Sleeve lobectomy for bronchogenic carcinoma is an alternative to pneumonectomy. The extent and location of the tumor must be such that a sleeve procedure is feasible. The conservation of lung tissue benefits both compromised and uncompromised patients. From August 1988 to March 1989, five patients underwent sleeve lobectomy for bronchogenic carcinoma of the lung. The patients included four males and one female ranging in age from 52 years to 66 years. All patients were diagnosed as having squamous cell carcinoma. Operative procedures were right upper sleeve lobectomy in four cases and left upper sleeve lobectomy with pulmonary angioplasty in one case. Complications developed in one patient. An asthmatic attack necessitated ventilator support for one day. Bronchoscopic examinations were performed at two weeks and three months postoperatively in four patients. Anastomosis sites on all patients were intact, but in one case, nodules were noted. Pulmonary function tests were also checked at three months postoperatively, and showed good results. The reimplanted lobe or lobes contribute significantly to the overall remaining lung function. All patients are being followed up with satisfactory results, except one case of suspected local tumor recurrence. We think, therefore, that sleeve lobectomy is a safe and adequate procedure for patients with resectable lung cancer.
