For precise therapy to right pectus excavatum (PE), conservative treatment with all the vacuum bell (VB) was introduced a lot more than 10 years ago along with surgical repair. Preliminary benefits using the VB had been encouraging. We report on our 13-year experience using the VB treatment including the intraoperative use for the duration of the Nuss procedure and present some technical innovations.

A VB using a patient-activated hand pump is used to create a vacuum at the anterior chest wall. 3 diverse sizes of vacuum bells, at the same time as a model fitted for young girls, exist. The suitable size is selected in line with the person patient’s age and ventral surface. The device needs to be utilised at home for a minimum of 30 minutes (twice per day), and might be employed as much as a maximum of many hours daily. The intensity of the applied damaging stress might be evaluated with an integrated stress gauge during follow-up visits. A prototype of an electronic model enables us to measure the correlation involving the applied negative stress as well as the elevation from the anterior chest wall.
Since 2003, approx. 450 patients amongst 2 to 61 years of age began the VB therapy. Age and gender specific variations, depth of PE, symmetry or asymmetry, and concomitant malformations which include scoliosis and/or kyphosis influence the clinical course and achievement of VB therapy. As outlined by our experience, we see 3 distinctive groups of sufferers. Immediate elevation in the sternum was confirmed thoracoscopically throughout the Nuss process in each patient.
The VB therapy has been established as an option therapeutic option in chosen sufferers suffering from PE. The initial results up to now are encouraging, but long-term benefits comprising a lot more than 15 years are so far lacking, and further evaluation and follow-up studies are necessary.
