Three cases of sleeve segmentectomy for central-type squamous cell carcinoma with impaired lung function due to COPD

Abstract

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 FEV_1.0 (FEV_1.0%) was 1,070 ml (37.8%), 1,020 ml (41.0%), and 1,240 ml (51.2%), respectively. Since the predicted postoperative FEV_1.0 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.
