Description

Sleeve segmentectomy for central-type squamous cell carcinoma of the lung was performed in three patients with impaired lung function. All patients were male, and their preoperative FEV1.0 (FEV1.0%) was 1,070 ml (37.8%), 1,020 ml (41.0%), and 1,240 ml (51.2%), respectively. Since the predicted postoperative FEV1.0 after lobectomy was estimated to be less than 700 ml/m2 in each case, sleeve segmentectomy was performed to preserve the lung function as much as possible. The surgical procedures were S6 segmentectomy with bronchoplasty, sleeve segmentectomy of the left superior segment, and sleeve segmentectomy of the left apical segment (S1+2). The pathological stage was I B, II B, and I A. Two patients were alive without any evidence of recurrence fifty and eighty-one months after surgery. One patient died of gastric cancer without the recurrence of lung cancer.
