In brief
Large single-institution review of 600 MIRPE cases shows 18% complication rate, with significant improvement after 2013 (15.3% vs 28.2%) as surgeons progressed through learning curve. Bar displacement remains the primary unresolved challenge despite technical modifications, while severe complications including bleeding and lung injury can occur during bar removal.

Abstract
Background/Purpose
: Complication risk in minimally invasive repair of pectus excavatum (MIRPE) is not negligible, particularly during learning curve. We reviewed the complications of a large series, evaluated the correlation with technical details and learning curve, and presented the strategies implemented to reduce them.
Methods
: Data on MIRPE patients from 2005 to 2020 (divided in two groups: before and after 2013) were collected prospectively and reviewed. Complications were correlated to the number and type of bar/stabilizers, and to the surgeon learning curve.
Results
: We placed 783 bars (484 Biomet, 273 Intrauma and 26 others) in 600 patients and removed 524 bars in 436 patients. Complications occurred in 108 MIRPE (18%): 3.7% intraoperative, 14.3% postoperative. No cardiac perforations were reported; in the second period we had fewer complications (15.3% versus 28.2%) particularly in intraoperative ones (0.3% versus 9%), the intervention was faster (64 versus 83 min and 92 versus 127 for 1 and 2 bars) and hospitalization shorter (5 versus 7.5 days). Complication rate of bar removal was 2.7% (all Biomet bars): one intra-thoracic bleeding and 2 lung injuries.
Conclusions
: MIRPE has a significant rate of complication, especially during learning curve. Postoperative complications are more frequent and less dependent on learning curve. Severe complications can be observed during bar removal. We have adopted new bars to reduce complications, but dislocation remains an unresolved problem.
