We read with great interest the article by Bond et al. regarding results of pectus excavatum correction using a modified minimally invasive approach with subxyphoid incision and three-point fixation . The authors demonstrated safety and excellent outcomes with the procedure comparable to the standard Nuss procedure. Interestingly, since 1999, our institution modified the minimally invasive Nuss procedure to include a subxyphoid incision, as described by the author. However, we utilize a two-point fixation. Our institution recently reviewed our experience with the modified Nuss procedure. In our analysis of 554 patients over a 15-year period, our rate of bar repositioning for rotation was < 1% and our rate of stabilizer removal due to chronic discomfort was similarly low at 1.4% . We have also not encountered any cardiac injury or required multiple bars. We have occasionally used a single stabilizer with no increase in the incidence of bar displacement in this cohort (unpublished data).
The authors in their article describe a three-point fixation compared to the standard two-point fixation. The cited rate of bar displacement in their study was 2.7%. As mentioned earlier, our rate of bar displacement with the two-point fixation was 1.4%, lower than that in this study. The inclusion of a third fixation point as described by the author, therefore, may be unnecessary and possibly eliminated to further simplify the steps of the procedure during placement. More so, opening the third (subxyphoid) incision may be required during bar removal, if the fixation has to be released. This will potentially not be required with a two-point fixation.
We again compliment the authors on their excellent article and thank them for their contribution to it.
