Extended Bronchoplasty Anastomosed between the Left Main and the Superior Segmental Bronchi for Locally Advanced Left Upper Lobe Lung Cancer with Invasion of the Basal Segment

We report a case of extended bronchoplasty in which anastomosis between the left main and the superior segmental bronchi with resection of the left upper lobe and basal segment was required to avoid pneumonectomy for locally advanced lung cancer. The main tumor located at the left upper lobe invaded the basal segment, and involved both the basal pulmonary artery and left secondary carina. Regarding anastomosis, the bronchi were cut in a deep wedge shape and a wall flap was made by part of the lower lobar bronchus. The patient’s postoperative course was uneventful and he has been alive without recurrence for more than 3 years after surgery.
