Right S⁶ segmentectomy with flap bronchoplasty for endobronchial hamartoma

Abstract

A 62-year old man was admitted to our hospital for the further investigation of abnormal chest shadows. Chest CT revealed multiple granular shadows in the right lower field and a nodule in the superior segment (S⁶) of the right lower lobe. Bronchoscopy confirmed an endobronchial tumor in the superior branch (B⁶) of the lower bronchus protruding into a lower lobe bronchus. No definitive histological diagnosis was obtained preoperatively. Because the location of the tumor stalk was not confirmed bronchoscopically, we planned an operation. To preserve the middle lobe and basal segment, we decided to perform S⁶ segmentectomy with flap bronchoplasty. In the operation, we preserved the superior wall of B⁶ as a flap and, following S⁶ segmentectomy, the defect of the lower lobe bronchus was closed using the flap. The postoperative course was uneventful, and brochoscopic findings revealed favorable healing of the suture line and no stenosis.
