Abstract
OBJECTIVE: Surgical repair of pectus excavatum (PE) in childhood is a well-established procedure. Previously used operative techniques to correct PE were largely based on the Ravitch technique. Since about 10 years, the minimally invasive repair (MIRPE) by Nuss is well established. Conservative treatment with the vacuum bell to elevate the funnel in patients with PE represents a potential alternative to surgery in selected patients. METHODS: A suction cup is used to create a vacuum at the anterior chest wall. Three different sizes of vacuum bell exist which are selected according to the individual patients age. When creating the vacuum, the lift of the sternum is obvious and remains for a different time period. The device should be used for a minimum of 30 min (twice/day), and may be used up to a maximum of several hours daily. RESULTS: One hundred and thirty-three patients (110 males, 23 females) aged from 3 to 61 years (median 16.21 years) used the vacuum bell for 1 to a maximum of 36 months. Computed tomographic scans showed that the device lifted the sternum and ribs immediately. In addition, this was confirmed thoracoscopically during the MIRPE procedure. One hundred and five patients showed a permanent lift of the sternum for more than 1 cm after 3 months of daily application. Thirteen patients stopped the application and underwent MIRPE. Relevant side effects were not noted. CONCLUSION: The vacuum bell has proved to be an alternative therapeutic option in selected patients suffering from PE. The initial results proved to be dramatic, but long-term results are so far lacking, and further evaluation and follow-up studies are necessary.
