Abstract
Background: Long-term results and factors affecting outcomes of vacuum bell therapy for pectus excavatum are relatively unknown.
Methods: We conducted a retrospective study on patients (<18y) treated with vacuum bell therapy between May 2008 and October 2021. Primary outcome was treatment success; secondary outcomes were analysis of daily time spent on treatment, treatment duration, complications, long-term follow-up, treatment for patients awaiting a Nuss procedure, treatment for female patients, and factors affecting outcomes.
Results: Of 259 patients treated with vacuum bell therapy, 18.9% (n = 49/259) were still being treated, 17.4% (n = 45/259) were lost to follow-up and 63.7% (n = 165/259) completed treatment, with a 52.1% (n = 86/165) success rate. Median follow-up was 64.0 months (interquartile range 48.0-87.0). More time spent daily on vacuum bell therapy, total treatment duration, and overnight use led to a higher success rate (P = 0.002, P < 0.001, P < 0.001 resp.). Complications (22.8%, n = 59/259) were minor, recurrence occurred in 2.3% (n = 2/86) of patients. Of the patients treated while awaiting a Nuss procedure, 26.7% (n = 4/15) no longer required the Nuss procedure. Breast growth made 39.3% (n = 11/28) of female patients quit treatment. Deeper deformities (P = 0.02, P = 0.009), flexible chest wall (P = 0.007) and symptomatic pectus excavatum (P = 0.02) resulted in lower success rates.
Conclusions: Vacuum bell therapy is successful in up to 52.1% of patients. Overnight vacuum bell use and treatment while awaiting a Nuss procedure should be encouraged. Older patients with a stiff chest wall can be successfully treated with prolonged treatment. For female patients watchful waiting or early treatment, to prevent challenges during breast growth, is preferred.
期刊介绍:
The journal presents original contributions as well as a complete international abstracts section and other special departments to provide the most current source of information and references in pediatric surgery. The journal is based on the need to improve the surgical care of infants and children, not only through advances in physiology, pathology and surgical techniques, but also by attention to the unique emotional and physical needs of the young patient.
