Wedge extended bronchoplasty with caliber adjustment by membranous suture.

Abstract

Extended bronchoplasty for the left lower lobe lung tumors with interlobar lymph node involvement is a useful surgical technique for avoiding pneumonectomy. Typically, sleeve bronchoplasty, in which the superior division bronchus and the left main bronchus are separated and anastomosed, is chosen due to the difference in caliber of the anastomosis; herein, we report a wedge extended bronchoplasty in which the superior division bronchus and the left main bronchus were not completely separated. The main point of this technique is to adjust the difference in caliber by suturing the main bronchial membranes.
