Descending necrotizing mediastinitis is a critical infection and the mortality rate remains high. Early aggressive surgical drainage and antibiotic therapy are essential for treatment. We evaluated the efficiency of transthoracic drainage using a minimally invasive technique in 11 cases of descending necrotizing mediastinitis between May 2002 and March 2008. We performed a right-side minithoracotomy with thoracoscopic assistance, and the mediastinum was thoroughly drained. The length of hospitalization ranged from 30 to 117 days. The postoperative course was good in all patients, and the outcome was favorable. All patients were discharged without major complications. We recommend employing a minithoracotomy with thoracoscopic assistance for aggressive treatment of descending necrotizing mediastinitis.

A resected lung weight ≥1.5 g was only significant risk factor of POBN in patients with PSP.

PulLE has cosmetic benefits over cVATS and is easy to perform. We believe our novel procedure has the potential to become the standard operative treatment for PSP.

The surgical results of mPulLE in patients with PSP with multiple lesions were equivalent to those achieved with three-port VATS under the same conditions.
