Summary

Background

For the correction of pectus excavatum (PE) deformities in adolescents, adults, and generally in asymmetric cases, a semi-open approach called the MOVARPE (minor open videoendoscopically assisted repair of pectus excavatum) technique is used, consisting of standard pectus bar implantation hybridized with auxiliary sternum osteotomy and multiple chondrotomies. In this study, we report our experiences, discuss pros and cons, and provide technical refinements.

Methods

Between September 2005 and March 2015, 61 patients were selected to undergo the MOVARPE instead of the standard MIRPE (minimally invasive repair of pectus excavatum) procedure because of age or specific morphologic characteristics of PE. Patient age ranged from 14 to 45 years (mean 23.4 years).

Results

Auxiliary incisions for skeletal relaxation enabled symmetric remodeling and, in most cases, circumvented the need for a second pectus bar. The bars were left in position for a mean of 19.3 months (range: 12 to 35 months). There were no major complications. Minor complications such as pleural effusion, temporary pneumothorax, and mild recurrence of the deformity after bar removal were seen at rates similar to those for standard techniques. In the current study reporting outcomes of the previously described MOVARPE procedure, the authors saw no evidence of a possible disadvantage in the overall concept or execution of the procedure for the suggested indication.

Conclusion

From this experience, we can state that, as an alternative to the MIRPE technique, MOVARPE is a method that offers high efficacy, particularly for rigid and complex pectus excavatum deformities at or beyond puberty.
