Abstract

BackgroundResearch into multiple-bar Nuss operations for the treatment of wide-range or significantly asymmetric pectus excavatum is rarely reported. This paper aims to explore the curative effects of multiple-bar Nuss operations on wide-range or significantly asymmetric pectus excavatum.MethodsWe reviewed the clinical data of 153 patients with pectus excavatum who were treated in our hospital from September 2006 to August 2014. All the patients had wide-range or significantly asymmetric pectus excavatum and underwent multiple-bar Nuss operations performed by the author.ResultsAll 153 patients agreed to undergo the operation. The median age was 17 y (10.2–41 y). The median Haller index was 3.98 (3.2–25). One hundred and fifty-one patients accepted treatment with two bars, and 2 cases accepted treatment with three bars. The median operation time was 123 min (65–500 min), the median blood loss was 20 mL (2–200 mL), and the median postoperative hospital stay was 6 days (3–33 days). The incidence rates of pleural effusion, pneumothorax and hydropneumothorax that required drainage treatment were 0.7% (1/153), 1.3% (2/153) and 3.3% (5/153), respectively. Displacement of a bar occurred in one case, and bar exposure occurred in 7 cases. Therefore, 2 cases had the bars removed early, within 2 years postoperation. One patient with severe depression (Haller index: 8.8) had an unhealed auxiliary incision of the xiphoid process, and although the incision was cured after the early removal of the inferior bar, the deformity recurred. There were no cases of death. Currently, 51.6% (79/153) of the cases have had the bars removed. The most recent follow-up revealed that patients’ median satisfaction score for the surgical correction effect was 9 points (10 points indicated full satisfaction).ConclusionsFor patients with significantly asymmetric and severely deformed pectus excavatum, the multiple-bar Nuss operation not only is safe and effective but can also achieve a better cosmetic appearance. However, we should continue to explore technical improvements.
