Objective:
The Nuss procedure is a minimally invasive approach used to treat the pectus excavatum. One to three curved metal bars are inserted behind the sternum in order to push it into a normal position. A bilateral thoracoscopy, with 3 or 4 incisions on each side, has been reported as a safe method to repair the chest. The aim of this observational cohort study is to evaluate the safety and efficacy of the modified uniportal thoracoscopic Nuss procedure.
Patients And Methods:
A retrospective review on 248 consecutive patients treated in Southern Switzerland in the last 5 years for chest deformity was performed. Conservative treatment with vacuum bel or dinamic compression was performed in 235 cases. Thirteen patients with pectus excavatum were surgically treated with a modified single-incision thoracoscopic approach and introduction of a single retrosternal Nuss Bar. Demographics, clinical characteristics, surgical data and results were analyzed and discussed.
Results:
The male/female ratio was 11/2, with mean age of 20.75 (±5.05) years. The Haller index was 3.65±0.5. The operative duration was 68. 2±13.3 min and hospitalization stay ranged from 2 to 10 days. There was no instance of intraoperative cardiac perforation or macrovascular injury. No pleural effusion or infection was reported. The overall complication rate after a postoperative follow-up of 24.6±3 months was 7.6%, without mortality, major bleeding, infectious complications, displacement or recurrence. Patients satisfaction and postoperative pain were also analyzed.
Conclusions:
The modified single-incision thoracoscopic Nuss procedure is both safe and effective for pectus excavatum correction with non-recurrence after two years.
