Left secondary carinal resection and reconstruction for low-grade bronchial malignancies.


ABSTRACT:

Objectives

A rare and complex procedure, total lung sparing left secondary carinal resection and reconstruction is only performed in a few specialized centers in a restricted group of patients. We reviewed our experience to evaluate its safety.

Methods

Patients who underwent left secondary carinal resection and reconstruction with complete lung parenchymal preservation for low-grade bronchial malignancies at the Shanghai Chest Hospital and the Padua University Hospital were retrospectively reviewed. Clinicopathologic factors and perioperative outcomes were analyzed.

Results

Thirty patients underwent the procedure between July 2012 and July 2019 (mean age, 42.9 years). No operative mortality occurred and postoperative complications developed in 4 patients (13.3%), including pneumonia (n = 3 [10.0%]), subcutaneous emphysema (n = 2 [6.7%]), and prolonged air leak (n = 2 [6.7%]). Pathologies included adenoid cystic carcinoma (n = 11), mucoepidermoid carcinoma (n = 6), carcinoid tumors (n = 9 [8 typical and 1 atypical subtypes]), inflammatory myofibroblastic tumor (n = 3), and myoepithelioma (n = 1). The margins were positive in 8 patients (26.7%), whereas 2 patients (6.7%) had positive lymph nodes. Adjuvant therapies were performed postoperatively, including chemoradiotherapy for positive lymph nodes and radiotherapy for positive margins.

Conclusions

Total lung sparing left secondary carinal resection and reconstruction can be performed safely in well-selected and oncologically appropriate patients with low-grade bronchial malignancies.
