[Retrograde S(9+)10 Segmentectomy without Interlobar Fissurelectomy].

Backgrounds: With increase of patients with a small-sized lung cancer, there is an increasing need for minimally invasive lung segmentectomy that can preserve respiratory function. We perform S(9+)10 segmentectomy with retrograde dissection of the pulmonary vein, bronchus, pulmonary artery, in order, without interlober fissurelectomy and staple dissection of the peripheral lung parenchyma.

Methods: Seven patients who underwent retrograde S(9+)10 segmentectomy between June, 2021 and May, 2022 in our hospital were retrospectively reviewed.

Diaphragmatic paraganglioma protruding into the right thoracic cavity.

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.

Incidental haemothorax after sublobar resection: did staple line scratch chest wall?

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.

Successful treatment of post-operative peripheral bronchopleural fistulas using endobronchial Watanabe spigots.

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.

Bronchoscopic observation with linked colour imaging.

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.

Penetration of bronchial wall by knot of absorbable monofilament suture.

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.

Rapid detection of microbes in the dialysis solution by the microcolony fluorescence staining method (Millflex quantum).

A chemiluminescence system, Milliflex Quantum (MFQ), to detect microcolonies, has been used in the pharmaceutical field. In this study, we investigated aquatic bacteria in hemodialysis solutions sampled from bioburden areas in 4 dialysis faculties. Using MFQ, microcolonies could be detected after a short incubation period.
