Carinal Resection and Reconstruction for Locally Advanced Primary Lung Cancer: Institutional Report

Abstract

Carinal resection and reconstruction for lung cancer, termed carinaplasty, is a rare operation, and the procedure remains challenging and few reports have been presented. We analyzed complications, local control, and manner of recurrence in patients who underwent a carinaplasty and compared the results to those who underwent an ordinary bronchoplasty. Among 766 patients who underwent surgery for primary lung cancer at our institutions, 82 bronchoplasty procedures were performed, while 6 of those who received a bronchoplasty underwent a carinaplasty. Three of 6 patients who received a carinaplasty underwent the montage method, and other 3 patients underwent the one-stoma method. There were no operative deaths in patients who underwent a carinaplasty, while there was 1 operative death in the group of patients who underwent an ordinary bronchoplasty. Complications in the anastomotic site were observed in 33% in the carinaplasty group and 5.3% in the ordinary bronchoplasty group (P=0.011). There was no significant difference in regard to local recurrence between the groups (P=0.620). In conclusion, our results show that a carinaplasty is a technically demanding but useful procedure to avoid a pneumonectomy in patients with locally advanced lung cancer.
