Post‐operative peripheral bronchopleural fistulas (BPF) are sometimes caused by post‐operative pneumonia and empyema. Conservative treatment options such as administration of antibiotics and chest tube drainage can have limited outcomes in certain cases. Bronchial occlusion is an effective treatment option if the target bronchi for BPF are identified. This case study describes a successful bronchial occlusion for peripheral BPF with endobronchial Watanabe spigots (EWSs) and a digital drainage system. This case involved a 70‐year‐old man who developed a post‐operative peripheral BPF after a left upper lobectomy. Bronchial occlusion with EWS was performed because the target bronchi responsible for BPF were clearly detected by a chest computerized tomography scan. The effectiveness of the occlusion was confirmed with the use of a digital drainage system immediately after the procedure was completed. The chest tube was removed one week following the bronchial occlusion procedure.

We report two cases of the comparison of diagnosis made with linked color imaging (LCI) and conventional white‐light imaging (WLI) on the same patients. In case 1, a 75‐year‐old man in whom right upper lobectomy with mediastinal lymph node dissection was performed due to lung cancer had signs of bronchitis on postoperative day 8. The LCI demonstrated slight inflammatory changes that were not detectable with the conventional WLI on the tracheal wall. In case 2, in a 61‐year‐old woman who was diagnosed with adenoid cystic carcinoma, the bronchial wall was checked to confirm the extent of the tumour. The submucosal vascularity and tumour margin on the bronchial mucosa were better visible on LCI than on WLI. We could easily detect the mucosal inflammatory lesion and the malignant lesion with LCI in comparison with conventional WLI. Both mucosal inflammatory and malignant lesions were better visible with LCI in comparison to WLI.

We herein report a case of life-threatening haemothorax that occurred 40 days after pulmonary segmentectomy in a 60-year-old man. The patient uneventfully underwent resection of the apical and posterior segments of the right upper lobe by video-assisted thoracic surgery for early-stage lung cancer. An emergency operation of haemostat for active bleeding from the intercostal artery was successful via a right thoracotomy. The bleeding point was in the vicinity of the staple line dividing the intersegmental plane. This case reveals that scratch by staples can cause haemothorax through incidental injury of the intercostal artery.

A 75-year-old man underwent thoracoscopic left upper lobectomy for primary lung cancer. Additional ligature plication to the left superior pulmonary vein with absorbable monofilament suture was performed after stapling with an endostapler. Postoperative bronchoscopy revealed penetration of the monofilament thread edge eviscerating across the wall of the left main bronchus. The edge was spontaneously absorbed with no adverse events. Penetration of a thick monofilament thread edge into mediastinal organs should be considered when the thread is located in the mediastinum.

Paragangliomas in the diaphragm are extremely rare. We report the case of a 27‐year‐old woman with a nonfunctioning paraganglioma protruding superiorly from the right diaphragm. The patient underwent an anterior thoracotomy, and a supradiaphragmatic tumor (70 mm in diameter), which compressed the inferior vena cava and the right hepatic vein, was completely resected by combined partial resection of the right diaphragm and pericardium. To our knowledge, this is the first report of a paraganglioma situated both on the diaphragm and close to the inferior vena cava and hepatic vein. Key points
