NUSS surgery is performed by thoracoscopically assisted placement of an orthopedic plate to lift the sternum and maintain the extension and flexibility of the chest, which is simple, minimally invasive, with short operative time and low bleeding, and is widely recognized by physicians and patients. However, whether minimally invasive treatment can be performed again for patients with recurrent funnel chest after conventional surgery has not been reported. From June 2006 to July 2010, we performed thoracoscopic minimally invasive Nuss surgery on 32 patients with failed or recurrent conventional surgery and achieved good results. Case data: All 32 cases were male patients, aged 7 to 17 years, with an average age of 14.6 years. 23 patients had undergone sternal lift surgery, 9 had undergone sternal reversal surgery, and were aged 3 to 15 years at the time of initial repair. RESULTS: All 32 patients completed the surgery successfully under thoracoscopy; the operation time averaged 76 min, longer than the initial Nuss operation; the intraoperative blood volume was only 20-50 ml, and none of them required blood transfusion; no intraoperative or postoperative complications occurred. At follow-up: 3 to 20 months, all patients had disappeared from preoperative symptoms, increased exercise tolerance, and relief of cardiac compression and cardiac displacement. Conclusion: The modified NUSS procedure is suitable for most patients with postoperative recurrence of funnel chest and provides a good option for minimally invasive surgery for these patients again.
