Initial experience with video-assisted thoracoscopic bronchoplasty

Abstract

OBJECTIVES: Bronchial-origin involvement by endobronchial tumours or direct invasion by tumour or metastatic lymph nodes is a relative contraindication for video-assisted thoracoscopic (VATS) lobectomy. However, selected cases can be resected by VATS bronchoplasty. METHODS: Between 2006 and 2009, 21 of 231 (9.1%) VATS lobectomy cases underwent VATS bronchoplasty. Cases with endobronchial involvement and limited non-bulky invasion of bronchus by tumour or metastatic nodes without major vascular invasion were selected for bronchoplasty by preoperative bronchosocpy and CT scan thorax. Patients underwent a simple/wedge bronchoplasty (bronchus divided at origin and closed flush or transversely), sleeve bronchoplasty or others (bronchoplasty combined with other extended resections). All bronchoplasties were done totally endoscopically by directly watching a TV monitor. Bronchial margins were all subjected to intraoperative pathological analysis. Anastomosis was done with interrupted sutures. Integrity of anastomosis was checked by intraoperative bronchoscopy. The follow-up was done by 6-monthly CT scans and bronchoscopy. RESULTS: Eleven patients were females. Mean age was 64.9 years (range, 47-83 years). Indications were endobronchial tumours in 3, direct invasion in 6 and metastatic nodes in 12. In 4 cases, invasion was detected at the time of surgery. Mean hospital stay was 5.2 days (range, 3-8 days). Mean duration of surgery was 287 min (range, 135-540 min). Nine had simple/wedge bronchoplasty, 8, sleeve bronchoplasty and 4, extended bronchoplasties. Histology was non-small-cell carcinoma (NSCLC) in 19, carcinoid in 1 and colonic metastasis in 1. In the NSCLC, 5 patients were in stage IB, 5 in stage IIA, 2 in stage IIB and 7 were in IIIA. All bronchial margins were negative for malignancy. The mean follow-up was 26.2 months (range, 6-32 months). There was no operative mortality, but 1 patient developed bronchopleural fistula. To date, there have been no local tumour recurrences. CONCLUSIONS: Selected endobronchial and non bulky tumours with limited invasion at bronchial origin can be resected by VATS bronchoplasty. © The Author 2013.
