatum, the most common chest wall deformity, is frequently treated with Nuss procedure. Here we will describe non-invasive procedure and analyze the variables associated vacuum bell therapy for patients with pectus excavatum. Methods Retrospective case–control study in a single center between July 2018 and February 2022, including patients with pectus excavatum treated with vacuum bell. Follow-up was continued to September 2022. The Haller index and Correction index was calculated before and after treatment to analysis the effectiveness of vacuum bell therapy. Results There were 98 patients enrolled in the treatment group, with 72 available for analysis, and the follow-up period ranged from 1.1 to 4.4 years (mean 3.3 years). When analyzing with the Haller Index, 18 patients (25.0%) showed excellent correction, 13 patients (18.1%) achieved good correction, and 4 patients (5.6%) had fair correction. The remaining patients had a poor outcome. Characteristics predicting a non-poor prognosis included initial age ≤ 11 years (OR = 3.94, p = 0.013) and patients with use over 24 consecutive months (OR = 3.95, p = 0.013). A total of 9 patients (12.5%) achieved a CI reduction below 10. Patients who started vacuum bell therapy at age > 11 had significantly less change compared to those who started at age ≤ 11 (P

Abstract Background Controversy remains despite several studies have discussed the role of bariatric surgery in improving male’s sexual function. This study aims to evaluate the efficacy of bariatric surgery in promoting male’s erectile function. Methods PubMed, EMbase, The Cochrane Library, CNKI and Clinical Trails.gov were searched from database inception to May 2019. The language of publication was limited in English. The International Index of Erectile Function (IIEF) score and Brief Male Sexual Function Inventory (BSFI) score were set as the primary outcome. Results Eleven studies with a total of 370 patients were enrolled in this meta-analysis. The results showed significant improvement in the IIEF score (erectile function: MD = 5.33, 95% CI 4.12–6.54; intercourse satisfaction: MD = 2.57, 95% CI 1.19–3.94; orgasmic function: MD = 0.50, 95%CI 0.60–0.94; overall satisfaction: MD = 1.67, 95% CI 0.78–2.56; sexual desire: MD = 1.27, 95% CI 0.61–1.93; total erectile function: MD = 7.21, 95% CI 4.33–10.10) and the BSFI score (erection: MD =2.53, 95% CI 2.39–2.67; ejaculation: MD = 1.40, 95% CI 1.28–1.51; desire: MD =1.40, 95% CI 1.32–1.49; problem assessment: MD = 2.20, 95% CI 2.06–2.34; sexual satisfaction: MD = 0.70, 95% CI 0.60–0.76) in obese individuals after bariatric surgery. Conclusions This systematic review and meta-analysis indicated that bariatric surgery could be effective in promoting males’s sexual function for obese individuals.
