Video-assisted thoracic surgery (VATS) lobectomy for typical bronchopulmonary carcinoid tumors

Abstract

Background: Indications for the use of video-assisted thoracic surgery (VATS) lobectomy are a controversial matter. This study aims to provide a retrospective evaluation of VATS lobectomy in typical bronchopulmonary carcinoids.

Methods: Patient selection criteria for VATS lobectomy were as follows: (a) typical carcinoids with clear diagnosis; (b) centrally located lung tumors not amenable to bronchial resection with bronchoplastic procedures, or tumors located in peripheral lung tissues; (c) no hilar or mediastinal lymph node enlargement; and (d) normal respiratory function. Between January 1995 and December 1999, 12 patients (eight men and four women with a mean age of 57 years) were treated, seven with a peripheral and five with a centrally located tumor. Preoperative examination included chest roentgenograms, computed tomography (CT) of the chest, bronchoscopy, and spirometry; diagnosis was established by direct bronchoscopy in five cases, transbronchial biopsy in two cases, transthoracic biopsy in two cases, and videothorascopic wedge resection in three cases. Eleven VATS lobectomies and one VATS bilobectomy were performed. All patients underwent hilar lymphadenectomy and mediastinal sampling.

Results: There were no intraoperative complications. The only postoperative complication, hematothorax (8.3%), required VATS reoperation. Mean postoperative hospital stay was 5.33 days. Pathological examination of the resected specimens confirmed that the procedure was radical in all 12 patients and revealed eight T1N0 and four T2N0. At a mean follow-up of 30 months, no signs of recurrence were recorded.

Conclusion: VATS lobectomy in the treatment of selected typical carcinoids, both central and peripheral, seems to yield favorable results and is therefore preferable to thoracotomy since it is less invasive.
